athena_cycle_replay

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

With no annotations, the description must disclose behavioral traits itself. It adds a valuable caveat that re-simulation is not performed, suggesting a read-only verification operation. However, it omits side effects, error semantics, and what constitutes a successful or failed verification, leaving gaps.

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 efficient at two sentences with no redundant content. The first sentence packs in substantial technical detail, which may be dense but each term contributes to specifying the tool's function. The second sentence adds a critical limitation without extending length unnecessarily.

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 (RAG/HUG-packet/GAP/FIELD/AOR/transport child runs) and lack of an output schema, the description is too terse. It does not explain what the verification returns, how results should be interpreted, or what failure looks like. An agent would struggle to act on the tool's output without additional context, making completeness inadequate.

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 sole parameter 'cycle_id' has no schema description (0% coverage) and is not explained in the tool description. While the description references 'cycle state', it does not clarify how to obtain a cycle_id, what format it should take, or any constraints beyond the schema's minLength. The description fails to compensate for the low schema coverage.

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 ('Verify') targeting concrete resources ('stored cycle state digest', 'deterministic replay/integrity receipts' of persisted child runs). It clearly distinguishes itself from sibling replay tools by explicitly stating that external semantic execution is not re-simulated, making its scope precise.

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 an explicit when-not condition ('External semantic execution/test truth is not re-simulated') but no direct when-to-use guidance or named alternatives. It implies use for checking stored integrity, but does not compare with related tools like athena_cycle_state or athena_transport_replay, leaving some ambiguity.

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