v2.3.4 — argument-hint coverage + concision

[2.3.4] — 2026-06-01 · argument-hint coverage + concision

Fixed

• argument-hint coverage: added the field to the 7 arg-taking skills that lacked it (audit, research, compress, sprint-dev, sprint-plan, sprint-review, ui-build) — all 37 skills now show an autocomplete arg chip. Display-only field; no change to invocation or argument delivery.

Changed

• argument-hint concision: trimmed the -- <prose explanation> tails from 15 hints (review, browse, code-doctor, conform, dep-health, doc-gen, next, perf-profile, quality-metrics, roadmap, release, setup, ship, sprint, ui-audit) to short chips, keeping every flag spelling. Aligns with the field's short-chip intent. Background: docs/_research/2026-06-01_command-argument-hints.md.
