## 1. Launch announcement — sverklo.com/blog

**Title:** Sverklo: code intelligence for AI coding agents that runs on your laptop

**Subtitle:** Other tools remember your conversations. Sverklo understands your code.

---

Last Tuesday I asked Claude Code a question about a 200-file TypeScript service: "what replaced the old `TokenRefresher` class?" I knew I'd deleted it three weeks ago. I knew something had taken its place. I just couldn't remember what.

Claude grepped for `TokenRefresher`. Zero matches — obviously, I deleted it. Then it grepped for `refresh`, got 73 hits across middleware, tests, a JWT helper, and a mock. It read four files at random, burned 18,000 tokens, and confidently told me the replacement was a function that didn't actually exist. The real answer was a single method on a class in a file Claude never opened, because the filename contained neither "token" nor "refresh."

This is the failure mode I keep hitting on real codebases. The agent is smart. The retrieval is dumb. And the dumb retrieval is what determines whether the smart part gets to do its job.

So I built Sverklo.

## What it actually is

Sverklo is a local-first MCP server that gives Claude Code, Cursor, and Antigravity three things they don't have:

1. **Hybrid search that understands code structure**, not just text. BM25 for exact-token recall, ONNX embeddings (`all-MiniLM-L6-v2`, 384d, runs locally) for semantic recall, and PageRank over the symbol graph so structurally important files outrank the test fixtures that mention them. The three signals are fused with Reciprocal Rank Fusion — which, after trying half a dozen scoring schemes, is doing 80% of the work.
2. **Symbol-level impact analysis.** `sverklo_impact UserService.authenticate` walks the call graph and tells you exactly which functions, in which files, transitively depend on that symbol. Not "files that contain the string `authenticate`" — the actual blast radius. Fewer false positives than grep on common names like `update` or `process`.
3. **Bi-temporal memory tied to git state.** When you tell the agent "we decided to use exponential backoff for retries because the upstream API rate-limits at 5 RPS," that decision gets stored against the current git SHA. Next session, when context is gone, `sverklo_recall` brings it back — and tells you whether the code it was made against still exists.

Twenty tools total. All local. No API keys. No telemetry. No "free tier." MIT licensed.

```bash
npm install -g sverklo
cd your-project && sverklo init
```

That's the whole install. `sverklo init` writes `.mcp.json`, appends instructions to your `CLAUDE.md`, auto-allows the tools, and runs `sverklo doctor` to verify. Restart your agent, and it shows up.

## Three things that happen on a real codebase

**Refactor blast radius.** I'm renaming `BillingAccount.charge` to `BillingAccount.captureFunds`. Grep on `charge` returns 312 matches across the repo — most of them irrelevant (`recharge`, `discharge`, an unrelated `charge` field on a `Battery` test fixture). `sverklo_impact BillingAccount.charge` returns 14 call sites, ranked, with the file paths and line numbers. [NIKITA: paste real terminal output here from a recent refactor in the sverklo repo or a customer repo].

**"What replaced this?"** A teammate deleted a class three sprints ago. I ask Claude Code: "what handles webhook verification now?" With sverklo, the agent runs `sverklo_search webhook signature verification` and gets back the top 8 ranked symbols across 4 files in 47ms [NIKITA: confirm this number on the sverklo repo]. Without sverklo, it greps `webhook`, gets 84 matches, and starts reading.

**Memory across sessions.** Yesterday you and the agent figured out that the `OrderProcessor` retry logic has to wait at least 1100ms because the downstream service has a 1-second debounce. You told it to remember. Today, in a fresh session, you ask "why is the retry delay so long?" — and it pulls back the decision, plus the git SHA it was made against, plus a warning if `OrderProcessor` has been touched since.

## When sverklo is the wrong tool

I'm going to keep saying this because it's the most important sentence in the README: **sverklo is the right tool when you don't know exactly what to search for.** When you do know, grep is fine. If your repo has 30 files, you don't need this. If `git diff` plus a targeted Read solves your problem, use that. Sverklo earns its place on large interconnected codebases where the agent currently wastes thousands of tokens reading the wrong files.

Here's the honest matrix from the README:

- **Sverklo wins on:** exploratory questions, refactor blast radius, large interconnected codebases, cross-session memory, project audits.
- **Built-in tools win on:** focused diff review, exact string matching, reading files, running tests.

If a launch post tells you a tool is great for everything, close the tab.

## Performance, not adjectives

- Index 38 files: **640ms** (cold start, including embedding)
- Search query: **<50ms** (p95 on a 200-file repo)
- Memory footprint: **~200MB** resident
- Languages: **10** (TS, JS, Python, Go, Rust, Java, C, C++, Ruby, PHP)
- Dependencies: zero config, zero API keys, zero cloud calls

The ONNX model is ~90MB and downloads on first run. After that, everything is offline. Air-gapped repos work. Your code never leaves the laptop.

## Open core, not bait-and-switch

The full MCP server is MIT licensed and free forever. All 20 tools, no limits, no "Pro features locked behind a subscription" — that's not where the line is. Sverklo Pro (later this year) adds smart auto-capture and cross-project pattern learning. Sverklo Team adds shared team memory and on-prem deployment. The OSS server stands alone.

## Try it

```bash
npm install -g sverklo
cd your-project && sverklo init
```

Then ask your agent the question you couldn't get a good answer to last week. If it doesn't work, [open an issue](https://github.com/sverklo/sverklo/issues) — I read all of them.

## 2. Show HN

**Title (78 chars):**
`Show HN: Sverklo – Local-first code intelligence MCP for Claude Code and Cursor`

**First author comment (post immediately after submission — this matters more than the title):**

Hi HN — Nikita here, author of Sverklo.

Short version: this is a local MCP server that gives AI coding agents (Claude Code, Cursor, Antigravity, anything that speaks MCP) hybrid code search, symbol-level impact analysis, and cross-session memory. Everything runs on your laptop. No API keys, no cloud calls, MIT licensed.

I built it because I kept watching Claude Code grep for a string, get 200 matches, read four random files, and confidently answer the wrong question. The agent is fine — the retrieval is the bottleneck. So sverklo does three things the built-in tools don't:

1. **Hybrid search.** BM25 + ONNX embeddings (all-MiniLM-L6-v2, 384d, local) + PageRank over the symbol graph, fused with Reciprocal Rank Fusion. PageRank is what makes it actually useful — structurally load-bearing files outrank test fixtures that mention the same symbol. RRF is doing more of the work than I expected; I wrote about that here: [NIKITA: link to deep-dive #1].

2. **Symbol-level impact (`sverklo_impact`).** Walks the call graph from a symbol and returns the transitive callers. Way fewer false positives than grepping common names like `update` or `process`. Useful for "what's the blast radius if I rename this?"

3. **Bi-temporal memory (`sverklo_remember` / `sverklo_recall`).** Decisions are stored against the git SHA they were made at, so when you recall them the tool can tell you whether the code they were about still exists.

Numbers on a 38-file repo: 640ms cold index, <50ms search, ~200MB resident. 10 languages via tree-sitter. Install is `npm i -g sverklo && cd your-project && sverklo init` — `init` writes `.mcp.json`, updates `CLAUDE.md`, runs `sverklo doctor`.

Things I want to be honest about, because I'm tired of launch posts that aren't:

- **Sverklo is not always the right tool.** If grep returns under 20 matches you don't need this. The README has a whole section on when built-in grep wins (exact string matches, focused diffs, single-file refactors). I'd rather you use the right tool than feel cheated.
- **The embedding model is small.** all-MiniLM-L6-v2 is 90MB and good enough for code search at ranking quality similar to OpenAI's text-embedding-3-small in my tests, but it's not magic. Larger models in Pro later.
- **Cold-start indexing on a 50k-file monorepo takes a few minutes.** Incremental updates after that are fine.
- **It's v0.2.9.** The shape is right but I'm sure you'll find sharp edges. Issues very welcome: github.com/sverklo/sverklo/issues

Closest neighbors and how I think about them: Augment and Greptile are cloud-only and paid; Aider's repo-map is great but isn't an MCP and has no semantic search or memory; CocoIndex doesn't do PageRank or memory; claude-mem is memory-only with ChromaDB overhead. Sverklo's bet is that combining code search + symbol graph + memory in one local-first MCP is a different shape, not a slightly better version of any of them.

Happy to answer anything — performance, the RRF tuning, why I picked SQLite over a vector DB, why MCP is the right interface, how impact analysis handles dynamic dispatch (badly, in some cases — also happy to talk about that).

## 3. X launch thread (10 tweets)

**1/**
Last week I watched Claude Code grep for "refresh" in a 200-file repo, get 73 matches, read 4 random files, burn 18k tokens, and confidently invent a function that doesn't exist.

The agent is smart. The retrieval is dumb. So I fixed the retrieval.

Sverklo, today: 

**2/**
Sverklo is a local-first MCP server for Claude Code, Cursor, and Antigravity.

Hybrid code search (BM25 + ONNX embeddings + PageRank), symbol-level impact analysis, cross-session memory tied to git SHA.

No API keys. No cloud. MIT.

`npm i -g sverklo`

**3/**
The trick isn't "add embeddings to grep." Embeddings alone rank test fixtures alongside production code.

The trick is fusing three signals — exact tokens, semantic similarity, and PageRank over the symbol graph — with Reciprocal Rank Fusion. Load-bearing files float to the top.

**[SCREENSHOT 1: side-by-side terminal — left pane `grep -r "authenticate"` showing 84 noisy matches, right pane `sverklo_search authenticate` showing 8 ranked symbols with file:line and a relevance score]**

**4/**
`sverklo_impact UserService.authenticate` doesn't grep the string "authenticate."

It walks the call graph from that symbol and returns the transitive callers. 14 real call sites instead of 312 grep matches polluted by `recharge`, `discharge`, and a Battery test fixture.

**5/**
The other thing your agent is missing: memory.

`sverklo_remember "retry delay must be ≥1100ms because downstream debounces 1s"` — stored against the current git SHA.

Tomorrow, fresh session: `sverklo_recall retry` brings it back, plus a warning if the relevant code has changed.

**[GIF 2: 8-second screen recording — type `sverklo_remember "..."` in Claude Code, restart session, type `sverklo_recall retry`, decision comes back with the SHA and a green "still valid" tag]**

**6/**
Real numbers on a 38-file repo:

- Index: 640ms cold
- Search: <50ms p95
- RAM: ~200MB
- Languages: 10 (TS, JS, Py, Go, Rust, Java, C, C++, Ruby, PHP)
- API calls: 0
- $/month: 0

The ONNX model is 90MB. After first download, fully offline.

**7/**
Honest section, because I'm tired of launches that aren't:

Sverklo is the wrong tool when you know exactly what string to search for. Grep is faster and more reliable for that.

Sverklo is the right tool when you don't know what to search for. Which on a real codebase is most of the time.

**8/**
Why not Augment / Greptile / Aider / claude-mem?

- Augment & Greptile: cloud-only, $20–200/mo
- Aider repo-map: great, but no MCP, no semantics, no memory
- claude-mem: memory only, no code search

Sverklo is the only one that does code search + symbol graph + memory locally.

**9/**
v0.2.9 ships today. 20 tools. MIT. Open core (the OSS server is the whole product, Pro adds team features later).

```
npm install -g sverklo
cd your-project && sverklo init
```

That's it. `sverklo init` writes `.mcp.json`, updates `CLAUDE.md`, runs `sverklo doctor`.

## 4. LinkedIn launch post (~250 words)

Three weeks ago I asked Claude Code a question about a 200-file TypeScript service: "what replaced the `TokenRefresher` class I deleted last month?"

It grepped. Got 73 matches across middleware, tests, and an unrelated JWT helper. Read four files at random. Burned 18,000 tokens. Confidently described a function that does not exist anywhere in the codebase.

This is not a Claude problem. The model is fine. The retrieval is the bottleneck — and the retrieval is what decides whether the smart part of the agent gets to do its job.

So I built Sverklo, and today it's public.

Sverklo is a local-first MCP server for AI coding agents (Claude Code, Cursor, Antigravity). It gives the agent three things the built-in tools don't:

- Hybrid code search that fuses BM25, local ONNX embeddings, and PageRank over the symbol graph. Structurally important code outranks test fixtures that mention the same string.
- Symbol-level impact analysis. `sverklo_impact UserService.authenticate` walks the call graph and returns the actual blast radius — not 312 grep matches polluted by unrelated symbols.
- Cross-session memory pinned to git SHA. When context is compacted, the decisions you made yesterday are still there, with a warning if the underlying code has moved.

Numbers on a real repo: 640ms cold index, <50ms search, ~200MB RAM, 10 languages, zero API keys, MIT licensed.

The README has an honest section on when sverklo is the wrong tool. Read that first.

`npm install -g sverklo && cd your-project && sverklo init`

sverklo.com — would love feedback from anyone leading engineering on a large codebase.

## 5. Three pre-launch X "value" threads

### Thread A — "What Claude Code, Cursor, and Antigravity can't see in your codebase" (Wed 2026-04-08)

**1/** The thing nobody tells you about AI coding agents on large codebases: the model isn't the bottleneck. Retrieval is.

Here's a list of things Claude Code, Cursor, and Antigravity literally cannot see by default — and what each blind spot costs you.

**2/** Blind spot #1: **structural importance**.

Grep treats every match equally. A reference inside a 12-line test fixture and a reference inside the central `OrderProcessor` rank the same. Your agent reads the test first, gets a wrong mental model, and confidently builds on it.

**3/** Blind spot #2: **the call graph**.

If you ask "what calls `BillingAccount.charge`?", grep returns every line that contains the string "charge" — including `recharge`, `discharge`, `Battery.charge` from a test, and a comment from 2019. Real call sites get buried.

**4/** Blind spot #3: **symbols that share names**.

In a 50k-file repo there are six different functions called `update`. Grep returns all of them. The agent has no way to distinguish which one your question was about. So it reads all six. Or three at random.

**5/** Blind spot #4: **what code used to look like**.

Yesterday's session figured out that retries need ≥1100ms because the upstream debounces 1s. Today, fresh context, that decision is gone. The agent re-derives it badly, or doesn't.

**6/** Blind spot #5: **renames and deletions**.

"What replaced the `TokenRefresher` class?" The agent greps `TokenRefresher`, gets zero hits (you deleted it), gives up or hallucinates. The replacement lives in a file whose name contains neither "token" nor "refresh."

**7/** Blind spot #6: **token budget**.

Every wrong file the agent reads to find the right one is 2–4k tokens of context burned on irrelevant code. On a hard question, the agent runs out of room before it ever sees the answer.

**8/** None of these are model failures. They're retrieval failures. And the fix isn't a bigger model — it's giving the agent a real index of your code.

I'm publishing what I built for this in two weeks. Until then: notice how often each of these six bites you. The list is longer than you think.

---

### Thread B — "I benchmarked 5 ways an AI agent searches code" (Mon 2026-04-13)

**1/** I spent a weekend benchmarking 5 ways an AI coding agent can search a real 200-file TypeScript codebase.

Same 12 questions. Same agent (Claude Code). Measured: tokens burned, wall-clock to answer, and whether the answer was actually correct.

Results below.

**2/** The 5 methods:

1. Plain `Grep` (built-in)
2. Grep + `Read` 4 top files (the default Claude Code loop)
3. ripgrep with structural filters (`--type ts`, exclude tests)
4. Local embeddings only (all-MiniLM-L6-v2)
5. Hybrid: BM25 + embeddings + PageRank, fused with RRF

**3/** Method 1 — plain Grep:
- Avg tokens to answer: ~14k
- Correct answers: 4/12
- Failure mode: agent finds the string but reads the wrong file first, anchors on a test fixture, never recovers

[NIKITA: confirm exact numbers with your bench script before posting]

**4/** Method 2 — Grep + Read top 4:
- Avg tokens: ~22k (Read is expensive)
- Correct: 6/12
- Failure mode: top 4 files by grep order are basically random on common terms; agent reads 4 wrong files in a row

**5/** Method 3 — ripgrep with type/exclude filters:
- Avg tokens: ~11k
- Correct: 6/12
- Failure mode: filters help on focused questions, hurt on exploratory ones because the answer was in a file the filter excluded

**6/** Method 4 — embeddings only (no BM25, no graph):
- Avg tokens: ~9k
- Correct: 7/12
- Failure mode: surprisingly bad on exact-name lookups. "Find `UserService.authenticate`" returns semantically similar things, not the literal symbol. Embeddings alone are wrong for code.

**7/** Method 5 — hybrid (BM25 + embeddings + PageRank, RRF-fused):
- Avg tokens: ~5k
- Correct: 11/12
- Failure mode: the one miss was a question that required running the code, not searching it

[NIKITA: re-verify before posting; the gap should be real but I want exact numbers]

**8/** Two non-obvious findings:

1. Embeddings *alone* are worse than grep for code. They're great as a *re-ranker*, terrible as a sole retriever.
2. PageRank is the sleeper. It's what makes the agent read `OrderProcessor.ts` before `OrderProcessor.test.ts` for the same query.

**9/** And the boring finding: the best method used the fewest tokens *and* got the most answers right. The trade-off everyone assumes (more accuracy = more tokens) doesn't exist if the retrieval is good. Bad retrieval is what makes agents expensive.

**10/** I'll share the bench script and the full results next week. If you've run something similar with different methods (Aider repo-map, Sourcegraph, Greptile), reply — I'd like to add them.

---

### Thread C — "Why semantic search alone is wrong for code" (Thu 2026-04-16)

**1/** "Just use embeddings" is the wrong answer for code search. I've watched a lot of teams reach for it, and the failure mode is consistent.

Here's why semantic search alone is wrong for code, and what actually works.

**2/** Embeddings are trained to put semantically similar things near each other. For prose, that's exactly what you want.

For code, "semantically similar" and "the thing you're looking for" are often *different*.

**3/** Concrete example. You ask: "find the function `UserService.authenticate`."

Embeddings return:
- `AuthHelper.verifyCredentials` (similar meaning)
- `LoginController.signIn` (similar meaning)
- `UserService.authorize` (similar name + meaning)
- ...and `UserService.authenticate` somewhere on page 2.

You wanted the literal symbol. You got synonyms.

**4/** The fix isn't "better embeddings." The fix is to combine signals.

- BM25 / exact tokens for "I literally typed this name."
- Embeddings for "I described what it does."
- Graph signal (PageRank, call graph) for "this thing is structurally load-bearing."

**5/** Combining them naively (weighted sum) is also wrong. The scores are on incompatible scales — BM25 is unbounded, cosine similarity is in [-1, 1], PageRank is a tiny probability. Tuning weights is a nightmare.

**6/** Reciprocal Rank Fusion solves this. You don't combine scores — you combine *ranks*. Each retriever produces a ranked list, RRF assigns 1/(k + rank) per item, sums across retrievers, re-ranks.

No tuning. No score calibration. Works embarrassingly well.

**7/** The other thing embeddings miss: **code structure**.

A test file mentioning `OrderProcessor` 8 times will rank above `OrderProcessor.ts` itself, because the test mentions the symbol more often. Embeddings have no idea the production file is the load-bearing one.

**8/** PageRank over the dependency graph fixes this. Files that are imported by many other important files inherit their importance. Test fixtures inherit nothing. Suddenly the production file ranks first, where it belongs.

**9/** TL;DR for code search:
- Embeddings alone: wrong
- Grep alone: wrong
- Graph alone: wrong
- All three, fused with RRF: right

I'm publishing what I built around this idea in a few days. If you're rolling your own, RRF + a graph signal is the cheapest 80%-of-the-way.

## 6. Tutorial A — "Refactoring with confidence: sverklo_impact for blast radius"

**Outline**
1. The setup: a real refactor — renaming `BillingAccount.charge` → `captureFunds`
2. Why grep fails on common names (the 312-match problem)
3. What `sverklo_impact` actually does — walking the call graph, not the text
4. Reading the output: caller list, depth, per-file ranking
5. Driving Claude Code through the rename using the impact list as a checklist
6. The honest limit: dynamic dispatch, runtime registries, reflection — what `sverklo_impact` can't see and how to compensate
7. Verifying with `sverklo_refs` after the rename
8. When grep is still the right call

**First 300 words:**

I'm renaming `BillingAccount.charge` to `BillingAccount.captureFunds`. It's a billing-critical method, called from controllers, background jobs, retry queues, three test suites, and at least one webhook handler I don't remember writing. If I miss a call site, money breaks.

The default workflow is:

```bash
grep -rn "\.charge(" src/
```

312 matches. About 40 of them are real. The rest are: `recharge`, `discharge`, a `Battery.charge` field from an unrelated test, a comment from 2021 mentioning "charge the user," and a property accessor on a `Sale` model that has nothing to do with `BillingAccount`. I'm going to spend the next twenty minutes reading grep output, and at least once I'll convince myself I've handled them all and ship a regression.

There's a better way, and it's why I built `sverklo_impact`.

```
sverklo_impact BillingAccount.charge
```

Output:

```
Symbol: BillingAccount.charge (src/billing/account.ts:147)
Direct callers: 11
Transitive callers: 14
Depth: 3

[1] src/api/payments.ts:62  PaymentsController.captureCharge   (depth 1)
[2] src/jobs/retry-queue.ts:38  RetryQueue.processFailed       (depth 1)
[3] src/api/checkout.ts:91  CheckoutController.finalize        (depth 1)
...
[11] src/webhooks/stripe.ts:204  handleChargeSucceeded         (depth 1)
[12] src/api/admin.ts:55  AdminController.refund               (depth 2 ← captureCharge)
[13] src/jobs/nightly-recon.ts:18  reconcile                   (depth 2 ← processFailed)
[14] tests/integration/checkout.test.ts:412                    (depth 1)
```

Fourteen real call sites instead of 312 noisy ones. None of them contain the string `recharge`. None of them are unrelated `Battery.charge` fixtures. Each one is a function or test that will actually break if I change the symbol.

Now I can drive the rename with confidence — and I can paste this list directly into Claude Code as a checklist...

## 7. Tutorial B — "Cross-session memory for AI coding agents"

**Outline**
1. The problem: context compaction kills your decisions
2. What `sverklo_remember` actually stores — text + git SHA + file pointers
3. Bi-temporal model: decision time vs. code time
4. Recall by semantic search: `sverklo_recall retry backoff`
5. Staleness detection: when the underlying code has moved
6. Patterns that work — decision logs, "why we chose X over Y", invariants
7. Anti-patterns — don't store TODOs, don't store secrets, don't store things that belong in code comments
8. Workflow: how to teach Claude Code / Cursor to use it without prompting

**First 300 words:**

Here's the thing nobody warns you about when you start using AI coding agents on a real codebase: the agent's memory is the conversation, and the conversation gets compacted.

Yesterday, you and Claude Code spent forty minutes figuring out that `OrderProcessor` retries have to wait at least 1100ms before re-firing, because the downstream payment service has a 1-second debounce window and anything faster gets silently dropped. You ran experiments. You read logs. You wrote a test. The decision is now real, and the test enforces it, but the *reason* lives only in the conversation.

Today you open a fresh session. You ask: "why is the retry delay so long? can we drop it to 500ms?" And the agent — having lost the context — looks at the code, sees `delay: 1100`, sees no comment explaining it, and cheerfully tells you yes, you can drop it. You drop it. Production breaks at 3am.

This is the failure mode `sverklo_remember` and `sverklo_recall` exist for.

```
sverklo_remember "OrderProcessor retry delay must be ≥1100ms because the downstream payment service debounces 1s. Verified by experiment 2026-04-02. Anything faster gets silently dropped."
```

What gets stored:
- The text of the decision
- The current git SHA
- A link to the file(s) the decision is about (sverklo finds them via the same hybrid search the rest of the tools use)
- A timestamp

Tomorrow, in a fresh session, you ask: "why is the retry delay so long?" The agent runs:

```
sverklo_recall retry delay
```

It gets the decision back. It also gets a status: **still valid** (the code hasn't moved) or **stale** (the file or symbol has changed since the SHA the decision was made against). That last bit is the part I haven't seen in any other memory tool...

## 8. 90-second demo video script

**Title:** "Sverklo in 90 seconds"
**Setting:** Single terminal + Claude Code split-screen. No talking head. Calm voice. One ambient pad at -24dB or silence.

| Time | Scene (on-screen) | Voiceover |
|---|---|---|
| 0:00 – 0:05 | Black screen, white text fades in: *"Other tools remember your conversations. Sverklo understands your code."* | (silence, then) "Ninety seconds." |
| 0:05 – 0:12 | Terminal. Type: `npm install -g sverklo`. Install completes in real time (cut if >5s). | "One install. No API key, no account, no cloud." |
| 0:12 – 0:18 | Type `cd ~/code/big-typescript-repo && sverklo init`. Output scrolls: writes `.mcp.json`, updates `CLAUDE.md`, runs `sverklo doctor`, all green. | "`sverklo init` wires it into Claude Code. One command." |
| 0:18 – 0:25 | Switch to Claude Code. New session. Type the question: *"What replaced the `TokenRefresher` class I deleted last month?"* | "First question. The kind grep is bad at." |
| 0:25 – 0:38 | Claude Code calls `sverklo_search` (visible in tool-use panel). Result panel shows 6 ranked symbols. Claude responds in 2 sentences, naming the actual replacement class and file:line. | "Hybrid search — BM25, embeddings, and PageRank, fused. Six ranked symbols, not eighty grep matches. Right answer in one tool call." |
| 0:38 – 0:48 | New question: *"What's the blast radius of renaming `BillingAccount.charge`?"* Claude calls `sverklo_impact`. Output shows 14 callers, ranked, with file:line. | "Second question. `sverklo_impact` walks the call graph. Fourteen real call sites. Not three hundred grep matches polluted by `recharge` and `discharge`." |
| 0:48 – 1:02 | Type into Claude: *"Remember that retries on OrderProcessor must be ≥1100ms — downstream debounces 1s."* Claude calls `sverklo_remember`. Confirmation includes git SHA. Cut to: terminal, type `exit`. New session. Type: *"Why is the OrderProcessor retry delay so long?"* Claude calls `sverklo_recall`. Decision comes back with the SHA and a green "still valid" tag. | "Third. Memory across sessions. Pinned to the git SHA the decision was made against. Tomorrow's session knows what yesterday's session figured out — and tells you if the code has moved since." |
| 1:02 – 1:15 | Cut to README in browser, scroll to "When sverklo helps and when it doesn't" section, highlight the lists. | "Honest section in the README: sverklo isn't always the right tool. When you know exactly what string to search for, grep is fine. When you don't, you want this." |
| 1:15 – 1:25 | Cut back to terminal. Show clean install command on screen, big text:<br>`npm install -g sverklo`<br>`cd your-project && sverklo init` | "Install is one line. Local. MIT. Twenty tools. Today." |
| 1:25 – 1:30 | Final card: `sverklo.com` and `github.com/sverklo/sverklo`. Hold 5 seconds. | (silence) |

Total: 1:30. No transitions, no zoom effects, no captions other than the install command and the closing card. Real terminal output throughout — no fakes.

# 11. Reddit launch posts (per-sub, fully tailored)

**Critical rule:** never copy/paste between subs. Reddit's spam classifier flags identical first paragraphs across communities. Each below has been tailored to its sub's voice and rules.

## 11.1 r/LocalLLaMA (Wed 2026-04-15)

**Title:** Local-first code intelligence for AI coding agents — hybrid BM25 + ONNX MiniLM + PageRank, 200MB RAM, no cloud

**Body:**

I've been frustrated that every "code intelligence" tool for Claude Code / Cursor / Antigravity either ships your code to a server or relies on whatever the agent itself can grep. I wanted something that runs entirely on my laptop, doesn't ask for an API key, and actually understands the structure of a codebase instead of just doing string matching.

So I built sverklo. It's an MCP server. **Disclosure: I'm the author**, repo is github.com/sverklo/sverklo, MIT licensed.

The interesting bits, since this is r/LocalLLaMA and you'll want the receipts:

- **Embedding model:** all-MiniLM-L6-v2 via ONNX Runtime in Node. 384d vectors, ~90MB on first run, then cached at `~/.sverklo/models/`. No HF API hit after that.
- **Retrieval:** BM25 + vector cosine, fused with Reciprocal Rank Fusion, then re-ranked with PageRank computed over the file dependency graph. The intuition: structurally important files (the ones lots of other files import) should rank higher when ties are close.
- **Index:** SQLite. Indexes 38 files in ~640ms on my M2. ~200MB resident.
- **Languages:** TS, JS, Python, Go, Rust, Java, C, C++, Ruby, PHP via tree-sitter.
- **No telemetry. No network calls after the model download.** You can pull your ethernet cable and it works.

There's also a memory layer (`sverklo_remember` / `sverklo_recall`) that ties saved decisions to the git SHA they were made under, so when you `git checkout` an old branch the relevant past memories surface.

**Honest limitations**, because this sub deserves them:
- MiniLM is small and English-biased. Retrieval quality on non-English codebases or comments is meh. I want to swap in bge-small-en-v1.5 next; haven't yet.
- The dependency graph is import-level, not call-level. I can tell you which files import a file, but call-graph for dynamically dispatched calls is a TODO.
- It's not a 5x productivity miracle. It wins on exploratory questions ("what replaced this deleted code?") and refactor blast radius. It loses to plain `grep` when you already know the literal string you want.

Install:
```
npm install -g sverklo
cd your-project && sverklo init
```

Curious what you all think of the RRF-then-PageRank stack vs other approaches. Has anyone tried code-specific embeddings (CodeBERT, UniXCoder) in a real agent loop? My read is they're too heavy for the latency budget but I'd love to be wrong.

**First author comment** (post immediately):

A few things I deliberately didn't include in the post to keep it from reading like a press release, but happy to dig into:

1. Why PageRank on the file graph and not call graph — short version: the call graph is a nightmare across 10 languages and the noise/value tradeoff was bad. File-level edges are cheap and give surprising signal. I'd love to be argued out of this.
2. Why MCP and not a Cursor extension or VSCode plugin — MCP gives me one integration that works across Claude Code, Cursor, Antigravity, Windsurf, JetBrains. The cost is that the agent has to choose to call you, which puts pressure on tool descriptions.
3. The bi-temporal memory thing — I've been burned by tools that "remember" stale facts. Tying memories to git SHA means I can detect when a memory is talking about code that no longer exists.

If you find a bug, GitHub issues are fastest. If retrieval quality is bad on your codebase I really want to hear it — that's the metric I most care about.

## 11.2 r/ClaudeAI (Wed 2026-04-22, post-HN)

**Title:** I got tired of Claude Code burning tokens on grep — built a local MCP server that does semantic + dependency-graph search instead

**Body:**

If you've worked on a 50k+ LOC codebase with Claude Code you've probably watched it Grep something, get 80 matches, Read 12 of them, and still pick the wrong one. Then it tries again. That's the problem I wanted to fix without sending my code to anyone's cloud.

**Disclosure: I built this.** It's called sverklo, MIT, github.com/sverklo/sverklo.

What it actually does for Claude Code specifically:

- Adds 10 MCP tools — `sverklo_search`, `sverklo_overview`, `sverklo_lookup`, `sverklo_refs`, `sverklo_deps`, `sverklo_impact`, plus a memory layer.
- `sverklo init` writes `.mcp.json` at your project root (the only path Claude Code reads for project-scoped MCP), appends usage instructions to your `CLAUDE.md`, and runs `sverklo doctor` to verify the handshake.
- All local. ONNX MiniLM embeddings, SQLite index, ~200MB RAM, ~640ms to index a small project.
- Bi-temporal memory: `sverklo_remember` saves a decision tagged with the current git SHA so when you check out an old branch you see the decisions that were made under that state.

**The honest "when does this help" version**, because I don't want to oversell:
- **Wins:** "what replaced this deleted module", "where is auth handled", "what calls this function across the codebase". The exploratory stuff where grep gives you 200 results and you don't know which to read first.
- **Loses:** literal-string lookups, single-file diffs, anything where you already know exactly what you're looking for. Stick with Grep.

A small CLAUDE.md trick I like: I tell Claude "prefer sverklo_search over Grep when the query is conceptual." It actually respects that when the tool description is good.

Install:
```
npm install -g sverklo
cd your-project && sverklo init
# restart Claude Code, /mcp should show sverklo
```

If `/mcp` doesn't show it, run `sverklo doctor` — that command is the thing I'm proudest of, it diagnoses every common MCP setup failure (config location, binary path, handshake) and tells you what to fix.

Would love feedback on tool description wording — that's the lever that decides whether Claude actually uses sverklo or falls back to Grep, and I'm still tuning it.

**First author comment:**

Two things I want to flag for honesty:

1. v0.2.9 just shipped. There are rough edges. If `sverklo doctor` says everything is fine but `/mcp` still doesn't list it, please open an issue with the doctor output — that's gold for me.
2. There's a Pro tier coming with auto-capture of decisions and cross-project patterns, but **all 10 tools in the current release stay free MIT forever**. I'm not pulling a "free until enough people rely on it" move.

For folks asking "why not just use Claude's built-in search" — its built-in tools are Grep, Glob, Read, Bash. None of them rank by semantic similarity or know the dependency graph. That's the gap.

---

## 11.3 r/mcp (Thu 2026-04-16)

**Title:** sverklo v0.2.9 — local-first code intelligence MCP (hybrid search + impact analysis + git-tied memory)

**Body:**

New MCP server for the list. **Disclosure: author here.** MIT, github.com/sverklo/sverklo.

**What it gives an agent:**

| Tool | Purpose |
|---|---|
| `sverklo_search` | Hybrid BM25 + vector + PageRank semantic search |
| `sverklo_overview` | Codebase map ranked by structural importance |
| `sverklo_lookup` | Find function/class/type by name |
| `sverklo_refs` | All references to a symbol |
| `sverklo_deps` | File dependency graph (importers + imports) |
| `sverklo_impact` | Walk the symbol graph, score refactor blast radius |
| `sverklo_remember` / `sverklo_recall` | Cross-session memory tied to git SHA |
| `sverklo_audit` | God nodes, hub files, dead code candidates |
| `sverklo_status` | Index health |
| `sverklo_doctor` | Diagnose MCP setup issues |

**Why it might be interesting to this sub:**

- 100% local. ONNX MiniLM embeddings. No API keys, no cloud, no telemetry.
- One install works across Claude Code, Cursor, Windsurf, VS Code, JetBrains, Antigravity. `sverklo init` figures out which client is installed and writes the right config.
- Has a `doctor` command for the eternal "MCP server isn't showing up in /mcp" problem.
- Has a web dashboard (`npx sverklo ui .`) — search playground, dependency graph viewer, memory browser. Useful when you want to understand what the agent is seeing.

**Install:**
```
npm install -g sverklo
cd your-project && sverklo init
```

I'd love to hear what other MCP server authors think about tool description wording — that's the bottleneck for adoption inside an agent loop and I'm still iterating.

**First author comment:**

If you maintain a list of MCP servers, happy to add metadata however you want it. The package is `sverklo` on npm, the binary is `sverklo`, stdio transport, no auth.

One thing I learned the hard way that might help other server authors: if your tool description starts with "Use this when…" Claude Code routes to it much more reliably than if it starts with "This tool does…". Phrasing as a trigger condition rather than a description shifted my call rate noticeably.

## 11.4 r/cursor (Sun 2026-04-26)

**Title:** Cursor's @codebase vs a local MCP for big repos — when each one wins (with the boring honest version)

**Body:**

Cursor has built-in @codebase indexing and it's good. I want to talk about when it isn't enough and what I built to fill that gap, because I think it's a real and narrow thing rather than a "Cursor killer" — those posts are exhausting.

**Disclosure first:** I built sverklo, MIT, github.com/sverklo/sverklo. I use it in Cursor every day alongside @codebase, not instead of it.

**Where Cursor's built-in indexing wins for me:**
- Inline edits, tab completions, anything inside the editor frame.
- Small to medium repos.
- The first month on a new project where you don't need cross-session memory yet.

**Where I reach for sverklo:**
- 100k+ LOC monorepos where @codebase results feel diluted.
- Refactor planning — `sverklo_impact <symbol>` walks the symbol graph and tells me who actually calls a thing, with fewer false positives than text search on common names.
- Cross-session memory tied to git SHA. Cursor doesn't remember why I made a decision three weeks ago on a branch I've since merged. Sverklo does.
- When I want to know the *load-bearing* files in a package — sverklo's PageRank-ranked overview surfaces them.

**Setup in Cursor:**
```bash
npm install -g sverklo
which sverklo  # copy this path
```
Then `.cursor/mcp.json`:
```json
{
  "mcpServers": {
    "sverklo": {
      "command": "/full/path/to/sverklo",
      "args": ["."]
    }
  }
}
```
Use the full path — Cursor's spawned subprocess doesn't always inherit your shell PATH.

**Honest limits, because you'll find them anyway:**
- Sverklo doesn't do inline edits. It only feeds the agent. @codebase is still the right tool for autocomplete-adjacent stuff.
- First indexing run downloads a 90MB ONNX model. After that it's instant.
- Embeddings are MiniLM, so retrieval quality on non-English comment-heavy codebases is just okay.

I'd genuinely like to hear from anyone who's tried both — where does sverklo feel redundant with @codebase, and where does it feel additive?

**First author comment:**

Two Cursor-specific things I forgot in the post:

1. If sverklo doesn't show up in Cursor's MCP panel after restart, run `sverklo doctor` from the repo root. It tells you whether the binary, the config path, and the handshake are all healthy. Most "it's not appearing" issues are PATH issues that doctor catches.
2. Cursor's `.cursor/mcp.json` is per-project, which I prefer over Cursor's older global config approach — sverklo respects that and writes per-project on `sverklo init`.

## 11.5 r/ChatGPTCoding (Tue 2026-04-28)

**Title:** My local-first cross-agent coding stack: same code intelligence in Claude Code, Cursor, and Antigravity

**Body:**

I bounce between Claude Code, Cursor, and Google Antigravity depending on the task and I got tired of having three different mental models for "how does the agent see my codebase." I wanted one local index that all three could share.

That's what I built. **Disclosure: author here.** It's called sverklo, MIT, github.com/sverklo/sverklo.

**The setup that actually works for me:**

- One local index per project, served via MCP. ~200MB RAM, runs in the background.
- Claude Code: `sverklo init` writes `.mcp.json` and updates `CLAUDE.md`.
- Cursor: paste a 5-line block into `.cursor/mcp.json` (full binary path — Cursor's subprocess PATH is weird).
- Antigravity: writes to the global `~/.gemini/antigravity/mcp_config.json`. Antigravity has no per-project config yet, so I run separate instances under different keys per project.
- All three agents call the same 10 tools: search, overview, lookup, refs, deps, impact, plus a memory layer that's git-aware.

**Why I care about cross-agent:**
- Claude Code is best at long thoughtful refactors.
- Cursor is best at fast iterative edits in the editor.
- Antigravity is interesting for parallel agent runs.
- I don't want to re-explain my codebase to whichever one I'm using today.

**Honest "when this doesn't help":**
- If you only use one agent on small projects, this is overkill. Stick with whatever's built in.
- If you mostly do single-file edits, plain Grep beats semantic search.
- It's not magic — it's a sharper tool for exploratory and refactor-blast-radius work.

**Install once, use everywhere:**
```
npm install -g sverklo
cd your-project && sverklo init
```

Genuinely curious — for those of you using multiple agents, how are you keeping context consistent across them? Is anyone using a different shared-memory approach I should be looking at?

**First author comment:**

One thing I'll call out for the cross-agent crowd: the memory layer (`sverklo_remember`) is the part I most underestimated when I started. The fact that decisions made in Claude Code are recallable from Cursor next morning has changed how I review my own PRs. I wasn't expecting that to be the killer feature, but it might be.

If anyone has run into MCP setup pain with any of the three clients — Antigravity especially — `sverklo doctor` is the thing I built to debug that. Issues to GitHub, I'll respond same day.

## 12. Reddit response templates (paste-ready)

**Curious commenter** ("this looks neat, how do you handle X?")
> Thanks for poking. For [X specifically], it works like this: [1-2 sentence honest answer]. The trade-off I made was [trade-off] because [reason]. The thing I'd actually love feedback on is whether [specific design choice] makes sense for your kind of codebase — I built it on a TS monorepo so the heuristic might not generalize.

**Skeptic** ("why not just grep?")
> Honest answer — for a lot of queries, grep is better and I say so in the README. Sverklo wins when you don't know the literal string. Example from this morning: I asked it "what handles auth token refresh" and it surfaced two files I'd forgotten existed. Grep would've returned 30 hits on "auth" and I'd still be reading. When I do know the string ("ERR_INVALID_HANDLE"), I still run grep. They're different tools.

**Hostile** ("another AI marketing post")
> Fair suspicion — this place is drowning in launch posts. I disclosed I built it in the body. If it helps: it's MIT, all 10 tools are free forever, no telemetry, no API key step, you can run it offline. If you read the post and still think it's marketing, the repo's right there and you can judge the code instead of the framing. I'd rather you tell me it's not useful for your workflow than have you upvote it for vibes.

**Comparison** ("vs Cursor's built-in indexing?")
> I use both. Cursor's @codebase is great inside the editor and for fast inline stuff. Sverklo I reach for on big repos when I want the dependency-graph view (`sverklo_deps`) or when I need to plan a refactor and want `sverklo_impact <symbol>` to walk the symbol graph for me. They overlap maybe 30%. The non-overlapping part for me is cross-session memory tied to git SHA — Cursor doesn't remember why I made a decision two weeks ago on a since-merged branch, sverklo does. If you live entirely inside Cursor on small projects, @codebase is plenty.

**License** ("is this OSS?")
> Yes. MIT. All 10 tools in the current release are free forever. There's a planned Pro tier (auto-capture of decisions, cross-project patterns, better embedding model) but I'm being deliberate that the open-core line is "Pro adds new things, never gates current things." I've been burned by tools that quietly pulled features behind a paywall and I don't want to do that to anyone.

**Privacy** ("does it send my code anywhere?")
> No. The only network call sverklo makes is downloading the ONNX embedding model on first run (~90MB from HuggingFace), which is cached at `~/.sverklo/models/`. After that you can pull your ethernet cable and everything works — index, search, embeddings, memory, dashboard, all local. No telemetry, no analytics, no crash reports. The index lives in `~/.sverklo/<project>/index.db` on your machine. If you want to verify, the network code is in src/indexer/embedder.ts and there's exactly one fetch in there.

## 13. Reddit 14-day karma tracker — dated, checkable

Goal: by 2026-04-22, an account with **500+ comment karma**, **200+ link karma**, and recognized as a real contributor in 3–4 dev subs. **No mention of sverklo by name until launch day (2026-04-22).** Reactive disclosure if directly asked: yes. Proactive promotion: no.

**Tracker rules:**
- Mark items `[x]` as you do them. Time-box each day to 30–45 minutes.
- If you miss a day, do not "double up" the next day — that pattern looks like a content marketing playbook (because it is one). Just resume.
- "Helpful comment" means specific, useful, and 2+ sentences. One-liners like "agreed!" don't build karma and don't build trust.
- If a sub auto-removes a comment, DM the mods politely once. Do not delete-and-repost.
- **End-of-day target** is the rolling cumulative karma goal. If you're behind by day 7, slow the launch — don't fake it.

- [ ] **End of day:** 26 comments + 2 posts. Karma target ≥ 250.

**Day 7 — Wed 2026-04-15 — review + rest**

- [ ] **Stop posting today.** Reply to every reply on your day 5–6 posts.
- [ ] Open a browser tab for each tier-A sub. Read the top 50 posts of the past month. This is reconnaissance for launch positioning.
- [ ] Re-read the §11.1 r/LocalLLaMA launch draft. Note any topical references in the past 50 posts you should weave in.
- [ ] **Karma target ≥ 300.** If you're below 250, push the launch by 5 days and continue the karma plan instead of launching weak.

**Day 8 — Thu 2026-04-16 — answers, not posts**

- [ ] r/cursor: answer **5 setup questions**. Cursor users have constant MCP questions — this is the easiest karma in the entire plan.
- [ ] r/ClaudeAI: answer **3 questions** about Claude Code MCP setup.
- [ ] r/mcp: answer any open question.
- [ ] **End of day:** 35 comments + 2 posts. Karma target ≥ 360.

**Day 9 — Fri 2026-04-17 — value post #2**

- [ ] r/devtools: post **"How I evaluate dev tools before installing them"** — a checklist. No product. No CTA. Pure framework. This anchors you as a discerning user, not a marketer.
- [ ] r/opensource: comment on **2 license/governance threads** with substance.
- [ ] **End of day:** 37 comments + 3 posts. Karma target ≥ 420.

**Day 10 — Sat 2026-04-18 — final lurk + draft review**

- [ ] **Read the full §11.1–11.5 launch posts in this file again.** Out loud if possible. Anything that sounds like marketing copy gets cut.
- [ ] Have a friend who is *not* a dev marketer read each one. If they say "this sounds like an ad," rewrite it.
- [ ] r/LocalLLaMA: comment on **2 threads** to stay visible in the sub before launch.
- [ ] **End of day:** 39 comments + 3 posts. Karma target ≥ 460.

**Day 11 — Sun 2026-04-19 — competitor scan**

- [ ] Search every tier-A sub for "Cursor indexing", "Claude Context", "code search", "MCP server" in the past 7 days.
- [ ] If a competitor (Sourcegraph, Continue, Aider, Greptile, code-review-graph) launched something this week — **push your launch by 5 days**. Don't fight someone else's wave.
- [ ] If clear: confirm the Show HN draft (§2) and HN account is ready. Test the HN account by upvoting 3 unrelated submissions.
- [ ] r/ChatGPTCoding: answer **3 questions**.
- [ ] **End of day:** 42 comments. Karma target ≥ 500.

**Day 12 — Mon 2026-04-20 — pre-launch ammunition check**

- [ ] **Stress test sverklo.com.** Open 20 tabs simultaneously. Make sure CDN is healthy.
- [ ] Verify GitHub repo: README renders, FIRST_RUN.md links work, badges are not 404, 20 topics are set.
- [ ] Verify npm: `npm install -g sverklo@latest` on a fresh machine, run `sverklo init` end-to-end, confirm `sverklo doctor` passes.
- [ ] Pre-write 10 GitHub issue templates for the issues you expect on launch day (config path on Windows, ONNX download fails, MCP not appearing in /mcp, etc.). Drafts in `~/Desktop/sverklo-launch-day-replies.md`.
- [ ] **No Reddit posting today.** Comment only if directly @-ed.

**Day 13 — Tue 2026-04-21 — Show HN day**

- [ ] **08:00 ET — submit Show HN.** Title from §2. Submit from your HN account.
- [ ] **08:01 ET — drop the first author comment from §2** as the very first reply on your own submission. This matters more than the title.
- [ ] **08:00 → 20:00 ET — live in the HN comments for 12 hours.** Reply to every comment within 30 minutes. Comment velocity is part of HN's ranking signal — this is non-negotiable.
- [ ] When asked "is this on Reddit yet?" → say "tomorrow." Do not cross-post.
- [ ] Publish the launch blog post (§1) and X launch thread (§3) and LinkedIn post (§4) the same morning. dev.to crosspost too. **Not** any Reddit posts today.
- [ ] **No Reddit launch today.** Reddit comes tomorrow with HN social proof.

**Day 14 — Wed 2026-04-22 — Reddit launch day**

- [ ] **09:00 PT — r/LocalLLaMA post** from §11.1. Drop the first author comment immediately.
- [ ] **Stay glued to r/LocalLLaMA comments for 6 hours.** Reply to every commenter within 30 minutes.
- [ ] **No other subs today.** Do not post r/mcp, r/ClaudeAI, r/cursor, or r/ChatGPTCoding today. Reddit's spam classifier flags multi-sub launches in the same 24h window.
- [ ] Publish "What I got wrong yesterday — answers to top 5 HN comments" X reply thread.

## 13a. Post-launch Reddit cadence (Day 15+)

**Day 15 — Thu 2026-04-23**
- [ ] r/mcp: post §11.3. Different angle from r/LocalLLaMA.

**Day 16 — Fri 2026-04-24**
- [ ] Reply day. No new posts. Catch up on r/LocalLLaMA + r/mcp comment threads from days 14–15.

**Day 17 — Sat 2026-04-25**
- [ ] Comment-only on r/ClaudeAI, r/cursor — be visible without posting.

**Day 18 — Sun 2026-04-26**
- [ ] **10:00 ET — r/cursor post** from §11.4. Sun PM ET = peak Cursor sub traffic. Different angle: vs @codebase.

**Day 19 — Mon 2026-04-27**
- [ ] r/ClaudeAI launch post from §11.2. Different angle: token-burn pain.
- [ ] Stay in comments 6h.

**Day 20 — Tue 2026-04-28**
- [ ] r/ChatGPTCoding launch post from §11.5. Different angle: cross-agent stack.
- [ ] **All five tier-A subs are now done.** Pause Reddit posting for 7 days. Comment-only.

**Day 21–28 — recovery week**
- [ ] Reply to every active thread on every sub once a day.
- [ ] Tier B sequence: r/devtools (Day 22), r/opensource (Day 24), r/coolgithubprojects (Day 26), r/commandline (Day 28).
- [ ] **No posts to r/programming until Day 30+** — and only as a link post to a real technical blog deep-dive, never as "Show".
- [ ] **No posts to r/MachineLearning until you have eval methodology vs grep/aider repo-map**, and only as `[P]` with that methodology front and center.

**Hard rule:** if anyone asks you directly "what are you working on?", you may answer truthfully and link the repo with disclosure. Reactive disclosure is fine. Proactive is not.

## 14. Reddit red flags (NEVER do these)

1. **Never post a launch in r/ExperiencedDevs.** Their rules treat tool promotion as bannable. Reactive comments only with disclosure.
2. **Never post a "Show HN-style" self-post in r/programming.** That sub punishes "I built X" framing. Only path in: a deep technical link post to a blog, with the repo mentioned in the body, not the title. Verify their 9:1 self-promo ratio rule first.
3. **Never use "revolutionary", "game-changer", "AI-powered", "the future of coding", or any emoji in titles.** AutoMod on multiple dev subs silently removes. r/MachineLearning specifically nukes any `[P]` post that reads as marketing.
4. **Never use Reddit's cross-post button.** It marks the post visibly as a crosspost and drops engagement to near-zero. Always rewrite from scratch per sub.
5. **Never run `sverklo init` in a video demo on a repo with secrets.** Someone will pause the frame.

## 15. AMA pitches (W4–6 post-launch)

**r/LocalLLaMA modmail template:**
> Hey, the post on sverklo did well last week. I'd love to do a follow-up technical deep-dive thread focused on the retrieval stack — RRF fusion, PageRank on code graphs, eval methodology — and answer questions for a day. Would that be welcome or would you prefer I just post it normally?

**r/mcp:** "MCP server author Q&A — happy to do a Q&A on what I learned building an MCP server that ships to multiple clients (Claude Code, Cursor, Antigravity), including the parts that broke."

**r/ClaudeAI modmail:** "I built an MCP server people in this sub have started using, would you be open to an official tool-author Q&A thread with the [Tool Author] flair?"

Always ask. Never assume. Don't pitch r/programming, r/ML, r/ExperiencedDevs, r/cursor for AMAs — wrong culture.
