delimit_session_handoff

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

No annotations provided, so the description must disclose all behavioral traits. It mentions storing items but fails to describe persistence behavior (e.g., overwrite vs. append), authorization needs, or side effects, creating significant gaps.

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?

Three concise, front-loaded sentences with zero redundancy. Each sentence serves a distinct purpose: what it does, when to use, and what it stores.

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?

Output schema exists, covering return values. The description covers purpose and usage but lacks behavioral details like session persistence or merging behavior. With 7 parameters, more context on tool lifecycle would improve completeness.

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 100%, so baseline is 3. The description maps parameters to session summary components but adds little beyond the schema's own descriptions. It does not explain formats or constraints in more detail.

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?

Clearly states the tool saves a session summary for cross-session continuity with a specific verb and resource. While it distinguishes from sibling tools by focusing on end-of-session saving, it could explicitly differentiate from other handoff tools like delimit_handoff_create.

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 advises calling at the end of a productive session for context recovery in the next session. However, it does not mention when not to use or suggest alternatives, leaving some ambiguity.

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