> cobra

You are an expert in Cobra, the most popular Go library for building modern CLI applications. You help developers create command-line tools with subcommands, flags, argument validation, shell completions, and help generation — powering CLIs like kubectl, Hugo, GitHub CLI, and Docker.

> act

Run GitHub Actions locally with act. Use when a user asks to test GitHub Actions workflows locally, debug CI pipelines without pushing, or run workflows offline.

> dvc

Data Version Control for ML projects. Track large datasets and models alongside Git, build reproducible ML pipelines, and run experiments with metric comparison. Works with any storage backend including S3, GCS, Azure, and local filesystems.

> webhook-processor

Build and configure webhook processing systems with retry logic, signature verification, and dead letter queues. Use when you need to receive, validate, and reliably process incoming webhooks from payment providers, version control platforms, or third-party APIs. Trigger words: webhook, callback URL, event handler, retry, idempotency, payload processing.

> security-ownership-map

Analyze git repositories to build a security ownership topology (people-to-file), compute bus factor and sensitive-code ownership, and export CSV/JSON for graph databases and visualization. Trigger only when the user explicitly wants a security-oriented ownership or bus-factor analysis grounded in git history (for example: orphaned sensitive code, security maintainers, CODEOWNERS reality checks for risk, sensitive hotspots, or ownership clusters). Do not trigger for general maintainer lists or n

> gh-fix-ci

Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions; use `gh` to inspect checks and logs, summarize failure context, draft a fix plan, and implement only after explicit approval. Treat external providers (for example Buildkite) as out of scope and report only the details URL.

> ai-eval-ci

Run AI agent and LLM evaluations in CI/CD pipelines — automated quality gates that fail the build when AI output quality drops. Use when someone asks to "test my AI agent", "add evals to CI", "catch prompt regressions", "compare models", "evaluate LLM output quality", "set up AI quality gates", or "benchmark my agent before deploying". Covers eval frameworks (Cobalt, Promptfoo, Braintrust), LLM-as-judge scoring, threshold-based assertions, and GitHub Actions integration.

> husky

Run scripts on Git hooks with Husky. Use when a user asks to run linters before commit, validate commit messages, run tests before push, or set up Git hooks for a team.

> skill-installer

Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).

> lefthook

Fast Git hooks manager written in Go. Use when a user asks to set up Git hooks without Node.js dependency, run parallel pre-commit checks, or find a faster alternative to Husky.

> github-actions

Write and modify GitHub Actions workflows and custom actions. Covers CI/CD, workflow triggers, jobs, steps, secrets, runners, matrix builds, caching, artifacts, environments, and reusable workflows.

> linear

Manage projects and issues with Linear. Use when a user asks to set up Linear workspaces, create issues and projects, automate workflows, build Linear integrations, sync issues with GitHub, manage sprints and cycles, set up triage processes, build custom views, use Linear's GraphQL API, create webhooks, automate issue transitions, or build tools on top of Linear. Covers workspace configuration, team workflows, API automation, and integration patterns.

> koyeb

Expert guidance for Koyeb, the serverless cloud platform for deploying full-stack applications, APIs, and workers globally with automatic scaling, built-in CI/CD, and edge networking. Helps developers deploy applications from Git or Docker with zero-downtime deployments and pay-per-use pricing.

> neon-branching

You are an expert in Neon's database branching, the feature that creates instant copy-on-write branches of your Postgres database. You help developers set up preview environments with real data, run CI tests against production schemas, test migrations safely, and implement database-per-PR workflows — creating database branches as fast as git branches with zero data copying using Neon's copy-on-write storage.

> git-commit-pro

Write well-structured git commit messages following the Conventional Commits standard. Use when a user asks to commit changes, write a commit message, stage and commit, improve a commit message, or follow commit conventions. Analyzes diffs to produce accurate, meaningful commit messages.

> bitbucket

Manage repositories, pipelines, and code review with Bitbucket Cloud. Use when a user asks to set up Bitbucket repositories, configure Bitbucket Pipelines for CI/CD, manage pull requests, set up branch permissions, use Bitbucket REST API 2.0, create webhooks, manage deployment environments, set up code review workflows, integrate with Jira, configure merge checks, or automate repository operations. Covers repository management, CI/CD pipelines, code review, deployments, and Atlassian ecosystem i

> changelog-generator

Generate release notes and changelogs from git commits, feature lists, or project updates. Use when a user asks to generate a changelog, create release notes, summarize recent changes, draft a CHANGELOG entry, or prepare release documentation from git history.

> argocd

Argo CD for GitOps continuous delivery on Kubernetes. Use when the user needs to define applications declaratively, sync Kubernetes manifests from Git repositories, manage sync policies, and implement progressive delivery workflows.

> mkdocs

Build documentation sites with MkDocs and Material for MkDocs. Use when a user asks to create project documentation, configure MkDocs themes, add search and navigation, deploy docs to GitHub Pages, or customize Markdown extensions.

> mastering-github-cli

GitHub CLI (gh) command reference for repository search, code discovery, CI/CD monitoring, workflow authoring, and automation. Triggers on "gh" commands, "github cli", searching repos for files/directories (.skilz, .cursor, .codex, Dockerfile), monitoring GitHub Actions workflows, checking PR CI status, downloading artifacts, creating PRs/issues/repos from command line, triggering workflows, forking repos, batch operations, "write a workflow", "github actions", "CI/CD pipeline", "workflow yaml",
