cleaning-redundant-ci

name	cleaning-redundant-ci
description	Sweeps a fleet repo (or every fleet repo) for redundant CI surface — orphan workflow YAML files (lint.yml / check.yml / type.yml / test.yml that the unified ci.yml replaced), GitHub-Dependabot auto-fix PRs that the fleet handles via /updating-security, and stale workflow run history in the Actions sidebar. Deletes the YAML files, disables Dependabot automated-security-fixes via gh api, and reports anything that needs a manual UI toggle. Once-and-never-again sweep — meant to leave a repo clean.

cleaning-redundant-ci

Audit + clean redundant CI surface on a Socket fleet repo. Three target classes:

1. Orphan workflow YAML files — lint.yml, check.yml, type.yml, test.yml. The fleet consolidated those into the shared ci.yml (via SocketDev/socket-registry/.github/workflows/ci.yml) long ago. Any per-repo file with those names is a leftover from pre-consolidation days. Delete them.

2. GitHub-Dependabot automated security PRs — the fleet pattern is to handle vulnerability fixes via /updating-security (pnpm overrides: for transitive deps), not via auto-PRs from Dependabot. The dependabot.yml no-op file (open-pull-requests-limit: 0) suppresses version-update PRs but does NOT suppress security PRs — those flow from a separate repo-settings toggle (automated-security-fixes). Disable via gh api -X DELETE /repos/{owner}/{repo}/automated-security-fixes.

3. Stale workflow run history — when a workflow YAML gets deleted, the runs stay listed in the Actions sidebar forever (the workflow appears as a name with no associated file). Delete the workflow record via gh api /repos/{owner}/{repo}/actions/workflows/{id} -X DELETE to remove the sidebar entry.

When to use

• Onboarding a new fleet repo — sweep once on first integration to clear any pre-fleet CI baggage.
• After a CI consolidation cascade — when the fleet retires a workflow shape (e.g. the lint/check/type/test → unified ci.yml migration), run this skill on every fleet repo to clean up the per-repo leftovers.
• Periodic fleet-wide health check — run quarterly to catch drift (someone adds a per-repo lint.yml to scratch an itch, forgetting the unified ci.yml already covers it).

What it does NOT do

• Touch the dependabot.yml file. That file MUST exist (GitHub refuses to fully disable Dependabot without it) and the fleet convention is to ship it pre-configured with open-pull-requests-limit: 0. The skill leaves the file alone; only the automated-security-fixes toggle is acted on.
• Touch SocketDev/workflows. Don't edit org-level required workflows from this skill — the org config is the source of truth for what runs cross-repo, and silent edits are unsafe.
• Delete legitimate per-repo workflows. socket-btm's per-binary build dispatchers (curl.yml, lief.yml, etc.), ultrathink's build-*.yml, socket-packageurl-js's pages.yml /valtown.yml, socket-registry's _local-not-for-reuse-*.yml dogfood copies — all stay. The skill only matches the four canonical orphan names.

Phases

Phase 1 — Inventory

# Orphan YAML files
ls .github/workflows/ | grep -E '^(lint|check|type|test)\.ya?ml$'

# Workflow records (live + stale)
gh api "repos/{owner}/{repo}/actions/workflows" --paginate \
  --jq '.workflows[] | "\(.id)\t\(.state)\t\(.name)\t\(.path)"'

# Dependabot automated-security-fixes state
gh api "repos/{owner}/{repo}/automated-security-fixes" --jq .enabled

Categorise each finding:

• delete-file: orphan YAML on disk
• delete-record: workflow record whose .path no longer exists in the repo OR whose name matches the orphan pattern
• toggle-off: automated-security-fixes: true

Phase 2 — File deletions (commit + push)

git rm .github/workflows/{lint,check,type,test}.yml 2>/dev/null
git commit -m "chore(ci): remove orphan {lint,check,type,test} workflows — consolidated into ci.yml"

One commit per repo, conventional-commit subject. Push directly to main per fleet policy (or fall back to PR if branch protection requires).

Phase 3 — Workflow record deletions (gh api)

For each delete-record finding:

gh api -X DELETE "repos/{owner}/{repo}/actions/workflows/{id}"

GitHub returns 204 on success. The record disappears from the Actions sidebar. Runs associated with the workflow remain in their own URLs but stop showing in the per-workflow filter.

Skip workflow records that match dynamic/dependabot/... — those are GitHub-managed and can't be deleted via API. They'll stop appearing on their own once Dependabot has nothing to do (after Phase 4).

Phase 4 — Disable Dependabot automated-security-fixes

gh api -X DELETE "repos/{owner}/{repo}/automated-security-fixes"

204 = disabled. Going forward, security advisories are visible in the Security tab (via the vulnerability-alerts setting, which stays on) but won't open auto-PRs. The fleet's /updating-security skill is the canonical path for resolving them.

Phase 5 — Report

For each repo: list what was deleted, what was disabled, and what needs manual UI action (rare — most things this skill touches are API-actionable).

Fleet-wide invocation

# One repo
/cleaning-redundant-ci socket-foo

# All fleet repos (reads template/.claude/skills/cascading-fleet/lib/fleet-repos.json)
/cleaning-redundant-ci --all

The fleet-roster path is the canonical list — same file the cascade mechanism uses. Don't hard-code a repo list inside this skill.

Safety

• Read-only inventory first. Print findings before any deletion.
• Per-repo confirmation in interactive mode; --yes to skip.
• Direct push to main, fall back to PR per fleet policy. Never force-push.
• Never edit dependabot.yml — only the automated-security-fixes toggle. The .yml is structurally required.
• Never touch SocketDev/workflows. Org-required workflows are out of scope.

Why a skill, not a hook

This is operator-invoked maintenance, not edit-time enforcement. Hooks are wrong shape: there's no gh commit or gh push event that should trigger a fleet-wide CI audit. Skills are user-callable, run on demand, and produce a one-shot report.
