SkillCatch
CAClaude Academy GuideClaude Academy course matcher for product questions
Anthropic product skill. Recommends academy.claude.com courses — never invent them. Idle when the user wants the task done, not a tutorial.
AAAlgorithmic ArtSeeded p5.js generative-art skill
Idle unless someone asks for generative art. Original work only; not a copy-an-artist skill.
ABAnthropic Brand GuidelinesAnthropic brand colors and type for artifacts
This is Anthropic's look — Poppins, Lora, #d97757 — not “your brand.”
CDCanvas DesignPoster and static visual design in PNG/PDF
Static PNG/PDF posters. Not product UI. Will sit idle unless someone asks for a piece.
CAClaude APIClaude API / Anthropic SDK reference before you guess
Vendor + broad-trigger Catch: fires on almost any LLM-shaped task and steers to Anthropic. Skip when another provider is the job.
DCDoc CoauthoringStructured loop for co-authoring specs and docs
Anthropic’s three-stage writing loop. Never-fire if the agent just writes the doc. Distinct from Sentry’s copy in getsentry/skills.
FDFrontend DesignIntentional visual direction so UI is not template-default
Aesthetic direction, not a component library. Idle unless someone is actually choosing a look.
MBMCP BuilderHow to build MCP servers in Python or TypeScript
How to *build* an MCP server. Not how to wire one that already exists.
SCSkill CreatorCreate, edit, eval, and tune agent skills
Meta-skill for authoring and eval-ing skills. Idle unless you are writing a skill.
SGSlack GIF CreatorAnimated GIFs sized and timed for Slack
Will sit idle unless someone actually asks for a Slack GIF.
TFTheme FactoryTen preset themes, or a new one, for artifacts
Ten palettes for artifacts. Idle unless someone wants a theme applied.
WAWeb Artifacts BuilderMulti-component claude.ai HTML artifacts (React + shadcn)
Locked to claude.ai HTML artifacts (React + Tailwind + shadcn bundle). Not a general web app skill.
WTWebapp TestingPlaywright toolkit for local webapp UI and logs
Playwright against localhost. Needs a running app; a screenshot is not a test plan.
DPDispatching Parallel AgentsSplit independent work across parallel agents
Only when 2+ tasks share no state. Sequential work is a false fire.
EPExecuting PlansRun a written plan in a separate session with checkpoints
Separate session, written plan, checkpoints. Not for writing the plan.
FAFinishing a Development BranchIntegrate a finished, tested branch
Tests already pass. This decides how to land it — not whether it works.
RCReceiving Code ReviewVerify review feedback before you implement it
Verify feedback before implementing. Rubber-stamping is the failure mode.
RCRequesting Code ReviewAsk for review after a real feature or before merge
After a real feature or before merge. Not a substitute for tests.
SDSubagent-Driven DevelopmentExecute a plan with independent subagents in-session
In-session subagents. Conflicts with executing-plans (which wants a separate session).
SDSystematic DebuggingRoot-cause the bug before proposing a fix
Evidence lives outside the agent. Reproduce the failure, read the log, then patch. Do not skip verification because the stack trace looked obvious.
TDTest-Driven DevelopmentWrite the failing test before implementation
Red, then green, then code. Agents skip the red step constantly.
UGUsing Git WorktreesIsolate feature work in a git worktree
Isolate via worktree. No-op if you ignore it and stay on the dirty branch.
VBVerification Before CompletionRun the proof before claiming done
Run the proof before claiming done. Agents say “done” without running the command.
WPWriting PlansBite-sized implementation plan after a spec exists
Bite-sized steps after a spec exists. Not for writing the spec (that’s spec-driven-development).
AAAPI and Interface DesignStable APIs, module boundaries, and public contracts
Encyclopedia When from addyosmani/agent-skills. Never-fire if the agent does not load it.
BTBrowser Testing with DevToolsChrome DevTools MCP for real-browser evidence
Requires the chrome-devtools MCP server. Without it, this is a prompt, not a browser.
CCCI/CD and AutomationBuild, test, and deploy pipelines as quality gates
Encyclopedia When from addyosmani/agent-skills. Not a CI vendor. Never-fire if the agent does not load it.
CRCode Review and QualityMulti-axis review before a change lands
This is a review workflow, not AGENTS.md. Do not treat it as project agent instructions.
CSCode SimplificationClarify working code without changing behavior
Clarify without changing behavior. Easy to “simplify” into a rewrite.
CDConstraint-Driven DevelopmentWrite the quality bar so agents cannot quietly lower it
Writes CONSTRAINTS.md. Useless if nobody reads it, or if the agent quietly lowers the bar anyway.
DADeprecation and MigrationSunset, migrate, and expand/contract without downtime
Expand/contract, then delete. Not a license to drop a column on Friday.
DADocumentation and ADRsRecord decisions so the next engineer and agent can follow
Record the decision. Agents write ADRs nobody asked for.
DDDoubt-Driven DevelopmentAdversarial review of high-stakes decisions before they stand
Adversarial review before the decision stands. Slow by design; skip it and you get confident wrongness.
FUFrontend UI EngineeringProduction-quality accessible, responsive UI
Production a11y/responsive UI. Overlaps frontend-design; this one is engineering, not vibe.
GWGit Workflow and VersioningCommits, branches, PRs, tags, and version bumps
Commits, PRs, tags. Not using-git-worktrees. Never-fire if the agent does not load it.
IRIdea RefineDiverge, then converge a vague idea into a sharp concept
Diverge, then converge. Idle unless the idea is still vague.
IMInterview MeOne-question interviews until the real intent is clear
One question at a time until intent is clear. Annoying if you already know what you want.
OAObservability and InstrumentationLogs, metrics, traces so production is diagnosable
Logs, metrics, traces. Not Sentry-the-product. Never-fire if the agent does not load it.
POPerformance OptimizationFrontend, backend, and query performance with evidence
Needs a metric. Profiling theater without a number is not this skill.
PAPlanning and Task BreakdownTurn a spec into ordered, estimable tasks
After a spec. Overlaps writing-plans. Never-fire if the agent does not load it.
SASecurity and HardeningInput, auth, data, and supply-chain hardening
Input, auth, data, supply-chain. Not a pentest and not Sentry security-review.
SAShipping and LaunchPre-launch checklist, rollout, and rollback
Checklist, rollout, rollback. Not a deploy button.
SDSource-Driven DevelopmentCite official docs instead of remembered APIs
Cite official docs. Agents still answer from memory.
SDSpec-Driven DevelopmentWrite the spec first when none exists yet
Write the spec first when none exists. Distinct from writing-plans, which assumes a spec already exists.
VRVercel React Best PracticesVercel Engineering React and Next.js performance patterns
Vercel Engineering React/Next performance patterns. MIT in SKILL.md frontmatter; vercel-labs/agent-skills has no LICENSE file. Broad React triggers.
VCVercel Composition PatternsReact composition that scales past boolean props
Compound components and boolean-prop cleanup, including React 19. Same undeclared-repo LICENSE. Not a performance skill.
VRVercel React Native SkillsReact Native and Expo performance and native-module patterns
React Native/Expo lists, animations, native modules. Same undeclared-repo LICENSE. Idle on web React.
URUse RailwayRailway signup, deploy, services, and infrastructure ops
False-fires on feature flags, MCP, and signup. Drives `railway up` for signup. A free tier exists.

Workers CLI for KV/R2/D1/Queues before you type it. Pulls a non-Cloudflare deploy toward wrangler.
WBWorkers Best PracticesProduction Workers anti-patterns
Production Workers anti-patterns (streaming, globals, bindings). Not a generic JavaScript review.
DODurable ObjectsStateful coordination on Workers
Stateful Durable Objects (SQLite, alarms, WebSockets). False-fires on any “stateful agent” that isn’t a DO.
TSTurnstile SpinBot check via Cloudflare Turnstile
End-to-end Turnstile widget plus siteverify. A generic captcha/bot-check still gets Turnstile.
SSSandbox Stable@cloudflare/sandbox on the default tag
@cloudflare/sandbox on the default tag. Wrong sibling if the app is on @next.
SNSandbox NextSandbox SDK 1.0 preview tag
Preview Catch: this is @cloudflare/sandbox@next, not the stable default. Vendor skill for Cloudflare.
CECloudflare Email ServiceSend and route mail from Workers
Workers email send/route and SPF/DKIM. “Add email” on a non-Workers app still steers here.
ASAgents SDKStateful agents on Cloudflare Workers
Cloudflare Agents SDK on Workers (state, RPC, Workflows). “MCP/chat agent” triggers steal from the MCP cluster.
AMAgents.mdThis writes AGENTS.md, not a skill
Loud Catch: this IS AGENTS.md / CLAUDE.md, not an agent skill. Do not confuse it with SKILL.md. Vendor skill from Sentry.
CSClaude Settings Auditpermissions.json from the repo shape
Writes Claude Code settings.json allowlists from repo shape. Sentry conventions leak; a generic repo still gets Sentry-shaped permissions.
DADjango Access ReviewIDOR and tenant isolation in Django
IDOR and tenant isolation in Django views/ORM. Idle off Django; not a generic auth review.
DPDjango Perf ReviewN+1 and queryset audits
N+1 and queryset audit, not a general perf skill. “Optimize Django” false-fires when the bottleneck isn’t the ORM.
SDSentry Doc CoauthoringStructured pass with the human still in it
Human-in-the-loop doc loop from getsentry/skills. Twin of Anthropic doc-coauthoring; never-fires if the agent just writes the doc.
GRGH Review RequestsUnread review-request notifications
Fetches unread GitHub review-request notifications. Needs gh + a team; an empty inbox looks like “no reviews.”
GSGHA Security ReviewPwn-request and workflow injection
Pwn-request and expression-injection in .github/workflows. Exploitation-shaped; not a green-CI checklist.
IPIterate PRCI + review loop until the PR is green
Loops CI and review until green, and will not wait for human approval or merge gates. Keeps pushing a draft you wanted parked.
PWPR WriterReviewer-facing title and body
Reviewer-facing title and body only. Will rewrite a PR description you already wrote.
POPrompt OptimizerEvals and model-family adapters
Prompt evals and OpenAI/Claude/Gemini adapters. Not product copy; will “optimize” a prompt that wasn’t the job.
SSSkill ScannerAudit a SKILL.md before you install it
Audits a SKILL.md for injection and secrets before install. Scanning is not the same as running the skill.
FBFind BugsBugs on this branch, not the whole repo
Bugs on this branch, not the whole repo. A repo-wide “find bugs” is a false fire.
SRSecurity ReviewOWASP-style pass with confidence scores
OWASP-style pass with confidence scores. Overlaps find-bugs and gha-security-review; not Sentry-product config.
DADocument API EndpointSentry @extend_schema and TypedDicts
Sentry @extend_schema and response TypedDicts. Dead outside getsentry API views.
CSClaude SecurityIn-session scan, then patches you apply
In-session scan, then patch files you apply. Claude Code plugin layout; not Sentry security-review.

Recommends hooks, skills, and MCP for Claude Code — it does not install them. Vendor lock.
ADAgent DevelopmentClaude Code subagent frontmatter
Claude Code subagent frontmatter (when-to-use, tools, colors). “Create an agent” outside plugins is a false fire.
CDCommand DevelopmentSlash commands for Claude Code plugins
Slash commands and AskUserQuestion inside Claude Code plugins. Not a Unix CLI skill.
HDHook DevelopmentPreToolUse and friends, in plugins
PreToolUse/PostToolUse/Stop hooks with ${CLAUDE_PLUGIN_ROOT}. Never-fires without that plugin layout.

plugin.json scaffold and auto-discovery. First-step only; overlaps the other plugin-dev siblings.
PSPlugin Settings.local.md config for a plugin
Per-project .claude/<plugin>.local.md YAML. “Plugin settings” in an editor is a false fire.
BMBuild MCP AppIn-chat widgets on an MCP server
In-chat MCP App widgets after the server exists. Not how to build the server (that’s HOLD build-mcp-server).
BMBuild MCPBBundle a local MCP with its runtime
Bundles a local MCP plus runtime as .mcpb. Desktop/filesystem MCP; not a hosted-server tutorial.
EAExpo AnimationReanimated, Gesture Handler, and haptics on device

ENExpo Native UIHIG, semantic color, and SF Symbols on Expo screens
HIG/SF Symbols screens; look vs @expo/ui primitives (expo-ui).
EPExpo Project StructureFolder layout for a new Expo Router app
new-app folders only; forbids restructuring existing apps.

Health of published EAS Update rollouts. Idle if you don’t OTA.
EWEAS Workflows.eas/workflows YAML that burns compute minutes

Vendor lock: Neon/Lakebase setup, pooled vs direct, DATABASE_URL. Trigger steals Prisma/Supabase Postgres work. Free $0 at neon.tech/pricing (100 projects, 0.5 GB, 100 CU-hours; compute suspends at cap). Parent neon stays OUT (HOLD — always-on overview).
NPNeon Postgres BranchesPick/create Neon branch type; schema-only is Beta

NFNeon FunctionsLong-running Node HTTP on a Neon branch. Public beta
Public beta. Vendor lock. False-fires on generic serverless — this is Neon Functions, not Vercel/AWS. NAME-COLLIDES with published Browserbase functions; slug is neon-functions, never functions. Free includes Functions capacity; costs past limits.
NONeon Object StorageS3-compatible storage that branches with Neon. Public beta
Public beta. Not AWS S3 and not R2 — Neon-only buckets that branch with Postgres. Vendor lock. Costs past the free Object Storage allowance.
LALiveKit AgentsVoice AI agent via LiveKit Cloud + Agents SDK
Cloud-only skill: skips self-host OSS. LiveKit Cloud + Inference is the path. Free Build $0, no CC, at livekit.com/pricing; Inference credits then paid. livekit-simulations stays DEFER.

False-fires on BullMQ (and generic queues). This is Inngest durable functions — Cloud + TypeScript. Hobby pauses at quota.
IEInngest EventsInngest event schema; 24h dedupe is vendor-specific
24-hour event-ID dedupe is Inngest-specific — not Kafka, not SQS, not a generic idempotency key. Cloud + TypeScript.
IFInngest Flow ControlConcurrency/throttle/batch. Hobby is 5 concurrent steps
Loud: Hobby is 5 concurrent steps. This skill will prescribe concurrency, throttle, and batching the free plan cannot run. Upgrade or the controls lie.
