generate_session

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

No annotations provided; description only states it generates a cookie. Does not disclose side effects, authentication requirements beyond 'authenticated', rate limits, or behavior with invalid inputs.

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?

Single sentence with no wasted words, but is too terse and omits crucial details. Could include parameter info in same length.

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?

Despite having an output schema, the description fails to explain parameter semantics or usage context. Incomplete for a tool with 2 undocumented parameters.

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% and description does not explain the parameters (expiration, ipfixed). Adds no value beyond the schema defaults.

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 specifies the action (generate), resource (ljsession cookie), and context (authenticated LiveJournal web endpoints). It clearly distinguishes from sibling tools focused on entries or cache.

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 guidance on when to use vs alternatives, prerequisites (e.g., authentication required), or exclusions. The description lacks context about when this tool is appropriate.

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