The Cure Protocol

resolve_identifiers

Read-only

RESOLVE UP TO 20 MIXED IDENTIFIERS at once (PMID, DOI, PMCID, NCT, rsID, ChEMBL, ENSG, UniProt, MONDO/EFO, GSE, gene symbol, domain id) into typed records and follow-up links. NEXT: follow the links, e.g. get_gene or get_world_trial.

Input Schema

Name	Required	Description	Default
`id`	Yes	Comma-separated identifiers, up to 20.

Output Schema

Name	Required	Description	Default
`data`	No	The answer. Shape depends on the tool; describe_tool documents it.
`_meta`	No	source, generatedAt, sources (per-source lastSyncedAt and ageHours), rateLimit, disclaimer.

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint, so safety is covered; the description adds the batch cap (20), the fact that output is 'typed records and follow-up links', and the resolution breadth across identifier systems. It does not say what happens when some identifiers fail to resolve or whether partial results are returned — the main remaining gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the core capability and capped identifier list, then a short next-step pointer. No filler and nothing an agent must read past to understand the operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return value detail is unnecessary, and the description covers input types, batch cap, and follow-up routing. Only failure/partial-resolution behavior is unaddressed for what is otherwise a simple single-parameter tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the schema description already says 'Comma-separated identifiers, up to 20', so the baseline is 3. The description still earns credit by enumerating the accepted identifier namespaces, which the schema does not constrain via enum — that is real semantic value for the single input parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (resolve), the resource (mixed identifiers/typed records), and enumerates the identifier families accepted (PMID, DOI, NCT, rsID, ENSG, UniProt, MONDO/EFO, GSE, gene symbol, domain id). It is clearly distinguishable from siblings like get_gene or get_world_trial, which it positions as downstream consumers rather than alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'NEXT: follow the links, e.g. get_gene or get_world_trial' clause gives explicit forward-routing guidance, and 'up to 20 mixed identifiers at once' implies the batch/unknown-type use case. It stops short of stating when NOT to use it (e.g. when the identifier type is already known and a typed getter would suffice).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
