Use before treating a latest-style pointer as a concrete model ID.” [Undominated.ai · upstream description ↗](https://github.com/Lenvanderhof/Undominated.ai/blob/a67bd9b86fca7455ed208403d9ea6f9fe847cd99/skills/undominated-alias-resolution/SKILL.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. ### A good fit for - A latest-style pointer must resolve to one concrete identity before being used as a model ID. ### Weigh up before choosing - Checks one caller-supplied candidate set, refusing unresolved, conflicting and self-targets. It does not verify target existence, candidate completeness, recency or recursively resolve aliases. - Fixture checks establish the documented local behaviour, not performance on an unrestricted set of real tasks. - This resource is not included in undominated-check@0.4.0. Use the pinned source command shown or the complete source download. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - Original definition and MIT licence - Bundled checker source, input contract and synthetic examples ### 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. ### Not established by this review - Model compliance with these instructions on arbitrary tasks - Native integration in every agent host 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.

It may retrieve a newer version than the reviewed source. - Use the pinned command above in the intended project. Replace /absolute/path/to/project with an existing absolute directory when that argument is present. - Download the complete bundle from https://undominated.ai/resources/skills/undominated-alias-resolution/bundle.zip and extract it into a new directory. - Place the extracted directory at .agents/skills/undominated-alias-resolution/ 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.

Use before treating a latest-style pointer as a concrete model ID. license: MIT metadata: author: Undominated.ai version: "1.0.1" --- # Alias resolution Collect the complete candidate set for one alias before resolving it. Never select the first matching row. The caller classifies concrete IDs; this checker does not infer pointer syntax from names. ## Input contract `alias` is required exact non-empty text. `targets` is a required array of objects with exactly `id` (exact non-empty text) and `concrete` (boolean). The IDs are case-sensitive. Identical duplicate records count once. Contradictory `concrete` declarations for the same ID require review. A self-target, any unresolved/non-concrete candidate, zero distinct concrete IDs or multiple distinct concrete IDs requires review. An unresolved candidate is not silently ignored merely because another candidate is concrete. ## Deliverable and limits Return the distinct concrete candidates, unresolved identities, conflicting declarations and reasons for review. Pass means one supplied distinct target is consistently declared concrete with no competing unresolved evidence. It does not prove the target exists, that the alias is current or that the supplied set is complete. No recursive pointer traversal or catalogue fetch is performed. `examples/unresolved.json` requires review despite containing one concrete target. The original conflict example includes a self-target. ## Run the local check Resolve paths relative to this skill directory: ```sh python3 scripts/check.py examples/synthetic.json python3 scripts/check.py /absolute/path/to/your-input.json ``` The examples are **synthetic**, not market measurements. Python 3.10+; standard library only. The script reads one explicit UTF-8 JSON file, prints JSON and makes no network requests or file writes. Exit codes: `0` consistency check passed, `1` review required, `2` invalid input. CLI argument and malformed-input errors return structured JSON; `--help` displays usage text. Unknown or duplicate JSON fields, non-JSON constants and invalid types are rejected. Files are limited to 1 MiB; decimal strings to 1000 characters; identity/field names to 512 characters, with no surrounding whitespace or ASCII control characters. This source-only skill is **not included in undominated-check@0.4.0**. Keep `SKILL.md`, the checker, examples and MIT licence together. A pass validates the bounded supplied-input contract, not production suitability or permission to publish. The skill does not authorize external actions. The download contains SKILL.md . Extract the whole bundle; the supporting files are required. Inspect the included MANIFEST.json for file hashes. By **Undominated.ai**.
