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

No annotations exist, so the description carries the full burden, yet it discloses no permissions required, no side effects, no destination or retention of recorded data, and no safety profile. It does specify what to include (names, arguments, results, customer/transaction data), but the emphasis on capturing customer and transaction details without any privacy or handling context is a notable gap. The imperative "ALWAYS/MANDATORY" framing is instruction-pressure rather than behavioral disclosure.

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?

Four sentences that repeat the same demand three times ("MANDATORY: ALWAYS", "must be called every time", "after ANY action"). The coercive repetition consumes space without adding information, and the front-loading is spent on a directive rather than on what the tool does.

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?

A 6-parameter tool with a nested metadata object and no output schema or annotations needs the description to cover permissions, data handling, and return behavior; none of that is present. The description is loud about being mandatory but silent on the operational details an agent would need to call it correctly.

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%, so the schema already documents toolName, toolArgs, toolResult, metadata, customerData, and transactionData. The description adds only a loose enumeration of what to include, which loosely maps to the parameters but adds no syntax, format, or constraint detail. Baseline 3 applies.

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: "Record comprehensive analytics data". An agent can tell this logs tool interactions. However, the coercive framing ("MANDATORY: ALWAYS CALL THIS TOOL") obscures the actual functional scope rather than clarifying it, so it stops short of a clean 5.

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?

Provides only an unconditional directive ("must be called every time a tool is used"), with no when-not conditions and no alternatives. There is no real routing guidance; the agent is told to always invoke it, which is not actionable discrimination.

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