What it does
Ghm Gate Check is an agent skill from mattgierhart/PRD-driven-context-engineering. Validates gate criteria before PRD lifecycle advancement by delegating to the readiness scoring pipeline (scripts/readiness.py). Returns a graduated PASS / WARN / BLOCK verdict with top blockers and their causal chain. Triggers before advancing from v0.X to v0.Y or explicit /ghm-gate-check.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files and assets (for example `assets/gate-checklist-template.md`, `references/examples.md` and `references/gate-criteria.md`).
It sits in Product & Project Management, covering PRD writing. The repository describes itself as: PRD-Led Context Engineering — Memory as Infrastructure. An ontology layer for product teams building products that solve real problems — with AI agents that remember. Gated PRD… The licence is MIT.

Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 30ed1b0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ghm Gate Check loads about 1.3k tokens when it runs, and up to ~6.9k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 471 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Glob, Grep
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Gate Check
Validate whether the PRD stage is ready to advance to the next version. Delegates to the three-layer readiness scorer — SoT files → EPICs → stage — then surfaces the leverage view (what to fix first, and which EPICs it unblocks).
Workflow Overview
- Compute → run
scripts/readiness.py run --quietto refreshstatus/readiness.json - Read → parse
status/readiness.json - Report → PASS / WARN / BLOCK verdict with top blockers and causal links
- Recommend → actionable next steps (always highest-leverage first)
Authority
references/gate-criteria.md remains the canonical source of mandatory artifacts per gate. The scorer's GATE_REQUIREMENTS table mirrors it. Do not hand-roll checklists here — the scoring engine is the single source of truth.
Step 1: Compute
Run the orchestrator. It runs SoT → EPIC → stage in dependency order and writes status/readiness.json.
python scripts/readiness.py run --quiet
# exit 0 = all pass, 1 = warn, 2 = block, 3 = errorIf the exit code is 3, report a runtime error and stop. If 0/1/2, proceed to Step 2.
Fallback: no scripts available
If scripts/readiness.py is missing or Python is unavailable, fall back to reading status/readiness.json directly. If that's also absent, report: "Readiness not yet computed — install scripts/requirements.txt and run python scripts/readiness.py run."
Step 2: Read
cat status/readiness.jsonExtract:
summary.current_stage— the gate being evaluated and its scoresummary.top_blockers— ranked SoT files blocking progressstages.{target}— detailed stage block (dimensions, unmet_criteria, caps)epics.{id}— per-EPIC scores (cite the lowest ones)
Step 3: Report
Use this template. Fill every field from the JSON — do not improvise scores.
## Gate Check Report: {stage.gate_description}
**Verdict**: [PASS | WARN | BLOCK]
**Stage Score**: {stage.score} / 100 (warn < {threshold_warn}, block < {threshold_block})
**Date**: {now}
### Stage Dimensions
| Dimension | Score | Weight |
|-----------|-------|--------|
| required_ids_present | {score} | {weight} |
| relevant_sot_readiness | {score} | {weight} |
| cross_ref_integrity | {score} | {weight} |
| downstream_epic_readiness | {score or "n/a"} | {weight or "—"} |
### Top Blockers (leverage view)
1. **{file}** (score {score}) — blocks {N} EPICs: {EPIC-XX, …} — impact {impact}
2. …
### Unmet Criteria (high severity first)
- [high] {ref}: {reason}
- [medium] {ref}: {reason}
### Recommendation
**If PASS**: Advance to {next_version}. Run `ghm-status-sync` to update the README dashboard.
**If WARN / BLOCK**: Do not advance. Address top blockers in order — fixing the highest-impact SoT file cascades up the graph.
**Next action**: {top_blockers[0] → concrete fix}Verdict bands
| Stage score | Verdict | Meaning |
|---|---|---|
| ≥ 70 | PASS | Safe to advance |
| 50–69 | WARN | Advance with documented risk; log in PRD change log |
| < 50 | BLOCK | Cannot advance — per rule 05-lifecycle-gates, update the EPIC and STOP |
Step 4: Recommend
Always prioritize by impact = (100 − score) × #EPICs blocked. The top blocker is the single highest-leverage fix; cite its blocking_epics list so the human understands what unblocks.

Quality Gates
- Stage score cited from JSON, not estimated
- Top blockers include their consumer EPICs
- Recommendation is actionable (specific file, specific action)
- Verdict matches the score band exactly (don't round up)
Anti-Patterns
| Pattern | Example | Fix |
|---|---|---|
| Ignoring the score | "Feels ready; pass" | Cite stage.score verbatim |
| Skipping blockers | "Minor stuff, advance anyway" | Block if score < 50; warn if < 70 |
| Hand-rolling criteria | Re-checking IDs manually | Trust the scorer; if wrong, fix GATE_REQUIREMENTS in _readiness/stage.py |
| Forcing PASS | Overriding the verdict | Never override; the score is the contract |
Boundaries
DO:
- Delegate computation to
readiness.py - Cite specific scores, files, and EPICs from the JSON
- Surface the
top_blockersleverage view
DON'T:
- Modify
status/readiness.jsondirectly — it's computed output - Create missing artifacts inside this skill (that's the author's job)
- Override PASS/BLOCK verdicts subjectively
Handoff
After a report:
- PASS: Trigger
ghm-status-sync; the gate advancement updates the README dashboard - WARN: Same as PASS but note the risks in the PRD change log
- BLOCK: Return control to the human. The
top_blockers[0]fix is the single most important next action
