Coding Agent Cost Controls
A forkable setup for reducing coding-agent cost by shaping environment output, repo maps, model routing, cache stability, and task-level budgets.

Outcome demo
- Reduce cost per completed coding task without relying on every prompt to say 'read less'.
- Wow moment: The agent sees smaller logs, targeted repo context, and stable rules before the expensive model call happens.
- Current bottleneck: Needs repo-specific hooks and enough measurement to avoid hiding useful diagnostics.

Fork with an agent
Use the Markdown route as the build brief and the JSON route for constraints, status, and evidence pointers.
Minimal build
Start with one repo and three controls: trimmed test output, a cheap repo map before full file reads, and stable agent instructions that do not change on each run.
Failure mode
Cost controls can become harmful if they hide compiler warnings, failing tests, or relevant files. Measure completed task cost, not only token count.
