- wioworkersio/skillsTesting workflow skill for finding high-value test candidates, writing focused tests, generating realistic workloads, reviewing test value, and diagnosing test-suite health. Use for prompts about what to test next, adding or improving tests, reviewing whether a test is worth keeping, low-signal or flaky tests, workload scenarios, or test-suite trust. Do not use for general QA discussion unless the user wants a concrete testing workflow or artifact.TestingNo warnings★ 209↓ —

- performance-memocognyai/claude-code-marketing-skillsThe Monday memo a sharp analyst would write — joins spend on every ad platform to qualified calls, deals, revenue, refunds and churn per campaign ID, catches cheap customers who churn, and ends every line in a decision — keep, kill, change or testTestingNo warnings★ 111↓ —

- social-enginecognyai/claude-code-marketing-skillsUse organic LinkedIn and X as a free creative test kitchen — listen to what people complain about and ask for, draft a week of hooks from customer language and founder opinions, schedule only what you approve, then promote the posts the algorithm picked up into paid testsTestingNo warnings★ 111↓ —
- recurring-character-diary-comicZSeven-W/craft-skillsCreate, audit, and repair short page-native diary comics around an existing authorized recurring character, with story-directed page rhythm, exact dialogue, directional-surface proof, and original-resolution visual QA. Use when extending an established recurring-character series from an anecdote, conversation, dream, or viewpoint, or when checking or repairing identity, anatomy, text, prop, relation, continuity, or layout defects. Do not use for standalone character design, educational explainers, infographics, one-off illustrations, generic memes, unauthorized characters or marks, imitation of a named living artist, watermarking, or social-platform publishing.TestingNo warnings★ 233↓ —
- pricing-strategyLeadMagic/gtm-skillsDesign SaaS pricing strategy using willingness-to-pay research, packaging, value metrics, competitive anchors, and expansion paths.

- skill-designerBaggaT236/AI-Trading-SkillsDesign new Claude skills from structured idea specifications. Use when the skill auto-generation pipeline needs to produce a Claude CLI prompt that creates a complete skill directory (SKILL.md, references, scripts, tests) following repository conventions.TestingNo warnings★ 137↓ —
- hello-worlddcc-mcp/dcc-mcp-coreExample skill — minimal greeting tool demonstrating the dcc-mcp-core skill system. Use only when testing a new skill installation or onboarding to the skill authoring workflow. Not intended for production use.TestingNo warnings★ 70↓ —

- build-scenario-teststamdogood/builder-essential-skillsInspect an unfamiliar repository, turn a focused Markdown behavior scenario into a deterministic test in the repository's native test stack, run it, and preserve traceability between intent and code. Use when asked to add scenario tests, compile acceptance criteria or Given/When/Then Markdown into executable tests, reproduce a user-visible regression, or convert a narrow workflow specification into stable web, API, CLI, desktop, or mobile interaction coverage. Do not use for broad exploratory journeys or agent-judged smoke tests.TestingNo warnings★ 225↓ —

- feature-verifyarcasilesgroup/ai-engineeringCross-verify a just-finished feature with throwaway browser tests driven by chrome-headless-shell — proves the feature actually does what it was supposed to do, and proves the change didn't break the routes and components that depend on it. Reports a verdict with evidence and never edits app code. Use this whenever a feature, fix, refactor, or UI change has just been completed — including when the user says "done", "that's implemented", "verify this", "does it work?", "make sure nothing broke", "check for regressions", or asks whether a change is safe to commit, merge, or ship. Applies to any web app with a dev server (Next.js, Vite, Remix, SvelteKit, CRA, static). Reach for it even when the user never says "e2e", "browser test", or "screenshot".TestingNo warnings★ 61↓ —
- arborKalarisLabs/research-agent-skillsAutonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g. "get my model's eval score up", "improve this agent/harness", "tune this pipeline", "beat the baseline on this benchmark", "run a search over approaches and keep the best", "do an MLE-bench / Kaggle-style optimization", or any long-horizon "make this artifact better and don't just memorize the dev set" task. Trigger it even when the user doesn't say "Arbor" or "hypothesis tree" but describes repeated experiment-and-evaluate loops, branching exploration of competing ideas, or worries about a dev/test gap. Runs Claude itself as the coordinator with subagent executors in isolated git worktrees; for the standalone `arbor` CLI tool see references/arbor-upstream.md.TestingNo warnings★ 65↓ —
- qa-memoryfishzjp/qa-skillsMaintain the .qa/ knowledge base of cross-session QA knowledge (quirks, flaky verdicts, defect patterns, contract changes); read before test tasks. Not for: pipeline state, case files (test-case-writing). 维护被测项目 .qa/ 跨会话知识库（环境怪癖、flaky、缺陷模式、契约变更）读写治理；任务前先读取。不用于：流水线状态、用例文件读写（test-case-writing）。TestingNo warnings★ 52↓ —
- dual-axis-skill-reviewerBaggaT236/AI-Trading-SkillsReview skills in any project using a dual-axis method: (1) deterministic code-based checks (structure, scripts, tests, execution safety) and (2) LLM deep review findings. Use when you need reproducible quality scoring for `skills/*/SKILL.md`, want to gate merges with a score threshold (for example 90+), or need concrete improvement items for low-scoring skills. Works across projects via --project-root.TestingNo warnings★ 137↓ —
- skillhone-auto-optimizationTencent/SkillHoneMandatory interception workflow for a reproducible defect encountered while any Agent is using a skill. Invoke this before editing implementation files or installing dependencies when a referenced script is missing, a documented command or repository test fails, or another target-skill defect is confirmed. First create or reuse a sanitized local Issue, then let SkillHone dispatch the repair into a tested Git-backed pull request. This applies regardless of the Agent, current working directory, or the user's original task. No eval repo or benchmark data is required.TestingNo warnings★ 170↓ —
- matlabKalarisLabs/research-agent-skillsDesigns, reviews, and migrates MATLAB R2026a and GNU Octave numerical code, covering functions with arguments blocks, arrays and indexing, tables and timetables, matlab.unittest tests, MATLAB Projects, exportgraphics figures, MAT file inventory, and MATLAB-Python interoperability. Includes static helper scripts that scan .m files, plan argv commands, and hash artifacts without executing anything. Use when writing or reviewing .m code, migrating code between MATLAB releases or to Octave, setting up reproducible tests and projects, inspecting an untrusted MAT or .mlx file safely, or checking Python Engine compatibility. Do not use for pure Python numerical work with NumPy or SciPy.TestingNo warnings★ 65↓ —
- orchestrateskillberry-ai/cap-evolveDrive the entire cap-evolve pipeline end to end, autonomously. Use when the user wants the whole optimization run with minimal hand-holding. Sequences intake → implement-and-check → baseline → the chosen algorithm loop → finalize → report, enforces the cap-evolve-check hard gate before spending budget, decides when to stop (budget/stall), and surfaces the honest test number at the end. Reads capevolve.yaml; respects the ask-user-if-missing rule for inputs.TestingNo warnings★ 66↓ —
