SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

AI-driven missions require an objective, reproducible way to confirm that a worker's output satisfies the defined TaskContract. Manual reviews are error‑prone and cannot enforce consistent gating criteria across many tasks.

Core Features & Use Cases

  • Three‑tiered gate: Precheck validates prerequisites, Mechanical runs eval commands, Contract + Rubric applies detailed acceptance, scope, risk, and scoring checks.
  • Configurable gate profiles: Supports implementation changes, artifact‑only tasks, and closure‑ready cleanup with selective tier execution.
  • Deterministic verdicts: Returns one of pass, fail, block, or error, integrates with retry budgets, escalation policies, and decision records.
  • Use case: In an AI‑agent development pipeline, the evidence‑gate skill automatically validates code changes, documentation updates, or release tasks before they are marked verified.

Quick Start

Invoke the evidence‑gate skill on a specific task to automatically validate its output against the contract and receive a pass, fail, block, or error verdict.

Frequently Asked Questions about evidence-gate

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate verification of AI task outputs against a contract?

Automated verification of AI task outputs validates worker results against a TaskContract using a three-tiered gate, running prechecks, mechanical eval commands, and rubric assessments to return a deterministic pass or fail verdict.

What is tiered verification for AI agent missions?

Tiered verification for AI agent missions is a three-step gating process that validates prerequisites, executes mechanical eval commands, and applies rubric checks to enforce objective acceptance criteria before marking a task complete.

How do I enforce gating rules in an AI development pipeline?

Enforce gating rules in a pipeline by applying tiered verification to worker outputs, which analyzes evidence schemas and returns pass, fail, block, or error verdicts with integrated retry budgets and escalation policies.

Can I run selective verification tiers for artifact-only tasks?

Yes, configurable gate profiles support artifact-only tasks by enabling selective tier execution, allowing you to skip mechanical eval commands and run specific precheck or rubric assessments based on the task type.

What verdicts does an automated task contract evaluation return?

Automated task contract evaluation returns deterministic verdicts of pass, fail, block, or error, integrating with decision records to enforce consistent acceptance criteria across many tasks.

Does tiered task verification work without external dependencies?

Yes, tiered task verification operates as a standalone skill with no external dependencies, executing predefined eval commands and analyzing evidence schemas internally to produce objective gating decisions.
