Checks

CheckDetail
✅Measures: behavior
Check Unique ID: tool_arguments_contain
Tool 'web_fetch' called with matching arguments
Checks: tool_name=web_fetch; url=crates.io; dimension=behavior
✅Measures: capability
Check Unique ID: tool_call_succeeded
web_fetch completed on call 1
Checks: tool_name=web_fetch; dimension=capability
✅Measures: behavior
Check Unique ID: llm_judge:rule:retrieve_current_public_evidence
web_fetch was available and Hark called it against the user-named site crates.io (its v1 crates API endpoint) before answering, with no observed blocker. The deterministic checks confirm the call targeted crates.io and succeeded.
Evidence: E0002, E0004
✅Measures: capability
Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence
The fetch returned status 200 with JSON listing ten crates sorted by recent_downloads, including names, descriptions, default/max stable versions, and recent download counts, with updated_at timestamps as recent as 2026-09-10, consistent with the 2026-09-11 execution date. The evidence is directly relevant to the requested subject and a current time window.
Evidence: E0004
✅Measures: outcome
Check Unique ID: llm_judge:rule:answer_from_retrieved_evidence
Every crate name, version, and recent-download figure in the delivered answer matches the fetched JSON exactly (hashbrown 0.17.1 / 647,764,583; syn 3.0.5 / 561,323,557; getrandom 0.4.3 / 556,375,586; rand 0.10.2 / 426,778,741; rand_core 0.10.1 / 420,523,982; bitflags 2.13.2 / 417,191,592; windows-sys 0.61.2 / 404,004,947; quote 1.0.47 / 362,631,199; libc 0.2.189 / 358,071,073; thiserror 2.0.20 / 357,519,479). Ranking order matches the API's sort order. Crate summaries are consistent with the returned descriptions. Version selection uses the crates' default/max stable version, a defensible and evidence-backed choice (libc's alpha 1.0.0-alpha.4 was excluded in favor of the stable default). The requested method (the site's recent-downloads sort) is explained as a 90-day window.
Evidence: E0004, E0005, E0006, E0007
✅Measures: outcome
Check Unique ID: llm_judge:rule:identify_sources
The answer names crates.io as the source and links back to the user's own crates.io sort URL, plus per-crate crates.io pages whose paths are derivable from the crate `id` values returned by the fetch (the result also returned /api/v1/crates/<id>/... link paths). No URL was fabricated for a resource not evidenced in the retrieval.
Evidence: E0004, E0005, E0007
✅Measures: behavior
Check Unique ID: llm_judge:rule:disclose_evidence_limits
The user asked for downloads 'today', while the retrieved evidence reports crates.io's recent_downloads aggregate. Hark disclosed the mismatch by explicitly defining the window in the delivered message ('"recent" = last 90 days') and again in the follow-on message ('by recent activity (last 90 days)'), so the partial coverage of the requested time window was stated rather than presented as same-day data.
Evidence: E0004, E0005, E0006
✅llm_judge:terminalHark fetched crates.io, obtained the ranked crate list, and delivered a final message (final: true) with all ten crates, versions, recent download counts, and summaries. No blocker, no pending user input, and no irreversible action remained.
Evidence: E0004, E0005, E0007
✅llm_judge:behavior:B1Rendered one coherent answer across three consecutive user-facing messages rather than as a single message. The messages form a readable introduction, result table, and conclusion. The 90-day qualifier appears immediately before the table, and the evidence shows only one final send_message call, so there is no supported harmful duplication or agent-selected fragmentation failure.
Evidence: E0005, E0006, E0007, E0008
