<SUBAGENT-STOP>Skip for subagents.</SUBAGENT-STOP> <EXTREMELY-IMPORTANT> You have Aegis. Load explicit/relevant Aegis skill before response/action; otherwise proceed normally. </EXTREMELY-IMPORTANT> ## Hot Path 1. User/project instructions outrank Aegis. 2. Active codebase question/"what next": check README/ADR/rules/baseline, else bounded index-first scan. Non-trivial owners passively use relevant `CONTEXT-MAP.md`/`CONTEXT.md`; compose `establishing-project-context` only for semantic delta/conflict. Create baselines only with evidence. 3. Direct grilling or plan/design pressure-tests (`grill me`, `grill this plan`, `审问我`, `盘问我`, `拷问我`) route to `brainstorming`; literal/explanatory uses do not. 4. `/aegis-goal` or `Aegis goal:` loads `goal-framing` before routing. 5. Bug, failure, regression, or unexpected behavior routes to `systematic-debugging`; quick bug lane owns Change Necessity before source edits. 6. Classify before implementation/start/resume/compaction. Low: intent, baseline, verification. Medium/high: baseline read-set + plan. TDD: off=no auto route/load; auto=strict/light/skipped; explicit request applies. Spec Brief or Design Spec only for ambiguous/contract/cross-modu

About this skill
What does the using-aegis skill do?

Use when starting a turn or checking Aegis skill routing.

How do I install it?

Run `npx skills add GanyuanRan/Aegis --skill using-aegis --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From GanyuanRan/Aegis, a repository with 902 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
