set_transport_recording_context

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

Annotations already declare readOnlyHint=false and destructiveHint=false. The description adds the behavioral trait 'guarded' and 'plan or apply', hinting at a two-phase workflow, but it does not explicitly describe that a dry run returns a plan and application requires a confirmation token. It is a useful hint but not a full disclosure.

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 entire description is one short, front-loaded sentence. 'Plan or apply' captures the dual mode, and 'guarded' signals a safety workflow. There is no filler, and every word earns its place.

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 complex, guarded mutation tool with 8 parameters, nested objects, and no output schema, the description is far too brief. It never mentions the required expectedStateVersion, the dry-run/confirm-token workflow that the schema hints at, or what a plan response contains. The agent would have to infer most of the operational context from the schema alone.

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 high (75%), and the schema already explains dryRun, confirmationToken, expectedStateVersion, and the nested record/overdub fields individually. The description contributes only the general notion of playhead and recording-mode changes, which does add high-level meaning but does not compensate for the un-described parameters.

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 names specific verbs ('plan or apply') and a specific resource ('guarded playhead and recording-mode changes'), so an agent can tell this tool is about recording-mode and playhead changes with a safety mechanism. It does not explicitly contrast with sibling tools like set_transport_context, so it is clear but not fully differentiated.

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 guidance on when to use this tool versus alternatives such as set_transport_context or get_transport_recording_context. The description implies a dry-run/apply workflow but never states conditions like 'use for safe, reversible changes' or 'when you need a confirmation token.'

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