inscript

Universal agent activity ledger.

When an AI agent works on code, inscript records everything: which project, which files, what changed. Any tool can read ~/.inscript/ for context.

Install

pip install inscript

What it records

~/.inscript/
  active_project              ← which codebase right now
  active_session              ← current session ID
  config.toml                 ← retention policy
  sessions/
    <session-id>/
      meta.json               ← start time, project, status
      touches.jsonl           ← every file read/edit/write
      diffs.jsonl             ← raw changes (Edit old→new, Write content hash)
      summary.json            ← stats written on session end
  overlap/
    <project-hash>.jsonl      ← when 2+ sessions touch the same files

Setup

inscript init    # configure retention, storage, diffs

Then add hooks to ~/.claude/settings.json:

{
  "hooks": {
    "SessionStart": [
      {
        "hooks": [{ "type": "command", "command": "inscript-hook" }]
      }
    ],
    "PostToolUse": [
      {
        "matcher": "Read|Edit|Write|Glob|Grep",
        "hooks": [{ "type": "command", "command": "inscript-hook", "async": true }]
      }
    ],
    "Stop": [
      {
        "hooks": [{ "type": "command", "command": "inscript-hook" }]
      }
    ]
  }
}

CLI

inscript              # status: active project + session
inscript log          # activity log for current session
inscript log <id>     # activity log for a specific session
inscript overlap      # show file collisions across sessions
inscript export <id>  # export session as markdown
inscript cleanup      # enforce retention policy
inscript init         # setup wizard

Python API

from inscript_pkg import active_project, active_session, list_sessions

project = active_project()    # Path or None
session = active_session()    # session ID or None
all_sessions = list_sessions()  # [{session_id, start_time, project, status}, ...]

How it works

Three Claude Code hooks write to ~/.inscript/:

• SessionStart → creates sessions/<id>/meta.json
• PostToolUse → appends to touches.jsonl and diffs.jsonl
• Stop → writes summary.json with session stats

Any MCP server, script, or tool can read these files. No coordination needed. The agent doesn't know inscript exists.

Overlap detection

When two Claude Code sessions work on the same project simultaneously, inscript records which files both sessions touch. Run inscript overlap to see collisions.
