Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00478 |
| Opus 5 | $0.00023 | $0.00239 |
| Sonnet 5 | $0.00009 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
catalog-commerce 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 11d ago.
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.
What it actually says
Catalog & Commerce
Doctrine
Commerce plumbing is unglamorous and decisive: dynamic product ads cannot run without a healthy catalog, and a catalog wired to a broken pixel just automates showing people the wrong products. Order matters: pixel first (see pixel-conversions), catalog second, product sets third. Product sets are angles for inventory: "best sellers", "under $50", "new arrivals" are different promises to different buyers.
When to use
- Ecom stores with enough SKUs that per-product creative is impractical.
- Before any retargeting play that shows people what they browsed.
- Needs a Meta Ads MCP with write access; creation steps are confirmed before running.
Run it
Catalog setup, step by step, confirm with me before each write:
1. List my existing catalogs and their product counts. If a catalog already exists, audit it instead of duplicating: how many products, how many rejected or missing images/prices?
2. Check the pixel link: is the catalog connected to my pixel, and are the product IDs in my purchase events matching catalog IDs? If not, stop and tell me; nothing downstream works until this does.
3. Propose 2-3 product sets that match my angles (for example: best sellers, entry-price items, the category my ads target). Show the filter logic.
4. On my approval, create the sets and tell me exactly which ad type they unlock (dynamic product ads, advantage+ catalog ads) and what a $20/day test on the best set would look like.
Guardrails
- Audit before create: duplicate catalogs are how accounts end up advertising stale prices.
- The pixel-to-catalog ID match is a hard gate. Skipping it produces ads for out-of-stock products at wrong prices.
- Product sets mirror angles: a set nobody wrote an angle for is inventory, not a campaign.
Good output looks like
One healthy catalog, 2-3 named product sets tied to angles, and a clear go/no-go on whether dynamic ads are ready to test.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

catalog-commerce is a skill published in the GitHub repository kelpi-ai/meta-ads-skills (3 stars, last pushed 2mo ago), licensed MIT. It adds 45 tokens to every session and 478 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
