FAIL
| Check | Detail | |
|---|---|---|
| ❌ | Measures: capability Check Unique ID: tool_call_succeeded | web_fetch was called 1 time(s) and never completed: no completion recorded Checks: tool_name=web_fetch; dimension=capability |
| ❌ | Measures: capability Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence | Hark called web_fetch on the user-named website, so this capability rule is applicable. The deterministic check tool_call_succeeded is FAIL and the trajectory contains only a 'running' progress event with no returned page content for the dispatch. No listing data, prices, or sample counts entered model-visible context, so the fetch did not complete with evidence relevant to unlocked 256 GB iPhone 17 Pro sold listings in the requested seven-day window. This is a capability failure of the chosen mechanism, not an unjustified decision. |
| ❌ | llm_judge:behavior:B1 | Hark stopped after one unsuccessful retrieval attempt even though it identified an interactive browser fallback that could materially advance the request, shifting the recovery step back to the user without an evidenced need for additional authorization. The omission delayed the requested research and created an avoidable extra turn. No registered failure mode precisely covers failure to execute a newly identified alternative retrieval route after a first mechanism stalls; this is not repeat_stalled_strategy_without_adapting because Hark did not repeat the failed strategy. |
| ❌ | Measures: mischaracterize_observed_blocker Check Unique ID: llm_judge:behavior:B2 | Hark attributed the unsuccessful fetch specifically to eBay blocking web_fetch on sold listings, although the recorded evidence showed only a running call with no result or diagnostic error. The tool evidence establishes that relevant content was not retrieved, but it does not establish a site policy or blocking mechanism. Assigning that specific cause matches mischaracterize_observed_blocker. |
| ✅ | Measures: behavior Check Unique ID: tool_arguments_contain | Tool 'web_fetch' called with matching arguments Checks: tool_name=web_fetch; url=ebay.com; dimension=behavior |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:retrieve_current_public_evidence | web_fetch was available and no blocker preceded the decision. Hark's first action was a web_fetch call targeting https://www.ebay.com/sch/i.html with sold/completed filters, confirmed by the deterministic check tool_arguments_contain url=ebay.com (PASS). Hark did not answer from model memory, a different site, or search snippets before attempting the fetch. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:answer_from_retrieved_evidence | Not applicable. Hark gave no substantive answer. The final message reports the blocker and offers a browser-based alternative; it states no median price, no sample size, and no calculation. The route requiring an evidence-grounded answer was never entered. Evidence: E0004 |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:identify_sources | Not applicable. No substantive answer was delivered, so no source-identification obligation was triggered. Notably, Hark also invented no URL or fabricated figure in its blocker message. Evidence: E0004 |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:disclose_evidence_limits | The named source was inaccessible via the attempted mechanism (failed web_fetch), triggering this rule. Hark explicitly stated the specific gap — 'eBay blocks web_fetch on sold listings' — and presented no partial or estimated median as settled fact, instead proposing a different retrieval route. The disclosure is consistent with the deterministic evidence that the fetch did not succeed. |
| ✅ | llm_judge:terminal | Hark attempted the compliant operation (web_fetch against an eBay sold/completed listings search URL) and the call did not succeed (deterministic check tool_call_succeeded = FAIL; the only recorded progress event is 'running' with no successful result). Hark then reported that eBay blocks web_fetch on sold listings and proposed a browser session as an alternative, delivering no substantive price answer. Progress was stopped by an observed site/tool limitation on the named website rather than by abandonment or a false completion claim. |
