## What it does

The skill instructs the agent how to search through JSON-lines logs in `~/.claude/projects/`. Claude Code encodes project folder paths by turning slashes into hyphens. Instead of reading large log files with `cat` and wasting context on raw data, the agent runs focused command-line tools.

Search uses `rg` to find candidate files while skipping nested subagent logs. After narrowing matches down, it extracts dialogue turns using `jq` or bounded line context. The result includes the session ID, timestamp, and a summary spanning two to four sentences.

You need `rg` and `jq` available in your system path for this workflow. The skill searches local transcripts only, leaving repository code, pull request discussions, and external tools like Jira aside.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add donnfelker/donnfelker-plugin-marketplace --skill find-past-conversation -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add donnfelker/donnfelker-plugin-marketplace --skill find-past-conversation -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add donnfelker/donnfelker-plugin-marketplace --skill find-past-conversation -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install donnfelker/donnfelker-plugin-marketplace find-past-conversation
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add donnfelker/donnfelker-plugin-marketplace --skill find-past-conversation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/donnfelker/donnfelker-plugin-marketplace --path plugins/find-past-conversation/skills/find-past-conversation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add donnfelker/donnfelker-plugin-marketplace --skill find-past-conversation -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/donnfelker/donnfelker-plugin-marketplace/tree/HEAD/plugins/find-past-conversation/skills/find-past-conversation/SKILL.md

## When to use it
- locate an older Claude Code session ID using a remembered error message
- recall architectural decisions made in a previous session without reading raw logs
- check whether past work resulted in a git commit or an opened pull request
- prevent token exhaustion when inspecting multi-megabyte session histories

## Example prompts
- Search your past sessions for the discussion about Stripe webhook retries
- Find the conversation where we resolved the database connection timeout
- Remind me what came out of the caching refactor session last week

description: "Searches past Claude Code session transcripts under ~/.claude/projects/ to recover a previous conversation by recalled phrase, error string, or topic. Use when the user says 'search your history for', 'find the conversation about', 'look through your past sessions', 'did I ever finish that work on', 'what did we decide about X last week', 'remind me what came out of that session', or otherwise asks you to recall a prior session. Returns session ID, project, date, and a 2-4 sentence summary; on request, also reports the outcome (commit, branch, PR opened or merged). Not for searching the current codebase, current PR comments, or external systems like Slack/Jira — for those, see codebase-analyzer and address-pr-comments."

# Find a Past Claude Code Conversation

You are helping the user recall a previous Claude Code session. They remember roughly *what* was discussed, and they want you to find the actual transcript — the session ID, when it happened, a short summary, and (if relevant) what shipped from it.

Claude Code stores every session as a JSON-lines file under `~/.claude/projects/`. This skill tells you how to search those transcripts efficiently without burning context on multi-megabyte log files.

## When to use this skill

Trigger on phrases like:

- "search your history for [topic]"
- "find the conversation we had about [topic]"
- "look through your past sessions for [topic]"
- "did I ever finish that work on [topic]"
- "what did we decide about [topic] last week"
- "remind me what came out of the [topic] session"

Do **not** use this for searching the current codebase, the current PR's comments, or external systems like Slack/Jira — those have their own skills and tools.

## How transcripts are organized

```
~/.claude/projects/
├── -Users-alice-source-acme-api/
│   ├── 06c5c59e-0735-...jsonl          # one session = one file
│   ├── a7e955d8-cf10-...jsonl
│   └── a7e955d8-cf10-.../
│       └── subagents/
│           └── agent-ab42fde6...jsonl  # subagent transcripts
├── -Users-alice-source-acme-worker/
└── ...
```

Important facts:

- **The project folder is the working directory with `/` replaced by `-`.** So a session run in `/Users/alice/source/acme/api` lives under `~/.claude/projects/-Users-alice-source-acme-api/`.
- **The session ID is the filename without `.jsonl`** — e.g. `a7e955d8-cf10-42ec-a36b-0fe2bcb42d45`.
