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

No annotations exist, so the description carries the full burden. It discloses the required X-Org-Api-Key authentication and details the return fields and structure, including a reference to a canonical schema. As a read operation, there are no side effects, and the 'Get' wording makes this clear.

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 a single, information-dense paragraph. It front-loads the main purpose and then lists the returned fields, which is efficient. While somewhat long, every sentence adds value.

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?

In the absence of an output schema, the description thoroughly lists the return fields and references the canonical schema doc. It covers authentication and the shape per protocol. It lacks error handling details, but for a simple getter, this is fairly complete.

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%, so the description must compensate. However, it does not explain any of the parameters (apiKey, orgSlug, session_id) — it only lists return fields. This is a significant gap, as the schema itself provides no additional meaning.

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 clearly states the tool's purpose: 'Get the current lifecycle state of a session' with specific details on what's included (available transitions, state history, SC resolution). This distinguishes it from sibling tools like lifecycle_history and lifecycle_transition.

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 description provides clear context for when to use this tool (to fetch current state), but does not explicitly mention alternatives or exclusion criteria. Given the sibling tools, it's implied when this is appropriate, but explicit guidance would be better.

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