# featbench / conan-io__conan-17819 - taskset: [featbench](https://harnessreport.com/tasks/featbench.md) - difficulty: hard - category: feature - language: - runnable from the site: no - agent timeout: 4800s ## Results by harness _none yet_ ## Instruction ``` I want to be warned when I request a specific recipe revision from a local-recipes-index remote that doesn't match the currently available revision in the source. Currently, when I use a local-recipes-index remote and specify a particular revision that differs from what's actually available, the system simply fails with a "recipe not found" error without explaining why. I need a clear warning message that tells me exactly what's happening - that I requested a specific revision but it doesn't match what's available, and that the local-recipes-index cannot provide specific revisions. This warning should appear before the system raises the recipe not found exception, so I understand the reason for the failure rather than just seeing an error. The warning message should include the specific revision I requested in a readable format without timestamp information. This functionality should help me troubleshoot revision mismatch issues more effectively when working with local recipe indexes. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
