🟢search_catalog(query, kinds, limit)
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.

}🟢get_tool(tool)
Full structured profile of a software product: plans and prices (with evidence status and verification date), capabilities with fit and limitations, honest reasons it's hard to replace, risks, related replacement workflows and sources.

}🟢find_alternatives(tool, capabilities, owned_tools, team_size)
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.

}🟢recommend_stack(query, capabilities, owned_tools, team_size, skill, ...)
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.

}🟢estimate_savings(subscriptions, skill)
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).
