ti_indicators_misp

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

With no annotations provided, the description carries the full burden of behavioral disclosure. "Fetch" reasonably implies a read-only retrieval operation with no mutation, which is useful. However, it does not disclose anything about failure behavior, access requirements, or whether it returns raw file content or a reference, leaving some behavioral uncertainty.

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, front-loaded sentence with no unnecessary words. It clearly communicates the core purpose and the distinguishing MISP-format detail without any filler, which is ideal for a simple tool.

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 tool is simple, and the output schema is present, so return values do not need to be explained in the description. However, the description does not clarify how this tool relates to sibling indicator tools, and with no annotations it misses an opportunity to provide richer operational context such as prerequisites or expected file-size limits. It is adequate but not complete.

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 100%, so the parameters year and file_name are already fully documented in the input schema. The description adds no additional meaning about how these parameters are used or formatted. This meets the baseline of 3 but does not exceed it.

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 states a specific verb and resource: "Fetch a MISP-format indicator file from the Threat Intelligence feed." It is clear that this tool retrieves a file in MISP format, which distinguishes it from sibling indicator tools like ti_indicators and ti_indicators_paged. However, it does not explicitly contrast those siblings, so it falls just short of full 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?

The description provides no guidance about when to choose this tool over alternatives such as ti_indicators or ti_indicators_paged. There is no mention of conditions, exclusions, or fallback tools. The MISP-format wording implies a use case, but the agent is left to infer the decision criteria.

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