analyze_payload_noise

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

With no annotations, the description carries the full burden. It discloses the method (uses MD5 hashes) and the goal (identify repeated payloads that may represent noise). It does not mention side effects, but as an analysis tool this is likely read-only, so the description provides adequate transparency.

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 succinct and front-loaded with the core purpose. It follows a clear structure: summary, method, args, returns, with no filler content.

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 output schema exists and sibling tools like open_can_log and get_session_info provide session context, the description is mostly complete. It could mention that a session must already be open, but the session_id parameter adequately implies this.

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 description coverage is 0%, so the description must compensate. It explains min_repetitions well ('Minimum number of repetitions to consider as noise') and notes the default of 10. However, session_id is only described as 'Session identifier', lacking context on how to obtain or use it, which leaves a gap.

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 'Analyze CAN bus payload repetition to detect noise in logs', which is a specific verb (analyze) and resource (payload repetition). This distinguishes it from sibling tools like query_can_messages and scan_payload_for_value, which focus on querying or scanning specific values.

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 use when analyzing CAN logs for noise, and the mention of 'noise' sets it apart from alternatives. However, it does not explicitly state when not to use this tool or name alternative tools, so exclusions are missing.

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