Draft, stacked on #536. Review only the last commit (e1f3017); the first two are #536.

Rewrites the firecrawl_find_tools description to lead with the lookup sequence and the field rule:

Find Alexandria data providers and read their contracts; free, and executes nothing. {"urls": [""]} lists tools covering a site, {"query": ""} searches, no arguments browses categories. Each listed tool has separate provider and capability fields: read its contract with {"providers": [provider], "capabilities": [capability]} (never the combined id), then run it with firecrawl_scrape {"alexandria": {provider, capability, options}}. Alexandria covers companies, people, jobs, filings, public records, real estate, places, prices, package registries, news, research and more. Prefer normal firecrawl_search for a data task; it already returns matching providers with web results. Use this tool for a full contract, catalogue browsing, or before scraping the same fields from several pages.

992 → 821 characters. It also defines the description once in alexandria.ts; server.ts and the search surface had identical copies.

Evidence

Same setup as #536: description-only overrides, replayed Firecrawl responses, 19 tasks. First contract lookup right, current text → this text with #536. These runs used #536's earlier wording, which also said "not its provider-prefixed id"; #536 has since dropped that clause after it checked out the same on Luna and Sol.

The models routed through OpenRouter ran 1–2 repeats. Claude Sonnet 5.5 and Kimi K3 rarely looked up a contract (they ran the provider directly), so they are left out. Judged accuracy on Luna and Sol: 0.99 → 0.99 (Luna), 0.99 → 0.97 (Sol, replay) and 0.96 → 0.99 (Sol, live); the Sol dips are a model declining to quote a transcript. The other models weren't judged.

What this adds over #536 alone: on Sol, 0.37 fewer tool calls per run in replay and 0.32 live, against 0.21 for the parameter text alone. On Luna, the parameter text alone did as well or slightly better (0.25 vs 0.16).

Why a draft

• tests/mcp-description-budget.test.mjs pins "Prefer normal firecrawl_search" as routing copy from your AX runs. The tested text ended "firecrawl_search already returns matching providers with web results; use this tool for …". This PR keeps your sentence instead, so this exact wording wasn't run.
• Dropped from the current text: "nextTool identifies further discovery or pagination", "Use firecrawl_search when you also need web results", and the long category list (now shortened). Pagination, category browsing and search → find_tools routing weren't covered by these tasks.
• Glad to cut this down to one added sentence on the field rule, or to close it if fix(find-tools): say capabilities take the address, not the id #536 is enough.

pnpm test: 166/166 pass, with regenerated contract snapshots.
