Conciseness

Every step is a one-line instruction plus the exact command ('git rev-parse --show-toplevel', 'command -v greptile', 'greptile review --json'), with zero padding and no explanation of concepts Claude already knows. Matches the 'lean and efficient; every token earns its place' anchor; level 4 would require trimmable over-explanation, which is absent.

Actionability

Fully executable, copy-paste-ready commands at every step, including the npm install, the curl shell-installer fallback, and the '--agent' fallback when '--json' fails. Matches the level-5 anchor covering the common cases; not 4 since no key executable detail is missing.

Workflow Clarity

Clear five-step sequence with explicit checkpoints and feedback loops: failure handling at repo check, CLI presence, auth ('Wait for the user to complete the login flow'), a fallback command on usage error, and 'Do not hide the raw command failure if both commands fail' for error recovery. Not a destructive or batch operation, so the level-3 cap does not apply; matches the level-5 anchor.

Progressive Disclosure

Well-organized into five clearly headed sections with nothing that warrants splitting into separate files, and no buried or nested references. Held at 4 rather than 5 because the body (~83 lines) exceeds the under-50-line threshold where flat structure alone earns top marks, and no reference-based organization is demonstrated.

Specificity

Lists several concrete third-person actions — 'Runs a Greptile CLI review for the current local branch, installing or authenticating the CLI when needed, then summarizes JSON findings' — with only minor gaps (e.g., the git-repo requirement and plain-text fallback are unstated). Not 5 because coverage of the skill's behaviors is not exhaustive; not 3 because it clearly exceeds 1-2 actions.

Completeness

Explicitly answers both: what ('Runs a Greptile CLI review... installing or authenticating the CLI when needed, then summarizes JSON findings') and when ('Use when the user wants Greptile feedback before opening a PR, outside a hosted PR review flow, or directly from a local checkout') with concrete trigger phrases. Matches the level-5 anchor; level 4 would require a less explicit 'when' clause.

Trigger Term Quality

Contains natural phrases users would actually say: 'Greptile feedback before opening a PR', 'outside a hosted PR review flow', 'directly from a local checkout'. Not 5 because a few natural variants (e.g., 'AI code review', 'review my diff', 'pre-PR check') are missing.

Distinctiveness Conflict Risk

Clearly niched to the Greptile CLI and explicitly distinguishes itself from 'a hosted PR review flow', giving it distinct triggers with minimal conflict risk against generic code-review skills. Matches the level-5 anchor.
