meta_ads_ad_sets_pause

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

Discloses that ads under the ad set stop serving even if they are ACTIVE, describes the reversible nature, and mentions it is lightweight. With no annotations provided, this level of detail is valuable, though it could mention rate limits or auth requirements.

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 description is compact with three sentences, each serving a purpose: action, impact, and additional notes. Properly front-loaded with the verb and outcome.

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 pause action with no output schema, the description adequately covers the return value (ad_set_id and new status) and side effects (does not affect siblings). However, it could clarify if the ad set status change is immediate or has any delay.

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 100% and already describes each parameter well (account_id with fallback to config, ad_set_id required). The description adds minimal additional insight, only restating the parameters' roles. Baseline 3 is appropriate.

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 clearly states the action (pauses a single ad set), the mechanism (setting status to PAUSED), and distinguishes it from sibling tools like meta_ads_ad_sets_enable and meta_ads_ads_pause, which serve different purposes.

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?

Explicitly mentions when to use (pausing a single ad set), provides alternatives for reversal (rollback_apply or meta_ads_ad_sets_enable), and clarifies that it does not affect sibling ad sets, aiding in correct tool selection.

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