# Claude Code Sessions

Session intelligence plugin for Claude Code. Reads the JSONL session files that Claude Code writes to `~/.claude/projects/` and makes them searchable and analyzable.

## What It Does

Claude Code records every session as a JSONL file — messages, tool calls, token counts, diffs, tasks. This plugin reads those files and provides two interfaces. Most operations are read-only; delete and cleanup skills can remove session files when explicitly invoked.

**11 skills** usable directly in Claude Code:

| Skill | Purpose |
|-------|---------|
| `/session-search "query"` | Full-text search across every session |
| `/session-stats` | Token usage, model distribution, tool breakdown |
| `/session-list` | List sessions sorted by recency, size, or duration |
| `/session-detail` | Deep dive into a specific session |
| `/session-diff` | Compare two sessions — files, tools, topics |
| `/session-timeline` | Chronological view of sessions on a project |
| `/session-resume` | Generate a context recovery prompt from any session |
| `/session-tasks` | Find pending and orphaned tasks across sessions |
| `/session-export` | Export a session as clean markdown |
| `/session-cleanup` | Find empty, tiny, or stale sessions |
| `/session-delete` | Delete sessions and their associated tasks |

**Web dashboard** at `localhost:3000` with four views: Dashboard (summary stats), Sessions (sortable table with bulk operations), Search (full-text with context snippets), Tasks (grouped by status with orphan detection).

## Install

```bash
/plugin marketplace add apappascs/claude-code-sessions
/plugin install claude-code-sessions@claude-code-sessions
```

No API keys. No config. No runtime dependencies. It reads what's already on disk.

For the dashboard:

```bash
bun run ui
# → http://localhost:3000
```

## Architecture

Same TypeScript modules power skills, dashboard, and CLI:

```
lib/formatters.ts      — pure utilities, no I/O
lib/session-parser.ts  — parses one JSONL file into structured data
lib/session-store.ts   — scans all sessions, aggregates, searches
ui/server.ts           — HTTP endpoints + static file serving
```

Each lib file doubles as a standalone CLI:

```bash
bun run lib/session-store.ts list --sort recency --limit 10
bun run lib/session-store.ts search "database migration" --since 2025-01-01
bun run lib/session-parser.ts stats path/to/session.jsonl
```

## Use Cases

- Find the session where you solved a specific problem weeks ago
- See which projects consume the most tokens
- Track pending tasks across all sessions and projects
- Resume a past session with full context
- Compare how two sessions approached the same problem
- Export session transcripts for documentation
