init_project_graph

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the tool overwrites existing graphs, creates/persists a state file, how validation commands are executed, or what side effects occur. For a mutation tool with 5 parameters, this is a significant gap.

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 front-loaded with the key action and includes a compact list of what the graph contains. There is no redundancy or fluff, making it highly concise and well-structured.

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 complexity (5 params, nested node objects) and lack of an output schema, the description is insufficient. It does not explain the tool's behavior, what happens after initialization, how state persistence works, or what the agent should expect as a result. This under-specification makes it hard for an agent to invoke safely.

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?

The input schema has 100% parameter description coverage, so the schema already documents all parameters. The description's mention of task nodes and validation commands adds minimal value beyond the schema, and no additional semantic detail is provided for parameters like projectRoot or stateFilePath.

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 ('Initialize') and clearly identifies the resource ('project workflow graph') along with key components (task nodes, phase milestones, dependencies, validation commands). This distinguishes it from sibling tools like add_task_node or get_graph_state, which serve different purposes.

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 'Initialize a new' provides clear contextual guidance that this tool is for creating a new graph, not modifying an existing one. However, it does not explicitly mention alternatives or exclusion cases (e.g., when to use add_task_node instead), though the 'new' qualifier provides reasonable clarity.

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