Conciseness

The body is dense and assumes competence — no concept explanations, no padding, with specifics like "One transcript line can be a megabyte" and "gh cannot attach files" earning their tokens. It falls short of 5 because the Red Flags table restates several Hard rules almost verbatim (e.g., reconstructing the partner's statement away, and building the bundle only when asked), which could be consolidated.

Actionability

Guidance is highly concrete: exact file paths ("~/.superpowers/diagnosing-superpowers/<session-id>/"), commands ("zip -r" / "tar -czf"), named analyst dimension files, and explicit approval gates. It is not a 5 because many of the executable artifacts it depends on (templates/case.md, templates/report.md, prompts/analyst-common.md, prompts/scrub.md, etc.) are referenced but absent from the bundle, so the workflow cannot actually be executed as shipped.

Workflow Clarity

Seven steps are clearly sequenced with explicit conditional execution ("Steps 5–7 run only on their stated condition"), and validation is built in throughout: findings without path:line are discarded, the scrub/audit loop repeats "until the audit returns CLEAN", and hard approval gates precede archiving and issue creation. This matches the anchor with feedback loops and checkpoints for a complex process.

Progressive Disclosure

The in-body structure is well designed — a lean overview pointing one level deep to references/, templates/, and prompts/ — but scored against the actual bundle, 11+ of the referenced paths (all of templates/ and prompts/) do not exist, and references/redaction-policy.md exists yet is never referenced in the body. Navigation fails for most pointers, which is worse than the minor organization gaps of a 3.

Specificity

The description names its domain ("a superpowers session went wrong") and one to two concrete actions ("wants to know why" and "build a bug report for the superpowers maintainers"), but most of its length is trigger symptoms rather than what the skill actually does (e.g., reading transcripts or reporting with evidence is never stated). It is not a 4 because the lists of complaints ("repeated work, ignored plans, stumbles...") are triggering conditions, not capabilities of the skill.

Completeness

Both 'when' and 'what' are present and the trigger guidance is explicit ("Use when...") with concrete trigger phrases. It is not a 5 because the 'what' is thinner than the 'when': diagnosing is implied through the complaint list rather than explicitly stating the skill's behavior (e.g., reading session transcripts and reporting findings with evidence).

Trigger Term Quality

It comprehensively includes natural phrases users would literally say: "it took too long", "why is it so expensive", "what is it doing", "a skill that didn't fire", "ignored plans", "repeated work", plus "bug report for the superpowers maintainers". It covers synonyms and complaint variants exhaustively.

Distinctiveness Conflict Risk

"superpowers session" is a clear niche with distinct triggers (transcript diagnosis, bug reports for superpowers maintainers, session identified by id or path), making conflict with other skills minimal.
