Project summary

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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds useful context beyond that: it reports password/signing status and notes that each module carries a content_token for a guarded write, which is exactly the kind of behavioral detail an agent needs when planning follow-up actions.

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?

Two sentences accomplish the full job: the first states the aggregate scope and its contents, the second gives explicit usage timing and the token behavior. Everything earns its place and the key instruction is front-loaded.

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?

With an output schema present, the description doesn't need to document return shapes. The only required input is fully specified in the schema, and the description supplies the workflow context and token guidance that aren't available anywhere else.

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?

There is only one parameter and the schema already documents it as an absolute file path, so schema coverage is 100%. The description doesn't add new parameter semantics beyond confirming that the call targets one Office file, so the baseline score applies.

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?

Description names a specific action and resource: it gathers all project-level information about one Office file in a single call. It enumerates the returned categories (VBA modules, UserForms, queries, worksheets, protection status), which makes its scope concrete and distinguishes it from the more granular list_* and read_* siblings.

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?

'Call this once per file before working on it' gives explicit positioning as the first step in a workflow. It doesn't spell out when to prefer a sibling tool instead, but the 'everything in one call' phrasing makes the aggregate-vs-specific distinction clear.

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