Conciseness

Lean body with no padding of concepts Claude already knows; every section (preflight, per-task loop, failure table, models) earns its place, and non-obvious Grok-specific facts like '--always-approve is required for headless runs' justify their inclusion.

Actionability

Fully executable guidance with copy-paste-ready commands for both POSIX and Windows (grok --prompt-file ... --output-format json --always-approve --max-turns 30 --cwd <repo>, grok --resume, git checkout -- .) and a concrete task spec template.

Workflow Clarity

Clearly sequenced per-task loop with an explicit, non-negotiable review gate, validation checkpoints (read the diff, run acceptance commands), a bounded fix-up feedback loop (max 2 rounds), and a revert fallback — satisfying the destructive/batch validation requirement.

Progressive Disclosure

SKILL.md serves as a tight overview that signals one-level-deep references to the confirmed references/cli.md ('Full CLI details and verified behaviors: references/cli.md'), keeping detail out of the main body while remaining easy to navigate.

Specificity

Lists multiple concrete orchestrator actions ('plans, writes the task specs, reviews every diff, and owns the result', 'Executes a Markdown implementation plan task-by-task') with comprehensive coverage of the delegation workflow.

Completeness

Explicitly answers both 'what' (orchestrates coding work by delegating to Grok Build headlessly, planning, reviewing, owning results) and 'when' (an explicit 'Use when user says:' clause with concrete trigger phrases).

Trigger Term Quality

Provides comprehensive natural trigger phrases users would actually say ('use grok', 'grok build', 'delegate to grok', 'have grok implement', 'send to grok', 'execute this plan with grok') including synonyms and variations.

Distinctiveness Conflict Risk

Clear niche (delegating to xAI's Grok Build CLI) with Grok-specific trigger phrases that are unlikely to fire for unrelated skills, giving minimal conflict risk.
