plc_commit_changes

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

Beyond the annotations, the description discloses two meaningful behavioral traits: the commit produces a local revision only, and it neither applies changes to Sysmac Studio nor compiles PLC code. That prevents an agent from assuming the IDE project is updated. It does not state what happens on an invalid or already-consumed transaction_id, which keeps it from a 5.

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 short sentences, the action stated first and the critical non-effect second. Every clause carries information and nothing is padded.

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?

An output schema exists, so return values need not be explained, and the non-destructive scope is covered. What is missing for a transaction-based commit tool is the lifecycle context: how the transaction id is obtained, whether the commit is final or repeatable (annotations say non-idempotent), and what failure modes to expect.

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% and the single parameter (transaction_id) is never mentioned in the description. The agent gets no hint about where the transaction id comes from, its format, or whether it is consumed by the commit. The description therefore fails to compensate for the schema 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?

States a specific verb and resource: 'Commit staging to a new local revision.' That is a clear, non-tautological action an agent can distinguish from generic writes. It does not name a sibling tool, so it stops short of full sibling differentiation.

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?

Usage is only implied: the word 'staging' suggests this runs after changes are staged, and the second sentence clarifies what the call does NOT do (apply in Sysmac Studio, compile). No explicit alternative is named, so an agent must infer whether plc_preview_changes or plc_begin_transaction is the prerequisite step.

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