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

With only readOnlyHint=true annotated, the description carries the behavioral load and does so well: a pending request is not execution, only the signed-in user can approve on the website, and retries must not be automatic. It also discloses client-dependent rendering of structuredContent, which the annotations say nothing about.

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?

Purpose is front-loaded, but the body is a ~250-word wall that mixes tool semantics with agent reply etiquette (Markdown link rendering for Codex/Claude/Cursor, "Do not lead with Yes and then qualify it"). Several sentences address response phrasing rather than invoking or interpreting this call, and the unbroken prose makes the key constraint — copy the real actionId — easy to lose.

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?

With no output schema, the description must explain return values and it largely does, decoding metadata.executionResult.status values (launched, skipped, already_recorded) and what each implies for iteration outcome. Minor gap: it repeatedly says "inspect run history" without naming list_deployment_runs or get_single_trade_status, leaving the agent to pick the sibling itself.

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 coverage is 0% and the single parameter is an undescribed uuid, so the description must compensate — and it does: copy the real actionId from the action tool, never guess it, and a deploymentId/botId/revisionId is not an actionId. That is a meaningful disambiguation error-preventer beyond the schema.

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 and resource ("Returns the status of a pending or completed deployment authorization request") and enumerates the five originating action tools, so the agent knows exactly which objects this reads. It also implicitly separates this from run/telemetry siblings by framing the result as an approval-and-dispatch status rather than execution data.

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?

Gives explicit timing ("Use this after the user approves or denies the website authorization URL"), an explicit anti-pattern ("Do not poll a known unapproved request merely to confirm that approval is still pending"), and a prerequisite ("If no action request has been created or returned, prepare the requested action first"). That is when, when-not, and precondition in one place.

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