write_matrix_entry

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 merely says 'Write entry', which does not reveal whether the operation creates, updates, overwrites, requires special permissions, or has any side effects beyond the obvious mutation.

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 technically brief and free of fluff, but it is under-specified and functions more as a title than an operational description. There is no structural information that helps an agent plan or validate the call.

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?

With no output schema, no annotations, 0% schema description coverage, and no mention of how this tool relates to siblings like query_matrix or write_file, the description leaves nearly everything to inference. This is inadequate even for a simple two-parameter tool.

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%, and the description does not mention topic or content at all. The agent receives no explanation of what these parameters mean, how they relate to each other, or what format or constraints the values should satisfy.

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 states a clear action ('Write entry') against a specific resource ('Knowledge Matrix'), and the verb distinguishes it from the sibling query_matrix. However, it does not explain what an 'entry' consists of beyond what the schema implies, so it is clear but not fully specific.

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?

There is no guidance on when to use this tool versus alternatives such as query_matrix or write_file, no mention of prerequisites, and no explicit exclusions. An agent must infer the intended usage from the tool name and the one-line description.

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