Project info

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

The readOnlyHint annotation already indicates a safe read operation. The description adds what data is returned but doesn't disclose potential behavior such as response size, performance implications, or whether all items are loaded at once, which is minimal for a simple read tool.

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 a single, front-loaded sentence that directly states what the tool provides and includes a useful 'Start here' guidance. Every word earns its place with no redundancy.

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 fully covers its return values (file path, dirty flag, items, active item) and positions it within the tool family. The 'Start here' hint provides sufficient context for an initial exploration tool.

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?

With zero parameters, there is no schema detail to clarify. The description effectively lists the output contents, compensating for the absence of parameters and adding semantic meaning to the tool's purpose.

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 provides project-level info including specific data fields (file path, dirty flag, all items, active item), distinguishing it from sibling tools like ae_comp_info and ae_layer_info which focus on compositions and layers. The phrase 'Start here' reinforces its role as an entry point.

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?

'Start here' implies this should be the first tool used when exploring a project, but it doesn't explicitly state when to use this vs alternatives like ae_comp_info or ae_catalog. No exclusions or alternative recommendations are given.

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