# Hindsight Retain Alignment Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Align auto-retain/recall with Hindsight best practices — `document_id` + append mode, chat tags, structured JSON content, recall query truncation.

**Architecture:** Extend `HindsightClient` in the core library with new optional parameters (`document_id`, `update_mode`, `tags`, `tags_match`). Update the bot's auto-retain in `worker.rs` to use structured JSON content with session-level `document_id` and chat tags. Update the aggregator's MCP tool calls to pass `None` for the new params. Cron retain is unchanged (different use case — summary text, no session).

**Tech Stack:** Rust, serde, reqwest, tokio, chrono (for UTC timestamps)

### Task 1: Add `document_id`, `update_mode`, `tags` to `RetainItem` and update `retain()` signature

**Files:**
- Modify: `crates/rightclaw/src/memory/hindsight.rs:57-71` (RetainItem, RetainRequest structs)
- Modify: `crates/rightclaw/src/memory/hindsight.rs:130-166` (retain method)
- Test: `crates/rightclaw/src/memory/hindsight.rs` (existing test module)

- [ ] **Step 1: Write failing test for retain with document_id + update_mode + tags**

Add this test after the existing `retain_without_context` test (~line 361) in `crates/rightclaw/src/memory/hindsight.rs`:

```rust
#[tokio::test]
async fn retain_with_document_id_and_tags() {
    let (handle, url) = mock_hindsight_server(
        r#"{"success": true, "operation_id": "op-456"}"#,
        200,
    )
    .await;

    let client = test_client(&url);
    let tags = vec!["chat:12345".to_string()];
    let resp = client
        .retain(
            "User: hello\nAssistant: hi",
            Some("conversation between RightClaw Agent and the User"),
            Some("session-uuid-abc"),
            Some("append"),
            Some(&tags),
        )
        .await
        .unwrap();

    assert!(resp.success);

    let (_method, _auth, body) = handle.await.unwrap();
    let parsed: serde_json::Value = serde_json::from_str(&body).unwrap();
    assert_eq!(parsed["items"][0]["document_id"], "session-uuid-abc");
    assert_eq!(parsed["items"][0]["update_mode"], "append");
    assert_eq!(parsed["items"][0]["tags"][0], "chat:12345");
    assert_eq!(
        parsed["items"][0]["context"],
        "conversation between RightClaw Agent and the User"
    );
}
```

- [ ] **Step 2: Write failing test for retain without optional fields (backward compat)**

Add this test right after the previous one:

```rust
#[tokio::test]
async fn retain_without_document_id_omits_fields() {
    let (handle, url) = mock_hindsight_server(
        r#"{"success": true}"#,
        200,
    )
    .await;

    let client = test_client(&url);
    client.retain("a fact", None, None, None, None).await.unwrap();

    let (_method, _auth, body) = handle.await.unwrap();
    let parsed: serde_json::Value = serde_json::from_str(&body).unwrap();
    assert!(parsed["items"][0].get("document_id").is_none());
    assert!(parsed["items"][0].get("update_mode").is_none());
    assert!(parsed["items"][0].get("tags").is_none());
    assert!(parsed["items"][0].get("context").is_none());
}
```

- [ ] **Step 3: Run tests to verify they fail**

Run: `devenv shell -- cargo test -p rightclaw retain -- --nocapture 2>&1 | tail -20`
Expected: compilation errors — `retain()` takes 2 args, not 5

- [ ] **Step 4: Update `RetainItem` struct with new optional fields**

In `crates/rightclaw/src/memory/hindsight.rs`, replace the `RetainItem` struct (~lines 57-63):

```rust
/// Retain request item.
#[derive(Debug, Serialize)]
struct RetainItem {
    content: String,
    #[serde(skip_serializing_if = "Option::is_none")]
    context: Option<String>,
    #[serde(skip_serializing_if = "Option::is_none")]
    document_id: Option<String>,
    #[serde(skip_serializing_if = "Option::is_none")]
    update_mode: Option<String>,
    #[serde(skip_serializing_if = "Option::is_none")]
    tags: Option<Vec<String>>,
}
```

- [ ] **Step 5: Update `retain()` method signature and body**

Replace the `retain` method (~lines 130-166):

```rust
/// Store content in the memory bank.
pub async fn retain(
    &self,
    content: &str,
    context: Option<&str>,
    document_id: Option<&str>,
    update_mode: Option<&str>,
    tags: Option<&[String]>,
) -> Result<RetainResponse, MemoryError> {
    let url = format!(
        "{}/v1/default/banks/{}/memories",
        self.base_url, self.bank_id
    );
    let body = RetainRequest {
        items: vec![RetainItem {
            content: content.to_owned(),
            context: context.map(|s| s.to_owned()),
            document_id: document_id.map(|s| s.to_owned()),
            update_mode: update_mode.map(|s| s.to_owned()),
            tags: tags.map(|t| t.to_vec()),
        }],
        is_async: true,
    };

    let resp = self
        .http
        .post(&url)
        .header("Authorization", format!("Bearer {}", self.api_key))
        .json(&body)
        .timeout(RETAIN_TIMEOUT)
        .send()
        .await
        .map_err(|e| MemoryError::HindsightRequest(format!("{e:#}")))?;

    let status = resp.status().as_u16();
    if !resp.status().is_success() {
        let body = resp.text().await.unwrap_or_default();
        return Err(MemoryError::Hindsight { status, body });
    }

    resp.json::<RetainResponse>()
        .await
        .map_err(|e| MemoryError::HindsightRequest(format!("parse retain response: {e:#}")))
}
```

- [ ] **Step 6: Fix existing retain tests to pass new params**

Update `retain_sends_correct_request` (~line 328-329):
```rust
let resp = client
    .retain("user likes dark mode", Some("preference setting"), None, None, None)
    .await
    .unwrap();
```

Update `retain_without_context` (~line 356):
```rust
client.retain("some fact", None, None, None, None).await.unwrap();
```

Update `retain_http_error_returns_error` (~line 372):
```rust
let err = client.retain("test", None, None, None, None).await.unwrap_err();
```

- [ ] **Step 7: Run tests to verify they pass**

Run: `devenv shell -- cargo test -p rightclaw retain -- --nocapture 2>&1 | tail -20`
Expected: all retain tests pass (5 tests)

- [ ] **Step 8: Commit**

```bash
git add crates/rightclaw/src/memory/hindsight.rs
git commit -m "feat(hindsight): add document_id, update_mode, tags to retain API"
```

### Task 2: Add `tags` and `tags_match` to `QueryRequest` and update `recall()` signature

**Files:**
- Modify: `crates/rightclaw/src/memory/hindsight.rs:73-79` (QueryRequest struct)
- Modify: `crates/rightclaw/src/memory/hindsight.rs:168-201` (recall method)
- Test: `crates/rightclaw/src/memory/hindsight.rs` (existing test module)

- [ ] **Step 1: Write failing test for recall with tags**

Add this test after the existing `recall_empty_results` test in `crates/rightclaw/src/memory/hindsight.rs`:

```rust
#[tokio::test]
async fn recall_with_tags() {
    let (handle, url) = mock_hindsight_server(
        r#"{"results": [{"text": "user likes dark mode", "score": 0.9}]}"#,
        200,
    )
    .await;

    let client = test_client(&url);
    let tags = vec!["chat:12345".to_string()];
    let results = client
        .recall("preferences", Some(&tags), Some("any"))
        .await
        .unwrap();

    assert_eq!(results.len(), 1);

    let (_method, _auth, body) = handle.await.unwrap();
    let parsed: serde_json::Value = serde_json::from_str(&body).unwrap();
    assert_eq!(parsed["tags"][0], "chat:12345");
    assert_eq!(parsed["tags_match"], "any");
}
```

- [ ] **Step 2: Write failing test for recall without tags (backward compat)**

```rust
#[tokio::test]
async fn recall_without_tags_omits_fields() {
    let (handle, url) = mock_hindsight_server(
        r#"{"results": []}"#,
        200,
    )
    .await;

    let client = test_client(&url);
    client.recall("test query", None, None).await.unwrap();

    let (_method, _auth, body) = handle.await.unwrap();
    let parsed: serde_json::Value = serde_json::from_str(&body).unwrap();
    assert!(parsed.get("tags").is_none());
    assert!(parsed.get("tags_match").is_none());
}
```

- [ ] **Step 3: Run tests to verify they fail**

Run: `devenv shell -- cargo test -p rightclaw recall -- --nocapture 2>&1 | tail -20`
Expected: compilation errors — `recall()` takes 1 arg, not 3

- [ ] **Step 4: Update `QueryRequest` struct with optional tags fields**

Replace the `QueryRequest` struct (~lines 73-79):

```rust
/// Request body shared by recall and reflect endpoints.
#[derive(Debug, Serialize)]
struct QueryRequest {
    query: String,
    budget: String,
    max_tokens: u32,
    #[serde(skip_serializing_if = "Option::is_none")]
    tags: Option<Vec<String>>,
    #[serde(skip_serializing_if = "Option::is_none")]
    tags_match: Option<String>,
}
```

- [ ] **Step 5: Update `recall()` method signature and body**

Replace the `recall` method (~lines 168-201):

```rust
/// Recall memories relevant to a query.
pub async fn recall(
    &self,
    query: &str,
    tags: Option<&[String]>,
    tags_match: Option<&str>,
) -> Result<Vec<RecallResult>, MemoryError> {
    let url = format!(
        "{}/v1/default/banks/{}/memories/recall",
        self.base_url, self.bank_id
    );
    let body = QueryRequest {
        query: query.to_owned(),
        budget: self.budget.clone(),
        max_tokens: self.max_tokens,
        tags: tags.map(|t| t.to_vec()),
        tags_match: tags_match.map(|s| s.to_owned()),
    };

    let resp = self
        .http
        .post(&url)
        .header("Authorization", format!("Bearer {}", self.api_key))
        .json(&body)
        .timeout(RECALL_TIMEOUT)
        .send()
        .await
        .map_err(|e| MemoryError::HindsightRequest(format!("{e:#}")))?;

    let status = resp.status().as_u16();
    if !resp.status().is_success() {
        let body = resp.text().await.unwrap_or_default();
        return Err(MemoryError::Hindsight { status, body });
    }

    let response: RecallResponse = resp
        .json()
        .await
        .map_err(|e| MemoryError::HindsightRequest(format!("parse recall response: {e:#}")))?;
    Ok(response.results)
}
```

- [ ] **Step 6: Update `reflect()` to pass None for new QueryRequest fields**

The `reflect()` method also uses `QueryRequest`. Update its body construction (~line 209):

```rust
let body = QueryRequest {
    query: query.to_owned(),
    budget: self.budget.clone(),
    max_tokens: self.max_tokens,
    tags: None,
    tags_match: None,
};
```

- [ ] **Step 7: Fix existing recall tests to pass new params**

Update `recall_sends_correct_request` (~line 391):
```rust
let results = client.recall("what does user prefer", None, None).await.unwrap();
```

Update `recall_empty_results` (~line 418):
```rust
let results = client.recall("nonexistent topic", None, None).await.unwrap();
```

- [ ] **Step 8: Run tests to verify they pass**

Run: `devenv shell -- cargo test -p rightclaw -- --nocapture 2>&1 | tail -30`
Expected: all tests pass (retain, recall, reflect, bank tests)

- [ ] **Step 9: Commit**

```bash
git add crates/rightclaw/src/memory/hindsight.rs
git commit -m "feat(hindsight): add tags and tags_match to recall API"
```

### Task 3: Update aggregator and cron retain/recall call sites

**Files:**
- Modify: `crates/rightclaw-cli/src/aggregator.rs:182-228` (HindsightBackend::tools_call)
- Modify: `crates/bot/src/cron.rs:564` (cron auto-retain)

- [ ] **Step 1: Update aggregator `memory_retain` call**

In `crates/rightclaw-cli/src/aggregator.rs`, update the `memory_retain` arm (~line 189):

```rust
let result = self
    .client
    .retain(content, context, None, None, None)
    .await
    .map_err(|e| anyhow::anyhow!("{e:#}"))?;
```

- [ ] **Step 2: Update aggregator `memory_recall` call**

In the same file, update the `memory_recall` arm (~line 206):

```rust
let results = self
    .client
    .recall(query, None, None)
    .await
    .map_err(|e| anyhow::anyhow!("{e:#}"))?;
```

- [ ] **Step 3: Update cron auto-retain call**

In `crates/bot/src/cron.rs`, update the retain call (~line 564):

```rust
if let Err(e) = hs_retain.retain(&summary, Some(&context), None, None, None).await {
```

- [ ] **Step 4: Verify workspace compiles**

Run: `devenv shell -- cargo build --workspace 2>&1 | tail -20`
Expected: clean build, no errors

- [ ] **Step 5: Run full test suite**

Run: `devenv shell -- cargo test --workspace 2>&1 | tail -30`
Expected: all tests pass

- [ ] **Step 6: Commit**

```bash
git add crates/rightclaw-cli/src/aggregator.rs crates/bot/src/cron.rs
git commit -m "fix: update retain/recall call sites for new signatures"
```

### Task 4: Update worker auto-retain — structured JSON content, document_id, tags, context

**Files:**
- Modify: `crates/bot/src/telegram/worker.rs:518-533` (auto-retain block)
- Modify: `crates/bot/src/telegram/worker.rs:694-710` (session UUID capture)

- [ ] **Step 1: Capture `session_uuid` from session lookup for later use in retain**

In `crates/bot/src/telegram/worker.rs`, the session lookup at ~line 694 produces `cmd_args` containing the UUID. Extract the UUID into a separate variable. Replace lines ~694-710:

```rust
// Session lookup / create (SES-02, SES-03)
let (cmd_args, is_first_call, session_uuid) = match get_active_session(&conn, chat_id, eff_thread_id) {
    Ok(Some(SessionRow { root_session_id, .. })) => {
        // Resume: --resume <root_session_id>
        let uuid = root_session_id.clone();
        (vec!["--resume".to_string(), root_session_id], false, uuid)
    }
    Ok(None) => {
        // First message: generate UUID, --session-id <uuid>
        let new_uuid = Uuid::new_v4().to_string();
        let label = first_text.map(truncate_label);
        create_session(&conn, chat_id, eff_thread_id, &new_uuid, label)
            .map_err(|e| format!("⚠️ Agent error: session create failed: {:#}", e))?;
        let uuid = new_uuid.clone();
        (vec!["--session-id".to_string(), new_uuid], true, uuid)
    }
    Err(e) => {
        return Err(format!("⚠️ Agent error: session lookup failed: {:#}", e));
    }
};
```

- [ ] **Step 2: Update auto-retain block with structured JSON, document_id, tags**

Replace the auto-retain block at ~lines 518-533:

```rust
// Auto-retain and prefetch (fire-and-forget).
if let Some(ref hs) = ctx.hindsight {
    // Auto-retain this turn.
    if let Some(ref reply_text) = reply_text_for_retain {
        let hs_retain = Arc::clone(hs);
        let retain_input = input.clone();
        let retain_response = reply_text.clone();
        let retain_doc_id = session_uuid.clone();
        let retain_tags = vec![format!("chat:{chat_id}")];
        let now = chrono::Utc::now().to_rfc3339_opts(chrono::SecondsFormat::Secs, true);
        tokio::spawn(async move {
            let content = serde_json::json!([
                {"role": "user", "content": retain_input, "timestamp": now},
                {"role": "assistant", "content": retain_response, "timestamp": now},
            ]).to_string();
            if let Err(e) = hs_retain
                .retain(
                    &content,
                    Some("conversation between RightClaw Agent and the User"),
                    Some(&retain_doc_id),
                    Some("append"),
                    Some(&retain_tags),
                )
                .await
            {
                tracing::warn!("auto-retain failed: {e:#}");
            }
        });
    }
```

Note: `session_uuid` must be captured into `retain_doc_id` before the `tokio::spawn` move closure. The `chat_id` (i64) is Copy so it moves automatically.

- [ ] **Step 3: Verify workspace compiles**

Run: `devenv shell -- cargo build --workspace 2>&1 | tail -20`
Expected: clean build

- [ ] **Step 4: Run tests**

Run: `devenv shell -- cargo test --workspace 2>&1 | tail -30`
Expected: all tests pass

- [ ] **Step 5: Commit**

```bash
git add crates/bot/src/telegram/worker.rs
git commit -m "feat(worker): structured JSON retain with document_id and chat tags"
```

### Task 5: Update worker auto-recall and prefetch — tags and query truncation

**Files:**
- Modify: `crates/bot/src/telegram/worker.rs:536-552` (prefetch block)
- Modify: `crates/bot/src/telegram/worker.rs:820-842` (blocking recall)

- [ ] **Step 1: Add recall query truncation constant**

At the top of `crates/bot/src/telegram/worker.rs` (near other constants), add:

```rust
/// Maximum input query length for Hindsight recall (matches hermes recall_max_input_chars).
const RECALL_MAX_INPUT_CHARS: usize = 800;
```

- [ ] **Step 2: Add a truncation helper function**

Add this function near the constant (before `spawn_worker` or wherever helper functions live):

```rust
/// Truncate a string to at most `max` bytes on a valid UTF-8 char boundary.
fn truncate_to_char_boundary(s: &str, max: usize) -> &str {
    if s.len() <= max {
        return s;
    }
    // Find the largest valid char boundary <= max.
    let mut end = max;
    while end > 0 && !s.is_char_boundary(end) {
        end -= 1;
    }
    &s[..end]
}
```

- [ ] **Step 3: Update prefetch block with tags and truncation**

Replace the prefetch block at ~lines 536-552. This block comes right after the auto-retain `tokio::spawn` and is still inside the `if let Some(ref hs) = ctx.hindsight {` block:

```rust
    // Prefetch for next turn.
    let hs_recall = Arc::clone(hs);
    let recall_query = truncate_to_char_boundary(&input, RECALL_MAX_INPUT_CHARS).to_owned();
    let recall_tags = vec![format!("chat:{chat_id}")];
    let cache_key = format!("{}:{}", chat_id, eff_thread_id);
    let cache = ctx.prefetch_cache.clone();
    tokio::spawn(async move {
        match hs_recall.recall(&recall_query, Some(&recall_tags), Some("any")).await {
            Ok(results) if !results.is_empty() => {
                let content = rightclaw::memory::hindsight::join_recall_texts(&results);
                if let Some(ref c) = cache {
                    c.put(&cache_key, content).await;
                }
            }
            Ok(_) => {}
            Err(e) => tracing::warn!("prefetch recall failed: {e:#}"),
        }
    });
}
```

- [ ] **Step 4: Update blocking recall with tags and truncation**

Find the blocking recall at ~line 825. Replace:

```rust
match tokio::time::timeout(Duration::from_secs(5), hs.recall(input)).await {
```

with:

```rust
let truncated_query = truncate_to_char_boundary(input, RECALL_MAX_INPUT_CHARS);
let recall_tags = vec![format!("chat:{}", chat_id)];
match tokio::time::timeout(
    Duration::from_secs(5),
    hs.recall(truncated_query, Some(&recall_tags), Some("any")),
).await {
```

- [ ] **Step 5: Verify workspace compiles**

Run: `devenv shell -- cargo build --workspace 2>&1 | tail -20`
Expected: clean build

- [ ] **Step 6: Run tests**

Run: `devenv shell -- cargo test --workspace 2>&1 | tail -30`
Expected: all tests pass

- [ ] **Step 7: Commit**

```bash
git add crates/bot/src/telegram/worker.rs
git commit -m "feat(worker): add recall tags and query truncation (800 chars)"
```

---

### Task 6: Add unit test for truncation helper

**Files:**
- Modify: `crates/bot/src/telegram/worker.rs` (test module)

- [ ] **Step 1: Add tests for `truncate_to_char_boundary`**

Add these tests to the existing `#[cfg(test)] mod tests` block in `crates/bot/src/telegram/worker.rs`:

```rust
#[test]
fn truncate_to_char_boundary_short_string() {
    assert_eq!(truncate_to_char_boundary("hello", 800), "hello");
}

#[test]
fn truncate_to_char_boundary_exact_limit() {
    let s = "a".repeat(800);
    assert_eq!(truncate_to_char_boundary(&s, 800).len(), 800);
}

#[test]
fn truncate_to_char_boundary_over_limit() {
    let s = "a".repeat(1000);
    assert_eq!(truncate_to_char_boundary(&s, 800).len(), 800);
}

#[test]

### Task 7: Update ARCHITECTURE.md memory section

**Files:**
- Modify: `ARCHITECTURE.md:363-379` (Memory section)

- [ ] **Step 1: Replace the Hindsight mode paragraph**

In `ARCHITECTURE.md`, find the paragraph starting with `**Hindsight mode (optional):**` (~line 371) and replace everything from that line through the "Cron jobs skip memory" paragraph (before "Old tools") with:

```markdown
**Hindsight mode (optional):** Hindsight Cloud API (`api.hindsight.vectorize.io`),
one bank per agent. Three MCP tools exposed via aggregator:
`memory_retain`, `memory_recall`, `memory_reflect`. Prefetch cache is in-memory
(lost on restart → blocking recall on first interaction).

Auto-retain after each turn: content formatted as JSON array
(`[{"role":"user","content":"...","timestamp":"..."},{"role":"assistant",...}]`),
`document_id` = CC session UUID (same as `--resume`), `update_mode: "append"` for
delta retain (only new content triggers LLM extraction — O(n) cost vs O(n²) for
full-session replace). Tags: `["chat:<chat_id>"]` for per-chat scoping.
Context: `"conversation between RightClaw Agent and the User"`.

Auto-recall before each `claude -p`: query truncated to 800 chars, tags
`["chat:<chat_id>"]` with `tags_match: "any"` (returns per-chat + global untagged
memories). Prefetch uses same parameters.

**Cron jobs skip memory:** Cron and delivery sessions do not perform recall —
cron prompts are static system instructions, not user queries, so recall results
would be irrelevant and corrupt user memory representations (same approach as
hermes-agent `skip_memory=True`). Auto-retain after cron completion is still
active so cron results can be remembered (plain text summary, no document_id/tags).
```

- [ ] **Step 2: Commit**

```bash
git add ARCHITECTURE.md
git commit -m "docs: update ARCHITECTURE.md with hindsight retain alignment details"
```
