Conciseness

The body is lean and assumes Claude's competence: hard rules, a decision-gate table, and a numbered execution list with no padding or explanation of concepts Claude already knows. Every line (thresholds, markers, tracker rules) earns its place, matching the anchor-5 'lean and efficient' example. It is not 4 because there are no noticeable instances of over-explanation to trim.

Actionability

Concrete numeric thresholds (400 changed lines, ≤60 minutes), explicit rules (📍 marker, draft/no-merge tracker), and a condition→action decision table give mostly executable guidance, with commands and PR-body templates deferred to the one reference. It is below 5 because executable commands/templates are not inline in SKILL.md itself, and above 3 because the guidance is specific and concrete rather than pseudocode-level.

Workflow Clarity

Execution steps are clearly sequenced (1–6) with an explicit validation checkpoint in step 5 ('Verify each PR independently: CI/tests/docs manual checks, rollback scope, and clean diff') and a feedback notion in the Hard Rules ('retarget or rebase until only the current work unit appears'). This matches the anchor-5 'clear sequence with explicit validation steps; feedback loops for error recovery' for batch/PR operations. It is not 4 because validation is explicit rather than only mostly present.

Progressive Disclosure

The body is a clear overview that points to a single, real, one-level-deep reference (references/chaining-details.md, verified to exist) with a one-line description of its contents; diagrams, commands, and templates are appropriately split out. This matches the anchor-5 'clear overview with well-signaled one-level-deep references; easy navigation'. It is not 4 because the split is clean with no organization gaps.

Specificity

Names the domain ('chained PRs') and 2 concrete actions ('Split oversized changes', 'protect review focus') but does not enumerate the several strategies (stacked, feature-branch chain, tracker) that the body covers, so coverage is not comprehensive. It is above 2 (more than minimal) but below 4 (does not list several specific actions).

Completeness

Explicitly answers 'what' ('Split oversized changes into chained PRs that protect review focus') and 'when' via an explicit 'Trigger:' clause with concrete trigger phrases (PRs over 400 lines, stacked PRs, review slices), matching the anchor-5 pattern of clearly answering both what and when. It is not 4 because the 'when' is concrete rather than only weakly specified.

Trigger Term Quality

Natural user-facing phrases are present ('PRs over 400 lines', 'stacked PRs', 'review slices', 'chained PRs') with good coverage of how users phrase the need. It falls short of 5 because common synonyms like 'review load' or 'stacked' phrasings are not exhaustive, and above 3 because several genuine natural terms appear.

Distinctiveness Conflict Risk

It carves a clear niche (oversized/stacked/chained PRs and review-focus control) with distinct triggers unlikely to fire for unrelated skills, matching the anchor-5 'clear niche with distinct triggers; minimal conflict risk'. It is not 4 because the trigger is narrowly scoped rather than having residual overlap with closely related skills.
