[See setup guidance ↓](#setup)[Original source ↗](https://undominated.ai/resources/skills/undominated-test-time-compute-roi-audit/definition.md) SOURCE REVIEW Reviewed 2026-10-14 Evidence 3 linked sources Publisher Undominated.ai Licence [MIT ↗](https://undominated.ai/resources/skills/undominated-test-time-compute-roi-audit/LICENSE.txt) Revision cb5adc4e6f02 [Read what was—and wasn’t—checked ↓](#review) “Calculates cost-per-accuracy return curves for Best-of-N sampling, search depth scaling, and verifier reranking vs base model upgrading.” [Undominated.ai · upstream description ↗](https://undominated.ai/resources/skills/undominated-test-time-compute-roi-audit/definition.md) Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Pairs a bounded workflow with an offline Python checker and explicitly synthetic example inputs. - Created for recurring evidence and comparison failures: missing facts remain unknown and every conclusion keeps its scope. - It names a concrete failure mode: Determine whether scaling test-time search delivers higher accuracy per dollar than migrating to a larger frontier model. ### A good fit for - Determine whether scaling test-time search delivers higher accuracy per dollar than migrating to a larger frontier model. - Run the local checker against a supplied file for this stated condition: FAILED: BoN accuracy {bon_acc} does not meet frontier baseline {front_acc}. ### Weigh up before choosing - Evaluates candidate generation and verifier pricing. Assumes calibrated reward model ranking. - Fixture checks establish the documented local behaviour, not performance on an unrestricted set of real tasks. - Public GitHub source availability is not yet verified; the complete download contains the reviewed source. - A new npm install path is not yet verified. Use the complete source download. - `2`: Schema error or invalid usage. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - skills/undominated-test-time-compute-roi-audit/SKILL.md - skills/undominated-test-time-compute-roi-audit/scripts/check.py - skills/undominated-test-time-compute-roi-audit/examples/synthetic.json ### Our findings - First-party resource authored by Undominated.ai; this is our own verification record, not an independent endorsement. - The download preserves the complete source and supporting files. Its manifest hashes identify the exact bytes. - The checker names its required fields as: required = ["n_candidates", "base_pass_rate", "bon_pass_rate", "token_cost_per_candidate_usd", "verifier_cost_per_candidate_usd", "frontier_single_pass_cost_usd", "frontier_single_pass_accuracy", "max_allowed_bon_total_cost_usd"]. - The checker rejects the run rather than passing: FAILED: BoN accuracy {bon_acc} does not meet frontier baseline {front_acc}. ### Not established by this review - Model compliance with these instructions on arbitrary tasks - Native integration in every agent host - Public GitHub source identity - Remote installation through the standard Skills CLI - The new npm resource CLI installation The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Add a skill to your workflow. [Upstream setup instructions ↗](https://undominated.ai/resources/skills/undominated-test-time-compute-roi-audit/definition.md) - Download the complete bundle from https://undominated.ai/resources/skills/undominated-test-time-compute-roi-audit/bundle.zip and extract it into a new directory. - Place the extracted directory at .agents/skills/undominated-test-time-compute-roi-audit/ or your host's documented skills directory. Preserve SKILL.md, scripts, examples and licence files together. - Run the documented synthetic example from the skill directory with Python 3.10 or later before using your own evidence. ### Before you start - An Agent Skills compatible host - Python 3.10 or later for the optional checker ### Compatibility Agent Skills compatible hosts · Python 3.10+ ### Implementation Python · Markdown ### Local, explicit inputs - read:user-selected-local-file ### Cost model MIT source at no charge. Your agent host or model provider may charge for use; the included offline checks require no paid API. THE COMPLETE REVIEWED DEFINITION ## Read it before you reuse it.
