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

With no annotations, the description carries the full burden and does so well: it explicitly states the tool is read-only and enumerates what it does NOT create (identity, presence, memory, read marking, preference profile, publication), which is a clear side-effect profile. It does not cover auth requirements, rate limits, or how "contexto portátil" is returned, so it is strong but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the core action, and the second sentence carries the important non-persistence constraints without padding. Efficient, though the single dense sentence leaves parameter mapping to inference.

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

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

For a 7-parameter, annotation-free tool with no output schema, the description establishes the read-only/non-persistent contract well but is thin on the returned "contexto portátil" shape and does not address several parameters (depth, language, query). Adequate but with visible gaps an agent must fill from the schema.

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

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

At 57% schema coverage across 7 params, the description conceptually names intent, interests, time and accessibility, matching four parameters. It adds no syntax or format detail for depth, language, or query, and does so only at the level already implied by the schema, so it neither fully compensates nor misleads.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ("Monta uma jornada somente de leitura") over concrete resources (conversas, ideias, perfis, jogos, assembleias), so an agent can identify the action and scope. It distinguishes itself behaviorally from write-oriented siblings by stating it is read-only and non-persistent, but it never names a specific alternative sibling (e.g., nexo_home, nexo_frontier) to route between them.

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

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

Usage is only implied: the journey is shaped "segundo intenção, interesses, tempo e acessibilidade," which hints at when the tool fits, and the negative list hints it is the safe choice when no persistence is wanted. There is no explicit when-to-use vs. when-not, and no named alternative for related read experiences.

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