SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Arc verification eliminates ambiguity by requiring fresh proof output to back every completion claim in OpenCode workflows.

Core Features & Use Cases

  • Fresh command verification: Run a chosen proof command and capture full output to validate claims.
  • End-to-end decision making: Reads complete command results to decide if the claim is supported.
  • Guardrails: Prevents premature closings by ensuring evidence matches acceptance criteria.

Quick Start

Verify an arc-tracked claim by selecting the proof command, executing it to produce full output, and evaluating the result.

FAQPage Schema
How do I verify task completion claims in OpenCode workflows?

Verify task completion claims by selecting a proof command, running it to capture full output, and evaluating the results to determine if the claim is supported by fresh evidence. This prevents premature task closings.

What is fresh command verification for arc-tracked tasks?

Fresh command verification requires executing a chosen proof command and capturing its complete output to substantiate acceptance decisions for arc-tracked task claims. It eliminates ambiguity by backing every completion with new evidence.

How do I prevent premature task closings in arc workflows?

Prevent premature arc task closings by using guardrails that ensure fresh proof output matches acceptance criteria before a completion claim is approved. The verification process reads complete command results to decide claim validity.

Can I validate build and test outputs before accepting arc task claims?

Yes, you can validate build and test outputs by selecting the relevant proof command, executing it completely within OpenCode, and evaluating the full output to determine if the verifiable results support the task claim.

Does arc verification work without dependencies or external components?

Yes, arc verification operates without dependencies or external components, relying entirely on selecting a proof command, running it to produce full output, and evaluating the results to substantiate the acceptance decision.

What's the best way to evaluate proof command output for task acceptance?

The best way to evaluate proof command output is to run the selected command completely, capture the full results, and read the entire output to determine if the evidence matches the acceptance criteria for the arc-tracked claim.
