## What it does

The skill locates the active session transcript file and spins up three parallel reviewers: judgment, tooling, and divergent. Each subagent runs with `readonly: false` enabled. This write-enabled mode is required because subagents need MCP access to inspect ticket links, chat logs, and observability traces mentioned during the session. If the target harness lacks subagent tooling, the user must run the review roles sequentially.

A synthesizer reviews all findings and sorts them into accepted, rejected, and backlog buckets. Edits are never applied automatically: the skill presents the changes and waits for explicit user confirmation. Trivial edits are applied directly to local skill directories, while larger additions route to a skill authoring tool such as `create-skill`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --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 backnotprop/pstack --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 backnotprop/pstack --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 backnotprop/pstack reflect
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/backnotprop/pstack --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 backnotprop/pstack --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/backnotprop/pstack/tree/HEAD/skills/reflect/SKILL.md

## When to use it
- extract durable learnings from completed agent transcripts
- update existing project skills without manual drafting
- verify referenced traces and tickets across MCP tools
- route structural enforcement ideas into the devex backlog

## Example prompts
- reflect
- /reflect
- review the current transcript using reflect

# Reflect

Mine the current conversation for durable learnings, then route them into skill edits.

Invoke when the user says "reflect" or "/reflect". Skip when the conversation is trivial, off-topic, or already covered by an existing skill the parent followed correctly. One-offs are not learnings.

## 1. Locate the active transcript

Before fanning out, find this conversation's transcript in the active workspace's session directory. Do not glob across every project's directory. That crosses workspace boundaries and reads private chats from unrelated projects.

Where the transcript lives depends on your harness:

- **Cursor:** the `agent-transcripts/` directory the system prompt names.

  ```bash
  ls -t <agent-transcripts>/*.jsonl <agent-transcripts>/*/*.jsonl <agent-transcripts>/*/subagents/*.jsonl 2>/dev/null | head -10
  ```

  That covers the legacy flat (`<id>.jsonl`), current nested (`<id>/<id>.jsonl`), and subagent (`<parent>/subagents/<child>.jsonl`) layouts. For each candidate, read the first JSONL line. Take the file whose `message.content[0].text` contains the conversation's opening user prompt.
- **Claude Code:** `~/.claude/projects/<slug>/<session-id>.jsonl`, where `<slug>` is the workspace path with every character that isn't a letter or digit turned into "-".
- **Pi:** `~/.pi/agent/sessions/--<slug>--/*.jsonl`, where `<slug>` is the workspace path with the leading slash dropped and each "/" turned into "-".
- **Codex:** `~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`. Keep only files whose first line has `payload.cwd` equal to the workspace path.
- **Other harnesses:** check the harness's session directory for this workspace.

Outside Cursor, take the newest candidates first and confirm one by finding the conversation's opening user prompt in its first user message. If none matches, pass a tight digest of the session instead.

## 2. Spawn three reviewers in parallel

One message, three `Task` calls, `subagent_type: generalPurpose`, agent mode (`readonly: false`). Reviewers need MCP access to look up the tickets, chat threads, and observability traces the transcript references, and readonly strips MCPs.

**Other harnesses.** The spawns in this skill use Cursor's `Task` tool. In another harness, use its subagent tool: `Agent` in Claude Code (`subagent_type: general-purpose`), `task` in OpenCode (`subagent_type: general`), `spawn_agent` in Codex. Keep the prompt and the model. Drop parameters your tool doesn't have. If your harness has no subagent tool, as in Pi without an extension, run each role yourself, one after another.
