athena_topology_apply

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

With no annotations, the description carries the full burden and does well by disclosing transactional atomicity, the optimistic concurrency guard, and the recording of reversible before/after witnesses. It omits failure behavior on version mismatch or permission requirements, but it adds meaningful behavior beyond the schema.

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 core action and conditions. Every phrase adds value, with no filler or redundancy.

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 no output schema, no annotations, and a nested payload object, the description is compact but omits return value semantics and payload structure. It captures the core transactional behavior, making it usable for selection but not fully sufficient for correct invocation without additional schema hints.

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; it enumerates the valid operation values and explains expected_version's conditional role. However, it does not describe the payload's per-operation structure or the actor parameter, leaving a significant semantic gap.

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 the tool as transactionally applying specific topology mutation operations (INIT/REPLACE/FISSION/FUSE/PATCH_MODULE) to a collective topology, with a version-match guard. This distinguishes it from related sibling tools like athena_topology_get and athena_topology_rollback.

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 states a clear precondition: apply only when expected_version matches the current version, which is a strong usage signal. It does not explicitly name alternatives or exclusions, but the operational context is clear enough for tool selection.

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