Drive the pi CLI as a benchmark target or dispatched worker. Use when running pi probes, comparing pi postures, launching pi-zero, or handing work to a pi agent. Covers the flag surface that maps onto Skill Heaven mechanisms, model selection, and non-interactive invocation.
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
# pi Playbook `pi` is a coding agent CLI with a flag surface that maps unusually cleanly onto Skill Heaven's mechanisms — it can evict and readmit skills natively, so postures compose without any config-directory tricks. Verified against **pi 0.83.0**. Re-check `pi --version` before trusting any dose measurement; a flag's behaviour has changed across versions before (see §5). > **Rule 0 — run pi in a herdr pane, never through your Bash tool.** The operator must be able to > see which model you invoked. A probe the operator could not see is not evidence. Use > `pane send-text` with a trailing newline **inside** the quotes — **not** `pane run`, which > splits argv on whitespace and destroys quoted prompts: > > ```bash > herdr pane send-text "$PROBE_PANE" 'pi --model openai-codex/gpt-5.6-luna:low -p --no-session "probe text" > ' > herdr pane read "$PROBE_PANE" > ``` > **Building the door?** Read `packages/core/skills/harness-door-pattern/SKILL.md` first — it > carries the suppression-mechanism taxonomy, the probe methodology, and the traps. This playbook > is the harness-specific detail underneath it. --- ## 1. Model selection ```bash …

How to install
mdr add gaia-research/gaia-skill-heaven/pi-playbook@sha256:20d326440ee7940aThe line at the top of this page pins the label git:20260810.ae24947, 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.
