create_channel

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

The description adds behavioral context beyond the annotations by explaining that broadcast channels allow only admins to write and that megagroup=True creates a supergroup. However, it fails to disclose the behavior when both flags are set or when neither is set, and it does not mention potential side effects or permissions needed. The annotations provide the safety profile, but the description leaves edge cases ambiguous.

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?

The description is short and covers the key flag distinctions in a compact format. The Args block is structured, but the language could be more formal and the layout slightly clearer. Overall, it earns its place without excessive verbosity.

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?

Given the tool's moderate complexity and the existence of an output schema, the description is minimally sufficient. It explains the two core flags but lacks guidance on parameter defaults, mutual exclusivity, and the practical difference from create_group. The description does not fully equip an agent to handle conflicting flag values or understand the exact behavior of the operation.

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?

With 0% schema description coverage, the description is responsible for explaining parameters. It does explain broadcast and megagroup semantics well, but it does not elaborate on the 'title' or 'about' parameters, even though these are part of the schema. The description partially compensates but leaves two parameters undocumented in prose, relying on the schema titles alone.

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 clearly states it creates a channel or supergroup, with specific references to the broadcast and megagroup flags. However, it does not differentiate itself from the sibling tool create_group, leaving some ambiguity about when to use this tool versus that one for basic group creation.

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 description implies usage by explaining that broadcast=True creates a broadcast channel and megagroup=True creates a supergroup, giving context for the two primary modes. However, it does not explicitly state when to use this tool over create_group or other alternatives, nor does it mention any exclusions or prerequisites.

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