- api-and-interface-designaddyosmani/agent-skillsGuides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.DesignNo warnings★ 109.1K↓ —
- performance-optimizationaddyosmani/agent-skillsOptimizes application performance across frontend, backend, queries, and databases. Use when performance requirements exist, when you suspect performance regressions, when Core Web Vitals or load times need improvement, when N+1 query patterns need fixing, or when profiling reveals bottlenecks.DesignNo warnings★ 109.1K↓ —
- shipping-and-launchaddyosmani/agent-skillsPrepares production launches. Use when preparing to deploy to production, or when asking what needs to be in place before shipping. Use when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy.DevOpsNo warnings★ 109.1K↓ —
- ponytail-gainDietrichGebert/ponytailShow ponytail measured impact as a scoreboard: less code, less cost, more speed, from the agentic benchmark averages. One-shot display.EngineeringNo warnings★ 170.7K↓ —
- documentation-and-adrsaddyosmani/agent-skillsRecords decisions and documentation. Use when you need to document an architecture decision (ADR) or the reasoning behind a design choice, when changing public APIs, shipping features, or when you need to record context that future engineers and agents will need to understand the codebase.DesignNo warnings★ 109.1K↓ —
- ponytailDietrichGebert/ponytailLazy senior dev mode: the smallest change that fully solves the task, and a reply a busy human understands in one read. Use on any coding task (writing, fixing, refactoring, reviewing, choosing dependencies) and when the user says "ponytail", "be lazy", "simplest solution", "yagni", or complains about over-engineering or bloat. Levels: lite, full (default), ultra.WritingNo warnings★ 170.7K↓ —
- doubt-driven-developmentaddyosmani/agent-skillsSubjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when you want every assumption cross-examined before proceeding, when stress-testing a plan for hidden failure modes, when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production auth, security-sensitive logic, a high-stakes migration, irreversible operations), or any time a confident output would be cheaper to verify now than to debug later.SecurityNo warnings★ 109.1K↓ —
- browser-testing-with-devtoolsaddyosmani/agent-skillsTests in real browsers via Chrome DevTools MCP. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data. Requires the chrome-devtools MCP server to be configured.TestingNo warnings★ 109.1K↓ —
- git-workflow-and-versioningaddyosmani/agent-skillsStructures git workflow practices. Use when making any code change. Use when committing, branching, resolving conflicts, splitting uncommitted work in a messy working tree into clean atomic commits, opening or reviewing a pull request (PR), pushing to a remote, or when you need to organize work across multiple parallel streams. Use when cutting a release, choosing a semantic version bump, tagging, or writing a changelog.EngineeringNo warnings★ 109.1K↓ —
- ponytail-reviewDietrichGebert/ponytailQuality review of a change: is the logic right, is it safe, does it hold under real load, is risky code tested, is it fast enough, and is every line needed. Reads the connected code, not only the diff. Each finding is explained in plain English. Use for "review this", "code review", "review the last commit", "review my PR", "is this over-engineered", /ponytail-review.EngineeringNo warnings★ 170.7K↓ —
- ponytail-auditDietrichGebert/ponytailQuality audit of a whole repo: bugs, security holes, what breaks under real load, risky code without tests, slow paths, and what to delete, merge or split. Ranked, each finding explained in plain English. One-shot report, changes nothing. Use for "audit this codebase", "review the whole repo", "find bloat", "what can I delete", /ponytail-audit.SecurityNo warnings★ 170.7K↓ —
- pdfnexu-io/open-designExtract text, create PDFs, and handle forms. Useful for press releases, branded one-pagers, and printable design deliverables.DocumentsNo warnings★ 102.9K↓ —
- ponytailDietrichGebert/ponytailLazy senior dev mode for any coding task: the smallest change that fully solves it, and a reply a busy human understands in one read.EngineeringNo warnings★ 170.7K↓ —
- ponytail-debtDietrichGebert/ponytailHarvest every shortcut: comment into one debt ledger, so deferrals get tracked instead of forgotten. One-shot report.OtherNo warnings★ 170.7K↓ —
- planning-and-task-breakdownaddyosmani/agent-skillsBreaks work into ordered tasks. Use when you have a spec or clear requirements and need to break work into implementable tasks. Use when a task feels too large to start, when you need to estimate scope, or when parallel work is possible.PlanningNo warnings★ 109.1K↓ —
- ponytail-helpDietrichGebert/ponytailQuick reference for ponytail's modes, skills, and commands. One-shot display.OtherNo warnings★ 170.7K↓ —
- ponytail-auditDietrichGebert/ponytailQuality audit of the whole repo: bugs, security, real load, missing tests, speed, and what to delete. Most important first.SecurityNo warnings★ 170.7K↓ —
- ponytail-reviewDietrichGebert/ponytailQuality review of a diff: bugs, security, real load, missing tests, speed, and what to delete. Each finding says what goes wrong and how to fix it.EngineeringNo warnings★ 170.7K↓ —
- ponytail-helpDietrichGebert/ponytailQuick reference for ponytail levels, skills and commands. One-shot display. Use for /ponytail-help, "ponytail help", "how do I use ponytail".OtherNo warnings★ 170.7K↓ —
- interview-meaddyosmani/agent-skillsExtracts what the user actually wants instead of what they think they should want. Achieves this through one-question-at-a-time interview until ~95% confidence about the underlying intent. Use when an ask is underspecified ("build me X" without "for whom" or "why now"), when the user explicitly invokes ("interview me", "grill me", "are we sure?", "stress-test my thinking"), or when you catch yourself silently filling in ambiguous requirements before any plan, spec, or code exists.PlanningNo warnings★ 109.1K↓ —
- ponytail-gainDietrichGebert/ponytailShow ponytail's measured savings (code, cost, speed) from the benchmark. One-shot display. Use for /ponytail-gain, "what does ponytail save", "ponytail impact".EngineeringNo warnings★ 170.7K↓ —
- code-simplificationaddyosmani/agent-skillsSimplifies code for clarity. Use when refactoring code for clarity without changing behavior. Use when code works but is harder to read, maintain, or extend than it should be. Use when reviewing code that has accumulated unnecessary complexity.EngineeringNo warnings★ 109.1K↓ —
- docnexu-io/open-designRead, create, and edit .docx documents with formatting and layout fidelity via OpenAI's document skill.DocumentsNo warnings★ 102.9K↓ —
- ponytail-debtDietrichGebert/ponytailList every `shortcut:` comment (and older `ponytail:` ones) as a debt ledger. One-shot report, changes nothing. Use for "ponytail debt", "what did ponytail defer", "list the shortcuts", /ponytail-debt.OtherNo warnings★ 170.7K↓ —
