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

Annotations declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so the agent knows this is a non-destructive write. Beyond that, the description adds nothing: no word on scheduling behavior, whether the session runs immediately or on the cron interval, whether it requires an existing LLM API key, or what happens on failure.

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?

Two sentences, front-loaded with the action, with zero filler. The endpoint path is redundant but harmless. It is concise to the point of under-specification rather than verbose.

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?

This tool creates a complex, richly parameterized LLM strategy session (15 nested fields, enum-constrained intervals, conditional chart/signal requirements) with no output schema. The description covers none of that context, leaving the agent reliant entirely on reading the 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?

Schema description coverage is reported at 0% for the top-level body parameter, which is itself undocumented. The description supplies no parameter meaning at all — no hint of the required llm_api_id, cron_interval, or prompt, nor the chart/signal/webhook options. It fails to compensate for the 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?

States a clear verb+resource: 'Create a new LLM session'. An agent immediately knows this is a creation operation. However, it does nothing to distinguish itself from siblings such as post_strategy_llm_session_duplicate or post_strategy_llm_session_folder, nor does it explain what an 'LLM session' strategy actually is.

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 when-to-use guidance, no prerequisites, and no mention of alternatives. The agent is not told how this differs from duplicate/folder siblings, nor when a session vs. a strategy code or reaction LLM entity should be created.

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