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

The description adds some behavioral details (validation, file permissions, request closure) beyond the all-false annotations, but these are cryptic. It does not explain what 'store' means, what happens to the request, or any side effects. Since annotations provide no safety profile (all false), the description carries the burden but fails to adequately disclose the mutation and its implications.

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 extremely brief, which is technically concise, but it is a run-on list of actions without structure or context. It does not front-load a clear purpose and leaves the agent to infer meaning, making it more under-specified than genuinely concise.

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?

Despite having an output schema, the description is incomplete for a mutation tool with all-false annotations. It omits when to use it, what the token and request_id represent, what 'complete' entails, and any prerequisites. An agent cannot reliably call this tool without additional context.

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 must explain the two required parameters. It mentions 'pasted token' (loosely mapping to token) and 'close request' (mapping to request_id) but offers no details about formats, expected values, or how they interact. This is insufficient compensation for the absent schema descriptions.

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 lists three actions ('validate a pasted token live, store chmod 600, close request') without a clear, single-purpose statement. It gives a vague sense of completing an account link but does not explicitly say 'completes an account linking process' or what the resource is. The name and title are slightly clearer, but the description itself lacks specificity.

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?

No guidance is provided on when to use this tool versus siblings like accounts_connect, accounts_wait, or accounts_remove. The description gives no context about the linking flow, prerequisites, or exclusions, leaving the agent without direction.

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