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

Annotations give only readOnlyHint=false and destructiveHint=false. The description adds substantial behavior beyond that: authentication prerequisite, the cost of one token per call, and a precise idempotency-recovery policy (reuse key only after a lost response, new key for new execution, do not confuse with a provider-specific idempotency_key field). It does not say what state is created or whether a partial initialization expires, but the operational traits it does disclose are valuable.

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 critical precondition is front-loaded, which is good, but the middle section is dense and slightly muddled (e.g., the odd phrase 'anonymous taste calls' and a somewhat repetitive restatement of the new-key rule). It is longer than needed for two optional parameters.

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?

Auth prerequisites and idempotency are fully covered, but there is no output schema and the description never indicates what the initialization returns or what the natural next step is (none of the sibling tools is named as a follow-up). For an init tool that stages state, that leaves a gap an agent must guess at.

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 100%, so baseline would be 3, but request_idempotency_key's schema description explicitly defers to the tool description ('see the tool description'), and the description fulfills that with concrete reuse semantics. account_link_id is left entirely to the schema, which is acceptable given its detailed description there.

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 specific verb+resource: 'Initialize workplace withdrawal declaration,' which distinguishes it from sibling init tools like business_establishment__init or auto_transfer_unagreement__init by resource. It does not explain what the initialization actually produces or stages for a later call, but the purpose is unambiguous.

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?

It states a hard precondition ('REQUIRES prior fourinsure__session__login call with same account_link_id') and gives clear rules for when to reuse vs create a new request_idempotency_key. No exclusion or alternative-tool guidance is given, but the invocation context is well specified.

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