contentrain_content_save

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

Annotations indicate idempotentHint=true, and the description adds that changes are auto-committed to git, warns against manual edits, and explains field handling per model. No contradictions.

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 somewhat lengthy but well-organized with clear sections per model kind. Every sentence adds value, though it could be slightly more compact.

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 complexity of four model kinds and the git commit behavior, the description covers all necessary usage details. No output schema is needed as the return is implied.

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?

With 100% schema coverage, the description significantly enriches parameters by explaining model-specific behaviors (e.g., 'id' and 'slug' ignored for DICTIONARY, 'body' key for documents) that are not 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 states 'Save content entries' and elaborates on four model-specific formats (DICTIONARY, COLLECTION, DOCUMENT, SINGLETON), distinguishing this tool from siblings like list or delete.

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 detailed format guidance per model kind, which helps the agent choose the correct usage, but it does not explicitly state when to use this tool versus alternatives like contentrain_bulk or contentrain_apply.

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