Conciseness

The body is a lean control-flow document with no padding or explanations of known concepts, but there is minor duplication: the read-the-reference-first rule appears in both 'Phase references' and 'Rules', and the non-repairing boundary is stated in step 1 and again in Rules. That repetition keeps it at anchor 4 rather than 5.

Actionability

Guidance is concrete and executable for an instruction-only skill: an explicit dispatch table, exact status branches ('blocked', 'failed', 'validated') each with a defined action and stop, input handling rules, and a concrete example ('$sce-validate my-plan'). It stops short of anchor 5 only because the executable validation detail is delegated to references rather than fully self-contained.

Workflow Clarity

The sequence is explicit with validation gates throughout: branch-on-Status checkpoints, hard stops per outcome, a blocked guard when implementation tasks remain, and a fix-then-rerun feedback loop preserving the '/validate {plan-path}' retry instruction on failure. This matches the 'clear sequence with explicit validation steps and feedback loops' anchor.

Progressive Disclosure

SKILL.md is a control-flow overview that splits phase detail into three real, directly-referenced files (references/validation.md, references/validation-report.md, references/output.md), each signaled with when to read it ('Read the reference before taking any action for step 1'; validation-report.md is pointed to 'at the moment it is needed'). All references are one level deep and every referenced path exists in the bundle, matching the clear-overview anchor.

Specificity

The description names the domain and two concrete actions — 'Validate one completed SCE plan' and 'record final validation evidence' — matching the '1-2 concrete actions, but not comprehensive' anchor. It is not a 4 because it does not list several specific actions (no mention of running validation commands, checking acceptance criteria, or writing a report).

Completeness

It clearly answers 'what' (validate a completed SCE plan and record evidence) but contains no 'Use when...' clause or equivalent trigger guidance, capping completeness at 3 per the judging guidelines. Not a 2 because the 'what' is clear and specific rather than vague.

Trigger Term Quality

Relevant keywords exist ('Validate', 'SCE plan', 'validation evidence') but common variations users would naturally say are missing ('check the plan', 'verify the plan', 'final check', 'plan done'). It clears anchor 3 ('some relevant keywords but missing common variations') without reaching anchor 4's 'good keyword coverage'.

Distinctiveness Conflict Risk

The niche is clear — final validation of a completed SCE plan — making it mostly distinct with only minor overlap risk against sibling SCE workflow skills and generic 'validate' phrasing. Not a 5 because 'Validate' alone could collide with non-SCE validation requests, and the description does not carry fully distinct trigger phrases.
