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

With no annotations provided, the description carries full burden but only states what the tool does at a high level. It doesn't disclose critical behavioral traits like whether this is a read-only or destructive operation, authentication needs, error handling, rate limits, or what happens during execution (e.g., side effects, output format).

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, efficient sentence that front-loads the core action. Every word earns its place by conveying key aspects like 'project-aware', 'overrides', and 'OS translation' without redundancy or fluff.

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 tool with 4 parameters, nested objects, no annotations, and no output schema, the description is inadequate. It lacks details on execution behavior, error cases, return values, and how it integrates with sibling tools, leaving significant gaps for an AI agent to understand proper usage.

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 description coverage is 75%, providing good baseline documentation. The description adds minimal value beyond the schema by mentioning 'project overrides and OS translation', which loosely relates to 'projectName' and 'commandKey', but doesn't explain parameter interactions or provide additional context for the 4 parameters.

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 'executes' and the resource 'command', with additional context about 'applying project overrides and OS translation'. It distinguishes from siblings like 'translateCommand' by emphasizing execution rather than just translation, but could be more specific about what type of commands it handles.

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 explicit guidance on when to use this tool versus alternatives like 'getProjectCommands' or 'translateCommand'. The description implies usage for executing commands with project context, but lacks clear boundaries, prerequisites, or exclusions for sibling tools.

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