Ce Session Inventory

Session inventory

Agent-facing primitive. Discover session files and emit session metadata as JSONL across Claude Code, Codex, and Cursor.

This skill exists so that agents researching session history do not need to know the layout of session stores on disk or the JSONL shapes of each platform. The scripts under scripts/ own that knowledge.

Arguments

Space-separated positional args:

1. <repo> — repo folder name (e.g., my-project). Used for directory matching in Claude Code and Cursor, and as the CWD filter for Codex sessions.
2. <days> — scan window in days (e.g., 7). Session files older than this are skipped.
3. <platform> (optional) — one of claude, codex, cursor. Omit to search all three.

Execution

Run the discovery-plus-metadata pipeline from the skill's own scripts/ directory:

bash scripts/discover-sessions.sh <repo> <days> [--platform <platform>] \
  | tr '\n' '\0' \
  | xargs -0 python3 scripts/extract-metadata.py --cwd-filter <repo>

Return the raw stdout verbatim — one JSON object per session, then a final _meta line. Callers parse the JSONL directly, so do not paraphrase, reformat, or summarize.

If discovery finds no files, the pipeline still emits a clean _meta line (files_processed: 0). Return that as-is.

Output format

Each session line is a JSON object. Common fields across platforms:

• platform — claude, codex, or cursor
• file — absolute path to the session JSONL
• size — file size in bytes
• ts — session start timestamp (ISO 8601)
• session — session identifier

Platform-specific fields:

• Claude Code adds branch (git branch) and last_ts (last message timestamp).
• Codex adds cwd (working directory), source, cli_version, model, last_ts.
• Cursor has no in-file timestamps or metadata — ts is derived from file mtime and session from the containing directory name.

The final _meta line has files_processed, parse_errors, and optionally filtered_by_cwd (count of Codex sessions dropped by the CWD filter).

Error handling

If the discovery script errors (e.g., unreadable home directory, permission failure), let the error surface to the caller. Do not substitute git log, file listings, or other sources — this skill's contract is session metadata, nothing else.

If _meta reports parse_errors > 0, return the JSONL as-is. The caller decides how to handle partial data.
