apply_automation_transaction

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

With no annotations, the description carries the full burden and does substantial work: it discloses the snapshot-before-mutation behavior, full rollback on any failure, and re-read verification of the restoration before reporting. It omits permission/auth requirements and the meaning of transaction_id, but the destructive-operation lifecycle is unusually well disclosed.

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, zero filler. The atomic scope is front-loaded and the rollback guarantee follows immediately, so the most decision-relevant information comes first.

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 destructive multi-write tool with no annotations and no output schema, the description covers the critical safety behavior (atomicity, snapshot, rollback, verification). It falls short on transaction_id semantics and any indication of what is returned on success, which an agent invoking a transaction tool would benefit from.

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 67% with three parameters. The description only refers generically to 'envelopes' and adds nothing about the writes item shape beyond what the schema sketch shows, and transaction_id is undocumented in both schema and description. Baseline 3 is appropriate since the schema does most of the work.

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 and resource: 'Atomically write several FX-parameter envelopes ... in one undo block.' The plural-plus-atomic framing implicitly separates it from the single-write siblings (write_automation, set_fx_param), but it never names an alternative explicitly, so the differentiation is left to inference.

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 mention of 'several ... e.g. a stereo pair' and 'one undo block' implies the batch/atomic case is the reason to pick this tool, but there is no explicit when-to-use or when-not-to-use statement and no named alternative such as write_automation for single envelopes.

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