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

With no annotations provided, the description carries the burden. It discloses the read-only nature via 'read' and explicitly lists the return shape: { profile, source, confidence, updated_at }. This gives the agent a good sense of behavior, though it does not cover edge cases like missing profile or error handling.

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 two short sentences, front-loaded with the core action and resource. Every sentence adds value: the first defines the operation and return, the second gives the usage context.

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 read tool with one optional parameter and no output schema, the description adequately covers purpose, usage, and return shape. It could be more complete by noting behavior when no profile exists, but it is sufficient for an agent to use the tool 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% for the single optional workspaceId parameter, so the schema already documents it. The description does not add extra parameter-specific details, but none are needed given the simple optional workspace-scoping.

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 'read the workspace's stored company profile', specifying both the action and resource. It also distinguishes from siblings like chieflab_set_company_profile by emphasizing 'read' and 'stored', and adds the specific use case 'before launch'.

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 explicitly says 'Use before launch to confirm what ChiefLab will ground in', giving clear timing and context. It does not mention when not to use it or alternative tools, but the guidance is sufficient for common use.

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