Tool `buy` name implies a side effect that is not declared
`buy` 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`).

Tool `buy` description mentions money but no `money` side-effect is declared
Description: "Buy a token with another token (swap)." -- 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.
