tooluniverse-chemical-sourcing

Find commercial sources for chemical compounds — PubChem/ChEMBL identity resolution then vendor catalog search across ZINC, Enamine, eMolecules, Mcule. Compares pricing, availability, and identifies purchasable analogs when an exact compound is not in stock. Use for chemical procurement, virtual library curation, and 'where can I buy X' questions for synthesis planning.

Content

65%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with concrete tool signatures, thresholds, and decision matrices, and is well-sequenced across phases. It loses points for some generic principle padding, advisory rather than explicit validation loops on batch operations, and absence of file-splitting/external references.

Suggestions

Remove or shrink the generic "LOOK UP, DON'T GUESS" and "COMPUTE, DON'T DESCRIBE" banners, which restate principles Claude already knows; keep only the chemical-sourcing-specific guidance.

Add an explicit validate->fix->retry loop for the parallel vendor search step (e.g., re-query a vendor on structural mismatch or stale stock) rather than only "flag any structural mismatches".

Move the per-tool input/output reference tables into a separate reference file (e.g., references/tools.md) and link to it from SKILL.md to enable one-level-deep progressive disclosure.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with tool signatures and decision matrices that earn their tokens, but generic banners ("LOOK UP, DON'T GUESS", "COMPUTE, DON'T DESCRIBE") restate principles Claude already knows and some sections could be tightened.	2 / 3
Actionability	Provides concrete tool names with input/output schemas, exact property corrections ("ConnectivitySMILES not CanonicalSMILES"), specific ranking criteria, and quantified thresholds (Tanimoto >= 0.7) — copy-paste-ready guidance.	3 / 3
Workflow Clarity	A clear phased 0-5 sequence with a visual flow and red-flag checkpoints is present, but for a batch multi-vendor operation the verification is advisory ("flag any structural mismatches") rather than an explicit validate->fix->retry loop, capping the score per the batch-operations guideline.	2 / 3
Progressive Disclosure	The body is well-organized into sections but is a single monolithic file with no bundle files (references/scripts/assets absent) and no one-level-deep references; detailed tool reference tables that could live in separate files are inline.	2 / 3
	Total	9 / 12 Passed

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concrete, well-triggered, and complete, naming specific databases and concrete actions while explicitly stating when to use it. It is clearly distinguishable from sibling chemistry skills and uses correct third-person voice.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "Find commercial sources", "identity resolution", "vendor catalog search across ZINC, Enamine, eMolecules, Mcule", "Compares pricing, availability", and "identifies purchasable analogs" — each tied to specific named systems, in correct third-person voice.	3 / 3
Completeness	Explicitly answers both what (identity resolution, multi-vendor search, pricing comparison, analog fallback) and when ("Use for chemical procurement, virtual library curation, and 'where can I buy X' questions"), with an explicit "Use for" trigger clause.	3 / 3
Trigger Term Quality	Includes natural user phrasings like "where can I buy X" plus procurement/synthesis-planning terms a user would actually say, giving good coverage of natural trigger language.	3 / 3
Distinctiveness Conflict Risk	Clear niche — chemical compound sourcing against specific named vendor databases — with distinct triggers unlikely to fire for unrelated skills; the body further disambiguates sibling skills.	3 / 3
	Total	12 / 12 Passed
