jio_duplicate_report

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions session-scoped state ('from this session') and a read-like operation ('Return'), but does not disclose what happens if no report exists, whether this is truly read-only, or if the report persists across tool calls within the session. This is insufficient for a tool with no annotation support.

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, focused sentence that delivers the essential information upfront with no filler or repetition. Every word contributes to understanding the tool's purpose.

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?

For a simple no-parameter tool, the description is serviceable but leaves gaps. It does not describe the content or format of the returned report, and it relies on the agent already knowing what a 'jio_find_duplicates report' is. Given there is no output schema and no annotations, the description should provide a bit more context about the report's structure or behavior when no report exists.

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?

The tool has zero parameters, so the baseline is 4. The description does not need to explain parameters since there are none, and no parameter information is missing.

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 uses a specific verb ('Return') and identifies a specific resource ('the last jio_find_duplicates report from this session'). This clearly distinguishes it from sibling tools like jio_find_duplicates (which generates the report) and jio_delete_duplicates (which acts on it).

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 phrase 'from this session' implies that this tool should be used after running jio_find_duplicates in the current session, but the description does not explicitly state when to use it, when not to use it, or mention any alternatives. Usage context is implied but not explicitly guided.

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