4 findings on this tool

1. highexcessive agencyf-r3-buy

   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`).

2. highexcessive agencyf-r4-buy

   Tool `buy` accepts an unbounded monetary / quota value

   The numeric parameter(s) `quantity` have a money/quota-shaped name but no `maximum` constraint. An LLM tricked by indirect-injection can call the tool with arbitrarily large values.

   fix: Add a `maximum` (and ideally `minimum`) to each money/quota numeric, OR enforce the cap via a capframe-bind `--limit` caveat at the agent boundary.

3. mediumunconstrained inputf-r1-buy

   Tool `buy` accepts unconstrained string input

   The following string parameter(s) have no `maxLength` constraint: `deliver_to`, `item_id`, `session_id`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.

4. mediumexcessive agencyf-r5-buy

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

   Description: "Buy items at market price from the station exchange (No fees for instant fills. Items delivered to cargo (or storage if cargo full). Use deliver_to=storage to send directly to storage. Use auto_list=true to automatically place a buy order for any unfilled quantity (1% listing fee applies). Accepts item_id or item name (e.g. 'Iron Ore').)" -- 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.
