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

No annotations are provided, so the description carries full burden. It mentions 'append|replace semantics' which gives some behavioral context about mutation modes, but doesn't disclose critical information like required permissions, whether this creates new entities or modifies existing ones, error conditions, or what the unified API entails. For a write operation with zero annotation coverage, this is insufficient.

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, efficient sentence with zero wasted words. It's front-loaded with the core purpose and includes the key behavioral detail about append/replace semantics. Every element earns its place.

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 4 required parameters with 0% schema coverage, no annotations, but an output schema exists, the description provides basic purpose and mode information. However, for a write operation that likely creates or modifies content, it should explain more about the entity_id relationship, content_type options, and behavioral implications. The output schema reduces but doesn't eliminate the need for more context.

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 description coverage is 0%, so all 4 parameters are undocumented in the schema. The description mentions 'append|replace semantics' which hints at the 'mode' parameter's purpose, and 'narrative content' relates to 'content' and 'content_type', but doesn't explain 'entity_id' or provide details about parameter formats, constraints, or relationships. It adds some meaning but doesn't adequately compensate for the complete schema coverage gap.

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 action ('Write narrative content') and resource ('content'), specifying it's done via a unified API with append/replace semantics. It distinguishes from obvious siblings like 'append_content' by mentioning both modes, but doesn't explicitly differentiate from all potential alternatives like 'update_entity' or 'upsert_entity'.

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 mentions 'append|replace semantics' which implies usage context, but provides no explicit guidance on when to use this tool versus alternatives like 'append_content' (which appears to be a sibling), 'update_entity', or 'create_entity'. There are no when-not-to-use statements or clear prerequisites.

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