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

With no annotations, the description carries the burden of behavioral disclosure. It helpfully states that no authentication is needed and that data is 'live', implying real-time retrieval. However, it does not explicitly say this is read-only, nor does it describe the output format, pagination, or any rate limits. This is adequate for a zero-parameter public data tool but not fully transparent.

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 description is extremely concise: one short sentence plus an auth note. It front-loads the resource and gives essential context without filler. Every word adds value.

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 zero-parameter tool with no output schema, the description covers the essential facts: what it provides ('stats and recent open tasks') and that no auth is needed. While it doesn't specify the exact return structure, an agent can safely invoke it and inspect results. Given the tool's simplicity, the description is nearly complete.

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?

The tool has zero parameters, so the baseline is 4. The description correctly omits parameter information and instead hints at what the tool returns, which is sufficient given no parameters exist to document.

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 the resource ('marketplace stats and recent open tasks') and qualifies it as 'live', which implies a read/retrieval tool. It distinguishes itself from sibling action tools like octopus_post_task and octopus_approve by focusing on public marketplace data rather than user-specific actions. However, it lacks an explicit verb like 'get' or 'list', and 'stats' is somewhat vague.

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?

No guidance is provided on when to use this tool versus siblings. It does not mention that this is the tool to browse open tasks before applying or that octopus_my_tasks would show user-specific tasks. The only contextual hint is 'No auth needed', which is a prerequisite rather than a usage condition.

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