nodejs_project_info

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

No annotations are present, so the description must fully disclose behavioral traits. It states only that the tool 'gets' information, but does not clarify whether it modifies files, runs external commands, or has side effects. Critical details like read-only nature or error handling are omitted.

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 efficiently conveys the tool's purpose. It is concise with no wasted words. A slightly more structured presentation could improve clarity, but it remains effective.

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 large number of sibling Node.js tools and the absence of an output schema, the description is insufficiently complete. It does not explain what 'comprehensive' entails, the return format, or how it relates to other analysis tools. More context is needed for an agent to use it correctly.

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 100% and the parameter description ('Working directory to analyze') is clear. The tool description adds the context of Node.js projects but does not provide additional meaning beyond the schema. Baseline score of 3 is appropriate.

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 verb 'Get' and resource 'comprehensive Node.js project information', listing specific items (package.json, dependencies, frameworks). However, it does not explicitly differentiate from the similar sibling tool 'nodejs_package_info', which could cause confusion. Score is high but not maximum due to missing sibling distinction.

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?

No guidance is provided on when to use this tool versus alternatives like 'nodejs_package_info' or 'detect_project'. The description lacks any context about prerequisites, appropriate scenarios, or exclusions, leaving the agent without decision support.

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