delete_session

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

No annotations are provided, so the description carries the full burden. It adds a key behavioral detail: returns True if deleted, False if nonexistent, implying idempotency. However, it omits information on side effects, permissions, or error conditions beyond absence.

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 relatively short but includes an 'Args: ctx' line that is absent from the input schema, creating potential confusion. The return behavior line is useful. Overall, it is adequately concise but contains a minor extraneous detail.

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?

The tool is simple (one parameter, no nested objects) and the description covers the primary action and return value. However, it lacks a description of the parameter's semantics and any edge cases. The output schema is present but not shown; given the simplicity, this is acceptable but not thorough.

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?

With 0% schema description coverage, the description must add meaning. It states 'session_id: ID of the session to delete,' clarifying the parameter's purpose. However, it does not specify format, constraints, or validation rules, providing only minimal context.

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 explicitly states 'Delete a workflow session,' providing a clear verb (delete) and resource (workflow session). This distinguishes it from sibling tools like get_session_info, list_sessions, and start_workflow, which have different actions.

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 no guidance on when to use this tool versus alternatives, such as when deletion is appropriate or what prerequisites exist. This leaves the agent without context for tool selection.

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