Conciseness

The ~430-line body is mostly useful but redundant: immutability/superseding is stated three times (the ADR-vs-RFC table, the 'Editing Instead of Superseding' anti-pattern, and 'Important Notes' — 'ADRs are immutable — never edit the decision'), language adaptation appears twice ('Language Adaptation' section and the notes), and 'Example Prompts that Trigger This Skill' repeats the frontmatter triggers in three languages. It is not a 2 — there is no padded explanation of basic concepts — but it clearly exceeds 'minor instances that could be trimmed'.

Actionability

The body is fully executable for a document-generation skill: three complete fill-in templates (MADR, Nygard, Y-Statement), explicit mandatory/recommended field lists ('Decision title… Date… Status… Context… decision itself… Consequences'), a concrete directory-scanning procedure for numbering ('Find the highest existing number… if ADR-007 exists, this becomes ADR-008'), naming conventions with a directory tree, and BAD/GOOD before/after examples for each anti-pattern. This covers the common cases copy-paste ready.

Workflow Clarity

A clearly sequenced 5-step workflow (gather context → validate mandatory fields → assign number → generate → offer placement) with explicit checkpoints: Step 2 mandates asking for missing mandatory fields 'in the user's language before generating', and the 'ADR Quality Checklist' verifies the output before finalizing. Not a 4 — the validation checkpoints are explicit, not merely implicit in the sequence.

Progressive Disclosure

The body is well-sectioned with clear headers, so navigation is possible, but it is a single ~430-line file with no bundle files: the three full templates, the anti-pattern BAD/GOOD examples, and the multi-language trigger examples are natural candidates for references/ files that would keep SKILL.md an overview. This matches the 3 anchor ('some structure… content that should be separate is inline') rather than 4, where most content would be appropriately placed across files.

Specificity

The description names concrete actions — 'Creates Architecture Decision Records (ADRs) to document significant architectural choices and their rationale for future team members' — going beyond naming the domain. It falls short of 5 because the skill is single-artifact, so it lists create/document/capture-reasoning rather than the multiple distinct concrete actions of the 5-anchor example.

Completeness

It explicitly answers both 'what' ('Creates Architecture Decision Records (ADRs) to document significant architectural choices and their rationale for future team members') and 'when' ('Use when the user says… or wants to capture the reasoning behind a technical choice'), plus explicit do-not-use boundaries. This matches the 5 anchor with concrete trigger phrases; nothing is only implied.

Trigger Term Quality

Quote: 'Use when the user says "write an ADR", "document this decision", "record why we chose X", "add an architecture decision record", "create an ADR for"' — these are the exact natural phrasings a user would say, with no common variation or synonym missing. It clearly exceeds the 4 anchor ('a few natural terms missing').

Distinctiveness Conflict Risk

The niche is clear (ADR creation for decisions already made) and it explicitly diverts adjacent cases: 'Do NOT use when the decision hasn't been made yet (use create-rfc instead), for implementation planning (use technical-design-doc-creator), or for general documentation.' Distinct triggers and named neighboring skills give minimal conflict risk.
