hippo project health check — inspects the ledger, the clerks, directive hygiene and waste patterns, then proposes cleanups. Use when the user asks for "/hippo:checkup", "check the project", "look for waste", "tidy the directives", or "how are the clerks doing".
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
# hippo: checkup The project-level `/doctor`. Diagnose everything read-only, report, and apply cleanups only after confirmation. With no `.hippo/`, answer in one line — "hippo is not initialized — run `hippo init`" — and stop. ## Calling the tools In Claude Code `hippo` is on PATH. **In Codex it is not** — resolve `../../bin/hippo` relative to this SKILL.md into an absolute path and call that. The transcript compressor is `../../scripts/digest_lite.py` (same resolution; stdlib-only): `python3 <plugin>/scripts/digest_lite.py <transcript.jsonl> [--since-line N]`. Transcripts live under `~/.claude/projects/<project cwd with "/" replaced by "-">/` (Claude Code) or `~/.codex/sessions/` in dated subdirectories (Codex) — take the newest few by mtime. `.hippo/cursors.json` maps session id → the last transcript line the scribe has read. ## Ground rules (inherited from the doctor contract) - **Propose → confirm → apply, at most two questions.** (1) One cleanup bundle, with the recommended option first and marked "(recommended)" and the decline option last. (2) Changes that need separate approval (editing documents, say) go in a second question. Edit no file before confirmation. …

How to install
mdr add dev-jahn/hippocampus/checkup@sha256:f6ed8f2b328095c4The line at the top of this page pins the label git:20261001.82e441a, 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.
