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

Annotations only declare readOnlyHint=false and destructiveHint=false, leaving the description to carry the semantics. It does so by disclosing the ordered state progression (implying a directional, non-destructive state transition) and an entry precondition (sufficient training episodes). It still omits whether the advance is one step or to a target level and behavior on failure.

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 compact sentences, front-loaded with the action and the state ladder, then the gating condition. 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 mutation tool with no output schema and fully-documented params, the description covers the action, the ordered states, and the precondition. The main residual gap is ambiguity about whether one call advances a single step or transitions to a chosen level, which matters for correct invocation.

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 100%, so fromNodeId and toNodeId are already documented. The description adds the concept of the automation ladder but never ties it to either parameter (no target-level parameter is mentioned), so it contributes only marginal meaning beyond the schema. Baseline 3 applies.

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?

Names a specific verb ('advance') and resource ('automation level for a transfer pair'), and enumerates the full state ladder (manual → ... → fully_autonomous), which strongly disambiguates it from neighbors like get_automation_status. It does not explicitly name or rule out any sibling, but the level ladder makes the operation's identity unmistakable.

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?

'Requires sufficient training episodes' is a genuine precondition, which implies when the call is appropriate. However, there is no guidance on when to use this versus get_automation_status or list_automation_status, and no statement of what happens if the precondition is unmet.

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