get_updates

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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose that the response surfaces chat ids, which is the key behavioral payoff, but it says nothing about whether fetching updates consumes or acknowledges them (a real concern for bot update endpoints), about ordering, or about any rate limits. For a tool with zero annotation coverage, that leaves meaningful gaps.

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?

It is a single compact sentence with the core purpose front-loaded and the useful context tucked into a parenthetical. Nothing is wasted, though the extreme brevity contributes to the parameter gap.

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?

Because an output schema exists, return values need not be described, and the description correctly focuses on purpose. Still, for a tool that is the entry point of a setup workflow, it should say how it relates to add_chat and explain the one parameter it exposes.

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?

There is one parameter, 'limit', with 0% schema description coverage, so the description is the only place its meaning could be explained. The description never mentions it, leaving the agent to guess what the default of 10 means and what the upper bound is.

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 states a specific verb and resource: 'List recent messages sent to the bot.' That is clearly distinct from the send_* siblings, which push content out rather than read it in. It doesn't explicitly name a sibling for contrast, but the read/write split is obvious enough from the verbs.

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?

The parenthetical 'helps first-time setup' implies the intended moment to call it, namely discovering chat ids before add_chat or list_access. However, it never states that linkage outright or says when not to call it, so the agent has to infer the workflow from context.

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