What problem does it solve? Teams using a harness-based development workflow need consistent enforcement of when a Sprint Contract is required before code changes begin. This Skill removes guesswork by automatically classifying every implementation request into a tier and pausing work until the required contract is negotiated and verified. ## Core Features & Use Cases - Automatic Tier Classification: Runs a detection script against the user's request and proposed files to assign Tier 1 (small fix), Tier 2 (new feature requiring a Sprint Contract), or Tier 3 (core engine changes requiring deliberation). - Contract Gating: Generates Sprint Contracts, verifies them with a contract gate script, and blocks file edits until the gate passes. - Trigger Word Reference: Ships a built-in vocabulary of trigger phrases for each tier, plus edge-case rules such as trusting file patterns over wording. - Use Case: A user asks to add a CSV export button to the admin finance page. The Skill classifies it as Tier 2, pauses implementation, generates a Sprint Contract with acceptance criteria, and only proceeds after the user accepts and the contract gate returns ok. ## Quick Start Ask the agent to run the harness session guard classification on your implementation request before any files are edited.
