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

Annotations provide idempotentHint=true, and description adds that it 'reports the result,' which clarifies output. However, description does not disclose potential side effects like file generation (e.g., target directory) or what exactly the result contains (e.g., success/failure, logs). With annotations covering safety, the description adds minimal context.

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?

Single sentence, no waste. All information is front-loaded and succinct. Every word serves a purpose.

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 simple build tool with one parameter and no output schema, the description covers the main action but omits details on failure handling, return value format, or any subsequent steps. Could be more helpful with brief mention of typical output structure.

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 parameter 'project_path' has a clear description. The tool description does not add any additional meaning beyond the schema, so baseline of 3 is appropriate. No extra info on format, constraints, or examples.

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 clearly states the tool runs 'bal build' on a project directory and reports the result. It distinguishes from sibling tools like 'sf_deploy_project' (deploying) and 'sf_scaffold_project' (scaffolding), providing a specific verb-resource combination.

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 on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., project must have been scaffolded), expected state before building, or when other tools like 'sf_deploy_project' would be more appropriate. Lacks explicit when-not-to-use or alternative references.

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