meta_ads_campaigns_enable

Resume a paused Meta Ads campaign by setting its status to ACTIVE. Note that paused ad sets and ads do not auto-resume and must be enabled separately.

Instructions

Resumes a paused campaign by setting its status to ACTIVE. Ad sets and ads underneath retain their own status — if they are still PAUSED they do NOT auto-resume; call meta_ads_ad_sets_enable / meta_ads_ads_enable for those too. Returns the campaign id and new status. Reversible via rollback_apply or meta_ads_campaigns_pause.

TDQS

A4.4/5.0
Behavior4/5

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

With no annotations, the description carries the behavioral burden well: it discloses the status mutation, the important non-cascading effect on ad sets and ads, the returned values, and reversibility. It does not cover permission requirements, approval behavior, or failure modes, which are meaningful gaps for a mutation tool without annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is four tight sentences with no wasted language. The core action is front-loaded, followed by the critical child-object caveat, then return shape and reversibility.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a mutation tool with no annotations, rich schema coverage, and no output schema, the description covers the essential action, side-effect boundaries, return shape, and rollback path. It is slightly incomplete on auth/approval requirements and error behavior, but the schema handles approval and reason details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already explains all six parameters in detail. The description adds return-value context ('campaign id and new status') but does not add meaning beyond the schema for parameters such as campaign_id, approval, reason, expected, account_id, or decision_id.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Resumes a paused campaign by setting its status to ACTIVE.' It clearly distinguishes campaign-level activation from ad set and ad activation by warning that child objects do not auto-resume and naming the sibling tools to use for those.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit usage conditions: use this for a paused campaign, but separately call meta_ads_ad_sets_enable / meta_ads_ads_enable if child objects are still paused. It also names the undo alternatives: rollback_apply or meta_ads_campaigns_pause.

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