Tooling Compatibility Matrix

Tooling Compatibility Matrix

Offline baseline for hardening and high or critical refactor tooling recommendations. This skill never fetches versions. Every emitted version must include verify-latest-at-execution: true and an executor task to verify that the chosen version is current and CVE-free before installation.

Standing rules

• Prefer existing project conventions when present.
• Use this matrix for deterministic first-pass versions and compatibility notes.
• Pair every install task with a build verification command.
• If a version or plugin compatibility is uncertain, mark it as hypothesis and require verification before install.
• Web fetch remains denied for harness workers.
