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

No annotations are provided, so the description must disclose behavioral traits. It describes the artifact as 'persistent' and includes a detailed approval tier note about first use, manager approval, and approval types. This adds meaningful behavioral context beyond the schema.

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 concise with two clear sentences plus a brief approval note in brackets. It front-loads the purpose and usage guidance. The bracketed note, while informative, slightly disrupts flow but is justified by its importance.

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?

Given the tool's simplicity (3 required params, no output schema), the description covers purpose, when to use, and behavioral details. It lacks specifics on what happens after invocation (e.g., return value or artifact ID), but for an initialization tool this is sufficient for agent decision-making.

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% with descriptions for all three parameters. The description does not add significant meaning beyond the schema—it mentions 'persistent Master Plan artifact' but does not elaborate on parameter usage or constraints. Baseline is 3 due to high schema coverage.

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 ('Initialize') and resource ('a new multi-step project with a persistent Master Plan artifact'). It provides a directive to call this before complex tasks. However, it does not explicitly differentiate from sibling tools like 'create_folder' or 'create_feature', which could cause ambiguity for an AI agent.

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 'Call this BEFORE starting any complex, multi-tool task', giving clear when-to-use guidance. The approval note adds context about permission requirements. However, it lacks explicit 'when-not-to-use' or alternative tool references.

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