Build the right GTM tool stack for any stage — solo founder ($100/mo), small team ($500/mo), growth team ($2K/mo), and enterprise ($10K+/mo). With cost breakdowns, tool comparisons, and stack architecture. Use when choosing GTM tools, building a tech stack, comparing platforms, or optimizing tool spend. Triggers on: "tool stack", "tech stack", "GTM tools", "which tool", "compare tools", "tool budget", "stack for my stage", or any tool selection request.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Tool Selection & Stack Builder ## Overview Choosing GTM tools is the most expensive decision most teams make — not because tools are expensive, but because the wrong stack wastes months of productivity. This skill builds stage-appropriate tool stacks with cost breakdowns and clear rationale for every choice. **Automation strategy:** Load `references/gtm-automation-expert-playbook.md` (Jen Igartua) for maturity assessment before adding tools. Clay = enrichment; n8n = orchestration; Cargo category = persistent routing at scale — see playbook decision matrix. ## Authoritative Foundations - **Jen Igartua (Go Nimbly) — Stack layering** — Layer the stack as must-have basics, performance boosters, and delighters; don't buy boosters before basics work. - **Jesse Ouellette — Lean stack** — Start with the fewest tools that run the process, and add a tool only when a stable process is bottlenecked. - **Eric Nowoslawski — Agency stack** — Cold email infra at scale — 2 inboxes/domain, backup inboxes, Creative Ideas testing. - **HubSpot Academy — CRM automation** — Lifecycle stages, object model, and workflow enrollment patterns. ## When to Use - "What tools do I need for cold email?" …

How to install
mdr add leadmagic/gtm-skills/tool-selection-stack@sha256:c1bc220c4197ec56The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
