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

The description adds substantial behavior beyond the annotations: openings found during the pause are NOT replayed, the first cycle after resuming is deliberately suppressed, and each alert retains its own is_active so individually paused alerts stay paused. These are exactly the non-obvious effects an agent could not derive from readOnlyHint/idempotentHint alone.

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?

Three short, dense sentences with no filler, and the most decision-relevant surprise (no replay of paused openings) is front-loaded after the effect statement. The misleading 'back off' phrasing in sentence one is the only structural weakness.

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?

With annotations covering the safety profile and an output schema handling return values, the description supplies the behavioral caveats it must. The remaining gap is routing: it never states that this is the account-wide counterpart to pause_all_alerts rather than resume_alert.

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?

The tool takes zero parameters, so the baseline is 4. There is no schema content for the description to enrich or duplicate, and it correctly says nothing about nonexistent inputs.

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 second clause states the concrete effect — 'its alerts are scanned again' — and the scope ('account's', 'every alert' in the title) distinguishes it from the single-alert sibling resume_alert. However, the lead sentence 'Turn the account's master switch back off' is confusingly worded for a resume operation and briefly reads as the opposite of the tool name, which costs it a 5.

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: an agent infers this is the counterpart to pause_all_alerts and that there must be a prior pause, but no sentence says when to choose this over resume_alert or pause_all_alerts. No prerequisites or exclusions are stated.

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