Conciseness

The body is purposefully structured but ~340 lines with padding that Claude doesn't need (ASCII art diagrams, a full example Mermaid graph, a sample session flow, an inspirational closing quote, and some generic mental-model framing). Matches 'mostly efficient but includes some unnecessary explanation or could be tightened'. Not a 2 because the structure is intentional, not heavily padded; not a 4 because several sections (ASCII fallback, example session flow, closing quote) could be trimmed.

Actionability

Provides concrete, reusable output templates (Project Overview, Deep Dive, Where to Next scaffolds), real Mermaid/ASCII diagram examples, and question-pattern tables, matching 'mostly executable guidance; concrete code or commands with minor gaps'. Not a 5 because templates rely on illustrative placeholders like [One sentence description] rather than being copy-paste-ready for a specific task; not a 3 because the guidance is well beyond pseudocode.

Workflow Clarity

Four clearly sequenced phases (First Impressions -> Architecture -> Focused Exploration -> Follow-Up) each with numbered sub-steps and a worked example flow, matching 'clear sequence with most checkpoints present'. Not a 5 because checkpoints (assess familiarity, set context) are implicit rather than explicit validation steps; not a 3 because the sequence is genuinely clear and well-defined, not merely 'steps listed'.

Progressive Disclosure

Good section structure and one-level-deep references to diagram-patterns.md and interaction-template.md, but neither referenced file exists in references/, scripts/, or assets/, so the signaled navigation is broken and several full output-format/ASCII blocks arguably belong in those files rather than inline. Matches 'references present but not clearly signaled; content that should be separate is inline'. Not a 4 because missing referenced files are more than a minor gap; not a 2 because real structure and signaled references are present.

Specificity

Lists several concrete actions ('Produces high-level overviews with diagrams, drills into details on request, and offers follow-up exploration questions'), which matches the 'several specific actions; minor gaps' anchor. Not a 5 because the actions are somewhat abstract rather than razor-sharp concrete operations; not a 3 because it clearly enumerates more than 1-2 actions.

Completeness

Explicitly answers both what ('Simulates plan mode with a teaching-first approach... Produces high-level overviews with diagrams, drills into details on request, and offers follow-up exploration questions') and when ('Use when onboarding to a new codebase, exploring architecture, or seeking guided understanding'), with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Includes natural phrases users would say ('onboarding to a new codebase', 'exploring architecture'), matching 'good keyword coverage; a few natural terms missing'. Not a 5 because common synonyms ('codebase tour', 'walk me through', 'code review prep') are absent; not a 3 because coverage is broader than 'some relevant keywords'.

Distinctiveness Conflict Risk

'Simulates plan mode with a teaching-first approach' carves a fairly distinct teaching/onboarding niche, matching 'mostly distinct; minor overlap risk'. Not a 5 because 'guided understanding of any project area' is broad and could overlap with general explanation skills; not a 3 because the framing is clearly more specific than generic document/code helpers.
