Slice Guard

Stay in control of AI code edits

Does your AI agent try to refactor the entire universe when you only asked for a simple bug fix? slice-guard is a professional-grade safety layer for AI coding agents that enforces incremental, verifiable delivery. It transforms risky, large-scale code changes into a series of small, manageable "slices" that are buildable, testable, and easy to roll back.

What it does

Instead of one giant file dump, this skill forces the agent to follow a strict protocol:

• Scope Locking: Explicitly defines what is in-scope and forbids "drive-by" cleanups or unrelated refactors.
• Slice Planning: Breaks tasks into the smallest possible testable increments (typically 1-3 files).
• Verification Gates: Mandates build and test runs for every slice before moving to the next.
• Safety-First Architecture: Includes automated rollback notes and hard stops for high-risk operations like schema changes or external API breaks.

Why use this skill?

Standard prompts often lead to "AI drift" where agents touch unrelated files or break the build late in a task. slice-guard acts as a guardrail, ensuring that if a change fails, you only lose a tiny slice of work rather than a sprawling multi-file mess. It includes embedded writing quality controls and audit trails without needing additional planning or review skills.
