I'm glad you liked it. I was trying to keep both, the title and the content as straightforward as possible.

Another point is, Fable is reasonably cheap if you don't allow it to read or write.

Thank you. Yes I would like to hear more about that - I’d be interested to read details about limiting some of its native tool use.

Fable is good at instruction following, so just adding the snippet I mentioned in the post is good enough for the most cases.

There is a way to control tool invocations at the harness level when writing skills or agents.

Example: ~/.claude/agents/critic.md

    ---
    name: critic
    description: >
      Plan Critic. Reviews an implementation plan. Use before the implementation.
    tools: Read, Agent
    ---

For Claude skills, the frontmatter is different, the keys are:

    allowed-tools: Read Grep
    disallowed-tools: WebSearch Glob
