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

No annotations exist, so the description bears the full burden. It implies a read operation but says nothing about pagination, ordering, result limits, permissions needed, or what an empty result means — all relevant for a listing tool with an undocumented required identifier.

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?

One short sentence with no filler, so nothing is wasted. But the terseness reflects under-specification rather than disciplined conciseness — there is no front-loaded scope detail beyond "for a project."

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 two-parameter tool with no annotations, no output schema, and an undocumented required parameter, the description should carry much more context. As written, an agent cannot confidently determine required input format or what the listing returns.

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 only 50%: notification_message is documented in the schema, but the required publisher_pid has no description anywhere and the tool description does not explain it (project id? publisher id? format?). With the single required parameter left ambiguous, the description fails to compensate for the coverage gap.

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 names a verb ("List") and a resource ("research report files") scoped "for a project," so the basic operation is discernible. However, it gives no signal for distinguishing this from close siblings like list_project_assets or get_research_status, leaving the agent to infer the boundary.

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 statement of when to use this tool versus the many neighboring list_* tools (list_project_assets, list_project_drive, list_projects) or research-related tools. No prerequisites or exclusions are given; usage is entirely inferred from the name.

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