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 | $0.00158 | $0.15367 |
| Opus 5.5 | $0.00063 | $0.06147 |
| Sonnet 5.5 | $0.00032 | $0.03073 |
| Haiku 4.5 | $0.00016 | $0.01537 |
Grade A, and why
meta-ads-audit 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 1,427 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adapted from the GoMarble Paid Media Claude Skills repository (https://github.com/gomarble-ai/gomarble-ai-paid-media-claude-skills) by its author, shared under GoMarble's attribution license. Works with any data source: a connected ads MCP such as GoMarble, CSV exports, screenshots, or pasted tables.
A consolidated set of skills for analyzing and optimizing Meta Ads (Facebook + Instagram) accounts. These skills are framework-agnostic - the analytical logic (Pareto, Hook/Hold scenarios, decision matrices, guardrails) applies regardless of where the data comes from.
The skills define what to know, what data to look for, how to interpret it, and how to recommend action. They do not depend on any specific tool integration.
Read-and-recommend only. These skills never make changes to the user's Meta Ads account. Claude reads data and produces recommendations in plain language; the user applies the recommended changes themselves in Meta Ads Manager.
Data Sources Are Not All Equal
Data can come from four kinds of sources, but they have very different completeness. Some skill rules silently break on weaker sources. Always identify the source first and consult the Data Source Compatibility Matrix below before applying any rule.
| Priority | Source | Notes |
|---|---|---|
| 1 (preferred) | A connected MCP server exposing Meta Ads data (e.g. GoMarble, Meta official) | Returns raw API fields, action arrays, full targeting, breakdowns. All rules work. |
| 2 | A CSV/Excel export from Ads Manager | Most rules work, but a few are inert - see compatibility matrix. Several signals require separate exports (breakdowns, video metrics, ad-level vs ad-set-level views). |
| 3 (narrow questions only) | Screenshots of report tables | Use only for spot questions on metrics that are visibly captured in the screenshot. Skip deep analysis. |
| 4 (last resort) | Direct copy-paste of metric values | Treat as user-asserted; ask for the underlying export when stakes are real. |
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.

meta-ads-audit is a skill published in the GitHub repository swan-gtm/gtm-skills (221 stars, last pushed 8d ago), licensed MIT. It adds 158 tokens to every session and 15,367 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-09-11.
