Goal Verifier

When to Use

User says verify goal or task matches this capability
User says confirm success or task matches this capability
User says did I achieve this or task matches this capability
User says check if done or task matches this capability

Workflow

Restate the original goal in one sentence.
List acceptance criteria (explicit or inferred from conversation).
Check each criterion: pass / fail / partial with evidence.
If any fail, invoke self-refine-loop or report gaps.
Only mark complete when all critical criteria pass.

Integrations

self-refine-loop
auto-tester

Error Handling

Failure	Response
Goal undefined	Ask user to confirm goal before verifying.
False positive risk	Require evidence (file path, command output, or test result).

Gotchas

Verification is read-only; do not mutate artifacts during checks.

Example

Input: User request matching triggers above. Output: Structured result per workflow with integrations invoked as needed.
