 The LLM may return verbose JSON like `{"action_id":"logger","payload":{"message":"hello"}}` or compact codebook JSON like `{"v":"1.0.0","c":"<codebook_checksum>","a":"A001","p":{"F001":"hello"}}`. Compact outputs must match `dictionary/model.codebook.json` version and checksum before expansion. The runtime only executes exact `action_id` matches from `dictionary/actions.index.json`; aliases are not executable. Invalid or unknown outputs are rejected without running anything.
 
+Registered suites:
+
+- Math & Conversion: `calculate`, `convert_units`, `generate_uuid`, `random_number`.
+- Text Utilities: `count_words`, `to_slug`, `hash_string`, `truncate_text`.
+- File Operations: `write_note`, `append_to_file`, `read_file`, `delete_file`.
+- Logger: `logger`.
+
+File operations are sandboxed to project-local `notes/`.
+
 Codex environment: `.codex/environments/environment.toml` defines setup plus Build, Test, Generate Dictionary, Precommit Check, Run Logger, Query Logger, and Serve Llama actions.
 
 CI and hooks: `.gitea/workflows/ci.yml`, `.woodpecker.yml`, and `.githooks/pre-commit` all use `scripts/precommit-check.sh` to verify formatting, tests, and dictionary generation.
