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

Annotations already flag destructiveHint=true, but the description adds real value by naming the high-stakes actions being gated (real-money trades, spending) and the blocking nature of the decision. It does not, however, discuss reversibility of an approve decision or that the operation is non-idempotent.

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?

Front-loads the auth requirement and the core action, then lists the gated action types. Efficient overall, though the parenthetical '(register_agent, no key needed)' is slightly awkward packaging that adds minor noise.

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 destructive, non-idempotent mutation with no output schema, the description supplies the consequence, auth path, id sources, and the REST twin. Adequate to call it correctly, though it omits any description of the response or error behavior.

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% and the schema already documents approval_id as coming from company_status and api_key from register_agent, so the description's repetition of those sources adds little. The decision enum (approve|reject) and note limit are likewise schema-only.

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 pair (approve/reject) and the exact resource: a pending company action. It enumerates the concrete action types (spending, real-money trade, bug bounty, Build it Better, publishing) and distinguishes itself from company_status by positioning that sibling as the source of approval ids.

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 tells the agent where the approvals come from (company_status) and states the consequence of not acting ('Nothing in that list happens until you approve it'). It covers auth prerequisites (api_key via register_agent) but does not spell out when to reject vs approve or any alternative to this tool.

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