init_context_graph

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

With no annotations, the description must disclose side effects. 'Fresh' hints at creating new files but does not clarify whether existing files are overwritten or if the tool fails when a graph exists. No mention of permissions or other behaviors.

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 with no fluff, front-loading the key action. It communicates the core purpose efficiently.

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?

While the output schema exists, the description is incomplete for a tool with four parameters and no annotations. It lacks guidance on parameter meanings, failure modes, and the relationship to existing workspace state, making it insufficient for an agent to invoke confidently.

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 schema has no descriptions for any of the four parameters, and the tool description doesn't explain project_name, description, scope, or workspace_path. At 0% schema coverage, the description must compensate but doesn't.

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's function: initializing a fresh .context/ memory graph with specific files. The verb 'Initialize' and the resource '.context/ memory graph' are specific and distinguish it from sibling tools that operate on an existing graph.

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 implies the tool is for bootstrapping a new workspace memory graph, but doesn't explicitly state when to use it versus sibling tools like create_module_node or update_node. No exclusions or alternative scenarios are provided.

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