OverviewDiscussionsAdmin

Get one Football Atlas knowledge object

get_entity
Read-onlyIdempotent

Fetch one knowledge object by id, with its claims and the sources each claim cites. Use this once search, answer or get_topic has given you an id. An unknown id is not a dead end: the answer names near-miss ids you can retry with.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesThe knowledge object's id, as returned by search, answer, get_topic or get_related — the last segment of its canonical URL.

Output Schema

  4. First observed

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already convey read-only, idempotent, non-destructive behavior; the description adds value by disclosing the return structure (claims and cited sources) and the near-miss retry behavior for unknown ids. There is no mention of rate limits or auth, but these are less relevant given the annotations.

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?

The description is two sentences with no filler: the first sentence states the function and the second gives actionable retry guidance. It is front-loaded and every clause adds information.

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 one fully-documented parameter, a rich output schema, and annotations covering the safety profile, the description covers the essential usage flow and even handles the error case. Nothing an agent needs to call 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?

Schema coverage is 100%, and the schema's description of the id parameter explicitly states its provenance and the canonical URL segment. The description adds no further parameter-level detail, so the baseline of 3 applies.

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?

The description opens with a specific verb and resource: 'Fetch one knowledge object by id', and specifies what is included (claims and the sources each claim cites). This clearly distinguishes it from sibling tools like get_topic and get_related, which center on different or broader scopes.

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?

It provides explicit sequencing guidance: 'Use this once search, answer or get_topic has given you an id.' This establishes the correct workflow context, though it does not name alternative tools to use for other situations or explicitly state when not to use it.

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