    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Audit the user's subscriptions. For each: keep, downgrade, redundant, test_replacement, review_unused or keep_critical — with the arithmetic. Savings are split into 'likely' and 'possible' and never double-counted. Costs are what the user actually pays (monthly, all seats).

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Given the outcomes the user needs (free text or capability slugs) and what they already own, recommend per-capability options (owned tools at $0 first) and a minimal stack covering everything, with incremental monthly cost and warnings about skill, collaboration and data sensitivity.

    Why it is in this group

    • The name "compare_solutions" says "compare": a word for reading.
    Description, as the server wrote it
    For one capability (e.g. 'youtube-thumbnails', 'crm-contacts', 'workflow-automation'), compare all known tools: fit, quality scores on the dimensions that matter, required skill, cheapest qualifying plan and limitations.

    Why it is in this group

    • The name "find_alternatives" says "find": a word for reading.
    Description, as the server wrote it
    For a specific product (e.g. Canva), list each capability it provides and the best alternatives — ranking tools the user ALREADY owns first at $0 extra. Pass the capabilities the user actually uses (from get_tool) for a precise answer. Includes the honest case for keeping the tool.

    • The name "find_workflows" says "find": a word for reading.
    Description, as the server wrote it
    Find practical, step-by-step workflows that replace a paid tool or accomplish an outcome with tools the user already owns. Filter by tool being replaced, capability, or free-text query.

    Why it is in this group

    • The name "search_catalog" says "search": a word for reading.
    Description, as the server wrote it
    Natural-language search across software products, capabilities (what software does) and replacement workflows. Understands synonyms, e.g. 'make thumbnails' finds YouTube thumbnail workflows. Returns ranked hits with URLs, plus the tool and capabilities the query most likely refers to.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
