athena_frontier_freshness

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

No annotations are provided, so the description must disclose safety and behavioral traits. It describes the comparison and outcome but doesn't state whether the tool is read-only, what it returns, how 'material' is determined, or any error/edge-case behavior. This leaves significant 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 a single concise sentence, front-loading the core action. However, its brevity sacrifices some clarity for an unfamiliar audience, though it remains efficient.

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?

For a tool with 8 parameters and no output schema, this description is too sparse. It fails to explain return values, the meaning of key terms, or how to interpret the result, making it incomplete for effective 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?

With 0% schema description coverage and 8 parameters, the description only indirectly maps to three expected digests (source_head, frontier_digest, prompt_stack_digest) and omits the other five parameters (task, fetch, remote, profile, source_ref). It provides no parameter-level guidance.

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 identifies a specific comparison operation across three named resources (shared source head, frontier digest, prompt-stack digest) and states a consequence. However, it doesn't explicitly distinguish from sibling tools like athena_prompt_freshness or athena_rehydration_verify.

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 implies that the tool is used to detect material coordinate changes that require rehydration, but it doesn't explicitly state when to use it versus other freshness/hydration tools, nor does it provide exclusions or prerequisites.

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