## What it does

The skill runs in four phases. First it gathers signal: a stats script over `.harness/ledger.jsonl`, the project rules in `CLAUDE.md`, recent `feedback` memories, and the last report under `.harness/reflections/`. Then it clusters what repeats. Every `recurring <rule> <prefix> <count>` line marks one friction cluster; one-off events get dropped.

Each cluster gets exactly one proposal, and the type depends on the problem. A convention goes into the project section of `CLAUDE.md`. A guardrail that fires too often or too rarely becomes a diff to `.claude/settings.json` or the hook. A mechanically catchable mistake turns into a lint rule for `eslint.config.mjs` or `biome.jsonc`. The durable “why” lands in a memory file or `docs/adr/`. All proposals arrive as one numbered list, and none of them is applied on its own.

You approve, edit or reject each item, the approved ones are committed, and a report with the metric snapshot and the reasons for rejections is written to `.harness/reflections/YYYY-MM-DD.md`. The report is tracked in git; the raw ledger stays gitignored. One thing to know up front: the stats script normally lives in `~/.claude/hooks/`, so without the hooks installed you have to run it from wherever the project keeps them. All zeros in the output mean no signal has been captured yet, and the skill stops there.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sneg55/agent-starter --skill reflect -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sneg55/agent-starter --skill reflect -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sneg55/agent-starter --skill reflect -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sneg55/agent-starter reflect
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sneg55/agent-starter --skill reflect -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sneg55/agent-starter --path skills/reflect
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sneg55/agent-starter --skill reflect -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/sneg55/agent-starter/tree/HEAD/skills/reflect/SKILL.md

## When to use it
- spot checks that keep firing in the same part of the codebase
- turn a developer correction from a `feedback` memory into a project rule
- loosen or tighten a guardrail threshold without editing the hook by hand
- add a lint rule for a mistake a machine can catch
- record the reasoning behind a decision in `docs/adr/` so it stops coming back

## Example prompts
- Run reflect and show me which checks recur most often
- Cluster the entries in `.harness/ledger.jsonl` and draft one change per cluster
- Write the reflection report to `.harness/reflections/` and compare the metric with last time

# Reflect: Per-Project Self-Improvement

You are performing a reflection - turning the signal this project has captured
into durable improvements. Nothing is applied without the developer's approval.

## Phase 1 - Orient (gather signal)

- Run the stats script over the ledger:
  `~/.claude/hooks/harness-ledger-stats.sh --ledger .harness/ledger.jsonl --min-recurr 3`
  If that path doesn't exist, the hooks aren't installed at `~/.claude/hooks/` - run the
  copy from wherever this project keeps them. If the script prints all zeros there is no
  ledger yet (no signal captured) - stop; there is nothing to reflect on.
- Read the current project rules in `CLAUDE.md` so you improve them rather than duplicate.
- Read recent `feedback`-type memory files - these are the developer's explicit
  corrections and are the highest-value signal. Locate the memory directory first
  (it sits next to `MEMORY.md`; `find . -name MEMORY.md` if unsure), then
  `grep -l 'type: feedback' <memory-dir>/*.md`.
- Read the most recent `.harness/reflections/*.md` report (if any) to recall the last
  metric snapshot and what was already changed.

## Phase 2 - Cluster

From the stats output and feedback memories, identify recurring problems:
- Each `recurring <rule> <prefix> <count>` line is a friction cluster - the same check
  keeps firing in the same area.
- Group related feedback corrections by theme.
- Ignore one-off events; focus on what repeats.

## Phase 3 - Propose (one candidate per cluster)

For each cluster, draft exactly one proposed change, choosing the fitting type:

| Type | When | Where it lands |
|------|------|----------------|
| **Project rule** | a convention would stop the repeat | append to `CLAUDE.md` project-specific section |
| **Threshold change** | a guardrail is too strict/loose | a diff to `.claude/settings.json` or the hook - **shown, never auto-applied** |
| **Lint rule** | the mistake is mechanically catchable | a diff to `eslint.config.mjs` / `biome.jsonc` |
| **ADR / knowledge** | durable "why" worth keeping | a new memory file or `docs/adr/` note |
```
