v0.15.0 — sheleg-dev

• Every skill's front-matter description is now a router, not a manual: one
  "Use when" sentence, a "Not for" boundary naming the sibling skill, the opt-out
  phrase (no wiring, без обвязки) and a short English and Russian trigger list.
  Lengths before and after: stripe-billing 965 to 459, error-tracking 962 to 395,
  frontend-performance 885 to 412, crypto-payments 884 to 398, ad-tracking 859 to 408,
  google-signin 821 to 386, google-auth 798 to 417 (6,174 to 2,875 chars in total).
• Why: Claude Code shares about 30,000 chars of skill listing across every installed
  skill. Measured on 2026-10-20, the operator's listing held 29,995 chars for 134 skills
  and 81 of them showed no description. Plugin skills cannot be hidden, so description
  length is the only lever.
• Every trigger phrase removed from a description moved verbatim into a new
  ## Triggers section at the end of that skill's body, so the family's routing hook
  still finds each of its words in the skill's text.
• test/validate.py refuses a description over 500 chars (the family cap; the
  standard's 1024 stays the hard limit). The CI plant that pads crypto-payments by
  320 chars now trips this cap.
• docs/evals/stripe-billing.md restates the recomputed body budget (4603 tokens,
  403 lines).
