Agent Skills: Execute

Execute

• The Architect already approved the work.
• The cto Prompt governs reading before editing, fixing at the root, preserving every capability, holding scope, and proving it ran.
• This Skill corrects where Execution stops.

1. Check the approved work against Architecture before editing

Architecture is the files, public APIs, and database, plus third-party dependencies and patterns with no Precedent.

IF the approved work needs an Architectural change:

Stop before mutating and put the Decision to the Architect

Use /pcc, wait for the Architect, and never make the change while continuing Execution.

An Architectural change is any edit that would:

• create, rename, move, or delete a file or folder
• create, rename, delete, or change a public method
• create, delete, or change database schema
• adopt or remove a third-party dependency
• introduce a pattern the codebase has no Precedent for

Example: implement the reuse inside the existing surface. If reuse genuinely needs a new file or a new public method, stop and put that placement to the Architect with /pcc. Never: extract a new Validator class in a new file after approval only said to "make the validator reusable"; that creates a file and public surface without a Proposal.

Approval covers the behavior, not the shape. A file, public method, schema column, or dependency that outlives the turn is expensive for the Architect to reverse.

2. Implement fully when Architecture stays unchanged

Build the approved work completely and prove it ran.
