Retrieves the Jinni usage documentation (content of README.md).

Reads context from a specified project root directory (absolute path). Focuses on the specified target files/directories within that root. Returns a static view of files with paths relative to the project root. Assume the user wants to read in context for the whole project unless otherwise specified - do not ask the user for clarification if just asked to read context. If the user just says 'jinni', interpret that as read_context. If the user asks to list context, use the list_only argument. Both targets and rules accept a JSON array of strings. The project_root, targets, and rules arguments are mandatory. You can ignore the other arguments by default. IMPORTANT NOTE ON RULES: Ensure you understand the rule syntax (details available via the usage tool) before providing specific rules. Using rules=[] is recommended if unsure, as this uses sensible defaults.

Guidance for AI Model Usage

When requesting context using this tool:

• Default Behavior: If you provide an empty rules list ([]), Jinni uses sensible default exclusions (like .git, node_modules, __pycache__, common binary types) combined with any project-specific .contextfiles. This usually provides the "canonical context" - files developers typically track in version control. Assume this is what the users wants if they just ask to read context.

• Targeting Specific Files: If you have a list of specific files you need (e.g., ["src/main.py", "README.md"]), provide them in the targets list. This is efficient and precise, quicker than reading one by one.
