   Tool `generate_funnel_chart` description mentions money but no `money` side-effect is declared· generate_funnel_chartexcessive agency

   Description: "Generate a funnel chart to visualize the progressive reduction of data as it passes through stages, such as, the conversion rates of users from visiting a website to completing a purchase." -- 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.

    Tool `generate_sankey_chart` description mentions money but no `money` side-effect is declared· generate_sankey_chartexcessive agency

    Description: "Generate a sankey chart to visualize the flow of data between different stages or categories, such as, the user journey from landing on a page to completing a purchase." -- this references money/payment/refund/etc., but the declared side_effects ([]) don't include `money`.
