Preregister a paid eval (bars, arms, decoys, stop rules), dry-run it at zero cost, then run a three-item priced pilot whose spend table gates approval. (gstack).

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.

## Shared preamble (load first)

This skill follows gstack shared preamble `4e82fa4c839f` (AskUserQuestion format, voice, writing, completeness and completion rules). If your Read of that file, headed by this id, is still in context, do not read it again; otherwise Read `~/.claude/skills/gstack/eval-plan/sections/preamble.md` in full before the command below. A section or subsection here with a shared heading replaces the shared one.

## Preamble (run first)

```bash
~/.claude/skills/gstack/bin/gstack-skill-start --skill "eval-plan" --model "claude"
```

Read the echoed `KEY: value` STATUS lines — they drive every preamble rule
below. **Degraded mode:** if `SKILL_START_PROTO: 1` is missing from the output
(script absent, stale install, or a different protocol number), apply safe
defaults: treat `SESSION_KIND` as `interactive`, do NOT assume Conductor,
skip onboarding/telemetry steps (their gates are marker-based, so consent and
onboarding prompts are DEFERRED to the next healthy run — never lost), tell
…

How to install

The exact contents, by fingerprint
mdr add garrytan/gstack/eval-plan@sha256:9d49e9e92307ee32

The line at the top of this page pins the label v1.0.0, 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.
