Design exercise: Coding Agent Systems
Repository context, planning, file edits, tools, tests, sandboxes, review loops, and patch delivery. Implement designOutline() returning non-empty values for: repoContext, editLoop, verification. Each value must name a concrete mechanism or decision.
The mechanism
A coding agent is a repository-aware control loop. It needs scoped context, reversible edits, executable verification, and a clear handoff boundary.
Expected evidence
A design outline with repoContext, editLoop, verification plus an explicit failure mode or trade-off.

Hints when you need them
- Name the failure mode before selecting the mechanism.
