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

With no annotations, the description carries the burden of behavioral disclosure. It reveals the auth requirement and the side effect of updating parent run summaries, which is additional context. However, it does not disclose whether the operation is reversible, what the response looks like, or other potential side effects.

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 two sentences, front-loaded with the core purpose and followed by the authentication requirement. Every word contributes, with no redundancy or filler.

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 tool's complexity (7 params, no annotations, no output schema), the description is far too sparse. It does not explain return values, expected outcomes, the meaning of 'Younanix checkpoint/query,' or the exact nature of the parent run summary updates, making it insufficient for reliable use.

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?

There are 7 parameters with 0% schema description coverage, and the description adds no parameter-specific meaning. Terms like trigger_reason, access_path, lesson_ids, and plan_impact are entirely unexplained, leaving the agent unable to construct valid arguments.

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 records a Younanix checkpoint/query during a Hermes task run and updates parent run summaries. This is a specific verb-plus-resource with a clear effect, though it does not explicitly differentiate from sibling recording tools like record_reflection or record_subagent_trace.

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 only mentions the prerequisite of x-agent-key and task ownership, but provides no guidance on when to use this tool versus alternatives. It lacks any comparative context or scenarios where this tool is preferred over similar recording tools.

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