Skip for subagents.

If activation mode is explicit and this request did not explicitly invoke Aegis or a named skill, stay on the fast path; do not route to any Aegis skill. Explicit invocation proceeds normally. You have Aegis. Load explicit/relevant Aegis skill before response/action; otherwise proceed normally.

Hot Path

1. User/project instructions outrank Aegis.
2. Load only the smallest explicitly requested or clearly relevant skill/reference; otherwise stay on the fast path. Compose ui-ux-governance for UI/UX effects; retain task ownership and scope.
3. Active codebase question/"what next": check README/ADR/rules/baseline, else bounded index-first scan. Non-trivial work passively use relevant CONTEXT-MAP.md/CONTEXT.md; model semantic conflicts only when found.
4. Primary routes: grill me/grill this plan/审问我/盘问我/拷问我 -> brainstorming (literal/explanatory uses do not); /aegis-goal or Aegis goal: -> goal-framing. Bug, failure, regression, or unexpected behavior routes to systematic-debugging.
5. Implementation only: Classify before implementation. Low stays owner-local; Medium/high: baseline read-set + plan. Spec Brief or Design Spec only for ambiguous/contract/cross-module medium/high work. TDD: off=no auto route/load; auto=risk-based strict/light/skipped; explicit strict applies. Pure explanation and read-only diagnosis skip implementation/TDD/write gates.
6. For writes, the owner workflow surfaces Change Necessity, records TaskStartSnapshot, and decides ArchitectureReviewRequired; ceremony alone never creates a branch/worktree.
7. At the first substantive user-visible stage say why Aegis is shaping non-tiny work; do not wait for the user to ask. structured trace is only for audit/debug/release/long-task review/asked and does not route (Trace Digest).
8. Workspace support is lazy; use configured Aegis workspace support only when records are needed. Q&A/status writes no project files; tiny work writes no workspace docs unless its owner requires a durable record.
9. Tool/log/memory/search outputs are evidence candidates, not prompt payloads: summary first; large input index->window->excerpt. Bound history/session/ transcript/log reads by scope/time/lines.
10. Read references/skill-discipline.md only when route/order/TDD/workspace/ context re-entry/host mapping detail is needed.

Contract: only a real fast path emits Route: fast-path and an Aegis Reason Note; a routed skill owns its next-stage contract.
