Review Assumption

Audits an assumption record and reports findings across four categories: specificity, basis quality, risk assessment, and validation plan adequacy.

Prerequisites

• Apply the shared SDLC conventions in skills/sdlc/references/shared.md.
• .sdlc/knowledge/assumptions/N-<slug>.md, or an assumption document provided in context or as a file path

Steps

1. Read the assumption document.
2. Evaluate it against the checklist below.
3. Report findings by category. Omit categories with no findings.
4. After the review, update status in frontmatter to the appropriate terminal value: Validated (assumption confirmed), Invalidated (assumption disproved — flag affected work), or Deferred (cannot yet be verified).

Review Checklist

Specificity

• Is the assumption statement specific enough to be falsifiable?
• Does it name concrete scope (which users, which load, which environment)?
• Is the status field present and accurate?

Basis Quality

• Is there stated evidence or reasoning supporting the assumption?
• Is the confidence level consistent with the quality of the basis?
• If the basis is weak or absent, is that acknowledged rather than hidden?

Risk Assessment

• Is the impact level (High / Medium / Low) justified by the description?
• Does the risk description name specific components or flows that depend on the assumption?
• Are downstream assumptions or decisions that inherit this risk identified?

Validation Plan

• Is a concrete validation method described (not just "we'll check later")?
• Is there a named owner responsible for validation?
• Is there a deadline or milestone tied to validation?
• If the assumption cannot be validated before implementation, is that risk acknowledged?
