send_telegram_update

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the meaningful side effect — an outbound message delivered to the user's external Telegram — but says nothing about delivery failure, rate limits, whether the call blocks, or what happens if the user is unreachable.

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 sentences, zero waste, with the core action front-loaded and the usage conditions following. Every clause earns its place.

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 notification tool with full schema coverage and no output schema, the description covers purpose and timing adequately. It is slightly short on operational behavior (delivery semantics, failure handling), which is the only meaningful gap.

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 parameters (including the status enum) are already documented in the schema. The description lists update categories that loosely correspond to the status values but adds no format, length, or constraint guidance beyond the schema, so the baseline of 3 is correct.

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 ('Send') and resource ('vital update, progress log, or status notification') with the destination ('the user's Telegram'). There are no sibling tools to disambiguate from, and the action is unambiguous to an agent without opening the schema.

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?

Explicitly enumerates trigger conditions: starting a long task, reaching significant milestones, encountering a blocker, or needing the user back at the computer to approve an action. This maps directly onto the 'action_required' status and leaves no inference required about when to call it.

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