Extraire les tableaux

extract_document_tables
Read-onlyIdempotent

Extracts tables from a document, returning each table's rows, cells, and page location. Use it to analyze structured content without manual copying.

Instructions

Renvoie les tableaux d'un document (lignes et cellules), avec leur page.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

    "arguments": {
      "document_id": "<document_id>"
    },
    "name": "extract_document_tables"
  }
}

B3.2/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so safety and repeatability are covered. The description adds that the result is structured per table with rows, cells and page attribution, which is genuine context beyond the annotations, but it says nothing about behavior when a document has no tables or how large documents are handled.

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?

A single front-loaded sentence with zero filler; the resource and return shape come first. Its brevity is efficient, though it leaves so much unsaid that it borders on under-specification.

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

Completeness3/5

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

With an output schema present and full parameter coverage, the description need not explain return values or argument formats, and annotations carry the safety profile. What is missing is routing guidance versus sibling extractors and any note on empty-result behavior for a document with no tables.

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 coverage is 100% and the schema itself documents both document_id (pointing to list_documents) and max_tables with its bounds and default. The description adds no further meaning to either parameter, 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?

The description gives a specific verb and resource (returns the tables of a document) and adds the shape of the result (rows and cells, with page numbers), which separates it from generic content/image extraction siblings. It does not explicitly name an alternative such as extract_document_content, so it stops short of a 5.

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

Usage Guidelines2/5

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

There is no statement of when to use this tool rather than extract_document_content or extract_document_images, and no prerequisites or exclusions. Usage must be inferred entirely from the purpose sentence.

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