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

With no annotations, the description carries the full burden, and it does disclose the meaningful behavior that the payload is forwarded to a human via Telegram - important context for a write/send action. It says nothing about whether the call is fire-and-forget, what confirmation or error the agent gets back (there is no output schema), duplicate handling, or rate limits, leaving real gaps for a side-effecting tool.

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 short sentences with zero filler, and the core action plus destination are front-loaded before the usage condition. Nothing could be removed without losing information.

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 four-parameter submission tool with no annotations and no output schema, the definition covers what it does, where it goes, and when to call it, and the schema fully documents the fields. The remaining gap is what the agent should expect back after the call, which matters somewhat given there is no output 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?

Schema description coverage is 100%, so all four fields are already documented, establishing a baseline of 3. The description adds only that the payload is a 'company inquiry' that lands with a human contact, which slightly frames the intent of the message field but adds no field-level meaning beyond the schema.

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 names a concrete action (passing a company inquiry) and a destination (Rinat's Telegram), so the agent knows this submits an inbound business lead to a human rather than retrieving data like the sibling lookup tools. It stops short of explicitly naming a sibling it differs from, but the resource is distinct enough that confusion is unlikely.

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 sentence 'Use when an agent acts on behalf of a company interested in working together' gives a clear trigger condition tied to the requester's situation. It doesn't spell out when NOT to use it (e.g., non-commercial questions or internal requests), but the trigger is concrete rather than implied.

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