Skills by category

Coding

• [Accessibility Audit](skills/accessibility-audit/SKILL.md) — Runs a full WCAG 2.2 accessibility audit of an interface - keyboard, screen reader, contrast and zoom, forms, and media, in a fixed pass order - and delivers a severity-triaged findings table with concrete fixes.
• [Agent Orchestration](skills/agent-orchestration/SKILL.md) — Designs reliable multi-agent LLM systems - choosing a topology, writing handoff contracts between agents, deciding what runs in parallel vs series, and setting context, retry, and cost budgets that stop runaway loops.
• [Alert Tuning](skills/alert-tuning/SKILL.md) — Reduces alert noise by making alerts actionable, symptom-based, and tied to SLOs.
• [API Client Generator](skills/api-client-generator/SKILL.md) — Generates a typed API client from an OpenAPI/Swagger spec, with a hand-controlled transport wrapper for timeouts, auth, and typed errors.
• [REST API Design](skills/api-design/SKILL.md) — Designs REST API surfaces - resource naming, HTTP method and status-code semantics, error shapes, pagination, and filtering - and delivers an endpoint spec a consumer can build against without asking questions.
• [API Versioning Strategist](skills/api-versioning-strategist/SKILL.md) — Produces an API version scheme (date-pinned header or URI), a breaking-vs-additive change policy, and a published deprecation/sunset timeline with translation shims.
• [App Store Release Prep](skills/app-store-release-prep/SKILL.md) — Produce a reproducible signing, versioning, and store-declaration pipeline so an iOS or Android build passes App Store Connect / Play Console submission.
• [Build on Agent-Native](skills/build-on-agent-native/SKILL.md) — Build an application on Builder.io's open-source Agent-Native framework (@agent-native/core) - the model where the agent acts inside the app as a first-class peer to the UI, sharing one set of actions and one database with the interface.
• [Business Rule Extractor](skills/business-rule-extractor/SKILL.md) — Produces a documented inventory of the implicit business rules, edge cases, and bug-as-feature behaviors that tangled code encodes, with real input-to-output examples, so a rewrite preserves behavior.
• [Caching Strategy](skills/caching-strategy/SKILL.md) — Designs multi-layer caching - CDN, application, and database - choosing the pattern, TTL, and invalidation plan per data type, and produces a cache-decision table plus stampede protection.
• [Changelog Generator](skills/changelog-generator/SKILL.md) — Generate or update a repository CHANGELOG.md in Keep a Changelog format from git history - grouping commits since the last tag into Added/Changed/Deprecated/Removed/Fixed/Security, rewriting them as user-facing entries, and recommending the semantic version bump.
• [Characterization Test Writer](skills/characterization-test-writer/SKILL.md) — Writes pinning and characterization tests that lock in the current behavior of untested legacy code - bugs included - before a refactor, so any later behavior change trips an alarm.
• [Circuit Breaker Builder](skills/circuit-breaker-builder/SKILL.md) — Wraps flaky upstream dependencies in circuit breakers, aggressive timeouts, and per-dependency bulkheads so a slow or failing service degrades gracefully instead of cascading into a full outage.
• [Code Review Checklist](skills/code-review-checklist/SKILL.md) — Run a systematic multi-pass code review - correctness, design, security, performance, tests - and report findings ordered by severity with concrete, respectful suggestions.
• [Contract Test Writer](skills/contract-test-writer/SKILL.md) — Writes consumer-driven contract tests at service and API boundaries - Pact consumer tests, provider verification, broker publishing, and can-i-deploy gates - so an incompatible change fails a build instead of breaking integrations in production.
• [Coverage Gap Finder](skills/coverage-gap-finder/SKILL.md) — Produces a risk-ranked list of untested critical paths and branches from a real branch-coverage report crossed with git churn, naming the specific missing cases and the smallest test that buys the most safety.
• [Database Schema Designer](skills/database-schema/SKILL.md) — Designs normalized, constrained, migration-friendly relational schemas - entity modeling, key and type selection, indexes derived from real query patterns, and safe forward/rollback migrations.
• [Dead Code Eliminator](skills/dead-code-eliminator/SKILL.md) — Proves code is unreachable with converging evidence, then removes it and its tests, fixtures, and flags in reversible slices without breaking dynamic callers.
• [Dependency Risk Audit](skills/dependency-risk-audit/SKILL.md) — Audits third-party dependencies for exploitable CVEs, abandonment, license exposure, and supply-chain hygiene, and delivers a ranked findings report with a remediation order.
• [Docker Compose Wizard](skills/docker-compose-wizard/SKILL.md) — Produces production-minded docker-compose configurations - pinned images, healthchecks with real intervals, health-gated startup ordering, named volumes, explicit networks, and env-file secrets - plus the matching .env.example.
• [E2E Scenario Author](skills/e2e-scenario-author/SKILL.md) — Converts an acceptance criterion or user story into one maintainable Playwright or Cypress end-to-end test that reads like the journey it covers.
• [Environment Doctor](skills/env-doctor/SKILL.md) — Diagnose and fix a broken local development environment methodically - reproduce the failure, fingerprint runtime, package manager, OS and arch, check version files and PATH shadowing, lockfile drift, missing env vars (without printing secrets), port conflicts, stale caches, native-module and Apple Silicon arch mismatches, and Docker context - then apply the smallest fix and leave a reproducible setup note.
• [Error Budget Policy](skills/error-budget-policy/SKILL.md) — Defines and applies an SLO error-budget policy that gates feature work versus reliability work based on remaining budget.
• [Error Handling](skills/error-handling/SKILL.md) — Designs typed, observable, recoverable error handling - an explicit taxonomy of retryable vs terminal failures, Result types at boundaries, single-point logging, and retry policies with real backoff numbers.
• [Feature Flags](skills/feature-flags/SKILL.md) — Designs feature-flag systems and lifecycle policy - flag taxonomy (release, ops/kill-switch, experiment, permission), percentage rollouts with stable bucketing, safe defaults, and mandatory removal deadlines so flags don't rot into dead code.
• [Flaky Test Detangler](skills/flaky-test-detangler/SKILL.md) — Root-causes intermittently failing tests and eliminates the hidden dependency at its source instead of retrying around it.
• [Flutter Widget Architect](skills/flutter-widget-architect/SKILL.md) — Architects Flutter widget trees and Riverpod or Bloc state so rebuilds are scoped, build() stays pure, and const widgets skip recomposition.
• [Framework Upgrader](skills/framework-upgrader/SKILL.md) — Drives a major-version framework bump as a sequence of small, reversible, CI-gated PRs using official codemods and changelog diffing while keeping the app green.
• [Git Commit Writer](skills/git-commit-writer/SKILL.md) — Write commit messages from a staged diff in Conventional Commits 1.0.0 format - correct type and scope, ! and BREAKING CHANGE footers, GitHub closing keywords, and a body that explains why - and split mixed changes into separately revertable commits.
• [GitHub Actions](skills/github-actions/SKILL.md) — Designs and hardens GitHub Actions CI/CD - pipelines that hit a sub-10-minute PR feedback budget through caching and parallelism, with least-privilege security and safe deploy gates.
• [GraphQL Schema](skills/graphql-schema/SKILL.md) — Designs GraphQL schemas and resolvers that scale - domain-modeled types, Relay pagination, DataLoader batching to kill N+1, mutation payloads with typed user errors, and depth/complexity limits that stop abusive queries.
• [Idempotency Enforcer](skills/idempotency-enforcer/SKILL.md) — Designs client-supplied idempotency keys, deduplication storage, and replay semantics so at-least-once delivery and client retries return the first result instead of double-charging or double-shipping.
• [Jetpack Compose Builder](skills/jetpack-compose-builder/SKILL.md) — Builds Android Jetpack Compose UI with hoisted state, unidirectional data flow, and recomposition-safe patterns backed by measured stability rules.
• [Kubernetes Basics](skills/kubernetes-basics/SKILL.md) — Writes production-ready Kubernetes manifests - Deployments with correct resource requests/limits, readiness/liveness/startup probes, PodDisruptionBudgets, safe rollouts, and graceful shutdown.
• [Language Version Migrator](skills/language-version-migrator/SKILL.md) — Ports a codebase across a breaking language or runtime version with compatibility shims, batched automated transforms, dual-runtime CI, and old-vs-new output diffing, ending in a flag-flip cutover with a rollback rule.
• [LLM Evaluation](skills/llm-evaluation/SKILL.md) — Builds evaluation harnesses for LLM products - golden datasets, deterministic checks, calibrated LLM-as-judge rubrics, and CI regression gates that turn "seems good" into a tracked number.
• [Load Testing](skills/load-testing/SKILL.md) — Designs and interprets load tests - smoke, load, stress, soak, and spike - with realistic ramp profiles, percentile-based pass/fail thresholds, and a bottleneck-reading procedure, producing a runnable test plan.
• [MCP Server Builder](skills/mcp-builder/SKILL.md) — Design and build Model Context Protocol servers that models use correctly - choosing stdio vs stateless Streamable HTTP while still serving 2025-era clients, shaping a few task-level tools with clear descriptions, JSON Schema inputs and honest annotations, bounding and paginating output, returning recoverable errors as isError results, securing remote servers with OAuth 2.1, and testing with the MCP Inspector.
• [Microservices Design](skills/microservices/SKILL.md) — Designs microservice architectures - service boundaries from business capabilities and team ownership, sync vs async communication choices, saga and outbox patterns for consistency, and resilience defaults - producing a boundary map with an extraction verdict per candidate service.
