Codegen integration

Codegen support is beta.

tokenjuice install codegen inserts a marker-delimited instruction block into the current git/project root AGENTS.md. Codegen documents automatic repository rule-file detection and lists AGENTS.md as the preferred default rule file, so tokenjuice uses that shared project instruction surface instead of inventing a hook contract.

tokenjuice install codegen
tokenjuice doctor codegen
tokenjuice uninstall codegen

By default, tokenjuice resolves the nearest git root before writing AGENTS.md. Set CODEGEN_PROJECT_DIR=/path/to/workspace to override the target workspace explicitly.

The installed block tells Codegen agents to use tokenjuice wrap -- <command> for terminal commands likely to produce long output, and to use tokenjuice wrap --raw -- <command> only when raw bytes are required.

Existing AGENTS.md content is backed up before install and preserved outside the managed tokenjuice block. Uninstall removes only the tokenjuice block.

doctor codegen reports ok when the AGENTS.md block exists, includes tokenjuice wrap guidance, includes the raw escape hatch, and does not suggest the full-output escape hatch.

This integration is guidance-only. Codegen rule files are prompts that guide agent behavior; they do not intercept or replace terminal command output.
