2 findings on this tool

  1. highexcessive agencyf-r3-pay

    Tool `pay` name implies a side effect that is not declared

    `pay` looks like a side-effecting tool (its name contains a mutation verb), but its `side_effects` declaration is []. A policy synthesizer cannot produce safe rules for this tool because it cannot tell what it actually does.

    fix: Declare the tool's true side effects explicitly. If the tool is genuinely read-only, rename it to match (e.g. `email.preview` rather than `email.send`).

  2. mediumexcessive agencyf-r5-pay

    Tool `pay` description mentions money but no `money` side-effect is declared

    Description: "Pay for API access using tokens." -- this references money/payment/refund/etc., but the declared side_effects ([]) don't include `money`. A capframe-bind policy that relies on declared side_effects to scope spend caveats will under-scope this tool.

    fix: Add `money` to the tool's `side_effects` declaration, or rewrite the description to clarify that no actual money moves.
