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

With no annotations provided, the description carries the full burden of disclosing behavior. It explicitly states the operation is 'deterministic' and 'read-only,' which meaningfully conveys the safety and reproducibility profile. It does not mention auth, rate limits, or whether the checklist is persisted, but the read-only claim covers the most important behavioral trait.

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 with no filler words. It is concise, though it omits key input semantics, so it earns high marks for structure but not perfection.

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?

The output schema covers return shape, but the description leaves the required playbook_id unexplained and does not reference sibling tools like recipes_playbooks_list or recipes_playbook_get for obtaining it. The relationship between finding and playbook_id is also unclear, making the tool difficult to invoke correctly without external knowledge.

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 0%, so the description must compensate, but it only hints at 'finding' and never explains the required 'playbook_id' parameter. An agent cannot determine what a valid playbook_id is, how it relates to the finding, or what the default null finding means.

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 uses a specific verb ('Build') and names a concrete deliverable ('phase, gate, and evidence checklist') for a finding. It is clearly distinct from sibling tools like recipes_playbook_get or recipes_playbooks_list, though it does not explicitly name any sibling for differentiation.

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 phrase 'for a finding' implies when the tool should be used, but it does not state prerequisites, exclusions, or alternatives. An agent is left to infer that this is for planning rather than executing or retrieving a playbook, with no explicit guidance on when not to use it.

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