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 | $0.02158 |
| Opus 5 | $0.00032 | $0.01079 |
| Sonnet 5 | $0.00013 | $0.00432 |
| Haiku 4.5 | $0.00006 | $0.00216 |
Grade A, and why
google-tag-manager 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 8d 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.

Google Tag Manager
Expert-level guidance for Google Tag Manager — auditing containers, designing tag and trigger architecture, debugging firing issues, implementing consent mode v2, and advising on server-side tagging.
Install
git clone https://github.com/thatrebeccarae/claude-marketing.git && cp -r claude-marketing/skills/google-tag-manager ~/.claude/skills/
Core Capabilities
Container Auditing and Optimization
Full container audit covering the six core areas: overview stats, tag inventory, trigger review, variable audit, folder organization, and naming convention assessment. Identifies unused tags, duplicate GA4 config tags, over-broad triggers on conversion tags, undefined variable paths, and consent mode gaps. Produces prioritized recommendations ranked by impact and effort.
Tag Architecture
Expert guidance on all common tag types:
- GA4 Configuration (
gaawc) — one per domain, holds measurement ID (always via constant variable), enhanced conversions settings, and shared config. All GA4 event tags must reference this as their Configuration Tag. - GA4 Event (
gaawe) — fires individual events with parameters sourced from data layer variables. References thegaawcconfig tag. - Google Ads Conversion Tracking — conversion ID + label, value and currency from data layer, deduplication tag ID for enhanced conversions.
- Google Ads Remarketing — conversion ID, custom parameters for audience building.
- Meta Pixel — base code + standard events (PageView, ViewContent, AddToCart, InitiateCheckout, Purchase). Use community template from Template Gallery rather than custom HTML.
- Custom HTML — unsandboxed JavaScript, creates CSP risk. Only use when no Template Gallery alternative exists.
- Community Templates — vetted third-party templates for Cookiebot, OneTrust, HotJar, Meta Pixel, LinkedIn Insight Tag, and more. Always prefer over Custom HTML.
Trigger Design
Matching triggers to tags with correct scoping is the single biggest factor in data quality. See REFERENCE.md for the full trigger type taxonomy. Key principles:
What ships with it
3 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.

google-tag-manager is a skill published in the GitHub repository thatrebeccarae/claude-marketing (137 stars, last pushed 4mo ago), licensed MIT. It adds 63 tokens to every session and 2,158 once invoked, about $0.0003 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 2026-09-03.
