v0.30.0 — agent-stack

• Every skill description is a router of 368 to 458 characters (was 929 to
  939; total 3,742 to 1,693). The operator's Claude Code skill listing measured
  29,995 of about 30,000 characters for 134 skills, and 81 skills showed no
  description; a plugin skill cannot be hidden, so length is the only lever. Each
  description is one "Use when" sentence, four or five English and Russian
  triggers, and a "Not for" boundary naming the sibling; agent-orchestrator
  carries the refusal phrase. Triggers: takes a colon inside the folded scalar.
• Every removed trigger phrase moved verbatim into a ## Triggers section of
  its SKILL.md body (8, 5, 11 and 9 phrases).
• agent-orchestrator keeps its scope list in the body. The description's
  "Covers" list (the saga across database and provider API among it) was the only
  place the body named that scope, and fix-as-01.01 reads it; it now sits under
  ## Triggers.
• test/validate.py: the member ratchet moves from 940 to the family soft cap
  of 500, and a description without a "Not for" boundary fails.
  The CI ratchet plant moves with it (500 passes, 501 fails on the ratchet), and
  the over-long plant pads past 1024 again.
