Conciseness

The core operational content is dense and efficient (exact git commands, tight safety rules), but generic boilerplate sections pad it out — 'Use this skill when', 'Do not use this skill when', an 'Instructions' section of placeholders like 'Clarify goals, constraints, and required inputs', and a 'Limitations' section that repeat nothing skill-specific. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened'; a 2 would require several padded explanatory sections throughout, whereas here the padding is confined to a few template blocks.

Actionability

The guidance is largely executable: concrete commands such as `git log --oneline --grep="{trackId}" --grep="Task {X.Y}" --all-match` and `git revert --no-edit abc1234`, exact argument formats, exact confirmation protocol, and precise marker updates. Minor gaps remain — `{test command}` and 'Check application: {relevant check}' placeholders, and steps like 'Determine task range for the phase by reading plan.md' given without a command — placing it at 'mostly executable guidance with minor gaps' rather than fully copy-paste ready (5).

Workflow Clarity

The multi-step destructive workflow is fully sequenced with explicit validation checkpoints and feedback loops: pre-flight repo/cleanliness checks, a full execution plan displayed before any operation, mandatory explicit 'YES' confirmation, immediate HALT on any conflict with user options, and post-revert verification with recovery guidance. This matches the top anchor 'clear sequence with explicit validation steps; feedback loops for error recovery' — the destructive-operation cap is clearly satisfied.

Progressive Disclosure

The single-file body (no bundle files exist) is well organized with clearly labeled sections in logical order (pre-flight, selection, discovery, plan, execution, updates, verification, edge cases), each independently navigable. It fits 'good structure; most content is appropriately placed; minor organization gaps' — not a 5 because the ~376 lines include long inline dialog templates (menus, ASCII plan boxes, edge-case screens) that could be split into reference files, though nothing is buried or nested.

Specificity

The description names the domain ("Git-aware undo") and one concrete capability ("by logical work unit (track, phase, or task)"), but does not enumerate the actual operations (commit discovery, execution planning, plan.md updates, verification). It matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'; a 4 would require several specific actions listed, which is not the case.

Completeness

The 'what' is clear (git-aware undo at track/phase/task granularity), but there is no 'Use when...' clause or equivalent trigger guidance — 'Git-aware' only weakly implies the 'when'. Per the judging guidelines, a missing 'Use when...' clause caps completeness at 3; not a 4 because the 'when' is absent rather than present-but-imprecise.

Trigger Term Quality

It includes some relevant natural keywords ("Git", "undo", "track, phase, or task"), but misses the most common phrases a user would say for this task — "revert", "roll back", "undo my last commit/task" — leaving keyword coverage at 'some relevant keywords but missing common variations or synonyms'. Not a 2, since 'Git' and 'undo' are genuine natural terms rather than generic filler.

Distinctiveness Conflict Risk

The '(track, phase, or task)' vocabulary ties it to a distinct Conductor-style workflow system, making it mostly distinguishable; however, 'Git-aware undo' broadly overlaps with any generic git revert/undo skill, so minor conflict risk remains. It sits above 'could still overlap with similar skills' (3) and below 'clear niche with distinct triggers' (5) because the trigger phrases themselves are not distinctive.
