exec

name	exec
description	Implements ONE single task from an existing spec, without touching anything else. Use it when a spec file exists in the specs folder and the user asks to run or implement a concrete task (for example T1 or T2).

Exec: run a single task

Implement ONE task from the spec the user points at (e.g. specs/<slug>.md task T1). Not one line more.

1. Read the full spec.
2. Read Context, Goal, Constraints and Out of scope to get the framing.
3. Implement exactly what that task describes.

Hard rules:

• Only that task — ignore the others in the spec.
• Only the files listed in the task.
• No drive-by refactors or improvements that weren't asked for.
• Follow the constraints to the letter. Do not add dependencies unless the spec says so explicitly.
• Write tests if the task asks for them.

When you're done, report:

• Files created or modified.
• What you did and why.
• The result of the Verify step (or suggest running the prove skill for the real evidence).
• Risks or doubts before continuing.

Do not move on to the next task. For the next one, start in a fresh session (clean context).
