Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Agent Activity Audit

This skill executes a structured pass over recent agent transcripts to learn what's working and
what's hurting. The original audit (May 2026) examined ~30 days of Claude Code and Codex sessions to
improve Sibyl itself — see `EXAMPLES.md` for the full reproducible run.

The output is a synthesis report grounded in real session evidence, plus per-group findings files
you can act on directly.

## When to use

- You maintain a system that agents call (CLI, MCP server, library, skill) and want signal beyond
  "did it work?"
- You suspect agents are stumbling on something but can't name what.
- A planning cycle is about to start and you want product priorities grounded in usage data, not
  vibes.
- A new release shipped and you want to see how it landed in the wild.

**Not for:** general code review, security audits, performance benchmarking. This skill reads
session transcripts; it doesn't analyze code.

---

## Agent rules (READ FIRST)

1. **Always write artifacts under `contexts/<analysis-name>-<date>/`.** Keep raw scans, episode
   extracts, and findings in one tree so the analysis is reproducible and the user can replay or
   extend it.

How to install

The exact contents, by fingerprint

mdr add hyperb1iss/sibyl/agent-activity-audit@sha256:6800591a03db1320

The line at the top of this page pins the label git:20260705.bfc8bde, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
