## What it does

The skill parses markdown files inside `$CLAUDE_PROJECT_DIR/.claude/cache/learnings/` to locate recurring workflows and friction points. It inspects sections covering techniques, takeaways, and failures, then compiles a frequency table across past sessions.

A decision tree determines how each pattern is preserved. Step-by-step procedures become executable skills in `.claude/skills/`, heuristics become markdown rules in `.claude/rules/`, and automated gates turn into shell hooks. It prompts for explicit user approval via `AskUserQuestion` before generating any file.

This skill depends entirely on pre-existing session files in `.claude/cache/learnings/`. If your setup does not save session notes to that directory, the skill has nothing to process.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill compound-learnings -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/compound-learnings/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/compound-learnings/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill compound-learnings -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/compound-learnings/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill compound-learnings -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/compound-learnings/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 compound-learnings
```

2. **Manually: put the files in place**
- File: `.github/skills/compound-learnings/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill compound-learnings -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/compound-learnings
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/compound-learnings/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill compound-learnings -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/compound-learnings/SKILL.md

## When to use it
- convert past session notes into permanent agent rules
- turn recurring multi-step workflows into executable skills
- generate shell hooks for automatic pre-commit or session checks
- identify repeated coding mistakes across historical sessions

## Example prompts
- Review recent session learnings and suggest new rules
- Improve my setup based on recent work
- Turn learnings into skills and hooks

# Compound Learnings

Transform ephemeral session learnings into permanent, compounding capabilities.

## When to Use

- "What should I learn from recent sessions?"
- "Improve my setup based on recent work"
- "Turn learnings into skills/rules"
- "What patterns should become permanent?"
- "Compound my learnings"

## Process

### Step 1: Gather Learnings

```bash
# List learnings (most recent first)
ls -t $CLAUDE_PROJECT_DIR/.claude/cache/learnings/*.md | head -20

# Count total
ls $CLAUDE_PROJECT_DIR/.claude/cache/learnings/*.md | wc -l
```

Read the most recent 5-10 files (or specify a date range).

### Step 2: Extract Patterns (Structured)

For each learnings file, extract entries from these specific sections:

| Section Header | What to Extract |
|----------------|-----------------|
| `## Patterns` or `Reusable techniques` | Direct candidates for rules |
| `**Takeaway:**` or `**Actionable takeaway:**` | Decision heuristics |
| `## What Worked` | Success patterns |
| `## What Failed` | Anti-patterns (invert to rules) |
| `## Key Decisions` | Design principles |

Build a frequency table as you go:

```markdown
| Pattern | Sessions | Category |
|---------|----------|----------|
| "Check artifacts before editing" | abc, def, ghi | debugging |
| "Pass IDs explicitly" | abc, def, ghi, jkl | reliability |
```

### Step 2b: Consolidate Similar Patterns

Before counting, merge patterns that express the same principle:

**Example consolidation:**
- "Artifact-first debugging"
- "Verify hook output by inspecting files"
- "Filesystem-first debugging"
→ All express: **"Observe outputs before editing code"**

Use the most general formulation. Update the frequency table.

### Step 3: Detect Meta-Patterns

**Critical step:** Look at what the learnings cluster around.

If >50% of patterns relate to one topic (e.g., "hooks", "tracing", "async"):
→ That topic may need a **dedicated skill** rather than multiple rules
→ One skill compounds better than five rules

Ask yourself: *"Is there a skill that would make all these rules unnecessary?"*

### Step 4: Categorize (Decision Tree)

For each pattern, determine artifact type:

```
Is it a sequence of commands/steps?
  → YES → SKILL (executable > declarative)
  → NO ↓

Should it run automatically on an event (SessionEnd, PostToolUse, etc.)?
  → YES → HOOK (automatic > manual)
  → NO ↓

Is it "when X, do Y" or "never do X"?
  → YES → RULE
  → NO ↓

Does it enhance an existing agent workflow?
  → YES → AGENT UPDATE
  → NO → Skip (not worth capturing)
```
