TDQS

A4.8/5.0

Behavior5/5

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

Annotations cover safety (readOnly, idempotent, non-destructive, openWorld), and the description adds substantial context beyond them: missing fields return null, videoUrl is a YouTube embed or null, pauta is capped at 15 items, id inexistente returns an error, and status carries an enum of agendado/encerrado/cancelado. These are exactly the behavioral traits an agent needs and that annotations cannot express.

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 the core purpose and the routing constraint, then the return shape, then prerequisites/alternatives — good ordering and no filler. It is slightly over-packed: the long field enumeration partially duplicates the existing output schema, which costs a little efficiency.

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-param read tool with annotations, full schema coverage and an output schema, the description supplies everything extra an agent needs: field semantics, null/error behavior, the pauta cap, status enum values, and the sibling routing rule. Nothing material is missing.

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

Parameters4/5

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

Schema coverage is 100% and the single parameter is fully documented in the schema, so the baseline is 3. The description adds genuine semantic value by telling the agent the id must be sourced from senado_ecidadania_listar_eventos, linking the parameter to its origin rather than restating its type.

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?

Names a specific verb (obter detalhe completo) and resource (evento interativo do e-Cidadania), and immediately enumerates the three event subtypes (audiência, sabatina, live). It explicitly contrasts itself with senado_ecidadania_listar_eventos, so an agent can route correctly without opening either schema.

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?

Gives both a prerequisite ('Obtenha o `id` antes via senado_ecidadania_listar_eventos') and an exclusion ('Para apenas listar/rankear eventos ... use senado_ecidadania_listar_eventos, não esta'). This is explicit when-to-use and when-not-to-use guidance naming the alternative.

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