Layered Summary (AGENTS.md)

Generate a layered set of AGENTS.md files so that:

• Deeper directories are more detailed (files + key types/functions + local relationships).
• Higher directories are short rollups of their direct children (architecture map).

This is designed to pair well with Cursor's nested AGENTS.md support: when you work in a folder, you automatically get its local summary plus its ancestors' higher-level context.

Hard constraints

• Create/update only AGENTS.md files. Do not change other files.
• Operate only inside the target root subtree.
• No snippets/excerpts and no long quotes. Summaries must be short and checkable (paths/names).
• Use ASCII only; avoid non-ASCII characters.
• Delegate codebase exploration to Explore subagents (see "Subagent-first workflow"). The main agent remains the only writer of AGENTS.md.
• Don't stop mid-run: continue until the Completion criteria is satisfied. If you are forced to pause, leave a resumable checkpoint (see Resume after interruption) and ensure parent ledgers are accurate.
• Skip generated/vendored/third-party blobs. If present, mention them briefly (and why they exist) but don't document them exhaustively.
• Avoid speculation. Use [unclear] / [TBD] markers when needed.
