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

Annotations already declare readOnly=false, destructive=false, idempotent=false and closed-world, so safety is covered structurally. The description adds genuinely useful context beyond them — the fixed $0.05 per-call price — but says nothing about what classification labels are produced, whether the response is a draft or sent output, or any limits.

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 core action is front-loaded in the first sentence and the price note is compact. The fragment 'Handling support messages consistently' is filler that earns little, but total length is tight.

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 should describe the return shape (what categories it classifies into, what the suggested response looks like), and it doesn't. Combined with the undocumented 'policy' parameter, an agent cannot invoke this reliably.

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 0%, so the description must compensate — and it only implies that 'message' is the complaint. The 'policy' parameter (an optional string governing the response) is never explained anywhere, leaving an agent to guess how to populate it.

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 and resource: 'Classify a complaint and suggest a response.' An agent can tell it is a complaint-handling tool, though it doesn't distinguish itself from the nearby sibling fikra_generate_customer_response.

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 when-to-use, when-not-to-use, or alternative guidance. The trailing phrase 'Handling support messages consistently' gestures at a domain but does not tell the agent when to pick this over fikra_generate_customer_response or fikra_generate_business_report.

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