Adds the profile recommendation step to /ultrabrief-local Phase 4. The
brief stays universal (same questions, same template); the new step is
purely a processing-decision layer that records which profile downstream
commands should apply.
What lands:
- agents/profile-recommender.md — new sonnet agent that scores available
profiles against the finalized brief (keyword + NFR-signal matching,
axis bumps, hallucination gate that forbids inventing profile names).
Emits a fenced JSON block with ranked entries.
- templates/ultrabrief-template.md — frontmatter gains
recommended_profile, profile_match, profile_rationale (default values
applied when only `default` is available — true at M1).
- commands/ultrabrief-local.md — Phase 4 gains Step 4h with explicit
branches: short-circuit when only `default` exists; AskUserQuestion
confirmation when top score ≥ 0.7; explicit fallback message when below
threshold; manual selection sub-question on user override. Persists the
three frontmatter fields to brief.md after user confirmation. JSON
parser failure falls back to `default` with `profile_match: fallback`
rather than blocking — silent fallback is the worst outcome, but a
*visible* fallback is acceptable.
- scripts/profile-loader.mjs — adds selectRecommendation(ranked, opts) +
RECOMMENDATION_THRESHOLD=0.7 export. Single source of truth for the
threshold logic so the command spec and the helper agree.
- scripts/profile-loader.test.mjs — 10 new tests for selectRecommendation
(default-only, empty/malformed input, above/below threshold, custom
threshold, max-by-score, missing fields). Total now 36/36.
- README.md / CLAUDE.md / marketplace landing — docs reflect M0 + M1
shipped, M2 + M3 still pending.
In practice nothing changes for users at M1 because only `default` is
available — Step 4h takes the short-circuit path and writes
`profile_match: default-only`. M2 ships the additional profiles that
make the recommender meaningful.
