Tool `view_market` accepts unconstrained string input
The following string parameter(s) have no `maxLength` constraint: `category`, `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.

Tool `view_market` description mentions money but no `money` side-effect is declared
Description: "View the market at the current station (Without item_id: returns a compact summary (best prices, quantities) for all items — use category to filter (e.g. 'ore', 'commodity', 'module'). With item_id: returns full order book depth for that item. Accepts item_id or item name (e.g. 'Iron Ore'). Every response includes current_tick. Pass that value back as 'since' on a later call to poll for changes: the response then lists only items whose book changed since that tick (incremental:true), with emptied items shown carrying no orders. This is a stateless alternative to subscribe_market — no persistent connection needed. Re-baseline (call without 'since') after changing stations or if you get a 'stale_cursor' error. Fuel and contraband are excluded from incremental diffs. Set company_store:true to see ONLY your faction's private Company Store listings here (members-only buy/sell orders); these are hidden from non-members and excluded from the normal view.)" -- 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.
