Conciseness

Largely lean and assumes competence, with crisp structured sections, tables, and an output template; a few motivational lines ('Founders are optimists by nature', 'Stress testing isn't pessimism. It's calibration.') could be trimmed without losing utility.

Actionability

Provides concrete, specific guidance — a scenario table with defined deltas, named stress questions per assumption type, and a copy-paste-ready output template — with only minor gaps since some 'Test:' steps remain conceptual rather than fully scripted.

Workflow Clarity

Clear five-step sequence (Isolate → Counter-evidence → Downside model → Sensitivity → Hedge) with explicit per-step questions and an output template serving as a checkpoint, though the workflow lacks an explicit validate/retry loop for the destructive-or-batch context it touches.

Progressive Disclosure

Well-organized into clearly signaled sections (methodology, patterns by type, output template) with no bundle files needed; content is appropriately self-contained, though the per-type patterns section is somewhat long and could be split off if the skill grew.

Specificity

Names the domain and several concrete actions ('stress testing', 'betting on a plan whose core assumptions are unvalidated') with concrete example scenarios, but stops short of a comprehensive action list.

Completeness

Clearly states both what ('Business assumption stress testing') and when ('Use before betting on a plan whose core assumptions are unvalidated') with concrete triggers, though the 'when' could be slightly more explicit and broadly phrased.

Trigger Term Quality

Includes natural trigger phrases users would say ('betting on a plan', 'unvalidated assumptions', 'revenue model') plus concrete example assumptions, though it lacks synonyms or file-extension-style variations.

Distinctiveness Conflict Risk

Occupies a clear niche (business assumption stress testing) with distinct triggers and example assumptions, with only minor overlap risk against general planning or analysis skills.
