Conciseness

The 16-line body is lean with no padding: every sentence instructs ("Each option gets one line on why it lost", "A consequence is something that will cost effort or close a door, not a benefit restated") or sets the output quality bar ("a record a newcomer can read a year later"). Nothing re-explains concepts Claude already knows, so it fits the lean anchor rather than the minor-trimming anchor 4.

Actionability

Guidance is fully concrete and executable: the exact activation command ("uv run {project-root}/_bmad/scripts/resolve_config.py --project-root {project-root} --key core.output_folder --key core.active_initiative"), the exact fallback ("npx skills add bmad-code-org/BMAD-METHOD --skill bmad"), the precise output path pattern with its unset edge case, and named sections with per-item rules. As an instruction-only skill with copy-paste-ready commands, it matches the top anchor.

Workflow Clarity

The sequence is unambiguous: activate config (with a script-not-found fallback), mine the conversation, ask one question at a time, write four sections, "Show the draft and wait", then write the file on approval and tell the user the path. The approval gate is an explicit checkpoint and the activation fallback is an error-recovery loop; the operation is non-destructive so no validation cap applies.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and has no bundle files (references/, scripts/, assets/ are absent), so there is nothing to push to separate files. The two clear sections ("On activation", "Writing the record") are well organized, which per the simple-skill guidance earns the top score.

Specificity

"Writes an architecture decision record (ADR)" names the domain plus one concrete action, matching the anchor for 1-2 concrete actions that are not comprehensive. It is more concrete than the generic anchor 2 ("Processes PDF files") but does not list several specific actions needed for anchor 4.

Completeness

It clearly states what the skill does ("Writes an architecture decision record (ADR)") and explicitly when to use it with concrete quoted trigger phrases ("Use when the user says..."). This matches the anchor requiring both what and when with concrete trigger phrases.

Trigger Term Quality

The quoted phrases "record this decision", "write an ADR" and "we decided X, capture it" are natural things a user would say, and the full term plus acronym ("architecture decision record (ADR)") is present. A few natural synonyms such as "decision log" or "document this decision" are missing, so it falls just short of the comprehensive anchor.

Distinctiveness Conflict Risk

The ADR niche is clear and "write an ADR" is unambiguous, but the softer triggers "record this decision" and "capture it" could plausibly overlap with general note-taking or documentation skills. Mostly distinct with minor overlap risk, fitting anchor 4 rather than the minimal-conflict anchor 5.
