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 nothing beyond that – no note on whether the session must be public, whether it returns 404 for private sessions, or any auth requirement.

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?

Four words with no filler and no buried information, so nothing is wasted. However, the brevity borders on under-specification for a retrieval tool with an undocumented required parameter rather than being efficiently minimal.

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 and an undocumented parameter, the description should explain what a returned session contains or how the id is obtained. It provides none of that, leaving the agent unable to call the tool correctly beyond guessing that `id` is a session identifier.

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 coverage is 0% for the single required `id` parameter, so the description carries the full burden. It merely implies the id refers to a session but never states the id type, source, or what qualifies a session as "public", leaving the parameter effectively undocumented.

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 "Get public llm sessions" essentially restates the tool name without adding scope or verb specificity. It also conflicts subtly with the schema, which requires a single numeric `id`, while the description uses the plural "sessions". An agent cannot tell from this text how it differs from the sibling `list_all_public_llm_session`.

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?

No when-to-use guidance and no mention of alternatives, despite several closely related siblings (`list_all_public_llm_session`, `get_strategy_llm_session_id`). The agent is left to infer that this retrieves a single session by id purely from the required parameter.

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