> Auto-memory captures. This plugin curates.

Claude Code's auto-memory (v2.1.32+) automatically records project patterns, debugging insights, and your preferences in `MEMORY.md`. This plugin adds the intelligence layer: it analyzes what Claude has learned, promotes proven patterns into project rules, and extracts recurring solutions into reusable skills.

## Quick Reference

| Command | What it does |
|---------|-------------|
| `/si:review` | Analyze MEMORY.md — find promotion candidates, stale entries, consolidation opportunities |
| `/si:promote` | Graduate a pattern from MEMORY.md → CLAUDE.md or `.claude/rules/` |
| `/si:extract` | Turn a proven pattern into a standalone skill |
| `/si:status` | Memory health dashboard — line counts, topic files, recommendations |
| `/si:remember` | Explicitly save important knowledge to auto-memory |

## Installation

### Claude Code (Plugin)
```
/plugin marketplace add alirezarezvani/claude-skills
/plugin install self-improving-agent@claude-code-skills
```

### OpenClaw
```bash
clawhub install self-improving-agent
```

### Codex CLI
```bash
./scripts/codex-install.sh --skill self-improving-agent
```

## Memory Architecture

### Where things live

| File | Who writes | Scope | Loaded |
|------|-----------|-------|--------|
| `./CLAUDE.md` | You (+ `/si:promote`) | Project rules | Full file, every session |
| `~/.claude/CLAUDE.md` | You | Global preferences | Full file, every session |
| `~/.claude/projects/<path>/memory/MEMORY.md` | Claude (auto) | Project learnings | First 200 lines |
| `~/.claude/projects/<path>/memory/*.md` | Claude (overflow) | Topic-specific notes | On demand |
| `.claude/rules/*.md` | You (+ `/si:promote`) | Scoped rules | When matching files open |

### The promotion lifecycle

```
1. Claude discovers pattern → auto-memory (MEMORY.md)
2. Pattern recurs 2-3x → /si:review flags it as promotion candidate
3. You approve → /si:promote graduates it to CLAUDE.md or rules/
4. Pattern becomes an enforced rule, not just a note
5. MEMORY.md entry removed → frees space for new learnings
```

## Core Concepts

### Auto-memory is capture, not curation

Auto-memory is excellent at recording what Claude learns. But it has no judgment about:
- Which learnings are temporary vs. permanent
- Which patterns should become enforced rules
- When the 200-line limit is wasting space on stale entries
- Which solutions are good enough to become reusable skills

That's what this plugin does.

### Promotion = graduation

When you promote a learning, it moves from Claude's scratchpad (MEMORY.md) to your project's rule system (CLAUDE.md or `.claude/rules/`). The difference matters:

- **MEMORY.md**: "I noticed this project uses pnpm" (background context)
- **CLAUDE.md**: "Use pnpm, not npm" (enforced instruction)

Promoted rules have higher priority and load in full (not truncated at 200 lines).

### Rules directory for scoped knowledge

Not everything belongs in CLAUDE.md. Use `.claude/rules/` for patterns that only apply to specific file types:

```yaml
# .claude/rules/api-testing.md
---
paths:
  - "src/api/**/*.test.ts"
  - "tests/api/**/*"
---
- Use supertest for API endpoint testing
- Mock external services with msw
- Always test error responses, not just happy paths
```

This loads only when Claude works with API test files — zero overhead otherwise.

## Agents

### memory-analyst
Analyzes MEMORY.md and topic files to identify:
- Entries that recur across sessions (promotion candidates)
- Stale entries referencing deleted files or old patterns
- Related entries that should be consolidated
- Gaps between what MEMORY.md knows and what CLAUDE.md enforces

### skill-extractor
Takes a proven pattern and generates a complete skill:
- SKILL.md with proper frontmatter
- Reference documentation
- Examples and edge cases
- Ready for `/plugin install` or `clawhub publish`

## Hooks

### error-capture (PostToolUse → Bash)
Monitors command output for errors. When detected, appends a structured entry to auto-memory with:
- The command that failed
- Error output (truncated)
- Timestamp and context
- Suggested category

**Token overhead:** Zero on success. ~30 tokens only when an error is detected.

## Platform Support

| Platform | Memory System | Plugin Works? |
|----------|--------------|---------------|
| Claude Code | Auto-memory (MEMORY.md) | ✅ Full support |
| OpenClaw | workspace/MEMORY.md | ✅ Adapted (reads workspace memory) |
| Codex CLI | AGENTS.md | ✅ Adapted (reads AGENTS.md patterns) |
| GitHub Copilot | `.github/copilot-instructions.md` | ⚠️ Manual promotion only |
