-
slowmist Bundle Badwhale API SkillRun authorized fake-deposit (false-recharge) security tests against a target address via the BadWhale API, and query which chains / networks / tokens are supported. Use when the user wants to test whether an exchange, wallet, or custody system correctly detects forged deposits, or asks what BadWhale supports. Triggers on: "fake deposit", "false recharge", "假充值", "充值检测测试", "deposit detection test", "BadWhale", "which chains/tokens are supported".

-
sebamar88 Bundle AI Debt ScannerAudit repositories for AI-generated technical debt and add lightweight guardrails during high-risk refactors or architecture-sensitive changes. Use when the user asks to scan, audit, review debt, or explicitly wants a guardrail before broad code changes.
-
serenakeyitan Bundle Citation Check SkillVision-enabled verification gate with web search. Use when users want to (1) verify slides/reports/PDFs/images against authoritative online sources, (2) validate that citations actually exist and say what's claimed, (3) check charts/graphs/tables for accuracy, (4) audit AI-generated content in doc-only mode (no external knowledge). Two modes - search mode validates against web, doc-only mode ensures everything traces to provided documents. Supports content in any language.
-
sergeykrin9 Bundle Verify By FailureAn eight-step working loop for coding agents on production systems: measure → plan with visible progress → build → verify by BREAKING it → look through the end user's eyes → stress-test the batch → take a meta position → log it → report. Use for any task of three or more steps: fixing a live service, a data migration, an audit, a batch of research, a new feature. Triggers: 'go ahead', 'fix it', 'figure it out', 'audit', 'stress test', 'check it with your own eyes', 'take it in any order'.
-
sergiobuilds Bundle UX Workflow CheckUse when you need to find what a real user would need but nobody wrote down — surfacing tacit assumptions, missing screens/features, and broken workflow links grounded in the user's actual intent, not imagined "best practices." Triggers: "UX check", "find what's missing", "workflow gaps", "is this annoying to use", "review this product for users", or when you're about to declare a one-pass review done. Works for UI, CLIs, reports, and docs — anything a user consumes, at plan stage (a spec) or audit stage (a built product). Not for visual polish (use a design-review tool) or idea/demand validation (use an idea-validation tool).
-
shaolongfei Bundle Android Reverse SkillExtract network APIs from Android APK, XAPK, JAR, and AAR files by decompiling with jadx and searching Retrofit, OkHttp, Volley, WebView, HttpURLConnection, GraphQL/Apollo, WebSocket, gRPC, auth headers, base URLs, resource URLs, certificate pinning, and network security config.

-
sharmasundip Bundle API Design ReviewerComprehensive API design reviewer that analyzes any API — OpenAPI/Swagger specs, GraphQL schemas, gRPC proto files, plain-English descriptions, or raw code snippets — and produces a scored audit report with actionable fix suggestions. Use this skill whenever the user mentions reviewing, auditing, critiquing, or improving an API design. Also triggers on: "check my API", "is this a good API?", "API best practices", "review this endpoint", "API anti-patterns", "REST maturity", "API naming conventions", "review my OpenAPI spec", "review my Swagger file", "GraphQL schema review", "gRPC service review", "rate my API", "API design feedback", "endpoint review", "API health check", or any request where a user shares API-related code, specs, or descriptions and wants quality feedback. Even if the user just pastes some endpoint definitions and says "what do you think?" — this skill should trigger.
-
shawnpana Skill Game TestingComprehensive human-style playtesting of a browser game. Use when asked to test, playtest, or verify a browser game build. You play like an experienced human game tester — you read the manual and play the intended loop, AND you bring genre instinct, probing every mechanic a gamer would expect from the game type and environment (movement, sprint, jump, crouch, reload, aim/ADS, melee, weapon handling, pickups, etc.). You judge whether the game is complete and feels right, and report what's broken, janky, or missing. This is thorough playtesting — NOT adversarial QA (no exploit/soft-lock/edge-case hunting) and NOT automation-driven (real human input only). Treats the game as a true black box — only the rendered screen + real input, never internal state or test hooks — and discovers mechanics (including how to aim and track targets) for itself by observation, so it generalizes to any game without per-game backdoors. Starts cold with no prior knowledge of the controls or rules — learns them by experimenting (tryin
-
shimellism-eng Bundle Essay WriterPlan, write, research, edit, review, and analyse essays while protecting the writer's voice and factual integrity. Use when asked for an essay writer, AI essay writer, essay writing assistant, essay helper, thesis, outline, argument, complete draft from scratch, essay editor, essay rewriter, essay improver, natural or human-sounding essay, evidence ledger, citation audit, rubric review, revision history, pattern audit, mechanical-pattern repair, personal statement, scholarship essay, lab report, literature review, source-based research, or an assessment of whether text shows probable AI-generated writing signals.

-
stevederico Bundle Hon MaguroEvaluate any project against fixed "Hon Maguro" quality bars via bin/maguro (init/links/eval), optional Lighthouse median for SCORE1, and a capped fix loop (max 2 rounds). Binary pass/fail — no partial credit. Use when the user says "hon maguro", "eval this project", "quality bar check", "is this project ready", "audit code quality", or wants a pass/fail verdict against Hon Maguro standards. Do not use for generic Lighthouse/PageSpeed-only or open-ended "inspect and fix" requests unless they ask for Hon Maguro / these bars.

-
sunfmin Bundle Skill DoctorDiagnose and fix skills by analyzing session logs for friction events — user interruptions, rejected actions, wrong approaches, test failures, and manual corrections. Cross-references friction against the patient skill's SKILL.md to find missing rules or enforcement gaps, generates patches with regression tests, and submits a PR. Use this skill after any development session where a skill underperformed, when you want to audit a skill's effectiveness, when debugging why a skill keeps making the same mistakes, or when the user says things like "fix this skill", "why does it keep doing X", "audit the skill", "doctor", or "skill-doctor".
-
supabase Skill Pg Security Release AnalysisGenerate a CVE catalog + Supabase impact analysis for a PostgreSQL security release.

-
suriyalk Bundle Verified Academic SourcingUse any time a student asks Claude to find sources, suggest citations, build/expand a reference list or bibliography, write a literature review, add citations to a paper, or check/audit citations already in a document. Also trigger whenever Claude is about to write a DOI, an author/year citation, a reference entry, OR a specific factual claim (a statistic, date, named study's finding, percentage) inside academic work — even inside a larger task like a proposal, thesis chapter, essay, or report. Stops hallucinated citations and hallucinated facts (fake DOIs, invented papers, wrong authors, made-up statistics) — a real academic integrity risk for NZ undergrad/postgrad students — and formats references in APA 7 including NZ/Māori conventions (macrons, iwi/hapū as corporate author, Waitangi Tribunal reports, NZ legislation, Stats NZ/govt reports). Don't skip this just because a citation or fact "seems obviously real" — that confidence is how fabrications end up in student work.

-
soheilmomeniii Bundle No SlopWrite prose clean of AI texture, or audit a draft through two gates: source fidelity (every quoted or attributed line verified against primary sources, four verdicts, correction log) and taste (mechanical tell scan plus a nine-dimension scorecard). Use when the user says "de-slop this", "slop check", "AI smell", "sounds like ChatGPT", "make it human", "humanize this", "sounds robotic", "reads like AI", "kill the em dashes", "verify the quotes", "fidelity check", "run the audit", or "taste pass", and when writing or rewriting X posts, threads, articles, essays, fiction scenes, book chapters, or landing copy that must not read AI-generated. Works at any length; the fidelity gate activates whenever quotes or attributions are present. Do not use for voice imitation (use a style-converter skill), UI design, or proving a text was AI-written: the banned list is house style, not a detector.
