get_channel_info

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it says almost nothing. It does not state whether the call is read-only (implied but unstated), what happens for an invalid or unreachable channel, whether auth/bot membership is required, or how private chats behave. For a lookup tool interacting with external accounts, this is a meaningful gap.

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?

A single efficient sentence with the verb and resource front-loaded and no filler. It is appropriately short, though it is arguably too thin rather than too long.

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?

With no output schema and no annotations, the description must explain what 'information' is returned (title, description, member count, pinned message, etc.) and any behavioral caveats. It provides neither, so an agent cannot anticipate the response shape or error conditions.

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% and the single 'channel' parameter already enumerates accepted formats (@username, phone number, chat ID) in the schema. The description adds nothing beyond identifying the entity type, so the baseline 3 applies.

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?

States a specific verb ('Get') and resource ('information about a Telegram channel, group, or private chat'), and the entity types accepted are clear. However, it does nothing to separate itself from siblings like get_available_channels or get_chat_status, which an agent must disambiguate on its own.

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?

There is no when-to-use guidance, no exclusions, and no mention of alternatives among the seven sibling tools. The agent is left to infer that this retrieves metadata for a channel it can already identify, versus listing channels or checking status.

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