Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00187 | $0.02595 |
| Opus 5 | $0.00093 | $0.01298 |
| Sonnet 5 | $0.00037 | $0.00519 |
| Haiku 4.5 | $0.00019 | $0.00260 |
Grade A, and why
gate-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.
gate-runner
Execute the host project's quality gates in a fixed sequence and emit a
structured report the caller uses to decide merge readiness. You detect the
project's runner, resolve a gate plan, run the gates, and return a verdict.
You never create a merge request or pull request, and you never supply
functional browser evidence — that belongs to acceptance-check.
Blast radius: R0 (read-only detection, diff, manifest inspection) plus
R1 (writes only under <run_dir> and standard test output paths). Never
write repo files outside those locations. Run user-provided plan commands
exactly — no rewriting.
Inputs
| Input | Meaning | Default |
|---|---|---|
branch |
branch under test | required |
merge_base |
base ref for the diff | origin/main |
repo_path |
repository root | required |
run_dir |
directory for cache + report writes | required |
Compute the change set once with:
git diff --name-only <merge_base>...HEAD
Gate order (fixed)
lintbuildunitaffected(changed-file-aware tests)ui(conditional — only when the diff touches a UI surface)
Step 1 — Resolve the gate plan
Two resolution modes. Prefer the guide.
Guide-first. If a rendered gate registry file exists, read it and run exactly the gates it lists, in the order it lists them. Guide file paths, top-level preferred over the standards subpath:
.agentic/guides/quality-gates.md.agentic/guides/standards/quality-gates.md
When both exist, the top-level path wins. Do not invent, swap in, or auto-detect any gate ahead of what this file specifies.
Fallback auto-detection. Fall back to runner auto-detection only when the guide file does not exist and the caller is not inside a foundation-required full run. A foundation-required run expects the guide to be present.
Runner detection (first match wins; npm is never assumed by default)
| Manifest | Runner | lint / build / test / ui |
|---|---|---|
package.json + pnpm-lock.yaml |
pnpm | pnpm lint / pnpm build / pnpm test / pnpm test:ui |
package.json + yarn.lock |
yarn | yarn lint / yarn build / yarn test / yarn test:ui |
package.json (other/no lock) |
npm | npm run lint / npm run build / npm test / npm run test:ui |
Cargo.toml |
cargo | cargo clippy -- -D warnings / cargo build / cargo test / (no UI) |
pyproject.toml [tool.poetry] |
poetry | poetry run ruff check / poetry run python -m compileall . / poetry run pytest |
pyproject.toml [tool.uv] or uv.lock |
uv | uv run ruff check / uv run python -m compileall . / uv run pytest |
pyproject.toml (other) |
python | ruff check / python -m compileall . / pytest |
go.mod |
go | go vet ./... / go build ./... / go test ./... / (no UI) |
| none | unknown | ask user once |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gate-runner is a skill published in the GitHub repository Jarroslav/agentic-os (0 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 187 tokens to every session and 2,595 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
