TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered and the bar is lower. The description adds a content preview of the response, but that largely duplicates what the output schema already carries. Nothing is said about behavior on unknown/ambiguous slugs or how large timelines are paginated.

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?

The response contents are front-loaded, then input format, then examples – a sensible order with no filler. The Portuguese/English duplication and repeated example list add length, though the bilingual mirroring is a deliberate convention rather than noise.

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?

For a one-parameter read tool with an output schema and full annotation coverage, the description is close to complete: it says what comes back, what input it accepts, and what questions it answers. The one gap is that it never tells the agent where to obtain a slug (listar_temas) when the caller only has a free-text name.

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 single parameter is already documented as 'Slug ou URL do tema'. The description reinforces this with the concrete URL path form /tema/<slug>, which is mild added value, but otherwise the schema does the work and the baseline of 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+resource with concrete content: a full developing case returning a dated timeline with N sources per step, open questions, latest update, people/companies, countries and covering outlets. An agent can tell this is the 'full case dossier' read. It does not explicitly differentiate itself from the sibling get_historia, which reads as a related single-story lookup, 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 Guidelines4/5

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

The example phrasings («Linha do tempo do caso Mercado Bitcoin», «O que ainda está em aberto nesse caso?») give clear situational context for when this tool is the right choice. There are no explicit exclusions or pointers to siblings such as listar_temas for discovering a slug, so it is clear-but-not-routing guidance.

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