athena_prompt_hydrate

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'deterministically compile' and 'ancestry/digest,' which add some context, but it does not state whether the operation mutates state, what it returns, or any side effects. The behavior remains opaque for an agent deciding whether to invoke it.

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 with no filler or redundancy. It front-loads the main action ('Hydrate...') and preserves meaningful qualifiers like 'exact current' and 'deterministically.' Slightly more structure or examples could improve clarity, but it is appropriately compact.

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?

Without an output schema or annotations, and with four parameters whose semantics are mostly unexplained, the description is incomplete. The agent is left without information about return values, prerequisites, side effects, or how the addendum is used. The tool's jargon-heavy context demands more elaboration.

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?

Schema description coverage is 0%, so the description must compensate for the four parameters. It only hints that 'task/profile addendum' corresponds to the task and profile parameters, leaving include_text and previous_head completely unexplained. This is insufficient for proper parameter selection.

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 specific verbs ('hydrate', 'compile') and names the exact resource ('current Git prompt runtime') and output ('task/profile addendum with ancestry/digest'). This clearly distinguishes it from sibling tools like athena_hydrate or athena_frontier_hydrate by scoping to the Git prompt runtime and task/profile addendum.

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?

There is no explicit guidance about when to use this tool versus alternatives, no prerequisites, and no exclusions. The phrase 'exact current' implies a freshness requirement but does not explain when to choose this over athena_prompt_compile or rehydration tools.

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