Stage 3 — Execute

Autonomous implementation, one component at a time.

The execution loop runs your AI coding tool in a cycle: pick the next incomplete component, implement it, verify, commit, and exit with fresh context.

The problem

✕
Context windows fill up and output quality degrades mid-task
✕
Agents lose track of cross-cutting decisions across long sessions
✕
No structured memory means the same mistakes repeat across iterations
✕
Manual orchestration of agent work does not scale beyond simple tasks
✕
Not everyone knows what an execution loop is or how to use or build it

What ContextRail enables

1
1

Fresh context window per component—no accumulated hallucinations

2
2

File-based progress tracking persists state across iterations without LLM memory

3

Cross-cutting decisions documented in decisions.md carry forward automatically

4
4

Gate failures documented with root cause and retry strategy for the next run

5
5

Standard checked through every iteration of the execution loop
