generate_handoff_brief_tool

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

Describes writing a file and capturing specific data, which is transparent for a read-mostly operation. However, with no annotations, it should disclose potential side effects (e.g., overwriting files), preconditions (e.g., existence of a journal entry), or failure modes. The description leaves some behavioral ambiguity.

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?

Extremely concise: three short sentences covering purpose, captured data, and usage scenario. Each sentence adds value with no wasted words. The structure is front-loaded and easy to scan.

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 the tool's low complexity (one optional param, has output schema), the description covers most relevant aspects: the brief's contents, file location, and usage timing. However, it omits parameter semantics and any preconditions, making it not fully 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?

The only parameter, session_id, is optional with a default empty string, but the description provides no explanation of its purpose or expected value. With 0% schema description coverage, the description fails to add meaning beyond the schema, which is a significant gap for effective tool invocation.

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 generates a portable session handoff brief, listing specific captured data and output location. However, it does not explicitly differentiate from similar sibling tools like save_session_summary or consolidate_session_memory, missing a chance to clarify its unique role.

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?

Explicitly recommends using this tool when a session is ending, before /clear, or when switching AI/device. This is good contextual guidance, though it omits when not to use it or mention of alternatives.

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