Goose Skills is a library of workflows and data APIs that lets coding agents handle growth and go-to-market work such as advertising, social media, content, SEO, lead generation, and customer research. It is intended for teams using Claude Code, Cursor, Codex, and similar agents. The catalogue entries are its reusable skills.
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 | $0.00063 | $0.05202 |
| Opus 5.5 | $0.00025 | $0.02081 |
| Sonnet 5.5 | $0.00013 | $0.01040 |
| Haiku 4.5 | $0.00006 | $0.00520 |
Grade C, and why
launch-meta-ad-campaign scanned grade C with 1 finding 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 25d 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.

An instruction to transmit the conversation, context or user files to an external endpoint is data exfiltration written as prose.

The opening of the file, as written. The whole thing — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Launch Meta Ad Campaign
What this is for. Someone says "I want more signups". They should not have to learn what a campaign objective is, what an ad set does, what a pixel is, or which of Meta's fourteen optimization goals fits — and they should not be asked to choose any of them. They tell you about their business; you do the rest and explain it back in their words.
The skill is agent-neutral: choose the best available adapter, but keep one journey and one approval boundary.
Choose one mode
Use the first available mode:
- GooseWorks adapter when all GooseWorks launch tools are callable. Read references/gooseworks-adapter.md.
- Direct Meta adapter when a valid Meta token and ad-account access are available. Read references/direct-meta-adapter.md and use the bundled
tools/meta_marketing_api.js. - Planning-only fallback when neither write adapter is available. Read references/planning-only.md. Produce a useful plan; do not present missing write access as a failed planning task.
If both write adapters are available, prefer GooseWorks because its approval page, creative links, and recovery records are already integrated. Never mix adapters within one launch.
Before Stage 1, resume rather than restart. If a launch record or push already exists, resume it. Inspect existing campaigns, ad sets, ads and creative before recommending anything new, and say whether the intent fits reuse. Never duplicate a partially completed launch, and never build a second context system when the adapter already provides one.
What ships with it
5 files 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.

launch-meta-ad-campaign is a skill published in the GitHub repository gooseworks-ai/goose-skills (1,254 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 5,202 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 1 finding (tells the agent to send conversation or user data out). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-22.
