get_project_summary

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

No annotations are provided, so the description bears the full burden of disclosing behavioral traits. It does not state whether the tool is read-only, what side effects it may have (e.g., scanning the entire project could be resource-intensive), or what the output format looks like. The phrase 'analyze and summarize' is vague about the actual behavior beyond the high-level intent.

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, concise sentence that is front-loaded with the key action ('analyze and summarize') and resource ('entire project'). Every word contributes to understanding the tool's purpose, with no filler or redundant content.

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?

The tool has no output schema, so the description should ideally clarify what the summary includes or how it is returned. It does specify the scope (structure, technology) but does not mention the output format, potential size of the summary, or any caveats about analyzing large projects. Given the simplicity of a parameterless tool, this is a minimal but not complete description.

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 tool has zero parameters, and the input schema is empty. The description adds no parameter-specific semantics, but none are needed. With 100% schema coverage (trivially) and no parameters to document, the baseline of 4 applies because the description is not required to compensate for missing parameter information.

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's function: 'analyze and summarize the structure and technology of the entire project.' It uses specific verbs and resources, making the core purpose obvious. However, it does not explicitly distinguish itself from sibling tools like project_audit or code_metrics, which could also involve analysis, so it falls short of a 5.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or scenarios where another sibling tool would be more appropriate. There is no explicit 'when to use' or 'when not to use' context, leaving the agent to infer usage from the tool name alone.

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