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

With no annotations, the description carries the full burden but does disclose meaningful behavior: runs are scored on prohibited effects, a pass yields a signed promotion receipt, and pricing/cost model is given. It omits failure behavior, side effects on the clone, and auth/plan prerequisites beyond cost, so it is only partially transparent.

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?

Two tight sentences with the purpose front-loaded ahead of the commercial detail. The pricing clause is useful but slightly dilutes focus; nothing is redundant.

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?

No annotations, no output schema, and zero parameter documentation for a 5-param tool. The description covers outcome and cost but leaves the agent without enough to invoke it correctly, particularly on mirror_id/agent/actions semantics.

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 coverage is 0% and five parameters (mirror_id, agent, actions, variant, task_class) are completely undocumented in both schema and description. The words 'workflow' and 'clone' offer only the faintest mapping to actions/mirror_id, leaving the agent to guess formats and meanings.

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?

States a specific verb+resource ('Rehearse a workflow against the clone') and describes the outcome ('scored on prohibited effects; a pass earns a signed promotion receipt'). It loosely ties to siblings via 'clone' (create_mirror) and 'receipt' (verify_receipt) but never names or contrasts them explicitly.

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 when-to-use, when-not, or alternative guidance. The pricing sentence implies a pre-promotion rehearsal step, but the agent gets no signal on how this relates to drift_check or verify_receipt, which is exactly where routing guidance is needed.

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