send_game

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

Annotations already declare readOnlyHint=false, openWorldHint=true, destructiveHint=false, and idempotentHint=false, so the mutation and world-facing nature is partly covered structurally. The description adds nothing about what happens on send, delivery semantics, or failure modes, so it contributes no behavioral context beyond the annotations.

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 sentence is short but that brevity is under-specification rather than economy — there is nothing front-loaded because there is nothing of substance to front-load. No wasted words, but the single sentence carries no 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 10-parameter, 20%-coverage mutation tool with no output schema and no annotations explaining return behavior, the description is wholly inadequate. An agent would need to guess the purpose of most parameters and the expected response.

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 20% across 10 parameters, and the description names none of them. Critical fields like game_short_name, chat_id, message_thread_id, and reply_markup are left entirely to the schema with no explanation of meaning, format, or constraints.

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?

"Send a game." restates the tool name with no additional specification — it does not say what kind of game (Telegram HTML5 game), what the message looks like, or how it differs from siblings like send_gift or set_game_score. An agent cannot distinguish it from other send_* tools beyond the literal token 'game'.

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 prerequisites (e.g., bot must own/attach a game via BotFather), and no mention of alternatives such as send_gift or send_invoice. The agent must infer everything from the name alone.

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