Conciseness

The body is dense and instructional with no explanations of concepts Claude already knows, but re-entry guidance is duplicated between Step 7's "Re-entry" section and the "Safety & Fallback" section, and "Critical Constraints" repeats Step 7's CRITICAL warning — some unnecessary repetition that could be tightened. Not a 2 because padding is limited; not a 4 because the duplication goes beyond minor.

Actionability

Provides fully executable, copy-paste-ready guidance: exact file paths ({{KIRO_DIR}}/specs/<feature-name>/brief.md), complete brief.md and roadmap.md templates, per-path next commands ($kiro-spec-init, $kiro-spec-batch, $kiro-spec-requirements), and specified sub-agent return formats ("findings under 200 lines", "Return only issues found, or 'No issues found'"). Concrete specifics cover the common cases for every path.

Workflow Clarity

A clear 8-step sequence with explicit path branching (A–E), user-confirmation checkpoints ("present the determined path... and confirm before proceeding"), a viability-check feedback loop ("If the viability check reveals issues... revisit the approach selection"), and write verification ("verify the files exist by reading them back"). Not a 5 because the read-back verification lacks an explicit recovery loop if it fails and a few checkpoints remain implicit.

Progressive Disclosure

No bundle files exist and none are referenced, so there are no broken or nested references; sections are well-organized (numbered steps, Critical Constraints, Safety & Fallback) and the templates are consumed exactly once at write time, making inlining defensible. Minor gap: the ~90 lines of brief/roadmap templates could arguably live in a references/ file, keeping SKILL.md as a leaner overview.

Specificity

Enumerates concrete decision outcomes — "update existing spec, create new spec, mixed decomposition, or no spec needed" — plus a second action ("refines ideas through structured dialogue"), matching the several-specific-actions-with-minor-gaps anchor. It falls short of 5 because "refines ideas through structured dialogue" is generic phrasing rather than a fully concrete capability.

Completeness

The "what" is clear (determines action path/decomposition and refines ideas) and a "when" is explicitly stated via "Entry point for new work", so the missing-trigger cap does not apply; however the trigger guidance is terse and could be more specific, matching the both-present-but-when-could-be-more-explicit anchor. Not a 5 because there are no concrete trigger phrases like "Use when...".

Trigger Term Quality

Contains some relevant keywords users might say ("new work", "spec", "decomposition") but misses common natural variations like "new feature", "idea", "plan", or "break this down", matching the some-relevant-keywords-missing-variants anchor. Not a 4 because more than just a few natural terms are absent.

Distinctiveness Conflict Risk

The repeated "spec" terminology carves out a niche, but the broad opening "Entry point for new work" and "refines ideas through structured dialogue" overlap with general planning/brainstorming skills, matching the somewhat-specific-but-still-overlapping anchor. Not a 4 because the overlap risk with closely related planning/ideation skills is more than minor.
