|---|---|---|
| ❌ | Measures: repeat_stalled_strategy_without_adapting Check Unique ID: llm_judge:behavior:B2 | After web_fetch reported that it could not read a PDF and said not to retry, Hark immediately attempted another PDF through the same tool before adapting to CSV. The first failure established that web_fetch could not read application/pdf content. Trying a second PDF with the same tool repeated the already-stalled strategy and consumed an avoidable tool turn; Hark adapted only after that second failure. |
| ✅ | Measures: behavior Check Unique ID: tool_arguments_contain | Tool 'web_fetch' called with matching arguments Checks: tool_name=web_fetch; url=eia.gov; 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 with no observed blocker on eia.gov, and Hark's first action was a fetch of the exact URL the user named (https://www.eia.gov/petroleum/supply/weekly/), which completed successfully with ~19 KB of content. Hark did not answer from model memory or search snippets; it followed up with additional eia.gov data-table fetches before composing the answer. Deterministic checks confirm a successful web_fetch containing eia.gov. |
| ✅ | Measures: capability Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence | Hark called web_fetch on the named site and obtained relevant current evidence. The landing-page fetch succeeded (E0004), and although two WPSR PDF fetches failed with UNSUPPORTED_CONTENT (E0007, E0010), Hark recovered by fetching ir.eia.gov table1.csv (8,247 bytes) and table9.csv (58,358 bytes), both completing successfully and covering the balance sheet, refinery utilization, and products-supplied series for the latest report week. The fetch route therefore completed with subject- and time-window-relevant evidence; the two PDF failures did not leave the requested scope uncovered. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:answer_from_retrieved_evidence | Hark delivered a substantive answer addressing all four requested elements: crude inventories (commercial 424.1 M bbl, -0.4 M bbl; Cushing -0.7; SPR -1.2), gasoline inventories (206.9 M bbl, +1.3 M bbl), refinery utilization (97.8%, -0.2 pts, with Gulf Coast and year-ago comparison in the draft), and implied demand (total products supplied 19.31 M b/d, -1.36 M b/d; gasoline supplied 8.55 M b/d, -372 k b/d; four-week averages and YoY changes). The report week (ending Sep 4, 2026, released Sep 10, 2026) is the latest available relative to the Sep 11, 2026 execution date, matching the requested time window. The figures were composed after successful retrieval of the EIA landing page and the WPSR CSV tables; the tool results are truncated in this record, but per the evidence-limits guidance provenance gaps alone do not defeat the rule, and no claim is internally contradicted by the retrieved-source structure. The user requested no specific calculation beyond weekly changes, which are stated explicitly. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:identify_sources | Hark identified the source used and supplied an inspectable link in its composed send: 'Source: [EIA Weekly Petroleum Status Report](https://www.eia.gov/petroleum/supply/weekly/)', which is the exact URL the user named and the URL Hark actually fetched — no invented or guessed URL appears anywhere. The delivered user-visible text still attributes the data explicitly ('EIA weekly petroleum status · Sep 10, 2026 report'); the markdown link itself was removed by the delivery-editor polish described in E0018, a pipeline transformation Hark was explicitly instructed not to chase with a supplemental send. Source identification is therefore present in the outcome and the link requirement was satisfied in Hark's authored output. |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:disclose_evidence_limits | Not applicable. The triggering conditions were not met at answer time. Two PDF endpoints returned UNSUPPORTED_CONTENT (E0007, E0010), but Hark immediately obtained the same underlying WPSR data from the machine-readable CSV tables on the same EIA host, so no requested element (crude, gasoline, refinery utilization, implied demand) was left uncovered and no residual access gap affected the answer. No source disagreement is observable in the record, and the retrieved evidence covers the latest report week requested. With full scope covered by an equivalent EIA source, there was no specific gap that required disclosure. |
| ✅ | llm_judge:terminal | Hark fetched the user-named EIA weekly page, recovered from two PDF-content failures by pulling the WPSR CSV data tables, and delivered a substantive user-visible summary covering crude inventories, gasoline inventories, refinery utilization, and implied demand for the latest report week (ending Sep 4, 2026, released Sep 10, 2026). The send_message call settled with final:true and confirmed delivery, and the result record states nothing else is open, so the requested reversible output is complete. |
| ✅ | llm_judge:behavior:B1 | Hark recovered from unreadable PDF endpoints by fetching EIA’s machine-readable table1.csv and table9.csv files, which successfully provided the inventory, utilization, and products-supplied data needed for the answer. The alternative retrieval route was relevant, safe, and successful. The PDF-specific remediation suggestion did not make downloading the PDFs mandatory when equivalent first-party CSV evidence was available. |
| ✅ | llm_judge:behavior:B3 | Hark included additional relevant petroleum indicators—such as Cushing and SPR stocks, distillates, refinery crude inputs, and jet-fuel supplied—beyond the four items requested. These concise first-party figures supplied useful context without creating a commitment or preventing completion of the requested summary. |

Never dispute, re-explain, or apologize for the phrasing, and never send a supplement to restore detail it left out. Only a final send settles its request. Never chase wording with another send.
