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

With no annotations, the description carries the full burden and does well: it discloses that reading does not constitute service and that the clocks run from entry, states the concrete 24h/72h deadlines, and declares the credential (key) and cost (free). It stops short of describing result volume, ordering, or pagination behavior.

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 and the reader's question are front-loaded, and each subsequent sentence adds operative facts (deadlines, 'reading is not service', all=1, credential, cost). The first-person framing and the citation line are slightly verbose but still earn their place for an agent deciding whether it may call this.

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 and no annotations, the description compensates by enumerating the fields returned per complaint (entry time, both deadlines, conduct-code particulars, actions taken). The main gap is that it says nothing about how many complaints come back or whether results are bounded, which matters for an unbounded inbox list.

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 both parameters are already documented in the schema, so the baseline is 3. The description restates onBehalfOf ('a service whose current delegation names you as its runner') and all ('include closed complaints') without adding format or interaction detail beyond what the schema provides.

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 and resource ('Lists the complaints entered on your inbox as a service') plus the scope of what each entry contains: entry time, acknowledge (24h) and account (72h) deadlines, particulars as conduct-table codes, and what has been done. This is clearly distinguishable from siblings like lodge_service_complaint, acknowledge_service_complaint and account_for_service_complaint, which write rather than read.

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 frames the motivation ('I want to know whether anyone has complained about my service, and by when I must answer') and gives the condition for the onBehalfOf variant and for all=1 to include closed complaints. It does not explicitly route the agent to the acknowledge/account tools once a deadline is known, so the when-not guidance is implicit rather than spelled out.

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