## MCP tools (2)

### `audit` (~124 tokens)

Audit context tax

Per-turn token cost of the coding-agent instruction files (AGENTS.md, CLAUDE.md, Cursor rules, ...) and MCP servers in a folder, per agent, with advice. Read-only.

Input parameters:

- `models` (array): Models to price (default: claude-sonnet-5.5, gpt-6.1-sol, gemini-3.8-flash).
- `path` (string): Folder to audit (default: the project folder). Its turntax.config.json applies.
- `tools` (array): Agents to report (default: agents with files).

### `fix_preview` (~102 tokens)

Preview safe fixes

Unified diff of the safe fixes turntax --fix would make: duplicate lines, sections that can load only in their folder, large procedures moved into an on-demand skill, misnamed Cursor rules. Every agent keeps reading the moved text. Read-only: nothing is applied.

Input parameters:

- `path` (string): Folder to audit (default: the project folder). Its turntax.config.json applies.
- `tools` (array): Agents whose context must be kept (default: all).
