Buscar na CID-10

cid10_search

Read-onlyIdempotent

Search the Brazilian CID-10 (Classificação Estatística Internacional de Doenças, 10ª Revisão) by Portuguese text.

Use this tool to:

Find CID-10 codes for Brazilian SUS / ANVISA contexts ("infarto", "diabetes", "tuberculose")
Look up the official Portuguese (CBCD/USP) translation of a clinical term
Locate codes for billing, epidemiology, and clinical documentation in Brazil

Returns matches from CID-10 categories (3-char) and/or subcategories (4-char). Search is diacritic-insensitive: typing "infeccoes" matches "infecções". Every word must match (AND), and everyday Portuguese is resolved to the CID-10's own wording (câncer→neoplasia maligna, AVC→acidente vascular cerebral, pressão alta→hipertensão, suicídio→lesão autoprovocada, aids→HIV); when that happens the response says so in vocabulary_notes. This tool searches the Brazilian Portuguese CID-10 V2008 — for the international ICD-11 (current WHO revision, in English by default), use icd11_search.

Input Schema

Name	Required	Description	Default
`level`	No	Restrict search to 3-char categories, 4-char subcategories, or both. Default: all	all
`query`	Yes	Search terms in Portuguese, AND between words (e.g., "diabetes", "infarto", "câncer de mama"); accents ignored, everyday words resolved to CID-10 wording
`max_results`	No	Maximum number of results (1-100). Default: 25

Output Schema

Name	Required	Description
`hits`	Yes	Matching CID-10 V2008 codes with their Portuguese titles, chapter and group.
`level`	Yes	Code level searched: 3-char categories, 4-char subcategories, or all.
`query`	Yes	The search terms as submitted.
`provenance`	Yes	Provenance block: source, URL, data vintage, extraction instant, origin diagnostics, citation, license
`attribution`	Yes	Canonical source URLs of this response (attribution list)
`shown_count`	Yes	Number of codes returned in hits (at most max_results).
`total_count`	Yes	Number of CID-10 codes matching the query, before the max_results cap.
`vocabulary_notes`	No	Present only when a query word was translated to the CID-10's own wording (e.g. "câncer" → "neoplasia maligna"); says which.

TDQS

A4.6/5.0

Behavior5/5

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

Annotations already declare read-only, idempotent, non-destructive, open-world, so the description rightly spends its budget on non-obvious search behavior instead: diacritic insensitivity, AND-across-words semantics, everyday-Portuguese vocabulary resolution with concrete mappings (câncer→neoplasia maligna, AVC→acidente vascular cerebral), the vocabulary_notes signal in the response, and the exact terminology version searched.

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 with purpose, then structured into use cases, behavior, and sibling disambiguation in a logical order. It runs somewhat long and the use-case bullets partially echo the opening sentence, but no sentence is genuinely expendable given the vocabulary-resolution detail.

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?

With an output schema present, the description correctly avoids explaining return shapes while still flagging the one response field an agent must interpret (vocabulary_notes). Query construction, level semantics, version scope, and sibling routing are all covered, leaving nothing an agent needs 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?

Schema description coverage is 100%, so the schema already documents query, level, and max_results including the accent-insensitive and vocabulary-resolution behavior. The description's query guidance largely restates the schema, and level/max_results are only indirectly illuminated by the '3-char categories and/or 4-char subcategories' line, so it meets but does not exceed the baseline.

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 and resource (search the Brazilian CID-10 by Portuguese text) with explicit scope: V2008, Portuguese, categories and subcategories. It explicitly names the sibling it is not (icd11_search) and the boundary between them (international/English ICD-11).

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

Usage Guidelines5/5

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

Provides a dedicated 'Use this tool to' block with three concrete scenarios (SUS/ANVISA coding, official CBCD/USP translation lookup, billing/epidemiology/clinical documentation) and closes with an explicit alternative for the ICD-11 case. Both when-to-use and when-to-use-something-else are covered.

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