athena_frontier_ready

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does reveal that the tool 'persist only' a specific prerequisite and 'require explicit READY', implying it does not automatically mark the node ready. However, it omits critical behavioral traits such as side effects, error conditions, rehydration semantics, or whether current state is mutated. The description is too terse to provide adequate transparency for a state-changing operation.

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 dense sentence that front-loads the primary action ('Persist... then rehydrate...'). It is concise and avoids extraneous words. However, the extreme density and opaque jargon reduce readability, so it does not earn a perfect score.

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?

This is a complex tool with 13 parameters (7 required), no annotations, and no output schema. The description is a cryptic one-liner that does not explain the meaning of the expected_* digests, the rehydration process, the significance of 'require explicit READY', or what the tool returns. It is completely inadequate for an agent to invoke this tool with confidence, making it far from 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?

The schema description coverage is only 8% (only operation_at has a description). The tool description does not reference any parameter names, but it hints at the digest parameters via 'reducer-validated fixed-sequence' and at node_id via 'PENDING node'. This is insufficient for 13 parameters, especially the required expected_* digests. The description adds minimal meaning beyond the raw schema and does not compensate for the low 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 identifies a specific action: persisting a reducer-validated NODE_READY prerequisite for a pending node, then rehydrating and requiring explicit READY. This is a clear verb-resource combination, though heavy domain jargon (e.g., 'fixed-sequence NODE_READY prerequisite') makes it less accessible. It distinguishes itself from sibling frontier tools by focusing on the READY readiness state rather than claiming or hydrating.

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 phrase 'for one dependency-ready PENDING node' implies a specific usage context: a node that is pending and dependency-ready. This gives some guidance on when to invoke the tool, but there is no explicit mention of alternatives or when not to use it. The description does not reference sibling tools (e.g., athena_frontier_claim, athena_frontier_hydrate) as alternatives.

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