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

With no annotations, the description discloses the core state-changing behavior: it creates and signs a block, chains it, and consumes outstanding events. However, it does not disclose prerequisites (e.g., registered AIT) or potential failures, and it is silent on permissions or reversibility.

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 dense sentence with no fluff; it front-loads the action and packs in the profile name and chaining behavior. All words contribute meaning.

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 moderately complex but the description omits return behavior (no output schema) and usage timing (e.g., after witnessing events). It does convey the key state transition but leaves the agent without enough context to fully anticipate side effects or results.

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 only parameter `ait` is not described in the schema, and the description only references 'for an AIT' without explaining the expected format or identifier semantics. This is partial compensation for the 0% schema coverage but leaves room for ambiguity.

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 a specific action: rolls not-yet-blocked witness events into a signed block with the `period_summary` profile, chained to the prior block. It distinguishes the tool from siblings like `sigil_atap_witness` and `sigil_atap_register_ait` by naming the exact resource and process.

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?

No explicit usage guidance or alternatives are provided. The description implies the tool is used when there are pending witness events to consolidate, but it does not state when not to use it or direct the agent to sibling tools for related tasks.

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