commit_write_session

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

No annotations are provided, so the description must disclose behavioral traits. It mentions 'atomic file replacement' but does not cover side effects, idempotency, permissions, or what happens if the session is invalid. This is insufficient for a commit operation.

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 a single sentence, which is concise and front-loaded. However, it could be slightly more informative without adding verbosity. Every word earns its place.

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 description is minimal but covers the core action. Given the presence of an output schema (not shown), return values are not required. However, it lacks context about prerequisites, error cases, or the relationship with sibling tools, leaving gaps for an AI agent.

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%, so the description must compensate. However, it provides no explanation for the 'session_id' parameter beyond its name. The parameter name is self-explanatory, but the description adds no additional meaning or 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 clearly states the action ('Commit') and the resource ('chunked write session'). It also emphasizes 'atomic file replacement', which distinguishes it from siblings like 'append_write_chunk' or 'abort_write_session'.

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 the tool is used after appending chunks to finalize a session, but it does not explicitly state when to use it or when alternatives (like abort) are more appropriate. No exclusions or context provided.

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