Submit Telegram two-step password

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

Annotations declare readOnlyHint=false and openWorldHint=true, so the mutating, externally-dependent nature is already visible. The description usefully adds the conditional 2FA requirement, but says nothing about failure behavior for an incorrect password, attempt limits/flood waits, or the effect on session state, which matter a great deal for an auth credential submission.

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?

One short sentence with the action front-loaded and the only meaningful condition attached. Nothing redundant and nothing that could be trimmed 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 one-parameter tool with full schema coverage and no output schema, the description covers what it does and the key precondition. The remaining gap is flow placement relative to auth_start and auth_code and error handling, which are useful but secondary for a tool this simple.

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?

There is a single parameter with 100% schema description coverage, so the schema already explains that it is the Telegram two-step verification password. The description adds no format, source, or handling guidance beyond that, which is the expected baseline when the schema does the work.

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 specific verb (submit) and a specific resource (the two-step verification password), which clearly separates it from siblings such as auth_code (login code) and auth_status. It stops short of explicitly naming those siblings as alternatives, so it is clear but not maximally differentiated.

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 clause 'if the account has one enabled' gives a real precondition, which is more than most definitions offer. However, it never states where this sits in the auth flow (after auth_start/auth_code), how to determine whether 2FA is enabled, or what to do if submission fails, so the agent must infer sequencing.

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