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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the raw HTTP path and no behavioral context such as error handling, what a missing ID returns, or any auth requirements, so it contributes little beyond structured fields.

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 terse fragments, front-loaded with the operation and scoped by ID. No filler, though the endpoint string is arguably redundant given the tool name.

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 trivial single-parameter read with no output schema and annotations covering safety, the definition is minimally adequate. It omits any indication of what the folder object contains or whether the call can fail, but nothing critical to invocation is missing.

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?

There is a single required parameter with 100% schema description coverage ('Folder ID'), so the schema carries the semantics. The description's 'by ID' adds nothing beyond the schema, which is the expected baseline-3 case when coverage is high.

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 specific verb (get) and resource (LLM session folder) scoped by ID, and the endpoint path reinforces it. It is clear what the tool fetches, though it does not explicitly differentiate from close siblings like get_strategy_llm_session_folder (list) or get_strategy_llm_session_folder_root, relying on the name alone.

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 versus the sibling folder tools (get_strategy_llm_session_folder, get_strategy_llm_session_folder_root, get_strategy_llm_session_id). The description only echoes the resource and endpoint, leaving selection entirely to the reader.

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