What it does

Enforces a lean GitHub Actions Flutter CI where every gate maps to one named release-blocking contract — pinned runner + subosito/flutter-action@v2 toolchain, dart format --set-exit-if-changed, flutter analyze --fatal-infos, build_runner and drift schema freshness (git diff --exit-code), flutter test --test-randomize-ordering-seed random, static import/banned-string greps that catch what runtime can't, coverage-as-report-never-a-gate with the upward-lie fixed, verify-never-bless goldens (no --update-goldens in CI), and an honest statement of what CI cannot prove (audio, real fonts, on-device…

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

6# CI Pipeline & Gates
7
8A CI gate is not a decorative green check — it converts one release-blocking contract into a check a build either passes or fails, *without trusting a human*. Keep the pipeline lean: one workflow file for most single-package apps, every job pinned, every gate traceable to a named contract, and an honest note wherever CI cannot prove the thing that actually matters.

12- references/workflow-skeleton.md — the copy-paste single-file ci.yml: pinned runner + toolchain, freshness gates, format/analyze, randomized tests, host-sqlite, coverage-strip, and the release-build job.
13- references/policy-grep-gate.md — the grep-based invariant gate: the three-criteria bar, strip-comments-first, anchor-to-structure, accumulate-and-fail-once, write-the-reason-for-a-stranger.

17## Non-negotiable rules
18
191. **Every gate maps to exactly one named contract — name it.** A check that serves no stated contract is not a gate: make it advisory and say so, or don't add it. Never invent a merge-blocker with nothing behind it. This keeps the pipeline auditable and stops gate-sprawl.
202. **Pin the runner AND the toolchain on every job.** runs-on: ubuntu-24.04 (never -latest — image drift moves lcov/toolchain versions with no diff to review) and subosito/flutter-action@v2 with an explicit flutter-version or flutter-version-file, channel: stable. A floating SDK silently re-renders goldens and perturbs determinism. Bump the version only in a dedicated PR.
213. **Mark unverified action versions inline; never invent a major.** A wrong major silently fails or silently changes behaviour. Write # VERIFY: next to a version you haven't confirmed rather than guessing @v7.
224. **Format and analyze are hard gates.** dart format --output=none --set-exit-if-changed . and flutter analyze --fatal-infos. --fatal-infos is load-bearing: an info left unfixed is a warning that gets ignored next. See lint-and-style-config.
235. **Codegen and schema are freshness gates, not build steps.** Run the generator, then git diff --exit-code the outputs; a nonzero diff fails with a message telling the author to regenerate and commit. This is the entire mitigation for committing generated code, and the one gate that catches "changed the schema, forgot to migrate". See run-codegen, run-migration.
246. **Randomize test ordering; provision native deps the test host needs.** flutter test --test-randomize-ordering-seed random is free detection of inter-test state leakage. On Linux, flutter test runs in a plain Dart VM where sqlite3_flutter_libs does nothing — install host sqlite3 before a suite that opens a real DB, or it fails for a reason that looks like a broken repo.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈230
always loaded
The name and description, so the model knows the skill exists and when to reach for it.

3.8%
of a 200k window
Ten skills this size would take about 38% of the window before you open a file.
050k100k150k200k context window

7.6k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

The download carries 5 of the 6 files in its source folder; the list here names 5 files, 35.5 kB on disk. Mostly text — the instructions the model reads — with 2 scripts in it that your client would run only if the instructions tell it to. The other one is not in the download — listed after these, with why.

  • SKILL.md16.3 kB
  • references/policy-grep-gate.md6.0 kB
  • references/workflow-skeleton.md8.2 kB
  • scripts/banned-strings.sh2.7 kB
  • scripts/ci-gates.sh2.3 kB

Not in the download

Not carried is a type a skill download does not hold. Marked read: its SKILL.md or scripts name the file, so without it the skill works only in part. Take it from its source.

What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 2 scripts beside the text, so the download is 5 files — not the whole of its source: 1 file is left out, and the skill reads it. It is listed under the files, with why. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# CI Pipeline & Gates · 7.6k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/ci-pipeline-gates/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ci-pipeline-gates" ] && { [ ! -e .claude/skills/ci-pipeline-gates ] || { mv .claude/skills/ci-pipeline-gates "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ci-pipeline-gates" .claude/skills/ && echo "Installed .claude/skills/ci-pipeline-gates"

npx mcprush@latest skill add zakariaf/ci-pipeline-gates

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/ci-pipeline-gates/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/ci-pipeline-gates/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ci-pipeline-gates" ] && { [ ! -e ~/.claude/skills/ci-pipeline-gates ] || { mv ~/.claude/skills/ci-pipeline-gates "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ci-pipeline-gates" ~/.claude/skills/ && echo "Installed ~/.claude/skills/ci-pipeline-gates" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/ci-pipeline-gates/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as ci-pipeline-and-gates in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, ci-pipeline-gates. Not in this download: 1 file of its source, which its SKILL.md or scripts read (which one, and why). Take it from its source.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
