Using Aegis

<SUBAGENT-STOP>Skip for subagents.</SUBAGENT-STOP>

<EXTREMELY-IMPORTANT>

You have Aegis. Load explicit/relevant Aegis skill before response/action;

otherwise proceed normally.

Hot Path

• User/project instructions outrank Aegis.
• 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.

• 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.
• /aegis-goal or Aegis goal: loads goal-framing before routing.
• Bug, failure, regression, or unexpected behavior routes to systematic-debugging; quick bug lane owns Change Necessity before source edits.
• 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-module medium/high work. Shared/core/contract/cross-module never low without evidence. Source edits/new paths: owner workflow surfaces Change Necessity.
• Before the first repo write, the coordinator records TaskStartSnapshot.

Complexity, TDD, planning, or subagents alone do not

justify branch/worktree creation.

• Non-tiny loaded skill: at first substantive user-visible stage say why Aegis is shaping work/risk; do not wait for the user to ask. structured trace only for audit/debug/release/long-task review/asked; Trace Digest does not route. Tiny stays implicit.
• ArchitectureReviewRequired: yes for medium/high architecture/contract/

cross-module/owner/source-of-truth/fallback/adapter/baseline; carry to

verification.

10. Workspace support is lazy; use configured Aegis workspace support only when records needed. Fast Q&A/status/tiny edits write no files.

11. Load smallest needed skill/reference.

12. Tool/log/memory/search outputs are evidence candidates, not prompt payloads;

summary first, large input index->window->excerpt.

13. No history/sessions/transcripts/large logs by default; bound requested

evidence by scope/time/lines.

14. Unclear host tool-name mapping: read smallest relevant reference.
