Summary

• shorten both the bundled frontmatter and registered plugin metadata from 189 to 54 characters
• keep the trigger specific to failed or stuck Hookdeck event runs
• leave the full workflow and recovery guidance unchanged

Why

Long skill descriptions are truncated in agent catalogs and can create false-positive activation pressure. This keeps the activation rule visible and precise while preserving progressive disclosure in the skill body.

Risk

Low: packaged prose-only change; no runtime code or tool contract changes. Per repository policy, this is a PATCH-level shipped change.

Verification

• python -m ruff check . — pass
• python -m pytest tests/test_register.py -q — 4 passed after aligning registered metadata
• python -m pytest — 319 passed, 2 Windows-only baseline failures (test_a_tilde_in_cli_config_path_is_expanded, test_without_an_api_key_it_degrades_to_the_ambient_session)
• python -m build — pass
• inspected built wheel: both hookdeck/skills/triage-webhook-failures/SKILL.md and hookdeck/__init__.py contain the 54-character description
• git diff --check — pass

Remaining risk

Linux CI should provide the authoritative full-suite result; the two local failures are in platform-specific path/subprocess assumptions outside this markdown-only diff.
