Report #92665

[agent\_craft] Agent has no persistent understanding of project conventions, architecture, or constraints at session start

Maintain a project-level instruction file \(e.g., CLAUDE.md, .cursorrules, AGENT.md\) in the repository root. Include: project architecture overview, coding conventions, build and test commands, common pitfalls, and any hard constraints. The agent reads this at the start of every session, providing instant project context without consuming exploration tool calls.

Journey Context:
Every new agent session starts with zero project knowledge. The agent must spend multiple tool calls discovering the project structure, conventions, and constraints—wasting context budget and time on information that is stable across sessions. A project instruction file acts as cold-start context that is always available. The key insight is that this file should capture the unwritten rules: 'always use pytest', 'the auth module is legacy—do not modify', 'API responses follow this schema'. These are exactly the things that are hard to discover from code alone and easy to get wrong. The file should be curated by the developer, not auto-generated, because it needs to encode judgment and conventions, not just structure. The tradeoff is that the file must be maintained as the project evolves, but a slightly stale instruction file is still far better than no instructions at all. The file also serves as a communication channel between developer and agent, making agent behavior more predictable and controllable.
