What is google-tag-manager?

A guide for controlling Google Tag Manager through its API. Google Tag Manager is a service for managing website or app tracking tags, triggers, and variables without editing each page directly.

Use it to list or change containers, workspaces, tags, triggers, and variables; publish or roll back versions; clone workspaces; and diagnose failed API requests.

It gives a defined process for publishing, rolling back, copying, and auditing tracking configurations, including handling concurrent edits and API errors.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/VKirill/claude-lane-stack

npx agentmods add skills/vkirill/claude-lane-stack/google-tag-manager

Made for: Claude Code.

Or install lane-stack, the plugin that ships this one along with the rest of its 53 skills, 4 commands, 17 agents, 1 hook.

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	$0.00134	$0.02740
Opus 5	$0.00067	$0.01370
Sonnet 5	$0.00027	$0.00548
Haiku 4.5	$0.00013	$0.00274

Security

Grade A, and why

google-tag-manager scanned grade A 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🎯 Version Requirements (June 2026)

Primary pins:

GTM API: v2 (stable)
googleapis (Node): 144.x
google-api-python-client: 2.x
Node.js: 24.x (Active LTS)
Python: 3.14.x

Usage

Loaded automatically when its description matches the active task. This is the single source of truth for Google Tag Manager API v2 operations: reading container state, making writes, publishing versions, and rolling back. Read the section you need, then follow the link to the relevant reference file for full detail.

Use this skill when

Listing, creating, or updating GTM containers, workspaces, tags, triggers, or variables programmatically
Publishing a workspace to live — requires the two-step create_version + publish flow
Rolling back a GTM container to a previous version (two-step: create_version_from_old → publish)
Auditing all tags in a container: list tags referencing a specific variable, find unused triggers
Bulk-renaming or migrating variables via export-edit-import pattern
Cloning a workspace for staging / QA before publish
Diagnosing etag conflicts (409) on concurrent container edits
Managing write quota (~25 write ops/min/container) and planning batch operations
Setting up a service account or OAuth flow for GTM API access
Finding account IDs and container IDs via API (accounts.list, containers.list)

Do not use this skill when

You need GA4 event analytics (sessions, conversions, reports) — use google-analytics
You need Google OAuth / Service Account credential setup — use google-cloud-auth
You need to write data into GA4 via Measurement Protocol — use google-analytics
You need Yandex.Metrica tag management — different provider; load yandex-metrica
You need generic HTTP transport patterns (retries, backoff) — use httpx or nodejs
You need GTM server-side container code (sGTM custom templates in JavaScript) — different domain; check gtm-server-side if that skill exists

What ships with it

8 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.

Changes

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.
