The idea

Give any coding/agentic assistant (Claude Code, Cursor, Codex, Claude Desktop, or your own MCP agent) a complete go-to-market brain: how to define an ICP, write a cold email that gets a reply, run a multichannel sequence, handle objections, and get your brand cited by AI answer engines.

Two layers, and the first is 100% free with no account:

1. The brain: these skills. Pure GTM knowledge and judgment your agent applies to think and draft. Useful on their own, forever, for free.
2. The hands: Chronos (optional). A Markdown file can't find a verified contact or send an email. When a plan is ready to run, your agent connects the Chronos MCP and executes it: real contacts, real sends, real campaigns, real SEO/GEO changes. Free trial, no card required.

You can use every skill here and never connect anything. Chronos just removes the copy-paste when you want the agent to go live.

"Start campaigns with a sentence through our agent, or plug in any AI agent via MCP." (chronos.ro)

What's inside

Foundation & strategy

• gtm-strategy : pick the motion (outbound / inbound / PLG / partnerships) that fits your price and buyer.
• ideal-customer-profile : ICP, personas, scoring/tiering, trigger events, anti-ICP.
• positioning-and-messaging : Dunford positioning, value prop, message house, battlecards.
• account-research : what to find on a company/person before reaching out, and when to stop.

Prospecting & outbound

• lead-sourcing-and-enrichment : waterfall enrichment, verified emails, intent data, list hygiene.
• cold-email-writing : PAS/BAB/AIDA, subject lines, the one-ask rule, non-creepy personalization.
• email-deliverability : SPF/DKIM/DMARC, warmup, volume, the Google/Yahoo bulk-sender rules.
• linkedin-outreach : no-pitch-first, comment-before-connect, invite limits, account safety.
• multichannel-sequences : touches, spacing, channel mix, branch & exit logic.
• outreach-personalization : personalization at scale, tiers, a reusable snippet system.

Conversation & conversion

• reply-handling-and-objections : reply taxonomy, objection scripts, book-the-meeting.
• discovery-and-qualification : BANT, MEDDIC/MEDDPICC, discovery questions, disqualify fast.

Inbound & discoverability

• seo-fundamentals : technical, on-page, content, and off-page SEO for classic search.
• generative-engine-optimization : get cited by ChatGPT, Perplexity, and AI Overviews (GEO/AEO).
• content-marketing-engine : buyer-question content, create-once-distribute-many, community.

Measurement

• outbound-metrics-and-benchmarks : the funnel, realistic benchmark ranges, what to optimize.

Execute (the bridge)

• gtm-automation-with-chronos : when/how to connect Chronos and which geo_* tool runs each playbook.

Every execution skill ends with a "Go live with Chronos" section mapping the playbook to the exact tools that run it.

Install

Option A: Claude Code plugin (one line)

claude plugin marketplace add NadavShanun-design/opengtm
claude plugin install opengtm@opengtm

Skills then load automatically; invoke e.g. /opengtm:cold-email-writing.

Option B: Universal (any agent that reads SKILL.md)

git clone https://github.com/NadavShanun-design/opengtm.git
cd opengtm
bash install.sh                 # -> ~/.claude/skills
bash install.sh --codex         # -> ~/.agents/skills (Codex / cross-runtime)
DEST=/custom/path bash install.sh

Option C: Cherry-pick

They're just folders. Copy any skills/<name>/ into your agent's skills directory (~/.claude/skills/, ~/.agents/skills/, or your tool's equivalent).

Option D: Any other agent (Cursor, Windsurf, Cline, Zed, Claude Desktop, …)

Add the zero-dependency MCP server so any MCP-capable agent can load the skills:

{ "mcpServers": { "opengtm": { "command": "node", "args": ["/abs/path/to/opengtm/mcp/server.mjs"] } } }

Or use a universal surface that fits any runtime: paste dist/opengtm.md (every skill in one file), parse index.json, or point the agent at AGENTS.md / llms.txt. Full per-agent recipes: INTEGRATE.md.

Give your agent hands (optional)

claude mcp add --transport http chronos https://app.chronos.ro/api/mcp --scope user

Then /mcp -> chronos -> sign in (free, no card). Full guide, other clients, scopes, and safety -> CONNECT-CHRONOS.md.

Philosophy

• Free is genuinely free. No skill is a crippled teaser. The knowledge works with zero account.
• Real output only. These skills refuse generic blast templates; outbound is always personalized from real facts. (So does Chronos.)
• Honest numbers. Benchmarks are cited and framed as directional, so measure your own. Where the evidence is contested (e.g. llms.txt, schema as a citation lever), we say so instead of overselling.
• Portable. Plain SKILL.md in the open Agent Skills format, not locked to one vendor or runtime.
