Conciseness

The body is mostly efficient operational guidance but includes padding that could be tightened — notably the run-on Phase 2 paragraph and repeated explanations of 'devflow's wrapper around the upstream executing-plans skill' — so it sits at the mostly-efficient-but-could-tighten 3 anchor rather than the leaner 4.

Actionability

Provides fully executable bash (worktree recovery, branch-slug sanitizing, git status checks), exact file paths, concrete AskUserQuestion option strings, a literal regex, and a copy-paste Test Inventory markdown template covering the common cases, matching the score-5 anchor.

Workflow Clarity

Phases are explicitly sequenced with validation checkpoints — Phase 1.5 verifies each test fails for the right reason with acceptable/unacceptable failure modes, Phase 1.8 is a mandatory approval gate, Phase 0 checks git cleanliness, and the 'Important' section is a checklist — satisfying the batch/destructive feedback-loop requirement and the score-5 anchor.

Progressive Disclosure

The skill is a single self-contained file with no bundle references and clear phase-based section structure, avoiding nested references; it lands at 4 because organization is good and content is appropriately placed, though some inline material (the constraints table, the inventory template) could conceivably be split out, keeping it below the ideal one-level-deep reference structure of 5.

Specificity

Lists multiple specific concrete actions — 'Lock the full test inventory', 'Reads spec+plan+AC', 'writes ALL failing tests in a batch', 'emits a Test Inventory doc', and 'gates with user approval' — giving comprehensive coverage of the workflow, matching the score-5 anchor rather than the score-4 anchor which expects minor gaps.

Completeness

Clearly states what the skill does but lacks an explicit 'Use when...' trigger clause; 'before any implementation code is written' is a sequencing hint, not a trigger, so per the missing-trigger cap it cannot exceed 3 even though the 'what' is strong.

Trigger Term Quality

Contains good natural keywords a pipeline user would say ('test inventory', 'failing tests', 'user approval', 'spec+plan+AC') but leans on internal jargon and misses common synonyms, placing it above the score-3 anchor yet short of the comprehensive synonym/extension coverage expected at 5.

Distinctiveness Conflict Risk

The 'lock-tests' / 'Test Inventory doc' / 'user-approval gate' framing carves a fairly distinct niche with low conflict risk, but it overlaps with broader TDD skills enough to land at 4 rather than the minimal-conflict 5 anchor.
