lc_preview_set_yara_source

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

The description only says 'Preview' which implies a dry-run, but no details about what the preview entails, what it returns, side effects, or required permissions. Without annotations, the description fails to disclose important behavioral traits.

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 one sentence, which is concise but at the expense of essential information. It is under-specified and does not earn its place as it lacks detail.

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 4 parameters, no output schema, and no annotations, the description is grossly insufficient. The agent cannot understand the tool's behavior or correctly invoke it without additional information.

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 mention any parameters. The agent receives no guidance on what parameters like oid, name, source, or token_ttl_seconds mean or how to use them.

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 the tool is for previewing creating or updating a YARA source. It clearly identifies the action (preview) and the resource (YARA source). However, it does not differentiate from other preview tools like lc_preview_set_yara_rule, but the resource is distinct.

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 on when to use this tool versus alternatives such as lc_get_yara_source or lc_list_yara_sources. There is no mention of prerequisites or context.

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