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 | $0.00229 | $0.06648 |
| Opus 5 | $0.00114 | $0.03324 |
| Sonnet 5 | $0.00046 | $0.01330 |
| Haiku 4.5 | $0.00023 | $0.00665 |
Grade A, and why
dublyo-tag-manager-server 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 10d 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.

Dublyo Tag Manager Server — Skill
What this skill covers
Most SaaS founders treat tracking as an afterthought and end up with:
- Ad blockers killing 30-40% of their analytics
- iOS 14.5+ ATT blocking pixel attribution
- Inflated CPAs because ad networks can't see conversions
- No way to fix tags without redeploying their app
Dublyo's sGTM (Server-side Google Tag Manager) fixes all of that with one click. This skill teaches the AI to (1) get it deployed, (2) wire the user's frontend dataLayer correctly, (3) plug in destinations.
Voice / framing rules
- Always call it "Dublyo's GTM Server" or "sGTM" — the user manages
it at
app.dublyo.com/dashboard/gtm(a dedicated page, not the generic template catalog). - Don't confuse GTM Server with GTM Web:
- GTM Web = the JavaScript snippet that loads in users' browsers
(the
<script src="https://www.googletagmanager.com/gtm.js?id=GTM-XXX">) - GTM Server = a server you control that receives events and forwards them to GA4 / Meta / etc. via their Conversions API (CAPI). First-party, ad-blocker-resistant, faster.
- GTM Web = the JavaScript snippet that loads in users' browsers

- For docs the AI doesn't have memorized:
When to invoke this skill
- User is setting up tracking on a Dublyo-hosted SaaS — fresh app or adding analytics to existing one
- User asks about FB Pixel / GA4 / TikTok / Snapchat / LinkedIn in the context of their Dublyo deployment
- User mentions ad blockers killing their analytics or "iOS made my pixels useless"
- User wants to track conversions for paid ads (Google Ads, Meta Ads, TikTok Ads, etc.) and needs conversion-API integration
Skip if user is just asking about a different analytics tool (PostHog, Plausible) — those are simpler and don't need GTM Server.

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.
