Conciseness

The body is lean, assumes Claude knows what ADRs are, and provides only project-specific rules and context (e.g., the git date-verification command, the TRaSH Guides/Recyclarr relationship). Minor over-explanation remains: the 'Reasons:' bullet list under Attribution and parts of the Perspective section justify rules rather than state them. Not 5 because those passages could be trimmed; not 3 because padding is minor and most content is knowledge Claude lacks.

Actionability

Concrete, executable guidance throughout: template paths, the 'NNN-kebab-case-title.md' naming pattern, a copy-paste git command ('git log --format="%ai" <commit> -1'), a complete reference-style-link example, and enumerated status values. Minor gaps: how to determine the next sequential NNN is left implicit, and no sample decision document is shown inline (mitigated by the mandatory template reads).

Workflow Clarity

The sequence is clear and well-ordered — MANDATORY template read first, then rules (naming, dates, links), status selection, and ADR-vs-PDR scoping — with a real checkpoint ('ask the user for one before finalizing the PDR'). Not 5 because the workflow is organized as rule sections rather than an explicit ordered procedure, so checkpoints are implicit rather than listed; not 3 because the mandatory template gate and upstream-link gate function as validation for this document-writing task.

Progressive Disclosure

No bundle files exist, and the ~90-line body is appropriately self-contained: well-organized sections with clear headers, and the only external materials (the ADR/PDR templates) are clearly signaled one-level-deep references marked MANDATORY. Content that would warrant splitting (the templates) already lives outside the body, so navigation is easy.

Specificity

The description enumerates multiple concrete actions — 'creating, editing, superseding, or reviewing' ADRs/PDRs, 'writing MADR-formatted decision documents', 'recording rationale', 'linking a decision to a TRaSH Guides upstream source', 'changing a decision's status' — with comprehensive coverage of the skill's scope. Not 4 because coverage is complete rather than having minor gaps.

Completeness

Both 'what' (the enumerated create/edit/supersede/review actions) and 'when' (an explicit 'Use when' clause plus a 'Triggers on phrases like' list) are clearly stated with concrete trigger phrases. Matches the top anchor exactly.

Trigger Term Quality

Provides comprehensive natural trigger phrases ('write an ADR', 'new PDR', 'document this decision', 'decision record', 'add an architecture decision') plus synonyms (ADR/PDR expansions) and file-path patterns ('docs/decisions/**/*.md'). A user needing this skill would naturally say one of these.

Distinctiveness Conflict Risk

Clear niche (decision records under docs/decisions/) with distinct triggers, and an explicit exclusion — 'Do NOT use for general architecture documentation under docs/architecture/' — that minimizes conflict risk with adjacent documentation skills.
