What is meta-ad-builder?

A controlled workflow for researching, building, and deploying finished ads to Meta, the company behind Facebook and Instagram, through its Marketing API.

It helps choose destinations, optionally create campaign structure, upload images or videos, add text variations, deploy paused ads, change their status, research competitor ads, and review performance data.

It reduces the risk of sending an ad live by using dry runs, recording where creatives came from, and creating campaigns and ads as paused until activation is separately confirmed.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00099	$0.03217
Opus 5	$0.00049	$0.01608
Sonnet 5	$0.00020	$0.00643
Haiku 4.5	$0.00010	$0.00322

Security

Grade A, and why

meta-ad-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 16 executable files (scripts/check-meta-env.sh, scripts/create-campaign-structure.py, scripts/deploy-ad.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Meta ad builder

Turn a finished creative into a Meta ad through this controlled sequence:

research → copy → destination selection → structure (optional) → dry run → PAUSED deploy → separate explicit activation → performance-loop handoff

No creation command in this skill has an ACTIVE option. Deployment creates PAUSED ads. Activation is a separate command with a stronger confirmation gate.

When to use this skill

Trigger on phrases like:

"deploy this video to Meta" / "publish this as a Facebook ad"
"build/launch a Meta ad" / "push this creative into "
"create a Meta ad with this image and copy"
"create a paused campaign/ad set" / "show my Meta destinations"
"activate/pause/archive this Meta ad, ad set, or campaign"
"pull my top-performing ads" / "what are my best ads by ROAS"
"research competitor ads" / "pull 's ads from the Ad Library"

Do not use this skill to generate creative — that's pixar-style-ad, claymation-ad, generate-youtube-thumbnail, uni1-image-ad, etc. This skill owns direct Meta Marketing API research, structure, deployment, and gated status changes. It does not write to Airtable or another creative database.

Read order

This file — workflow, decision tree, safety rules.
Invoke human-ad-copy, then read prompting/copy-guide.md for the copy.json handoff.
reference/deploy-patterns.md — creative spec, upload, lineage, structure, and retry mechanics.
reference/meta-api-cheatsheet.md — the full Meta Marketing API reference (campaigns, ad sets, ads, enums, gotchas, Ad Library). Consult as needed; don't read end-to-end.

Prerequisites

Env (in .env — see your repo's .env.example):
- META_ACCESS_TOKEN (required) — long-lived token with ads_management scope
- META_AD_ACCOUNT_ID (required) — with or without the act_ prefix
- META_PAGE_ID, META_IG_USER_ID, META_PIXEL_ID (optional defaults for deploy)
- META_API_VERSION (optional, default v23.0)
Python deps: python3 -m pip install -r shared/skills/meta-ad-builder/scripts/requirements.txt
A target ad set. Select an existing one, or explicitly create PAUSED structure with create-campaign-structure.py.
The finished creative on disk — an image or video file path. Chat-pasted files are not accessible; ask the user for a real path.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
