[AdeGneus]

What does this PR do?

Type of change

• feat — new feature
• fix — bug fix
• docs — documentation only
• test — tests only
• refactor — neither fixes a bug nor adds a feature
• skill — new or updated bundled skill
• security — touches a safety invariant (requires maintainer review even for skills)

Checklist

Required for all PRs

• pytest tests/ -v passes with 0 failures
• ruff check --fix ori/ tests/ skills/ is clean
• Every new .py file has the Apache-2.0 license header
• If capability behavior changed, docs/CAPABILITY_MATRIX.md is updated in this PR
• If capability-impacting files changed but matrix update is intentionally not needed, add [skip-cap-matrix] in PR body with rationale
• PR description explains why, not just what

If you used AI assistance

• I can explain every line of AI-generated code in this PR
• I have read and understood all files I am modifying
• I am not submitting code I cannot defend in a review conversation

If this touches /ori/ (core runtime)

• I opened an issue and discussed this change before writing code
• Every new Tier D code path has test coverage
• No new dependencies added without prior issue discussion

If this adds or modifies a bundled skill (/skills/)

Community skills go to ori-platform/ori-skills — not here.
PRs to /skills/ in this repo are for first-party bundled skills only.

• I opened an issue and got maintainer approval before writing this skill
• action_tier is declared on every trigger
• bypass_llm: true is only paired with action_tier: D
• Tier C triggers declare safe_default_action
• hooks.py is clean and minimal (bundled skills bypass the sandbox — they are implicitly trusted)
• No subprocess calls in hooks
