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.

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 5.5 | $0.00054 | $0.01096 |
| Sonnet 5.5 | $0.00027 | $0.00548 |
| Haiku 4.5 | $0.00013 | $0.00274 |
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 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.

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

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
httpxornodejs - You need GTM server-side container code (sGTM custom templates in JavaScript) — different domain; check
gtm-server-sideif 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.
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 VKirill/claude-lane-stack (124 stars, last pushed today), licensed MIT. It adds 134 tokens to every session and 2,740 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
