Grok Archive Record

• Archived: 2026-08-20
• Review deadline: 2026-11-18
• Capability owner: builder
• Alternatives: Builder (parser implementation), Sentinel (ReDoS audit), Shift (AST codemods), Radar (grammar fuzzing)

Reason

grok had zero inbound COLLABORATION_PATTERNS partners and zero peer SKILL.md mentions; its capabilities are owned by Sentinel (ReDoS), Shift (AST transformation), Builder (implementation) and Radar (fuzzing). The archived directory preserves the pre-sunset definition for the 90-day recovery window.

Restore

1. Confirm grok/ does not already exist.
2. Move .archive/grok/ back to grok/.
3. Remove this archive record from the restored directory.
4. Revert the absorbed capabilities in builder/SKILL.md only after verifying no newer work depends on them.
5. Restore routing (nexus/reference/routing-matrix.md, agent-disambiguation.md), pack (_common/SKILL_PACKS.md), profile (~/.claude/profiles/*.json), boundary (_common/BOUNDARIES.md) and catalog (compass/reference/catalog.md) entries.
6. Run lint-frontmatter.py, lint-instructions.py, and validate-recipes.py.

Do not delete this archive before the review deadline unless the restoration decision has been documented.
