Introduces a profile-loader infrastructure for runtime-instantiable
ultraplan variants (depth × domain × goal axes). M0 ships only the
`default` profile, which mirrors the current hardcoded Phase 5/9 agent
set — so existing flows are unaffected.
What lands:
- profiles/default.yaml — schema v1, lists current 8 exploration agents
+ 2 review agents, captures today's adversarial regime
- scripts/profile-loader.mjs — null-deps Node loader with limited-subset
YAML parser, listProfiles(), loadProfile(), validateProfile() that
cross-checks every referenced agent exists in agents/
- scripts/profile-loader.test.mjs — 26 node:test cases (parser, validation,
loader, integration with built-in default.yaml)
- commands/ultraplan-local.md — Phase 1 gains a "Resolve the profile"
step (--profile flag → brief.recommended_profile → default fallback)
and prints profile + source in the mode report. Phase 5/9 unchanged.
- README.md, CLAUDE.md, marketplace README — documentation of the M0
foundation, the universal-brief design principle, and the M1/M2/M3
milestones to come.
M1 (next) wires profile recommendation into ultrabrief Phase 4. M2
ships the additional built-in profiles (quick, bugfix, feature, refactor,
security-deep, research-heavy) and replaces the hardcoded Phase 5 agent
table with profile-driven selection. M3 adds user-extensible profiles.
