triage-issue
gtrabanco / agentic-workflow

Verify an issue, persisted audit finding, or unresolved review finding against current code, classify it, and write only the contracted forge/ledger outcome. Supports independent batches and an immediate-fix review-finding route. Triggers: "triage-issue", "triage issue N", "triage this finding", "is this trigger met".

audit
audit
bastani-inc / atomic

The verifiable coding agent runtime. Define your coding agent's process in natural language with stages, checks, and approval gates instead of hoping it follows your instructions. Primitives for verifiable software factories.

Design & UI99
A
audit-pr
audit-pr
gtrabanco / agentic-workflow

Audit a whole PR against the delivery contract and return MERGE-READY or evidenced blockers with the full URL. Consumes the current review-change REVIEW-PASS receipt instead of re-running review axes; posts a SHA-bound ready comment; never edits or merges. Triggers: "audit-pr", "is this PR ready", "merge gate".

auditing-appstore-readiness
auditing-appstore-readiness
tristanmanchester / agent-skills

Audit an iOS app's source, distribution archive, runtime behaviour, and App Store Connect setup for a planned submission. Use for explicit App Store/TestFlight readiness reviews of native, React Native, or Expo apps. Distinguish verified blockers from checks that still need build, device, account, or policy evidence.

autonomous-dev
autonomous-dev
zxkane / autonomous-dev-team

Use to develop a feature or bug fix end-to-end through a TDD git-worktree workflow — interactively (developer-led) or unattended (autonomous-mode, driven by the dispatcher). Triggers on phrases like "implement issue #N", "fix this bug", "add a feature", "create a worktree", "write test cases", "push and open a PR", "check CI", "address review comments", "resolve review threads", "/q review", "/codex review", "implement this autonomously", or any partial step in the design → worktree → tests → implement → verify → review → PR → CI → E2E lifecycle. Interactive mode asks for decisions; autonomous mode makes decisions per autonomous-mode.md and posts progress comments to the GitHub issue.

Development99
A
autonomous-review
autonomous-review
zxkane / autonomous-dev-team

Use to perform an end-to-end PR review and reach an approve/request-changes verdict — including verifying acceptance criteria, running E2E tests via browser automation, resolving merge conflicts, and (when verdict passes) merging the PR. Triggers on phrases like "review this PR", "decide whether to approve and merge", "run E2E verification", "resolve merge conflicts on PR #N", or when the dispatcher hands off a PR labeled `pending-review` / `reviewing` for autonomous review. Distinct from in-flight dev-side self-review (that lives in autonomous-dev's pr-review step).

Testing & quality99
B
behavioral-a11y
behavioral-a11y
mgifford / accessibility-skills

Load this skill when writing, reviewing, or interpreting behavioral accessibility automation — tests that manipulate a rendered page (resizing the viewport, pressing real keys, capturing and comparing screenshots) rather than only inspecting static markup or a single computed accessibility tree. Covers Reflow risk (SC 1.4.10) and Focus Visible risk (SC 2.4.7) checks. Absolutely always report indicator results separately from confirmed failures. Under no circumstances treat a clean behavioral scan as WCAG conformance, or collapse `cantTell`/test-error/indicator outcomes into a single pass/fail signal.

Use when: SQA asks for a test progress or completion QA report for a ticket and version (Story, requirement sub-ticket, or BUGFIX); republish/update an existing linked report; include related/blocking tickets in report scope. NOT for: Version Quality Report or AQA automation rollup; release risk assessment (use A5 separately); importing cases (A1), plan layout (A2), or defect filing (A4). V1 zero-BE: Agent-side upsert; approximate coverage; anchor-relative subtree depth ≤ 3.

necessary-code-audit
necessary-code-audit
danhuaxiansheng / claude-code-cleanup-skills

Use for code that is used but not necessary, legacy compatibility cleanup, meaningless wrappers, defensive code removal, cleanup with no compatibility requirements, deep necessity checks, and "is this still needed?" requests; do not use it as a pure unused/dead-code proof tool.

Generate and validate API tests based on the real OpenAPI, route implementation, and existing tests. Use when the user asks to test endpoints, add integration tests, validate the API contract, generate regression cases, or troubleshoot API compatibility; distinguish the authorization for "generating tests" from "executing requests", do not guess status codes, response structures, or SLAs, and do not send write requests in unconfirmed environments.

audit-docs
audit-docs
gtrabanco / agentic-workflow

Audit cross-document coherence: docs ↔ roadmap ↔ code ↔ fix index ↔ issues. Finds drift — features in docs/ not in the roadmap (or vice versa), fix-index entries already merged/closed, broken documentation-map links, dependency cycles, artifacts in the wrong language, naming-convention violations — and reports them ranked by severity, fixing only low-risk items on request. Model-agnostic: the skill inherits whatever model and effort your agent session is already using. Triggers: "check doc consistency", "are the docs in sync", "audit the docs", "doc coherence review", "did the docs drift", "validate the roadmap".

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
