qa_session_append

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

No annotations are present, so the description must disclose behavior, but it only says 'Append one Q&A entry to session file.' There is no mention of whether existing data is preserved, what happens if the session file does not exist, required permissions, or return behavior. The one-question rule is a conversational convention, not a tool behavior disclosure.

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 only two short sentences, front-loaded with the main action 'Append one Q&A entry to session file.' Every word earns its place, and the one-question rule adds relevant constraint without redundancy.

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?

With four parameters, no annotations, and no output schema, this description is too thin. An agent would likely struggle to know what kind values map to, what understanding_pct means, or how session paths should be formatted. It is minimally viable but leaves critical gaps.

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%, and the description does not explain session_path, kind, content, or understanding_pct. The phrase 'Q&A entry' loosely hints that content relates to one of the kind enum values, but it does not map parameters to their purpose or explain the optional understanding_pct field.

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 appends a Q&A entry to a session file, which gives a specific verb and resource. It does not explicitly differentiate from siblings like qa_session_start, but 'append' and 'session file' make the core purpose understandable.

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 instruction 'Ask only ONE question per chat turn' provides some workflow guidance, but the description does not explicitly say when to use this tool versus alternatives like qa_session_start or estimate_context. Usage is mostly implied by the tool name and append semantics.

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