Conciseness

The body is lean and imperative throughout — "Pass the brief verbatim. Do not restate, summarize, or reinterpret it" — with no explanation of concepts Claude already knows. It falls short of 5 because the Rules section restates several directives already given inline (e.g., step 3's "Offer revision, but do not gate the handoff on it" vs. "Do not gate the handoff on open questions listed in the plan summary"), and the justificatory prose in step 3 ("The plan was written from one prose request, so its assumptions are guesses...") could be trimmed.

Actionability

For an instruction-only skill the guidance is fully executable: every step names its reference file, every branch is keyed to an explicit status value ("bootstrap_required", "needs_clarification", "blocked", "plan_ready"), output rendering points to named layouts with exact fields ("Use the question's `id`, `category`, `question`, and `why_blocking` fields exactly as returned"), and even string-level edits are specified ("replacing `is ready` with `revised` in the heading"). Placeholders like {plan-path} are tied to concrete resolution rules ("the path resolved in step 2 (`plan.path`, or an entry of `candidates`)"), so every emitted command is directly runnable.

Workflow Clarity

The four-step sequence is explicit with numbered steps, ordered gates, and unambiguous stops and waits ("Stop and wait. Do not implement, and do not run the handoff yourself"). Validation checkpoints are present as explicit branch gates at every phase boundary, the bootstrap wait has a defined re-entry path ("When they report the command ran, run the **Context load phase** again and continue in this session"), step 4 defines a full revision feedback loop, and the Rules section acts as a checklist. No destructive or batch operations are performed by this skill itself.

Progressive Disclosure

The bundle structure matches the body exactly: all four files in `references/` (context-load.md, plan-authoring.md, output.md, plan-template.md) are explicitly cited, each mapped to the step that needs it via the step table, with load timing specified ("Read a step's reference before taking any action for that step, not after") and over-loading explicitly prevented ("Read only the reference for the step you have reached"). References are one level deep and the control flow stays in SKILL.md while phase detail lives in the references — a clean overview-plus-detail split with easy navigation.

Specificity

The description names the domain ("SCE plan") and one concrete action ("Turn one change request into a scoped SCE plan"), which matches the 1-2-concrete-actions anchor. It is not a 4 because it does not list several specific actions or sub-capabilities (e.g., clarification gates, plan revision), and not a 2 because the single action it names is concrete rather than generic.

Completeness

The "what" is clear ("Turn one change request into a scoped SCE plan"), but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not a 4 because the "when" is entirely absent rather than merely under-specified.

Trigger Term Quality

Relevant keywords are present ("change request", "scoped", "plan"), but common variations a user would naturally say — "planning", "roadmap", "break this change down", "implement" — are absent. It is above a 2 ("one or two generic keywords") because the terms are domain-relevant rather than generic, but below a 4 because natural phrasing coverage is thin.

Distinctiveness Conflict Risk

The "SCE" namespace and "one change request into a scoped plan in one self-contained workflow" framing carve a fairly distinct niche with clear scope limits. It is not a 5 because without a when-clause, generic planning or implementation requests could still plausibly route here over related skills.
