dakera_session_start

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

No annotations exist, so description must fully disclose behavior. It mentions returning session_id and attaching metadata, but omits details like idempotency, error states, or constraints on multiple sessions. Basic intent is clear, but behavioral depth is insufficient.

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 effectively convey purpose and optional metadata usage. No extraneous information; front-loads the primary action and return 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?

Given no output schema and only 50% schema coverage, the description should provide more context on session lifecycle, error handling, or how session_id is used with siblings. Current text is minimal for a session management tool.

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?

The description adds examples for metadata ('task type or trigger source'), enhancing the schema's weak description. However, it does not explain the required agent_id parameter, leaving its purpose ambiguous.

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 it opens a new session and returns a session_id, distinguishing it from sibling tools like dakera_session_end which ends sessions. The verb 'Open' and resource 'session' are specific.

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 implies usage before storing memories, but no explicit when-not-to-use or alternatives are given. It lacks guidance on prerequisites (e.g., need for agent_id) or comparison with other tools.

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