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

Annotations are empty, so the description carries the full burden. It states the tool 'Returns' a playbook, implying a read-only operation without side effects. However, it does not disclose any limitations, required permissions, or whether there are any side effects. For a retrieval-style tool, this is adequate but not rich in behavioral 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?

The description is a single sentence that is dense but not overly long. It front-loads the key fact that this is a namespaced alias for start_here, then lists the content areas efficiently. Every phrase contributes to describing the tool's output, with minimal wasted text.

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 43 parameters, no output schema, and no annotations, the description is relatively sparse. It gives a high-level summary of what is returned but does not explain how to invoke the tool (e.g., whether parameters like 'audience' are relevant), nor what the response structure looks like. For a complex schema, this is insufficient for an agent to know how to correctly use the tool.

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 only 33%, and the description adds no parameter-specific guidance. The tool has 43 optional parameters, and the description does not explain which are relevant for this tool or how they affect the returned playbook. Since coverage is low, the description should compensate, but it does not, leaving parameter semantics largely unexplained.

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 tool 'Returns the agent operating playbook' and lists specific content areas, giving a specific verb and resource. It identifies itself as a 'Namespaced alias for start_here', which helps distinguish it from sibling tools. However, it doesn't explicitly differentiate from other playbook-related tools like wisely_get_playbook, so it loses a point.

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?

Usage is implied by the name and the mention of 'first-call order', suggesting this is the entry point. The description lists what is returned but does not explicitly state when to use this tool over alternatives or provide exclusions. It says it is an alias, which implies using the wisely-namespaced version, but no direct 'use this when' guidance is given.

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