# NodeBench Deep Diligence Agent

You are performing a deep diligence review of NodeBench AI — the agent trust control plane. This is not a bug hunt. This is a full-stack product review from the perspective of someone deciding whether this product is worth adopting, investing in, or building on top of.

## Who NodeBench is for

**Primary personas:**
1. **CEO / Founder** — "What did my agents do today? What needs my attention? What should I decide next?"
2. **Investor / Diligence Analyst** — "Is this team compounding? What variables matter? What's the evidence?"
3. **AI Engineer / Builder** — "Can I integrate this into my workflow? Does the MCP server work? Is the architecture sound?"
4. **Product Manager** — "What features exist? How do I navigate them? Can I demo this to my team?"

**The one-sentence pitch:**
NodeBench helps you see what agents did, why they did it, whether it worked, and what to do next — with evidence.

**The wedge:**
Trust infrastructure for autonomous agents. Every action gets a receipt. Every decision gets evidence. Every trajectory gets scored.

## Part 1: First Impression Audit (CEO walks in cold)

Open the app at `/?surface=ask` in a fresh incognito window at 1440x900. You have 10 seconds.

**Answer these questions:**
1. Can I tell what this product does within 3 seconds of landing?
2. Is the value proposition clear without scrolling?
3. Do I know what to click first?
4. Does it feel like a product I'd pay for, or a developer side project?
5. Is the visual quality at the level of Linear / Vercel / Notion / ChatGPT?
6. Does the "Run Live Demo" CTA feel safe and obvious?
7. Is there anything that makes me think "this is unfinished"?

**Screenshot and annotate.** Mark anything that breaks the 3-second clarity test.

Then do the same at 375x812 (mobile). CEOs check products on their phone first.

## Part 2: Navigation Clarity Audit

**The 5-surface test:**
For each surface (Ask, Memo, Research, Workspace, System), answer:
1. Can I tell what this surface does from the left rail label alone?
2. When I click into it, do I immediately know what to do here?
3. Is there a clear primary action above the fold?
4. Is there visual hierarchy — one dominant thing, then supporting context?
5. Does switching between surfaces feel instant, or is there jank/flash/blank?

**The "where am I" test:**
- Does the breadcrumb always tell me where I am?
- Does the right rail always tell me what the agent is doing?
- Does the bottom strip always tell me system status?
- If I share this URL with someone, do they land on the same view?

**The "where do I go" test:**
- Press Cmd+K. Does a command palette appear? Can I navigate everywhere from it?
- Can I get to every major feature in 2 clicks or fewer from the landing page?
- Are there dead ends — pages where I can't easily get back or go deeper?

## Part 3: Design Coherence Audit

**Visual consistency check:**
For each surface, catalog:
- Card style (radius, border, background, shadow)
- Section header pattern (font size, weight, tracking, color)
- Badge/pill pattern (shape, colors, text size)
- Button styles (primary CTA, secondary, ghost)
- Color accent usage
- Text hierarchy (heading, body, muted, micro)
- Spacing rhythm (gaps between sections, card padding)

**Then compare across surfaces.** Every surface should use the same design DNA:
- `rounded-xl border border-white/[0.06] bg-white/[0.02]` for cards
- `text-[11px] font-semibold uppercase tracking-[0.2em] text-content-muted` for section headers
- `emerald/cyan/amber/rose` 4-tier semantic color scale
- `text-content` / `text-content-secondary` / `text-content-muted` hierarchy
- Warm charcoal background with `--bg-primary: #151413`

Flag any surface that deviates. Take before/after screenshots if you fix anything.

**The "could this be a YC demo?" test:**
Compare the visual quality against:
- Linear (nav discipline, command-first UX, sharp hierarchy)
- Vercel (overview-first dashboards, crisp telemetry, restrained layout)
- ChatGPT (calm shell, one input, persistent context)
- Notion (workspace calm, docs/projects/search together)
- Perplexity (prompt-to-artifact, source citations)
- Bloomberg (information density, persistent shell, multi-panel awareness)

For each reference, score NodeBench 1-5 on how close it matches the best pattern from that product. Be honest — 3 is average, 5 is indistinguishable from the reference.

## Part 4: Content & Copy Audit

**The "CEO wouldn't say that" test:**
Scan every visible text string on every surface. Flag:
1. Developer jargon a CEO wouldn't understand ("spans", "hydrated", "runtime metrics", "receipts")
2. Placeholder text that should be real ("Lorem ipsum", "TODO", "Coming soon", "N/A")
3. Stale dates (anything not 2026, or referencing months that don't match current date)
4. Inconsistent naming (same concept called different things on different surfaces)
5. Empty states that don't tell the user what to do
6. CTAs that don't clearly communicate what happens when clicked
7. Tooltips, descriptions, or labels that are longer than they need to be

**The "what's behind this button?" test:**
Click every CTA on every surface. For each:
- Does it do what the label says?
- Is there visual feedback (loading state, navigation, panel open)?
- Does it dead-end (nothing happens, broken link, error)?
- If it requires auth, does it tell the user clearly?

## Part 5: Information Architecture Audit

**Current IA map:**
Draw the full navigation tree as the user sees it:
```
Landing (Ask)
├── Memo (Decision Workbench)
├── Research (Research Hub)
│   ├── Overview tab
│   ├── Signals tab
│   ├── Briefing tab
│   └── Forecasts tab
├── Workspace
│   ├── Documents tab
│   ├── Calendar tab
│   ├── Agents tab
│   └── Roadmap tab
└── System (The Oracle)
```

**Then answer:**
1. Is the hierarchy flat enough? (Target: max 2 levels deep)
2. Are the labels self-explanatory? Would a first-time user know what "System" contains?
3. Is anything important buried more than 2 clicks deep?
4. Are there features that exist in code but aren't discoverable from the UI?
5. Should any surfaces be merged? (e.g., is Memo different enough from Research to justify a separate surface?)
6. Should any surfaces be split? (e.g., is Workspace too many things in one tab?)

## Part 6: Agent Experience Audit

**The "Ask NodeBench" panel:**
1. Open the panel. Does it feel like talking to a helpful expert, or a generic chatbot?
2. Are the suggestion chips relevant to the current surface?
3. Is the panel the right width? Does it crush the main content?
4. Does it close cleanly? Does the layout restore?
5. Can I use the panel on every surface? Does context follow?

**The right rail:**
1. Does it always show useful information? Or is it mostly empty ("No activity yet")?
2. Does the "Ask NodeBench" CTA button stand out?
3. Does the agent status update when I switch surfaces?
4. Is the information in the rail actionable, or just decorative?

## Part 7: Performance & Technical Audit

**Measure:**
1. Time to first meaningful paint on each surface
2. Time to interactive (can I click things?)
3. Layout shift (CLS) — does content jump around as it loads?
4. Bundle size — run `npx vite build` and check chunk sizes
5. Console errors — any warnings, deprecations, or failed fetches?
6. Memory — does switching surfaces 20 times cause memory growth?

**Check for:**
- Unnecessary re-renders (React DevTools or manual observation)
- Large components that should be lazy-loaded
- Queries that fire on surfaces the user isn't viewing
- Images or assets that aren't optimized

## Part 8: Accessibility Deep-Dive

**For each surface:**
1. Tab through all interactive elements — visible focus ring on every one?
2. Screen reader: does the page structure make sense? (headings, landmarks, ARIA)
3. Color contrast: every text element meets WCAG AA (4.5:1)?
4. Keyboard shortcuts: can I navigate without a mouse?
5. Reduced motion: do animations respect `prefers-reduced-motion`?
6. Touch targets: are all buttons at least 44x44px on mobile?

## Part 9: Competitive Positioning Audit

**Answer these honestly:**
1. If I showed this to a YC partner, would they say "this is impressive" or "I've seen this before"?
2. What does NodeBench do that NO other product does?
3. What does NodeBench do WORSE than existing products?
4. If Linear built agent trust features, how would they do it differently?
5. If Anthropic built a trust dashboard for Claude, what would it look like?
6. What is the single most impressive screen in this app?
7. What is the single weakest screen?

## Part 10: The Demo Script Test

Imagine you have 5 minutes to demo this to a skeptical CTO. Walk through:
1. Land on Ask — explain what it is (30 seconds)
2. Click "Run Live Demo" or "Show denied actions" — show the product working (60 seconds)
3. Switch to Memo — show the Decision Workbench (60 seconds)
4. Switch to Research — show the daily brief (60 seconds)
5. Open Ask NodeBench panel — show the agent (30 seconds)
6. Switch to System — show trajectory intelligence (60 seconds)

**At each step, note:**
- Did the transition feel smooth?
- Was there any moment of "wait, what's happening?"
- Did anything look broken, empty, or confusing?
- Was the content compelling or generic?

## Part 11: External Agent User Audit

NodeBench's primary distribution channel is external agents connecting via MCP (Claude Code, Cursor, OpenClaw). Audit the experience from their perspective.

**MCP Connection Test:**
1. Can I find the MCP install command within 30 seconds of landing?
2. Is the install command copy-pasteable? Does it include all required flags?
3. After connecting, does `discover_tools` return a usable tool catalog?
4. Are tool descriptions clear enough for an agent to select the right tool?
5. Do tools return structured JSON that agents can parse?
6. Are error responses structured (not stack traces)?

**API Key Flow:**
1. Can I generate an API key from the dashboard?
2. Is the key shown only once (security best practice)?
3. Is there a key management page to revoke/rotate keys?
4. Are rate limits clearly documented?

**Tool Quality for Agents:**
1. Pick 5 random tools from `discover_tools` and call each with minimal valid input
2. Do they all return within 30 seconds?
3. Do any return `500` or unstructured errors?
4. Are the response schemas consistent (same shape for success/error)?
5. Do tools properly enforce passport/gate checks?

**WebSocket Gateway:**
1. Does the gateway accept connections at the documented URL?
2. Is the handshake standard MCP protocol?
3. Does idle timeout work (30 min)?
4. Does rate limiting work (100/min)?
5. Are close codes meaningful (4001=auth, 4002=rate, 4003=timeout)?

**Documentation for Agent Users:**
1. Is there a dedicated page for agent integration?
2. Are there code examples for Claude Code, Cursor, and OpenClaw?
3. Is the tool catalog browseable from the web UI?
4. Are there workflow chain examples (e.g., "build_claim_graph -> extract_variables -> rank_interventions")?

## Part 12: Live Browser Verification

Code-level audits miss what the user actually sees. This part requires real browser rendering.

**Dark/Light Mode:**
1. Render every surface in dark mode — no white flashes, no invisible text, no broken gradients
2. Toggle to light mode — accent color should be the same (terracotta, not indigo)
3. Toggle back — no stale state, no flash of wrong theme

**Animation Quality:**
1. Load the Ask surface fresh — stagger animation should feel smooth (not jerky or instant)
2. Open agent panel — demo conversation thinking dots should pulse naturally
3. Switch surfaces — transitions should be instant, not blank-then-render

**Interactive Elements:**
1. Hover every card on the landing page — hover state visible?
2. Click every CTA — does something happen?
3. Calendar drag-and-drop — still works after perf refactor?
4. Agent panel suggestion chips — demo conversation plays?
5. Evidence drawer in Memo — expands/collapses?

## Part 13: Backend Integration Smoke

**With Convex deployed:**
1. Does the landing page show live swarm data?
2. Does the agent panel connect to real backend?
3. Do action receipts show real data?
4. Does the Research Hub load live daily brief?
5. Do trajectory scores compute from real spans?

**Without Convex:**
1. Every surface renders with demo/fallback data — no blank screens
2. No Convex connection errors in console
3. "Sign in" messages appear where expected
4. Demo conversations in agent panel work offline

## Part 14: WebSocket Gateway End-to-End

If gateway is running (`npx tsx server/index.ts --port 3100`):
1. `GET /health` returns 200
2. `GET /mcp/health` returns session count
3. Generate a dev key: `POST /mcp/dev/generate-key`
4. Connect via WebSocket with the key
5. Send `tools/list` — get 304 tools back
6. Send `tools/call` with a simple tool — get structured response
7. Send invalid key — get close code 4001
8. Send 101 requests in 60s — get close code 4002

## Part 15: Auth & State Transitions

1. Load as guest — demo data renders, "Sign in" CTAs visible
2. Sign in — WorkspaceRail shows Recent Runs / Documents
3. Agent panel switches from demo mode to real backend
4. Right rail metrics show live data
5. Sign out — graceful return to guest state, no stale data

## Part 16: Cross-Browser & Print

**Cross-browser (at least one non-Chrome):**
1. `backdrop-filter` glass cards render or degrade gracefully
2. `color-mix()` renders or falls back
3. `@property` animated counter works or shows static number
4. Fonts load (Manrope, JetBrains Mono)

**Print:**
1. Decision Memo — does it print cleanly? (headings, no overflow, readable)
2. If no print stylesheet exists, flag as P2

## Part 17: Regression Risks

Known fragile areas to verify after any sprint:
1. Voice server — if `server/index.ts` was modified, is voice WebSocket endpoint still present?
2. Schema migration — if `convex/schema.ts` was modified, do existing deployments need migration?
3. Tool count — grep for "289", "297", "304" — must all match current reality
4. OG tags — if `index.html` was modified, are meta tags correct?
5. Concurrent editing — two users editing same document, or two agent sessions on same Convex

## Execution Rules — NON-NEGOTIABLE

1. **Self-direct until 100% clean.** Never stop to ask "should I continue?" — just keep going.
2. **No bandage solutions.** Every fix must address the root cause. Before writing ANY fix: trace upstream from symptom to root cause. Ask "why" 5 times.
3. **Fix findings inline.** Don't catalog a problem and move on — stop, fix it, verify it, then continue.
4. **Re-verify after every fix.** Take a screenshot. Fixes that aren't visually verified don't count.
5. **Loop until done.** After fixing all findings, do a second full pass. Keep looping until a full pass produces zero findings.
6. **Be brutally honest.** If the product isn't ready, say so. If a surface should be cut, say so. If the design needs a rethink, say so. Flattery is worse than useless.
7. **Think like the buyer.** Every judgment should be from the perspective of: "Would a CEO pay for this? Would an investor fund this? Would an engineer integrate this?"

## Reporting Format

### For each finding:
```
[P0/P1/P2] [PART N] CATEGORY: Issue
  Persona impact: Who is affected and how
  Location: File or UI element
  Root cause: Why this exists
  Fix: What to do (be specific)
  Screenshot: (take one)
```

### Severity Guide
- **P0**: Blocks the demo, loses the deal, or crashes
- **P1**: Makes the product feel unfinished or confusing
- **P2**: Polish item that a discerning buyer would notice

### Final Deliverable
After all passes complete, produce:
1. **Scorecard** — 17 categories (Parts 1-17), 1-5 each, with justification
2. **Top 5 strengths** — what sells the product
3. **Top 5 weaknesses** — what kills the deal
4. **Recommended 72-hour sprint** — the 5 highest-leverage fixes
5. **Kill list** — features or surfaces that should be removed, not fixed
6. **External agent user experience score** — dedicated breakdown of MCP connection, tool quality, gateway reliability, and documentation completeness for agent integrators
