nt_list_topics_offline

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

No annotations exist, so the description must carry the full behavioral burden. The description only says 'list unique topic names,' providing no insight into side effects, permissions, performance implications, or what 'filtered' entails. It fails to disclose any behavioral characteristics beyond the most basic function.

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 one concise, single sentence with no filler. It is appropriately brief for the function it describes, though this brevity comes at the cost of completeness.

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?

Despite having an output schema and five parameters, the description is severely underpowered. It doesn't explain what a 'recording' is, how filters work, what the output schema contains, or how this offline tool differs from its online counterpart. The lack of any supplementary information makes it impossible for an agent to use this tool correctly.

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?

With 0% schema description coverage and no parameter documentation in the description, this tool offers no additional meaning beyond the parameter names (regex, prefix, wildcard, etc.). The description's 'optionally filtered' is too vague to clarify how parameters work or interact.

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 lists unique topic names from a recording and can be filtered. It uses a specific verb and resource. However, it doesn't explicitly distinguish itself from the sibling tool nt_list_topics, though the 'offline' in the name provides some differentiation.

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?

There is no guidance on when to use this tool versus alternatives like nt_list_topics or nt_subscribe_offline. The phrase 'optionally filtered' is the only hint, but no explicit context, examples, or exclusions are provided. It fails to help the agent choose between this and related tools.

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