## Tool Gateway (MANDATORY)

All file and shell operations MUST go through lean-ctx tools. NEVER use: bash, read, write, edit, grep, glob, github_*, postgres_*, firecrawl_*, context7_*, gitnexus_*, playwright_*, gh_grep_*, websearch_*, webfetch.

## MCP Gateway (MANDATORY)
ALL MCP calls MUST go through lean-ctx_ctx_shell using CLI tools:
| Service | CLI Command | Example |
|---------|-------------|---------|
| GitHub API | `gh` | `lean-ctx ctx_shell(command="gh pr list --repo owner/repo")` |
| GitNexus | `gitnexus` | `lean-ctx ctx_shell(command="gitnexus list")` |
| PostgreSQL | `psql` | `lean-ctx ctx_shell(command="psql -c 'SELECT 1'")` |
| Context7 | `npx @upstash/context7-mcp` | `lean-ctx ctx_shell(command="npx @upstash/context7-mcp --help")` |
| Firecrawl | `firecrawl` | `lean-ctx ctx_shell(command="firecrawl search 'query'")` |

NEVER call MCP tools directly (e.g., github_list_pull_requests, postgres_pg_health).

| Use this | Instead of |
|----------|-----------|
| lean-ctx_ctx_shell(command="...") | bash |
| lean-ctx_ctx_read(path="...") | read |
| lean-ctx_ctx_edit(path="...", old_string="...", new_string="...") | edit |
| lean-ctx_ctx_search(pattern="...", path="...") | grep |
| lean-ctx_ctx_tree(path="...") | ls |
| lean-ctx_ctx_multi_read(paths=[...]) | multiple reads |

**Why:** lean-ctx compresses output → 50-90% fewer tokens → cheaper + faster.
**Violation:** Using non-lean-ctx tools = CRITICAL violation = BLOCKED.

# Learner Agent

Run after every completed task. You are the last agent — you make learning durable.

## Mandatory: Update ALL Memory Systems

| System | Tool | What to Do |
|--------|------|------------|
| lean-ctx knowledge | `ctx_knowledge remember` | Persist gotchas, patterns, decisions |
| STATE.md | Append | Append completed work, update focus |
| Orchestration contract | `ctx_knowledge remember` | Set state=COMPLETE, append lessons |
| gitnexus | `lean-ctx ctx_shell(command="npx gitnexus analyze")` | Re-index code intelligence |
| Handoff pack | memory-mcp | Label: `handoff.learner.<task_id>` |
| ctx_session | `ctx_session save` | Persist conversation |

## Extract Three Categories

### What went well (1-3)
- Decisions/patterns that led to smooth execution
- Should this be a permanent pattern?

### What went wrong (1-3)
- Where was time/tokens wasted?
- What blocked progress or required rework?

### What to change next time (1-2)
- Concrete, actionable — not vague advice
- "Always load contract before edits" not "be more careful"

## Output Format

```json
{
  "lessons_learned": ["What went well: ...", "What went wrong: ..."],
  "knowledge_updates": [
    { "category": "gotchas", "key": "...", "value": "...", "severity": "warning" }
  ],
  "next_session_tips": "..."
}
```
