2 findings on this tool

  1. mediumunconstrained inputf-r1-load_passenger

    Tool `load_passenger` accepts unconstrained string input

    The following string parameter(s) have no `maxLength` constraint: `destination`, `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.

  2. mediumexcessive agencyf-r5-load_passenger

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

    Description: "Load all waiting passengers bound for a destination into your passenger berths (You must be docked and have passenger berths (built into liner-class ships, or from an installed passenger cabin module). Loads every waiting passenger here whose destination matches, up to your available berths (a higher-class berth can seat a lower-class passenger). Run it again for other destinations to fill berths for multiple stops. Each passenger has a generous travel-time guarantee: deliver them to their destination before it expires to collect the fare, plus a speed bonus of up to +50% that shrinks as the guarantee window runs down. Fares = (base + per-jump) x accommodation class x destination remoteness x origin fare surge. Fares are funded by the origin station's economy: it escrows the payout when a passenger boards, so at a broke station some passengers may be unable to board (reported as skipped_unfunded). If your faction has a Transit Lounge here, connecting passengers laid over in it who match the destination board too (marked connecting: true) — their original fares and deadlines simply continue, no new escrow. Call multiple times before undocking to build a route.)" -- 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.
