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

Annotations already declare destructiveHint=true, readOnlyHint=false, openWorldHint=true, and idempotentHint=false, so the safety profile is largely covered. The description adds genuinely new context (a human review request is produced; credentials are entered privately), but the phrase 'Idempotent request_id' sits oddly against idempotentHint=false and is not reconciled, and no retry/review-turnaround behavior is described.

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?

Three short sentences with no filler, and the most important fact (it returns a review request, not a result) is front-loaded alongside the core action. It errs toward under-specification rather than 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?

This is an 8-required-parameter, no-output-schema tool in a human-review workflow, and the description says nothing about the review lifecycle, what happens after submission, how to poll for the decision, or what fingerprint/revision must match. For a destructive, open-world operation with low schema coverage, this is materially incomplete.

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?

Only 2 of 8 parameters (25% coverage) carry schema descriptions, so the description is expected to compensate and largely does not. 'Approved input and expected output' loosely maps to the input and expected_structured_output params, but tool_id, revision, fingerprint, and connection_id are unexplained in both the schema and the description.

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 states a concrete action (test an exact tool with approved input and expected output) and then clarifies the actual output shape: a secure human review request rather than an immediate execution result. That second sentence is what makes the purpose distinguishable from the sibling register/update/publish custom-tool tools, though the phrase 'exact tool' is idiosyncratic and the sibling relationship is never named.

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 statement of when to call this versus beon_register_custom_tool, beon_update_custom_tool, or beon_publish_custom_tools, and no prerequisites (e.g., tool must already be registered) are given. The agent must infer usage entirely from the name.

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