validate_tileset_catalog

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool reports specific categories of problems, which gives the agent a good sense of what to expect. It also explains the effect of the strict parameter. It does not explicitly state whether the tool modifies anything or is read-only, but the verb 'validate' implies a non-destructive analysis. This is adequate but could be more explicit about side effects.

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 concise and front-loaded. The first sentence states the core purpose, and the second sentence details the strict behavior. It lists specific problem categories in a compact, scannable list without unnecessary words. Every sentence earns its place, making it an efficient and well-structured description.

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 validation tool with only two simple parameters, the description is complete. It explains what the tool validates, what it reports, and how the strict parameter changes behavior. No output schema exists, so the description adequately covers the return value expectations by listing the types of issues reported. The lack of nested objects or complex params means no further documentation is needed.

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 input schema already provides 100% coverage with descriptions for both parameters, so the baseline is 3. The description adds the phrase 'strict=true requires every regular tile to have a reviewed entry,' which essentially restates the schema's description of the strict parameter. No additional meaning is introduced beyond what the schema already offers, but it also does not detract from 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?

The description states a specific action ('Validate') and a specific resource ('tileset catalog against its engine manifest'), and enumerates the exact categories of problems it checks (invalid ids, malformed object grids, contradictory layer/priority choices, transparent z0 placement, unreviewed tiles). This clearly distinguishes it from sibling tools like verify_tileset or validate_assets, which target different resources or validation scopes.

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?

The description clearly implies when to use the tool: to validate a tileset catalog before using it in the engine. It provides the context of what validation entails but doesn't explicitly name alternatives or exclusions. The mention of 'strict=true' also gives a conditional usage note, which helps the agent decide when to employ that parameter. However, it does not explicitly say 'use this instead of X'.

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