Coding & Development
mattpocock/diagnosing-bugs
Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.
$ npx skills add mattpocock/skillsJuliusBrussee/surgical-patch
Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.
$ npx skills add JuliusBrussee/cavemanJuliusBrussee/verify-and-stop
Prove existing work meets acceptance conditions without expanding scope. Use for validation-only tasks, completion checks, focused gate runs, and last-mile proof.
$ npx skills add JuliusBrussee/cavemanJuliusBrussee/safe-refactor
Restructure code while preserving behavior. Use for extraction, consolidation, ownership moves, or cleanup where verification must bracket structural edits.
$ npx skills add JuliusBrussee/cavemanmattpocock/to-spec
Turn the current conversation into a spec and publish it to the project issue tracker: no interview, just synthesis of what you've already discussed.
$ npx skills add mattpocock/skillsmattpocock/wizard
Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.
$ npx skills add mattpocock/skillsmattpocock/implement-spec
Implement a specification in code.
$ npx skills add mattpocock/skillsmattpocock/to-tickets
Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker (edges as text in one file per ticket locally, or native blocking links on a real tracker).
$ npx skills add mattpocock/skillsmattpocock/wayfinder
Plan a huge chunk of work (more than one agent session can hold) as a shared map of decision tickets on your issue tracker, and resolve them one at a time until the way to the destination is clear.
$ npx skills add mattpocock/skillstderoussel/codebase-audit
Runs a ranked, evidence-backed audit of a product, codebase, or subsystem, ending in a verify list that separates proven findings from inferred ones. Use when the user asks for an audit, a gap analysis, a deep read, a bug hunt, a readiness check, a re-audit, a state reconciliation, or asks what they are not seeing. Trigger phrases include "audit", "gap analysis", "what am I missing", "deep audit", "readiness", "bug hunt", "review the whole thing". Produces findings and a verify list; does not fix.
$ npx skills add tderoussel/agent-skillstderoussel/overnight-build
Composes an autonomous unattended Claude Code build prompt that survives usage-limit resets via BUILD_LOG.md checkpointing, plus the launcher that restarts it. Use when the user asks for an overnight build, an autonomous build, a build to run while they sleep, an unattended or unsupervised session, or any long build they will not be monitoring. Trigger phrases include "overnight build", "run overnight", "build while I sleep", "autonomous build", "let it run", "unattended". Produces a single copyable prompt; does not run the build.
$ npx skills add tderoussel/agent-skillsdtiger1889-ops/breakdown
Convergent, action-first problem decomposition (the terse twin of /fanout). Use ONLY when the user types /breakdown or says "break this down" / "break it down" / "decompose this". Takes ONE tangled or ambiguous problem and returns the single smallest next ACTION plus a collapsed full plan. Terse, no hand-holding, no capability narration. Do NOT use for open-ended ideation with many valid answers (that is /fanout), and do NOT use when the task is already one clear action.
$ npx skills add dtiger1889-ops/claude-harness-toolboxdtiger1889-ops/prove
The user suspects something in your last response was made up, or contradicts
$ npx skills add dtiger1889-ops/claude-harness-toolboxprisma/prisma-mongodb-upgrade
Decision and migration guide for Prisma ORM MongoDB projects on v6, which have no upgrade path to v7. Use when a MongoDB project asks about upgrading Prisma, when "upgrade to prisma 7" comes up in a project with provider = "mongodb", or when evaluating a move to Prisma Next. Triggers on "upgrade prisma mongodb", "prisma 7 mongodb", "mongodb prisma migration", "prisma next mongodb".
$ npx skills add prisma/skillstderoussel/ship-gate
Verification gate for a Next.js-on-Vercel + Supabase + GitHub Actions stack, to run before claiming anything is shipped, deployed, live, merged, passing, or done. Use before saying a change is in production, before merging a PR, before reporting CI green, and before writing any status into a document — even if the user does not ask for verification. Trigger phrases include "is it live", "did it deploy", "ship it", "merge it", "is CI green", "confirm prod", "did that work". Encodes traps where the obvious check returns a false pass.
$ npx skills add tderoussel/agent-skillsprisma/prisma-compute
Prisma Compute deployment and hosting guide. Use whenever the user mentions Prisma Compute, `prisma.compute.ts`, `defineComputeConfig`, deploying or hosting a Prisma app, `@prisma/cli app deploy`, `compute:deploy`, `create-prisma --deploy`, `PRISMA_SERVICE_TOKEN`, Compute auth/workspaces, apps/deployments/build logs/domains, localhost vs `0.0.0.0`, deploy port binding, or framework deploy readiness for Hono, Elysia, Next.js, TanStack Start, Astro, Nuxt, Svelte, Nest, Turborepo, or custom/prebuilt artifacts.
$ npx skills add prisma/skillsskills-directory/codex
Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing
$ npx skills add skills-directory/skill-codexemernuness/gauntlet-loop
Turns an ambitious request into a self-judging, self-improving agent run instead of a first draft. Sets a concrete external quality bar, splits the goal into judgeable pieces, gives each one a separate critic with clean context, forces blind A/B against the bar, and loops with no fixed round count. Routes every spawned agent to the cheapest model and effort that can do its job, so fan-out does not burn tokens. Use for ANY complex or open-ended build, not only games. Trigger when asked to build, create, design, refactor, redesign, optimize or "make excellent" any artifact (app, site, UI, game, API, service, pipeline, report, article, campaign, research), and on goal, loop, gauntlet, fan out, subagents, AAA, production quality, best in class, keep improving, compare against a reference, or any concern about token cost, budget, model choice or reasoning effort in a multi-agent run. Also when a broad goal arrives with no implementation detail, or when about to ship a first draft as final.
$ npx skills add emernuness/gauntlet-loop-skilladdyosmani/constraint-driven-development
Establishes a project's quality bar as a written contract and stops agents quietly lowering it. Interviews the user on which dimensions matter, supplies sane default thresholds when they have no number in mind, records everything in CONSTRAINTS.md, and watches the diff for a weakened bar — new @ts-ignore or eslint-disable suppressions, skipped or deleted tests, assertions stripped out, unimplemented stubs, thresholds edited down. Use when no quality bar is written down, when the user says "set up constraints" or "define our standards", when the user wants dimensions they care about — accessibility, web performance, coverage — set up as enforced constraints, when an agent keeps silencing checks or skipping tests to get to green, when you need a coverage or performance threshold and don't know what number to pick, or when an agent writes more code than anyone will read.
$ npx skills add addyosmani/agent-skillsagent-sh/agnix-skill
Use when user asks to 'lint agent configs', 'validate skills', 'check CLAUDE.md', 'validate hooks', 'lint MCP'. Validates agent configuration files against 456 rules.
$ npx skills add agent-sh/agnixaddyosmani/observability-and-instrumentation
Instruments code so production behavior is visible and diagnosable. Use when adding logging, metrics, tracing, or alerting. Use when shipping any feature that runs in production and you need evidence it works. Use when production issues are reported but you can't tell what happened from the available data.
$ npx skills add addyosmani/agent-skillsgetrdone/html-page-standard
Default contract for new static HTML pages from screenshots, bitmap mockups, or raster designs. Use for HTML projects, landing pages, clone a screenshot, tokenize CSS, TUNE blocks, theme tokens, studio-web repair after clone, layout packs. Do not use for Wix Velo-only edits or when the user names a different pipeline.
$ npx skills add getrdone/agent-skillschaseai-yt/claudex-loop
Harden a plan with independent Claude/Codex review, then optionally build and cross-inspect it. Start in either Claude Code or Codex: the host plans and the other provider reviews. Use for claudex this plan, claudex-loop, or the legacy crucible trigger; not for trivial edits.
$ npx skills add chaseai-yt/claudex-loopManueldav2/begin
Use at the START of work in an unfamiliar or half-remembered codebase, or when the user says "understand this codebase", "get up to speed", "where do I start", "what is this repo", "/begin", or asks what they were last working on. Derives the important and complex parts from the import graph, git churn and recent PRs, links every hot file to the user-facing surface it serves, and writes BEGIN.md — a living knowledge graph of the code that stays honest on every push.
