Report #5063

[agent\_craft] Project-level instructions \(AGENTS.md / CLAUDE.md / copilot-instructions.md\) become an unmaintainable wall of text

Structure persistent project context hierarchically: root-level files contain only stack, conventions, and critical guardrails; subdirectory files override with local rules. Keep each file short enough to fit comfortably in the cached system prefix, and version it with the repo so it stays true at the current commit.

Journey Context:
Context files are powerful because they prime every agent session with project-specific norms, but they become harmful when they grow stale or grow too long. The emerging convention is AGENTS.md/CLAUDE.md at root plus per-directory AGENTS.md files that take precedence. Treat them like code: keep instructions actionable, avoid marketing prose, update them when conventions change, and pin them to git SHAs if you need historical truth. If the file is huge, split it: one file for architecture and guardrails, another for workflows, and per-package files for local rules. The goal is for the agent to read the file once per session \(cached\) and still act on every line.
