GTM:OS — The GTM Operating System

Turn Claude Code into a full outbound campaign engine. Brief it. Build it. Ship it. Measure it.

GTM:OS is a Claude Code plugin that runs your entire go-to-market workflow — from ICP definition to list building, copy writing, shipping sequences, handling replies, and reporting on results. It connects to your outbound stack via API, enforces quality at every step, and never ships anything that drifts from the brief.

Built for: GTM engineers, SDRs, AEs, RevOps teams, agencies, and founders running B2B outbound.

Install

Prerequisites

You need Claude Code installed:

npm install -g @anthropic-ai/claude-code

Get started

git clone https://github.com/shyftai/GTMOS.git
cd GTMOS
claude

That's it. GTM:OS boots automatically — shows the banner, scans your connected tools, and asks which workspace to load. No config files to edit, no build step.

Note: After cloning, restart Claude Code (/exit then relaunch) for slash commands to become available. Claude Code loads commands at session start, so a freshly cloned repo's commands won't appear until the next session.

Connect your tools

GTM:OS works with your existing tools. Two ways to connect:

MCP servers (recommended) — Claude can use these tools directly with full capabilities:

Crispy — LinkedIn automation (78 tools)
Exa — semantic web search and company research
Firecrawl — web scraping and data extraction

Add MCP servers to your Claude Code settings — GTM:OS detects them automatically on boot.

API keys — add to .env for tools that connect via API:

cp .env.example .env
# add your keys (Apollo, Instantly, Attio, etc.)

You don't need all tools to start. GTM:OS works with whatever you have and tells you what's missing.

First run

When GTM:OS boots, run:

/gtm:onboard my-company

It asks your role (SDR, GTM Engineer, Head of Sales, Founder, or Agency), walks you through setup, and creates your workspace. Then you're ready to build campaigns.

Legal & Compliance

GTM:OS is a tool — not a compliance solution. You are responsible for how you use it.

Legal Disclaimer — warranty, liability, and indemnification terms
Acceptable Use Policy — what responsible use looks like
LICENSE — MIT License

GTM:OS includes built-in compliance helpers (suppression lists, regulation detection, consent tracking, hard gates before shipping) but these do not guarantee legal compliance. Consult legal counsel for your jurisdiction.

What it looks like

When you open GTM:OS in Claude Code, this is what you see.

Every task is checked against five sources of truth before anything ships:

File	What it controls
ICP.md	Who you target (company level)
PERSONA.md	Who you target (human level)
BRIEFING.md	Campaign angle, offer, CTA
TOV.md	Brand voice, channel rules, banned phrases
RULES.md	List quality standards, copy quality standards, lead scoring

If it drifts from the brief, it doesn't ship.

The campaign lifecycle

1. Onboard → /gtm:onboard walks through your offer, ICP, persona, voice, tools, and infrastructure. Have CRM data? Start with /gtm:deep-dive to build ICP from evidence.

2. Research → /gtm:research maps ICP companies, market landscape, and buying signals using Exa, Firecrawl, Ocean.io, and DiscoLike.

3. Build a list → /gtm:list-brief creates a sourcing brief, /gtm:enrich fills gaps via waterfall enrichment across Apollo, Icypeas, Prospeo, and more. /gtm:validate-list cleans, scores (0-100), and validates.

4. Write copy → /gtm:write drafts a sequence using cold email best practices — peer voice, observation-led openers, interest-based CTAs, angle rotation per touch. /gtm:write-multilang writes natively in 12 languages.

5. Ship → /gtm:ship runs a launch check (suppression, DNS, warmup, budget, holiday calendar, compliance) and pushes to Instantly, Lemlist, or Smartlead.

6. Manage → /gtm:replies classifies and drafts responses, /gtm:signals triggers timely outreach, /gtm:health monitors performance, /gtm:ab-test runs A/B tests with statistical significance tracking.

7. Report → /gtm:report generates client-facing reports, /gtm:debrief feeds learnings back into the system, /gtm:attribution connects pipeline revenue to campaigns.

Every tool is optional. Use what you have. GTM:OS reads tool availability from your .env and TOOLS.md, then adapts its workflows accordingly. Writes follow credit rules per workspace, and every write is logged in COSTS.md.

Any tool with an API works. The list above is the curated default set — not a hard limit. Add any tool to your TOOLS.md, drop the API key in .env, and GTM:OS will use it.

Key features

Waterfall enrichment

Cascading enrichment across multiple tools — email, phone, people, company. Cheapest sources first, skip tools you don't have, track hit rates to optimize order over time.

A/B testing

Set up, track, and resolve A/B tests on subject lines, openers, CTAs, body copy, and send times. Statistical significance rules (50+ sends with >20% diff, or 100+ with >10%). Winners auto-feed into snippet library and campaign defaults.

Deliverability copy guard

/gtm:spam-check (and an automatic pass inside /gtm:write and /gtm:validate-copy) scans every subject, body, and closeout line against a comprehensive banlist — promotional and phishing wording, em dashes, ALL CAPS, and silence-based "I'll stop if you don't reply" closeouts — and proposes a plain-language rewrite for every flag. A failed scan blocks the launch check.

List quality scorecard

/gtm:score-list grades a list A+ to F across 8 list-level dimensions — email verification coverage, duplicate emails, domain concentration, title relevance, bad-title detection, catch-all density, ICP fit, and name quality. Runs inside /gtm:validate-list and gates shipping: a list below C-grade doesn't ship. Complements the per-contact 0-100 lead score.

Positive reply scoring

/gtm:reply-score computes the metric that actually matters: positive reply rate (positive replies / total sent), not raw reply rate. Classifies every reply, reports against benchmarks (≥1% good, ≥2% great), flags hostile/unsub risk, and surfaces the positive replies that need a human response now.

Single-variable experiments

/gtm:experiment forces a clean test — one variable, locked constants, minimum sample size, and success criteria set before launch — so a result is actually attributable. Change list + copy + offer at once and you learn nothing; this is the antidote. Measured on positive reply rate at day 21.

Weekly operating rhythm

/gtm:rhythm is the operational cadence that separates hobbyists from top-1% operators: Monday deliverability audit, Wednesday positive-reply sweep, Friday retrospectives, biweekly inbox rotation, monthly spam-placement test, quarterly experiment review. Surfaces what's due now and links the command to run.

Lead source playbooks

Beyond firmographic search, /gtm:list-brief picks the right sourcing angle for the campaign: title-first, domain-first, local SMB via Google Maps, lookalike expansion, competitor-post engagers, or directory/list extraction — each with caching, cost-gating, and a path into validation.

Multi-language copy

Write sequences natively in 12 languages (French, German, Dutch, Spanish, Italian, Portuguese, Swedish, Danish, Norwegian, Finnish, Polish, and more). Per-language formality defaults, word limit adjustments, cultural norms. Not translation — native writing.

ROI attribution

Connect pipeline revenue to campaigns, channels, touches, personas, and signals. Four models: first touch, last touch, linear, time decay. Cost per reply, meeting, and deal.

ABM multi-threading

Reach 2-4 people at one company with role-appropriate messaging and coordinated timing. Buying committee mapping, staggered sends, cross-reference coordination. Optional ad warming via LinkedIn/Meta/Google Ads or HubSpot ABM.

Data hygiene

Monitor contact data freshness, re-verify emails older than 90 days, detect job changes via Apollo and Crispy, flag cold data, auto-suppress hard bounces. Data freshness score target: >80%.

Pipeline velocity

Track stage durations, detect bottlenecks (>30% stall rate), stalled deal alerts with suggested actions. Velocity formula and week-over-week trend tracking.

Website visitor identification

Identify companies (and people) visiting your website, cross-reference against ICP, and route high-intent visitors into signal-triggered campaigns. Supports Snitcher, RB2B, Warmly, and Leadinfo. Page intent scoring (pricing page = high, blog = low). Website visits sit at Tier 1 in the signal priority waterfall.

Daily briefing

/gtm:today scans everything and tells you what to do right now. Positive replies waiting? Ship a campaign? Signals to act on? Prioritized by urgency, adapted to your role.

Contact history

/gtm:contact shows every touchpoint with a person — campaigns they've been in, emails sent, replies, website visits, LinkedIn interactions, CRM deal stage. One unified timeline.

Competitor monitoring

/gtm:watch-competitors actively tracks competitor pricing pages, messaging, hiring patterns, and news using Exa and Firecrawl. Surfaces actionable signals — "Competitor X raised prices 61%" → triggers a displacement campaign suggestion.

Infrastructure provisioning

/gtm:provision stands up sending infrastructure from just your senders' LinkedIn URLs — suggests and reserves outbound domains, provisions inboxes with photos and DNS auth, attaches them to your sequencer, and starts warmup. Stage 1 produces a costed plan with no spend; you approve the domain shortlist and the spend, then walk away. Cloudflare (registrar + tracking domain), Zapmail/InboxKit (inboxes + DNS), Crispy (sender identity), Smartlead (warmup). Fresh inboxes, no pre-warmed.

Inbox health

/gtm:inbox-health monitors deliverability proactively — bounce rates per inbox, warmup status, domain reputation, DNS issues. Catches problems before they hurt campaigns.

Sequence templates

Save proven sequences as reusable templates (/gtm:save-template), browse the library (/gtm:templates), adapt them for new campaigns (/gtm:use-template), or import templates from files, URLs, or paste (/gtm:import-template). Templates carry performance data so you know what works.

Agency portfolio

/gtm:portfolio shows all workspaces at a glance — campaign status, reply rates, spend, and what needs attention across all clients. Cross-workspace learnings surface patterns that work everywhere.

Meeting prep & handoff

/gtm:prep-meeting generates a complete briefing sheet before a booked call — contact research, company intel, talking points, objection prep, discovery questions. /gtm:handoff creates a structured SDR → AE context transfer so prospects never repeat themselves.

Per-contact personalization

/gtm:personalize researches each contact individually and generates custom opening lines — LinkedIn activity, company news, job posts, website observations. Not merge fields. Real, researched insights at scale. Quality-rated per contact (★★★★★ to ★★☆☆☆).

Nurture track

/gtm:nurture manages warm leads on a timer. "Not now, maybe Q3" gets tracked with a follow-up date, trigger to watch, and warmth level. Auto-scans replies for nurture candidates. Cross-references with signal scan — when a nurtured contact's trigger fires, you know immediately.

Pipeline forecasting

/gtm:forecast predicts revenue based on weighted pipeline, active campaign conversion rates, and planned campaigns. Best/expected/worst case scenarios. Velocity-adjusted close dates. Risk flags for stalled deals and declining reply rates.

Warm intro detection

/gtm:warm-intro checks for mutual LinkedIn connections before cold outreach. Scans entire lists, categorizes contacts into warm intro / warm reference / cold tiers, and drafts intro requests. Warm intros convert 5-10x better.

Campaign cloning

Clone a successful campaign's structure, config, briefing, and A/B winners for a new segment or market. Cross-workspace cloning for agencies.

Compliance (optional)

Toggle privacy regulations on/off per workspace: CAN-SPAM, GDPR, CASL, CCPA/CPRA, PECR, LGPD, Australian Spam Act. Auto-detect from target geography or ignore entirely. All OFF by default.

Parallel processing (Swarm)

Spin up parallel agents for personalization, research, reply handling, list validation, and signal scanning at scale.

Smart defaults, full control

GTM:OS ships with sensible defaults for everything:

Copy: 2-4 word lowercase subjects, 75-word first touch, interest-based CTAs, banned spam words
Sending: 40 emails/inbox/day, 14-day warmup minimum, holiday blackouts for 20+ countries
Scoring: weighted 0-100 lead scoring (company fit, persona, signals, data quality, engagement)
Compliance: optional regulation toggles, suppression checks, unsubscribe on every email, bounce auto-removal

Every default is overridable per workspace. Add a ## Lead scoring overrides section to RULES.md, change copy rules in TOV.md, adjust sending limits in INFRASTRUCTURE.md. If you don't override, the defaults just work.

Workspaces

Each workspace is fully isolated — its own ICP, persona, briefing, voice, tools, costs, and pipeline. A workspace can be:

An agency client
A market segment
A product line
A geography
Any unit of GTM that deserves its own context

Notifications (optional)

Connect Slack to get real-time alerts:

Positive reply received
Meeting booked
Budget threshold crossed
Domain health red flag

Configure in COLLABORATION.md. Works via Slack MCP.

Team mode (optional)

By default GTM:OS runs in solo mode — all state lives in markdown, no database needed.

For teams, enable team mode with Supabase:

Create a Supabase project
Run supabase/migrations/001_initial_schema.sql
Add keys to .env
Run /gtm:collab setup

Adds: shared suppression lists, claim-based reply handling, live cost tracking, pipeline sync, approval audit trail, activity feed. Falls back to files automatically if Supabase is unreachable.
