create_log

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

Annotations already convey the safety profile (readOnly false, idempotent true, destructive false), and the description adds that this operation targets the Plex Media Server log and accepts multi-line content. It does not cover response handling, authentication, or side effects, but given annotation coverage this is an acceptable baseline.

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 short and front-loaded: the first sentence states the purpose, followed by the endpoint and a compact parameter note. Every line adds useful information, and there is no filler or redundant wording.

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 a tool with one open-world body parameter, existing output schema, and comprehensive safety annotations, the description is mostly sufficient. It explains the action, names the endpoint, and directs the agent to the right place to discover body fields. It is slightly thin regarding choice between this and the closely related create_log_networked and update_log tools, but the core invocation path is covered.

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 only parameter, body, is an opaque object with additionalProperties true, and schema description coverage is 0%. The description labels it 'Request payload' and tells the agent to look at the /schema endpoint, but it provides no concrete meaning for the body structure or fields. This leaves the agent dependent on external discovery rather than the tool definition itself.

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 opening sentence states a specific action (logging a multi-line message) and a specific target (the Plex Media Server log), which clearly communicates what the tool does. It does not explicitly compare against closely related siblings like update_log or create_log_networked, so it stops short of full differentiation.

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 use case is unambiguous: posting a log message to the Plex server. It also gives a clear prerequisite by telling the agent to read the matching GET or /schema endpoint before supplying the body, which is practical guidance. It does not mention alternatives or when-not conditions, but the context is clear enough.

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