player_quests

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

With no annotations provided, the description carries full responsibility, and it delivers: it discloses that rewards strings are passed through unchanged, that it makes one logical GET request, that it does not auto-fetch pages, that filters are forwarded without guaranteed effectiveness, that arrays are capped at 100 rows/256 KiB with truncation reported, and that oversized records are refused without partial fields. This is exceptionally 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 dense but every sentence adds value: purpose, passthrough behavior, request nature, pagination, policy, filter disclaimer, and limits. It is front-loaded with the core purpose and then details constraints. It is not overly verbose given the amount of behavioral context packed in.

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 tool with one parameter and no output schema, the description covers essential operational details: it is a read operation, it has limits, it does not paginate, and it handles oversized records. It does not describe the structure of 'quest rows' or the exact return format, but that may be implied by the name and is not critical for invocation. It is complete for safe and correct usage.

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 0%, so the description must compensate. The only parameter is 'username,' and the description does not add much beyond the schema—it merely notes that required inputs reflect tool policy, which is generic. The semantics of 'username' are obvious, but no extra guidance or format is provided. This is a baseline-3 situation.

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 clear action ('Read') and a specific resource ('quest rows') scoped to 'one player.' This is specific enough to distinguish it from sibling tools like player_inventory or player_balances, and the verb+resource pattern 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?

There is no explicit guidance on when to use this tool versus alternatives. The description mentions behavioral constraints (e.g., no auto-fetch) but does not say 'use this for quest data, use player_inventory for items' or any similar routing. With many sibling tools, this lack of usage guidance is a clear gap.

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