List files inside a remote asset bundle

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

The description adds behavioral context beyond annotations: it mentions HTTP byte ranges, return of entry paths and sizes, and that signed URLs are never exposed. This complements the readOnlyHint=true annotation without contradiction.

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 two sentences, front-loaded with the main action, and every word adds value. No unnecessary information is present.

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?

Given the tool's simplicity (two parameters, simple list output), the description covers the key return values (entry paths and sizes) and a security note. The presence of an output schema reduces the need to detail return structure. Minimal gaps.

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 has two parameters (packId, uploadId) with 0% description coverage. The description does not explain what packId or uploadId represent or how they relate to the 'curated itch.io ZIP,' leaving the agent without parameter guidance.

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 clearly states the tool inspects a curated itch.io ZIP via HTTP byte ranges, listing entry paths and sizes. The verb 'inspect' and resource 'curated itch.io ZIP' align with the title 'List files inside a remote asset bundle,' and the purpose is distinct from sibling tools like download or search.

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 implies use for inspecting bundle contents without full download, but it does not explicitly state when to use this tool versus alternatives (e.g., asset_download_bundle_entry). No comparison or exclusion criteria are provided.

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