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

Annotations already cover the safety profile (readOnlyHint=false, destructiveHint=true, openWorldHint=false), so the bar is lower. The description adds one genuinely useful fact beyond them: toggling preserves the rule rather than removing it. It does not explain what disabling a rule affects, whether the change is immediate or reversible, or what permissions are required.

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?

A single efficiently front-loaded sentence with zero filler; the non-destructive constraint is the headline point. It is arguably too terse for the information it needs to carry, but nothing written is wasted.

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 simple two-required-parameter toggle with informative annotations and no output schema, the description is close to sufficient, but it omits parameter meaning and any error/permission context, leaving gaps that annotations do not fill.

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%, so the description carries the full burden and fails to mention either parameter. It never states that 'enabled' is the boolean target state or what form an 'automationId' takes (opaque ID from list/get calls), leaving an agent to infer semantics from bare property names.

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 gives a specific verb pair (turn on/off) and resource ('board rule'), and the clause 'without deleting it' implicitly separates it from delete_automation and create_automation in the sibling list. The only weakness is terminology drift between 'board rule' and the tool's own 'automation' naming, which could momentarily confuse an agent scanning for automation tools.

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 phrase 'without deleting it' hints that this is the non-destructive alternative to delete_automation, but the description never states when to toggle versus recreate a rule, nor what prerequisites (ownership, board access) are needed.

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