Consultar Código CID-10

cid10_lookup

Read-onlyIdempotent

Resolve CID-10 codes to their Brazilian Portuguese descriptions, confirm categories or subcategories, and retrieve gender or cause-of-death restriction flags.

Instructions

Look up a specific CID-10 code and return its Portuguese name.

Use this tool to:

Resolve a code to its Brazilian description ("I21" → "Infarto agudo do miocárdio")
Confirm a 3-char category or 4-char subcategory exists in CID-10
Retrieve gender / cause-of-death restriction flags when applicable

Accepts both dotted ("A00.1") and undotted ("A001") forms; returns the canonical display.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`code`	Yes	CID-10 code (e.g., "A00", "A00.1", "A001", "I21"). Dotted and undotted forms both accepted.

Output Schema

TableJSON Schema

Name	Required	Description
`hit`	Yes
`code`	Yes
`found`	Yes
`provenance`	Yes	Provenance block (contract v1.1): source, URL, data vintage, extraction instant, origin diagnostics, citation, license
`attribution`	Yes	Canonical source URLs of this response (attribution list)

TDQS

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety is covered. The description adds genuine behavioral context beyond that: both dotted and undotted inputs are accepted, the canonical display form is returned, and gender/cause-of-death flags may be present. Output formatting is partly covered by the output schema, which caps this at a 4.

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

Conciseness4/5

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

Front-loaded one-line purpose followed by a tight bulleted breakdown and a closing note on input formats. Some content (dotted vs undotted forms) repeats the schema description, which is minor redundancy but not bloat.

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

Completeness5/5

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

For a single-parameter, read-only lookup with an output schema and full annotation coverage, the description supplies everything needed: what it returns, accepted input forms, and use cases. Nothing an agent needs to invoke it correctly is missing.

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

Parameters3/5

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

With a single parameter at 100% schema description coverage, the schema already documents the code field, its pattern, and its dotted/undotted acceptance. The description largely restates that same dotted/undotted flexibility, adding little new parameter-level meaning, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb and resource ('Look up a specific CID-10 code') and scopes it to an exact-code resolution with an example ('I21' → 'Infarto agudo do miocárdio'), which implicitly separates it from the search-oriented sibling cid10_search. It never names that sibling explicitly, so differentiation must be inferred.

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 'Use this tool to:' block gives three concrete triggering scenarios (resolve a code, confirm a category/subcategory exists, retrieve restriction flags), which is clear positive guidance. It stops short of stating when NOT to use it or naming cid10_search / cid10_chapter as the alternative for fuzzy or hierarchical lookups.

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