| # | Skill | Repository | Stars | Used in | Tokens | Auto-check | Licence | Updated |
|---|---|---|---|---|---|---|---|---|
| 1 | Guides a conversation that takes a vague idea through divergent and convergent thinking and ends in a markdown one-pager covering scope and assumptions. | addyosmani/ | 104k | 6 repos | ~2k | Automated safety check: Pass | MIT | 6 days ago |
| 2 | Asks one question at a time, each with a best guess attached, until the agent is about 95 percent sure what you really want, before any plan, spec or code. | addyosmani/ | 104k | 6 repos | ~3.8k | Automated safety check: Pass | MIT | 6 days ago |
| 3 | Meta-skill for choosing which workflow skill fits the task at hand, plus always-on habits: surface assumptions, stop on confusion, push back, keep it simple and stay in scope. | addyosmani/ | 104k | 4 repos | ~2.4k | Automated safety check: Pass | MIT | 6 days ago |
| 4 | Connects an agent to a real Chrome instance through the Chrome DevTools MCP server, so it can inspect the DOM, read console errors and profile performance directly. | addyosmani/ | 104k | 4 repos | ~3.5k | Automated safety check: Warn | MIT | 6 days ago |
| 5 | Records a project's quality bar in CONSTRAINTS.md and watches diffs for signs an agent quietly weakened it, such as suppressions, skipped tests or lowered thresholds. | addyosmani/ | 104k | 2 repos | ~5.2k | Automated safety check: Pass | MIT | 6 days ago |
| 6 | Sets git habits for every change: short-lived branches, atomic commits with descriptive messages, clean pull requests, plus versioning, tagging and changelogs for releases. | addyosmani/ | 104k | 2 repos | ~3.5k | Automated safety check: Notes | MIT | 6 days ago |
| 7 | Applies a stop-the-line rule and a step-by-step triage when tests fail, builds break or something stops working, aiming at the root cause instead of guesses. | addyosmani/ | 104k | 1 repo | ~2.6k | Automated safety check: Pass | MIT | 6 days ago |
| 8 | Delivers a change in thin vertical slices, each implemented, tested, verified and committed before the next, using vertical, contract-first or risk-first slicing. | addyosmani/ | 104k | 1 repo | ~2.3k | Automated safety check: Pass | MIT | 6 days ago |
| 9 | Prepares a production launch with a pre-launch checklist, monitoring, a staged rollout and a rollback plan so every release is reversible and observable. | addyosmani/ | 104k | 1 repo | ~2.8k | Automated safety check: Pass | MIT | 6 days ago |
| 10 | Writes a structured specification before any code, moving through gated specify, plan, tasks and implement phases, with an optional capability map for multi-part requests. | addyosmani/ | 104k | 1 repo | ~3.2k | Automated safety check: Pass | MIT | 6 days ago |
| 11 | Applies a threat-model-first approach to web code that handles untrusted input, authentication, data storage, dependencies or personal data. | addyosmani/ | 104k | 1 repo | ~4.4k | Automated safety check: Notes | MIT | 6 days ago |
| 12 | Grounds every framework-specific code decision in official documentation instead of memory, fetching and citing the source first. | addyosmani/ | 104k | 1 repo | ~2.5k | Automated safety check: Warn | MIT | 6 days ago |
