Add a new Board Support Package (BSP) crate to the Tyrne workspace — from crate skeleton through boot checklist to first QEMU or hardware boot.
Propose and draft a new Architecture Decision Record (ADR) in MADR format for Tyrne.
Run an independent verification pass over artefacts in `Proposed` / `In Review` waiting-for-promotion states. Distinct from code-review (style + correctness on a diff) and security-review (adversarial axis pass) — this skill verifies that the artefacts' claims about their own state match reality and produces a Done-promotion verdict.
Produce a review artifact in `docs/analysis/reviews/<type>-reviews/`, following that type's master plan. Works for business / code / security / performance-optimization reviews.
Change an existing Tyrne standard correctly — write or update the motivating ADR first, then update the standard file.
Add a new Rust crate to the Tyrne workspace following the dependency policy in `infrastructure.md`.
Introduce or audit an `unsafe` region in Tyrne — writing the `SAFETY:` comment, adding the audit-log entry, and queuing security review.
Run a structured code-review pass on a pull request or branch, applying the Tyrne code-review standard.
