Install and use gstack in Capy and Claude Code. Load at session start to check this machine, and for gstack planning, code review, debugging, QA, design, security, documentation, and shipping workflows.
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
# gstack for Capy and Claude Code ## Session start: check, then install only when needed Resolve `scripts/install.sh` relative to this SKILL.md, not the working repository. It is a frozen bootstrapper: it prints `gstack-capy-skill: wrapper <n> (<path>)` first, learns the supported minimum from gstack's remote, and hands over to the checkout's own wrapper (`bin/gstack-capy-session`). 1. At session start run `bash scripts/install.sh --check`, adding `--for <skill>` when you know the workflow (`--for autoplan`, `--for review`, `--for qa`). It prints one `PASS|FAIL|SKIP <component>` row per component, a `GSTACK_LAUNCH:` line, and exactly one trailer as the last line: `gstack: ok <revision> for=<skill>` (exit 0) or `gstack: fail <ids> …` (exit 1). Read the exit status and grep `^gstack: ` directly; never pipe the check through `tail`, `head` or `grep` alone. `--check` never moves the checkout. …

How to install
mdr add garrytan/gstack/gstack@sha256:9efedc5ccf62014eThe line at the top of this page pins the label git:20261014.47d639a, 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.
