What it does

Bot-paired fast-lane cycle for coherent-arc internal PRs (one closable bead or small-epic slice): claim → test → impl → pre-push → push → squash auto-merge → close.

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.

51> **Lane choice:** use this skill for **coherent-arc internal PRs** — one closable bead, or one small-epic slice (≤5 child beads of the same surface), with paired tests. The PR is the *atomic-revert unit*: bundle scenarios that ship-or-revert together; split scenarios with independent rollback. For fork-based OSS contributions, use the /pr-* family (pr-research, plan, pr-implement, etc.; tier contribute). For large epics (15+ child beads) or multi-wave work, use /crank. See CLAUDE.md ## Workflow for the canonical unit-of-PR rule.

53Capture of the discipline that landed 8/9 internal PRs in the 2026-05-18 session at 19.5-min median time-to-merge. Five named failure modes (F1–F5); four closed mechanically. The full rationale lives in [docs/learnings/2026-05-18-xp-bdd-tdd-workflow-synthesis.md](https://github.com/boshu2/agentops/blob/main/docs/learnings/2026-05-18-xp-bdd-tdd-workflow-synthesis.md).

55## Overview / When to Use
56
57Run this skill at the START of each PR you intend to ship to your own main branch. The skill enforces the cycle as a sequence; each step has a clear done-state and gate.
58
59**Pair partner:** claude-review (GitHub App workflow at .github/workflows/claude.yml) auto-fires on pull_request: opened/synchronize. No @claude mention is required. Operator does the edits; bot does the review check.

61## The 9-step cycle
62
631. **Claim.** bd ready → pick the highest-severity unblocked item, OR read .agents/rpi/next-work.jsonl for harvested follow-ups. **bd update <id> --claim** atomically.
642. **Branch off fresh main.** git checkout main && git pull --rebase. Then git checkout -b <type>/<slug>-<bead-id>. NEVER stack off a sibling branch; auto-merge handles serialization via update-branch.
653. **Write the FIRST FAILING TEST.** BDD scenario (Gherkin) for behavior; unit test for invariants. The test must fail for the *right reason* (asserting expected behavior, not just "doesn't crash"). See [references/test-shape.md](references/test-shape.md).
664. **Minimal implementation.** Smallest code change that makes the test green. Resist scope creep. Refer to the project's standards (.claude/rules/{go,python}.md).
675. **scripts/ship.sh** (recommended) — auto-detects inventory-touching changes and runs the regen sweep (sync-skill-counts, codex-hashes, domain-map, context-map, registry, sync-hooks) preemptively. **This is the mechanical fix for anti-pattern #1** — removes the operator's choice to skip the rule. CI (.github/workflows/validate.yml) is the sole authoritative push gate per docs/contracts/local-pre-push-gate-retirement.md (soc-g2r9, PR #357); the previous scripts/pre-push-gate.sh local mirror was retired because per-incident drift cost dominated the per-push wait. For per-tool sanity before push, run only what your diff touches: cd cli && make test, bats tests/scripts/<file>.bats, scripts/regen-codex-hashes.sh. If a pre-existing blocker appears in unchanged-from-base content (visible in CI now), **file an atomic side-quest fix PR first** — don't bundle. See [references/anti-patterns.md](references/anti-patterns.md). **For PRs that change gate/validator/CI behavior**: capture the targeted output line and include it verbatim in the PR body as Evidence:; the validate-pr-evidence-claims CI job (scripts/verify-gate-claim.sh, soc-o5kq + soc-eqjd) verifies each Evidence line against the workflow run's logs and blocks the PR if any claim is absent (mechanical enforcement of anti-pattern #7).

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.

≈220
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
7,805
on trigger
The instruction body and 5 supporting files, read only when the skill fires.
4.0%
of a 200k window
Ten skills this size would take about 40% of the window before you open a file.
050k100k150k200k context window

8k 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 6 of the 7 files in its source folder; the list here names 6 files, 34.6 kB on disk. Mostly text — the instructions the model reads — with 1 script 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.md12.7 kB
  • references/anti-patterns.md9.3 kB
  • references/examples.md4.1 kB
  • references/gh-merge-chain.md2.2 kB
  • references/test-shape.md3.8 kB
  • scripts/validate.sh2.5 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 1 script beside the text, so the download is 6 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 Apache-2.0 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.

# /ship-loop — Bot-paired fast lane PR cycle · 8k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/ship-loop-bot-paired-fast-lane-pr-cycle/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ship-loop-bot-paired-fast-lane-pr-cycle" ] && { [ ! -e .claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle ] || { mv .claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ship-loop-bot-paired-fast-lane-pr-cycle" .claude/skills/ && echo "Installed .claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle"

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/ship-loop-bot-paired-fast-lane-pr-cycle/ 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/ship-loop-bot-paired-fast-lane-pr-cycle/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ship-loop-bot-paired-fast-lane-pr-cycle" ] && { [ ! -e ~/.claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle ] || { mv ~/.claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ship-loop-bot-paired-fast-lane-pr-cycle" ~/.claude/skills/ && echo "Installed ~/.claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/ship-loop-bot-paired-fast-lane-pr-cycle/ 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 ship-loop in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, ship-loop-bot-paired-fast-lane-pr-cycle. 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.
