gstack-sprint skillA
gstack-sprint is agent-read markdown (skill) from sehoon787/my-codex: 3-Phase Sprint workflow — design → execute → review with user interaction at decision points.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<Purpose>
gstack-sprint wraps the 3-Phase Sprint workflow (design→execute→review) as a structured skill to guarantee deterministic execution. Without this skill, the 3-Phase workflow exists only as prompt instructions in boss.md and may be forgotten during long sessions. This skill is the single entry point for end-to-end feature implementation — it coordinates design, execution, and review with user confirmation at each phase boundary.
</Purpose>
<Use_When>
- End-to-end feature implementation ("build this feature", "design it and implement it")
- Build or Mid-sized intent type with implementation phase included
- User says "sprint", "end-to-end", "e2e implementation"
</Use_When>
<Do_Not_Use_When>
- Pure design/planning/idea review without implementation → use /office-hours or /plan-ceo-review directly
- Architecture intent type (design only, no build)
- "just design it", "just plan it", "review my idea" — these route to /office-hours or /plan-ceo-review
- Single-purpose requests: code review → /review, QA → /qa, deploy → /ship
- Trivial fixes, research, documentation
</Do_Not_Use_When>

End-to-end feature work fails silently in three predictable ways:

How to install
mdr add sehoon787/my-codex/gstack-sprint@git:20260407.23ae8admdr add sehoon787/my-codex/gstack-sprint@sha256:33c50cd9850824c6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
