- 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↓ —
- test-driven-developmentaddyosmani/agent-skillsDrives development with tests using the red-green-refactor loop. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality. Use when asked to add tests to a function, fix a bug in it or change its behavior, even when the code is pasted inline and the request does not mention tests.TestingNo warnings★ 109.1K↓ —
- ponytail-helpDietrichGebert/ponytailQuick reference for ponytail's modes, skills, and commands. One-shot display.OtherNo warnings★ 170.7K↓ —
- code-review-and-qualityaddyosmani/agent-skillsConducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch. Use when asked to review a diff or a pull request, even when the diff is pasted inline.EngineeringNo 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↓ —
- 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↓ —
- debugging-and-error-recoveryaddyosmani/agent-skillsGuides systematic root-cause debugging. Use when tests fail, builds break, something that worked yesterday broke, behavior doesn't match expectations, or you encounter any unexpected error. Use when you need to figure out what broke and why — a systematic approach to finding and fixing the root cause rather than guessing.EngineeringNo 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↓ —
- 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-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↓ —
- 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-debtDietrichGebert/ponytailHarvest every shortcut: comment into one debt ledger, so deferrals get tracked instead of forgotten. One-shot report.OtherNo warnings★ 170.7K↓ —
- 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↓ —
- 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↓ —
- 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↓ —
- spec-driven-developmentaddyosmani/agent-skillsCreates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when drafting a PRD or requirements document with objectives and scope, or when requirements are unclear, ambiguous, or only exist as a vague idea. Use when a single requirement spans several independently testable capabilities and needs decomposing into a capability map of modules before specifying.PlanningNo warnings★ 109.1K↓ —
- 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↓ —
- using-agent-skillsaddyosmani/agent-skillsDiscovers and invokes agent skills. Use when starting a session, or when you need to decide which skill or workflow applies to the piece of work at hand. This is the meta-skill that governs how all other skills are discovered and invoked.ProductivityNo warnings★ 109.1K↓ —
- 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↓ —
- context-engineeringaddyosmani/agent-skillsOptimizes agent context setup. Use when starting a new session, when agent output quality degrades, when switching between tasks, or when you need to configure rules files and context for a project.ProductivityNo 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↓ —
- docnexu-io/open-designRead, create, and edit .docx documents with formatting and layout fidelity via OpenAI's document skill.DocumentsNo warnings★ 102.9K↓ —
interview-me
addyosmani/agent-skills
From the author
Extracts 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.
