Conciseness

The body is lean, using compact tables (domain/signal mapping, quick commands) and templates without explaining concepts Claude already knows. It earns a 4 rather than 5 because the 'Expert Structure Requirements' section repeats the directory structure already shown in step 2, and the 'Signal Mode' section re-states the validate/register commands from step 6.

Actionability

Concrete, executable commands are given ('scripts/validate_expert.sh /path/to/expert-{name}', 'scripts/register_expert.sh /path/to/expert-{name}') along with a copy-paste example prompt, a directory template, and a frontmatter template. It falls short of level 5 because steps 3-4 rely on placeholder templates ('{topic-1}.md', '{helper}.sh') and delegate script content to reference files without showing even one worked example inline.

Workflow Clarity

Seven clearly numbered steps run from input analysis to reporting, with an explicit validation checkpoint ('Run validation... If valid, register') backed by a Validation Checks list, so no destructive/batch cap applies. It is not level 5 because the error-recovery loop is one-sided: it never states what to do when validation fails (fix and re-run), and registration reporting of line numbers is mentioned without a re-check step.

Progressive Disclosure

The SKILL.md is a clear overview that splits detail into well-signaled, one-level-deep references ('See references/expert-structure.md', 'references/catalog-formats.md', 'references/signal-patterns.md'), all of which exist in the bundle alongside the referenced scripts (validate_expert.sh, register_expert.sh). This matches the anchor for a clear overview with well-signaled one-level-deep references and easy navigation.

Specificity

Quotes like 'Automatically synthesizes references, generates signal scripts, validates, and registers in experts.md/signals.md catalogs' list several concrete actions covering the full pipeline, matching the anchor for several specific actions with minor gaps. The imperative sentence 'Provide a markdown file path with domain knowledge + optional steering context' is second-person voice rather than third person, so the +1 voice penalty is applied to an otherwise level-5 capability list.

Completeness

The 'what' is explicit ('creating new SDD experts from domain documentation... synthesizes references, generates signal scripts, validates, and registers') and the 'when' is explicit via the concrete 'Triggers - create expert, new expert, make expert...' clause, an explicit trigger-guidance equivalent of a 'Use when...' clause. This clearly matches the anchor for explicitly answering both what and when with concrete trigger phrases, not the level-4 anchor where the 'when' is weaker or less specific.

Trigger Term Quality

'Triggers - create expert, new expert, make expert, expert for, domain expert, add expert' gives good coverage of natural verb variations users would say. It misses a few natural terms such as 'SDD expert', 'generate expert', or 'expert from docs', matching the 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive-synonyms anchor at 5.

Distinctiveness Conflict Risk

The niche is distinct ('Meta skill for creating new SDD experts from domain documentation' with catalog registration in experts.md/signals.md) and its triggers ('create expert', 'domain expert', 'add expert') point unambiguously to this creator skill. It matches the 'clear niche with distinct triggers; minimal conflict risk' anchor; no neighboring anchor fits better since no other skill in this system would claim expert-creation phrases.
