contentrain_init

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

The description discloses a key behavioral trait: changes are auto-committed to git, which adds value beyond the annotations (which only indicate non-read-only, non-destructive, non-idempotent). However, it does not detail idempotency or side effects of repeated calls.

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 extremely concise: two short sentences. Every word is purposeful, with no fluff or redundancy. It effectively front-loads the core purpose and critical warning.

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?

For an init tool, the description covers the primary action and the git commit behavior, which is important context. However, it lacks information about prerequisites, idempotency, and what happens on re-initialization, which would be helpful for completeness given the absence of an output schema.

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?

Input schema has 100% description coverage for all three parameters, so the schema already explains them. The description does not add any parameter-specific meaning beyond what's already in the schema.

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 identifies the tool's purpose: initializing the .contentrain/ structure. It also adds specific behavioral context about auto-committing to git and warning against manual creation, which distinguishes it from sibling tools that perform other operations.

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 provides a warning (do NOT manually create files) but lacks explicit guidance on when to use this tool vs alternatives, such as when the project is first set up or if re-initialization is safe. No mention of prerequisites or when to avoid this tool.

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