Lists multiple specific concrete actions: capture architectural decisions, auto-detect decision moments, record context/alternatives/rationale, and maintain an ADR log. These are clear, actionable capabilities.

The 'what' is well-covered with specific capabilities, but there is no explicit 'Use when...' clause or equivalent trigger guidance. The 'when' is only implied through the description of what it does, which per the rubric caps completeness at 2.

Includes good terms like 'ADR', 'architectural decisions', 'rationale', and 'alternatives considered', but misses common user phrasings like 'architecture decision record', 'design decision', 'document why', or 'decision log'. Users might not naturally say 'ADR' if they don't know the acronym.

ADRs (Architecture Decision Records) are a very specific niche. The description clearly targets structured architectural decision documentation, which is unlikely to conflict with general documentation, code review, or other development skills.

The skill is reasonably well-structured but includes some unnecessary content that Claude already knows — the 'What Makes a Good ADR' do/don't list, the categories table, and the lifecycle explanation are somewhat verbose. The ADR format template includes placeholder commentary ('What is the issue...', 'What is the change...') that adds bulk without value.

The skill provides a concrete, copy-paste-ready ADR template, a specific directory structure, a concrete index format, explicit detection signals, and clear step-by-step workflows for both creating and reading ADRs. The guidance is specific and directly executable.

Both the 'Capturing a New ADR' and 'Reading Existing ADRs' workflows are clearly sequenced with numbered steps. Importantly, there are explicit confirmation/validation checkpoints — step 1 requires user confirmation before creating directories, step 7 requires explicit approval before writing, and the reading workflow has clear branching for missing ADRs. The implicit signals section explicitly states 'do not auto-create without user confirmation.'

The content is well-organized with clear section headers, but it's a fairly long monolithic document (~150 lines of substantive content). The categories table, lifecycle section, and 'What Makes a Good ADR' guidelines could be split into a reference file. The brief 'Integration with Other Skills' section at the end is appropriately concise, but overall the skill inlines content that could benefit from separation.
