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.

Quality

Content

71%Weight 40%Scale 1-5

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

A well-structured, actionable procurement pipeline with clear phases, concrete tool schemas, and useful decision guidance. The main weakness is progressive disclosure: a long monolithic file with detailed reference material inlined rather than split into separate files.

Suggestions

Move detailed per-tool input/output schemas and the vendor decision matrix into separate reference files (e.g. tools.md, decision-matrix.md) and link to them from the main body to improve progressive disclosure.

Trim the generic 'LOOK UP, DON'T GUESS' and 'COMPUTE, DON'T DESCRIBE' sections, which are not specific to chemical sourcing and add boilerplate tokens.

Add concrete query examples (e.g. a sample ZINC_search_compounds call with a representative SMILES) and de-hedge the analog-search instructions by stating the assumed tool search mode.

DimensionReasoningScore

Conciseness

Largely lean and table-driven assuming Claude's competence, but includes generic boilerplate ('LOOK UP, DON'T GUESS', 'COMPUTE, DON'T DESCRIBE') and minor restatement of the frontmatter description that could be trimmed.

4 / 5

Actionability

Provides concrete tool names with input/output schemas, numeric thresholds (Tanimoto >= 0.7, purity >= 98%), and a decision matrix, but the analog-search instructions are hedged ('if supported by the tool's search mode') and lack concrete query examples.

4 / 5

Workflow Clarity

A clear six-phase sequence with objectives and soft validation checkpoints (SMILES-match confirmation, mismatch flagging, evidence grading), though checkpoints are advisory rather than explicit validate-fix-retry gating.

4 / 5

Progressive Disclosure

Well-organized with clear headers and tables, but the file is ~260 lines with substantial inline detail (per-tool I/O schemas, decision matrices, interpretation tables) that could be split into reference files, and no external one-level-deep references are signaled.

Description

92%Weight 40%Scale 1-5

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

A strong, specific description that names concrete actions and databases, answers both what and when with natural trigger phrases, and occupies a distinct niche with low conflict risk. Minor synonym coverage is the only gap.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — identity resolution, vendor catalog search across named databases, pricing/availability comparison, and analog identification — covering the full procurement pipeline comprehensively.

5 / 5

Completeness

Explicitly answers both what (find sources, resolve identity, search vendors, compare pricing, find analogs) and when ('Use for chemical procurement, virtual library curation, and where can I buy X questions for synthesis planning') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural user phrasing like 'where can I buy X', 'chemical procurement', 'virtual library curation', and 'synthesis planning', though a few common synonyms (e.g. 'buy chemicals', 'purchase reagents') are absent.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche — commercial chemical sourcing/procurement — with distinct purchasing-oriented triggers and named vendor databases, yielding minimal overlap with adjacent chemistry skills.
