SDD Scenario Writer

Help the user author or improve an evaluation scenarios document that will be consumed by the sdd-evaluator agent inside the SDD Triad loop. Well-designed scenarios produce specific, actionable feedback. Vague scenarios produce feedback the writer cannot act on.

Prerequisites

  • The user should have (or be working on) a companion spec document. The scenarios are the evaluation complement to the spec.
  • No MCP tools required — this is a pure authoring skill.

What scenarios are for

The scenarios file is the evaluator's primary input. The evaluator reads the scenarios and a proposal, then tests the proposal against every scenario. The evaluator's feedback goes back to the writer (after sanitization by the orchestrator) to guide revisions.

The writer never sees the scenarios. This is the information barrier — the defining feature of the SDD Triad. Scenarios must be written so that an evaluator can produce specific, actionable feedback to the writer without naming any scenario.
