Conciseness

Mostly lean and assumes Claude's intelligence, but rhetorical flourishes like 'That's not pessimism. It's how you build something that doesn't collapse' and 'Not bad luck — bad assumptions' are mild over-explanation that could be trimmed.

Actionability

Provides fully executable guidance for an instruction-only skill: defined confidence/impact rating scales, a vulnerability formula, dependency-chain and reversibility question banks, and a copy-paste-ready output template covering common plan types.

Workflow Clarity

A clear five-step sequence (Extract, Rate, Map, Dependency Chain, Reversibility) is well ordered with the output format as a checkpoint, but explicit validation/feedback-loop checkpoints are absent; acceptable for a non-destructive analytical skill, so it sits at 4 rather than 5.

Progressive Disclosure

Self-contained with no external bundle files and well-organized sections (Core Idea, When to Run, Framework, Output Format, Patterns by Plan Type, Hardest Questions, Deliverable), giving clear navigation with no nested references.

Specificity

Names the domain and several concrete actions ('Surfaces assumptions, dependencies, and execution risks', 'work backwards to find the weaknesses') with only minor granularity gaps, matching the anchor for several specific actions.

Completeness

Explicitly answers both what ('Pre-mortem plan analysis... Surfaces assumptions, dependencies, and execution risks') and when ('Use when before significant resource commitment...') with concrete trigger phrases.

Trigger Term Quality

Includes natural situational triggers ('before significant resource commitment', 'before presenting to a board or investors', 'when feedback has been one-sidedly positive') that users would express, though coverage lacks synonym breadth.

Distinctiveness Conflict Risk

'Pre-mortem plan analysis' is a clear niche with distinct triggers (board/investors, resource commitment, one-sided positive feedback) and minimal overlap with other skills.
