01

acquire-codebase-knowledge

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like \"map this codebase\", \"document this architecture\", \"onboard me to this repo\", or \"create codebase docs\". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

v1.0.2draft
02

agent-governance

Use this skill when building AI agents that call external tools, implementing policy-based access controls, adding semantic intent classification, creating trust scoring systems, building audit trails, or enforcing rate limits and content filters on agents.

v1.1.1draft
03

agent-instructions

Use when creating or updating agent instruction files (AGENTS.md for Pi, copilot-instructions.md for Copilot, per-path guides, or AGENTS.md router) — especially when instruction files are too long, generic, or stale, or when agents repeatedly make the same avoidable mistakes.

v2.0.1draft
04

agent-supply-chain

Use this skill when generating SHA-256 integrity manifests for agent plugins, verifying that installed plugins match their manifests, detecting tampered files, auditing dependency pinning, or building provenance chains for plugin promotion.

v2.0.1draft
05

agentic-eval

Use when designing or implementing an evaluation loop for AI agent outputs — reflection loops, evaluator-optimizer pipelines, LLM-as-judge scoring, or rubric-based iteration. Not when running an existing test suite or reviewing a completed artifact without iterating.

v2.0.1draft
06

api-smoke-validation

Use when running quick, repeatable API smoke tests after changes with hurl, including auth, status-code, response-shape, endpoint sanity, and pre-integration health checks.

v1.1.1draft
07

ast-grep

Use when you need ast-grep structural search, linting, or safe codemod rewrites, especially for requests that mention ast-grep, sg, codemod, rule files, or syntax-aware edits instead of plain-text search.

v2.0.1draft
08

astro-seo

Audit and improve SEO for Astro sites, including metadata, structured data, sitemaps, indexing, Open Graph images, schema endpoints, and related search visibility setup.

v1.3.1stable

v1.3.1stable
12

cloudflare-d1-migrations

Create, inspect, apply, baseline, import, or recover Cloudflare D1 schema migrations across local, preview, and remote databases. Use when Wrangler D1 migration state or schema drift is the main risk.

Run and troubleshoot repository code generation after detecting the generator contract. Use when schema, query, spec, or template inputs changed, or generated output may be stale.

v1.4.1stable
15

code-intelligence

Use when navigating or refactoring code — choosing between LSP, rg, or semantic search tools; an LSP call returns empty and you need to know if it failed; or a tool substitution needs disclosure.

v1.1.1draft
16

code-tour

Use when asked to create a .tour walkthrough — onboarding, PR review, RCA, architecture, or any persona-targeted step-by-step code narrative. Not for codebase exploration without a .tour file output.

v1.0.2draft
17

configuration-env

Configure applications safely through environment variables, .env files, and repo-owned runtime config such as Wrangler bindings. Use for startup failures, environment drift, or deployment bootstrap.

v1.3.1stable
18

context-map

Use when the user explicitly wants a pre-edit scoping pass — mapping candidate files, tests, and reference patterns before implementation. Not for general multi-file tasks unless the user asks "what files are involved" or requests a context map.

v2.0.1draft
19

database-migrations

Create, apply, inspect, and recover database schema migrations after detecting the repository's migration contract. Use when changing persistent schema, adding indexes/constraints, or troubleshooting migration state.

v1.4.1stable
20

doc-coauthoring

Use when user wants to write, refactor, or expand documentation through iterative co-authoring with reader feedback — README, guides, API docs, runbooks, specification documents. Not for solo writing, readability audits, or metadata review (use writing-and-editing for those).

v1.0.2draft
21

docker-compose-dev

Run a service stack locally using Docker Compose for prod-like development (e.g. PostgreSQL + app). Use when you need a real DB backend, multi-service integration, or want to reproduce production-like behavior locally.

v2.0.1draft
23

finishing-a-development-branch

Use when implementation work is complete and you need to decide how to integrate the branch — merging locally, creating a PR, keeping the branch, or discarding the work.

v3.0.0stable
24

git-signing-troubleshoot

Use when commits, tags, or pushes are blocked by GPG or SSH signing failures — including 1Password op-ssh-sign errors, failed to fill whole buffer, or misleading op whoami output, not when the main task is branch integration, PR handling, or secret-scan triage.

v1.0.2draft
25

git-worktrees

Set up and manage isolated git worktrees for parallel tasks and agent lanes, and configure or operate Worktrunk (wt) for worktree lifecycle, hooks, LLM commits, and parallel agent workflows.

v3.0.0draft
29

github-presence

Audit and improve GitHub profile, organization, and repository presentation. Use for profile READMEs, pinned repositories, README quality, community health files, templates, and repo metadata.

v1.3.1stable
30

go-build-and-test

Diagnose Go build failures, toolchain mismatches, and CI-parity problems — GOROOT/GOTOOLDIR overrides, govulncheck stdlib findings, or TempDir race flakes. Use when go build or CI fails for environmental reasons, not when individual tests fail on logic or coverage (use testing-workflows for that).

v1.1.1draft
31

go-cli-development

Develop, structure, and release Go CLI tools. Use when building a new Go CLI, adding subcommands or flags, wiring config, formatting output, setting up goreleaser + Homebrew distribution, or debugging CLI-specific behavior — not for build failures or test debugging.

32

go-docker-builds

Containerize Go services with production-ready multi-stage Docker builds. Use when writing or debugging a Dockerfile for a Go service, setting up static compilation for scratch/distroless images, adding health checks, or wiring image builds into CI — not for Docker Compose local dev stacks or non-Go Dockerfiles.

v1.1.1stable
33

go-error-patterns

Use when Go error-handling design or function-type mismatches surface — including `func(string) error` vs concrete constructors, package-local type aliases, or concrete-vs-interface error choices, but not when the immediate task is a build or test failure.

v1.1.1draft
34

goreleaser-release-pipeline

Use when setting up, debugging, or fixing a GoReleaser v2 release pipeline — especially Release Please tag issues, missing release assets, or publish jobs that fail after a release is created, not when the main task is generic CI triage or PR handling.

v1.0.2draft
35

graphify

Build and query persistent Graphify knowledge graphs from code, documents, papers, images, or video. Use when the user asks to graphify a corpus, needs graph-based mapping, path, or community analysis, invokes Graphify commands, or asks a corpus question when graphify-out/ already exists.

v0.2.1experimental
36

grill-me

Use when the user wants to be interviewed or stress-tested about a plan, design, or decision, including explicit requests to 'grill me'. If they also mention CONTEXT.md, ADRs, or a domain glossary, use the documentation mode; otherwise keep the session pure interrogation and do not create docs.

v1.0.2draft
44

neovim-plugin-development

Develop, test, and release Neovim Lua plugins. Use when building a new Neovim plugin, adding features to an existing plugin, setting up CI with GitHub Actions, writing plenary tests, generating documentation, or configuring release automation — not for editing user-level Neovim config.

v1.1.1stable
45

observability-metrics

review-comment-resolution

Apply pull request review feedback by assessing comments, fixing valid concerns, pushing the branch, and waiting for checks. Use when reviewer feedback must be carried through to completion, not just reviewed.

v1.3.1stable
51

rpi-workflow

Apply a Research → Plan → Implement → Validate workflow for multi-phase work that benefits from explicit phase boundaries. Use when the task is complex, spans many files, or needs durable progress artifacts — not for small fixes, single-file edits, or narrow specialist workflows.

v1.5.1stable
52

sam-cloudformation

Use when AWS SAM templates, CloudFormation stacks, or SAM deploys fail on YAML, transforms, resource wiring, or rollback state, or when the deploy caller gets AWS sts:AssumeRole or sts:AssumeRoleWithWebIdentity AccessDenied — not when the Lambda binary itself or Terraform-owned infrastructure is the primary blocker.

v3.0.0draft
53

schema-boundary-typing

Introduce or refine runtime schema validation at untrusted boundaries so static TypeScript types stay truthful.

v1.3.1stable
54

secret-scan-triage

Use when secret scanning with gitleaks reports findings that need fast triage, containment, and false-positive adjudication before code changes or merges continue.

v1.0.2draft
55

v2.0.1stable
57

skill-creator

Build, upgrade, or standardise a specific skill package in the current catalog. Use when adding a skill directory, reconciling its authoring contract, improving metadata/examples/evals, or tightening trigger boundaries — not for one-off prompt advice.

terraform-skill

Use when writing, reviewing, or debugging Terraform/OpenTofu — modules, tests, CI/CD, security scans, or state operations.

v1.1.1draft
61

test-driven-development

Use when the user explicitly asks for test-driven development (TDD), a red-green-refactor cycle, or test-first implementation — not for general feature work, bug fixes, or refactoring unless TDD discipline is specifically requested.

v1.1.1draft
62

testing-workflows

Write, run, and debug Go tests — unit and integration — including generator refresh when stale generated code causes failures. Use when adding test coverage or debugging test failures in domain logic, repositories, or handlers. For build failures, toolchain issues, or CI-parity problems, use go-build-and-test instead.

v1.3.1stable
63

to-issues

Use when the user wants to turn a plan, spec, PRD, or approved idea into independently grabbable issue-tracker slices. Not when the work still needs a PRD, repository discovery, or a generic handoff artifact.

v2.0.1draft
64

to-prd

Use when the user wants a PRD synthesized from current repository and conversation context, especially for issue-tracker handoff. Not when doc-coauthoring, workflow-contracts, or codebase discovery is the better fit.

type-test-authoring

Write compile-time type tests that protect public TypeScript APIs, inference behavior, and negative cases.

v1.3.1stable
68

typescript-any-eliminator

Use when TypeScript source contains explicit `any` in application code, shared helpers, DTOs, or API layers that should be narrowed without changing runtime behavior — or when a reviewer or lint rule flags unsafe `any` usage.

69

verification-before-completion

Use when about to claim work is complete, tests pass, a bug is fixed, or a build succeeds.

v2.0.1stable
70

workflow-contracts

Use when a task needs a durable handoff artifact for planning, review, or execution in agent-driven workflows — not just a chat summary.

v2.0.1draft
71

writing-and-editing

Draft structured documents, audit prose readability, and review short audience-facing metadata strings — solo writing quality work. Use when the primary task is writing, editing, or copy quality, not iterative co-authoring with reader feedback (use doc-coauthoring for that).

v1.3.1stable
