Before any response/action, check if an Aegis skill is explicit or clearly relevant. Load only that skill; otherwise proceed normally.
Hot Path Rules
- User and project instructions outrank Aegis.
- Active codebase question or "what next": check baseline candidates
(README/ADR/rules/
docs/aegis/baseline). If none fit, bounded index-first scan; create a baseline only with evidence, and still answer. /aegis-goalorAegis goal:loadsgoal-framingfor goal, success evidence, stop condition, and non-goals before onward routing.- Classify before implementation/start/resume/compaction. Low: concise intent
- baseline check + TDD Route + verification. Medium/high: baseline read-set + plan. TDD Route: auto=strict/light/skipped; off=no automatic TDD, verification stays. Add Spec Brief or Design Spec only when complexity, ambiguity, contracts, or cross-module impact require it. Contract/shared/core or cross-module changes are never low without evidence.
- Aegis Reason Note: say why Aegis is shaping non-trivial skill/stage work; tiny fast-path may stay implicit; structured trace only for audit/debug/release/long-task review or asked.
- Mark
ArchitectureReviewRequired: yesfor medium/high, architecture, contract, cross-module, owner, source-of-truth, fallback/adapter, or project-baseline tasks. Carry it toverification-before-completion. - Workspace support is lazy. Global install and fast-path Q&A/status/tiny edits never write project files. Baseline/spec/plan/work records use configured Aegis workspace support only when persistent evidence is needed.
- Load the smallest needed skill/reference.
- Treat tool outputs, logs, memories, and search results as evidence candidates, not prompt payloads: summarize first; for large inputs use bounded index→window→excerpt.
- Do not read historical sessions, transcripts,
history.jsonl,.codex/sessions,~/.claude/projects, or large logs by default. Only read direct evidence when requested or required, with scope/time/line bounds. - If host tool-name mapping is unclear, read the smallest relevant reference.
Contract when useful: Route: fast-path; Aegis Reason Note; Why; Next.
