  "works": "`npx -y donsetch@4.10.1` downloaded the linux-x64 Rust binary from GitHub Releases on first use. It ran under a throwaway HOME with no key or account. `mcp` on stdio reports serverInfo donsetch 4.10.1 with 4 tools: web_fetch, web_search, web_crawl and web_screenshot. web_fetch on https://example.com returned clean markdown in 0.08 s with ok:true and content_ok:true. Keyless web_search ('python asyncio gather documentation') returned 5 relevant ranked results in 9.2 s, with the docs.python.org asyncio pages ranked first and labelled official. It flagged honestly that it was degraded: 'failed_engines':5, '3/8 backends available'. web_screenshot of example.com returned a correct 87 KB PNG image block in 7.2 s. web_crawl (max_pages 3, depth 1) on docs.python.org/3/library/asyncio.html fetched 3 sitemap-ranked pages in 1.1 s. It reported stop 'MaxPages' with complete:false and a resume token. On the local JS-only page (with DONSETCH_ALLOW_PRIVATE_EGRESS=1), default web_fetch escalated to the browser and returned the JS-rendered text 'The secret word is pineapple' in 4.9 s. tier '1' marked the page read_status 'thin' ('likely JS-rendered (SPA) \u2026 use tier=auto'). Edge cases return structured errors: a 404 gives code content.notfound with status 404 and a next_action. 'not a url' and an invalid tier give fetch.invalid. A loopback URL is blocked by default with guard.ssrf, and the error names the override variable. `doctor` reports 24 passed, 5 warnings and 0 failed. The warnings are optional paid Bright Data keys, webgl=null, OCR models not cached and two PATH installs.",
  "breaks": "must_contain gives a false negative on JS pages. web_fetch(url, must_contain='pineapple') on the JS-only page, on the default auto tier, returned matched:false with content_ok:true ('NO MATCH \u2026 in 202 chars'), even in a fresh session and on a new URL. It didn't escalate to the browser, though a plain fetch of the same page did. It only matched with tier '2'. An agent using the documented probe would wrongly conclude the text isn't there. Search ran degraded during the test: 5 engines failed and 3 of 8 backends were available. A non-existent host came back as tls.egress ('the egress path is intercepting HTTPS') rather than a DNS error, but this box's sandbox resolves every name to 198.18.0.1 and curl fails the same way, so I don't count it as a donsetch bug. `--version` contacts GitHub ('\u2713 up to date'). The npm README asks for $10\u201349/mo sponsorships (cosmetic). Untested: PDF extraction and OCR (the OCR models weren't downloaded), bot-wall or Cloudflare escalation and 'solve-and-bounce', `login`, BYOK/Bright Data, HTTP transport (`mcp --http`), crawl resume, the actions/focus/section options, and use from a real MCP host.",

The documented must_contain probe returns a confident false 'no match' on a JS-rendered page on the default tier, while web_fetch of the same page renders it correctly.
