What it does

Building Communication Engine is an agent skill from GTM-Strategist/gtm-strategist-skills. Use this skill when the user wants to choose marketing channels, plan their launch newsletter, set a GTM budget, collect social proof, or build their communication strategy. Phase 8 of 12: interactive guided workflow for choosing GTM motions, narrowing channels, projecting funnels, drafting social posts, launching newsletters, collecting social proof, marketplace strategy, GTM budget, and launch plan presentation.

Example prompts

  • “/building-communication-engine”

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. GTM motions and actions selected based on stage and resources
  2. 2-3 channels chosen with evidence your ICP is there
  3. A funnel model to test and iterate on
  4. Social content ready for pre-launch credibility
  5. Newsletter or update mechanism for supporters
  6. 5+ social proof statements for conversion
  7. Marketplace strategy (or deliberate skip)
  8. Realistic budget mapping spend to returns
  9. Launch plan with owners, timelines, and metrics

What it can do on your machine

Read from SKILL.md and the folder at commit a5ead26. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • gtmstrategist.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Building Communication Engine loads about 2.8k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 1,390 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use this skill when the user wants to choose marketing channels, plan their launch newsletter, set a GTM budget, collect social proof, or build their communication strategy. Phase 8 of 12: interactive guided workflow for choosing GTM motions, narrowing channels, projecting funnels, drafting social posts, launching newsletters, collecting social proof, marketplace strategy, GTM budget, and launch plan presentation.

Phase 8: Building Your GTM Communication Engine

This is Phase 8 of the GTM Strategist methodology. You have your product defined, pricing set, positioning crafted, and launch assets prepared. Now you build the engine that gets your message to market.

This phase answers: How will we reach our market, through which channels, with what budget, and who owns what?


Before Starting

Read my-gtm-context.md first. Key sections: Target Market (2), ICP (3), Team & Resources (8), Goals (9), Voice (10).

Check outputs/ for prior phase work. This phase builds on:

  • outputs/01-*.md — OPE canvas, value prop, 90-day plan (Phase 1)
  • outputs/03-*.md — Validated ICP/ECP personas (Phase 3)
  • outputs/05-*.md — Pricing strategy and business model (Phase 5)
  • outputs/06-*.md — Positioning, UVP/USP, messaging (Phase 6)
  • outputs/07-*.md — Website, demo, media kit, pitch deck (Phase 7)

If key prior outputs are missing, tell the user which phase to complete first and why.


Task 1: Choose GTM Actions & Understand GTM Motions

Output file: outputs/08-gtm-motions.md Duration: 1-3 hours

Map the five core GTM motions and choose which fit your stage and resources.

The Five GTM Motions: Inbound (content/SEO pulls prospects to you), Outbound (direct outreach), Product-Led/PLG (free trial/freemium), Community-Led (build audience first), Partner-Led (leverage others' audiences).

For each motion, score 1-5 on: ICP Fit, Resource Match, Time to Results, Scalability, Stage Fit.

Stage-based defaults:

  • Pre-launch → Community-Led + Outbound (build audience before product)
  • Just launched → Outbound + Inbound (direct outreach for fastest feedback)
  • Post-launch → Inbound + PLG (content compounds; product sells itself)
  • Scaling → All five based on channel data

Within each motion, pick specific actions. Do not try everything — pick 3-5 total actions across motions. Deliver: selected motions (ranked with scores), selected GTM actions (with owner, timeline, success metric), motions deprioritized (and why), key assumptions to validate.


Task 2: Narrow Down Channels

Output file: outputs/08-channel-selection.md Duration: 1-3 hours

Pick 2-3 channels maximum. Better to dominate one channel than be mediocre on five.

For each candidate channel, evaluate: ICP Presence (are they actually there?), Content-Market Fit, Competition Density, Cost to Play, Measurability, Compounding potential.

Quick channel guide:

  • LinkedIn (B2B): 3-5 posts/week, personal > company page, 2-4 months to traction
  • Email/Newsletter: Weekly minimum, value-first 80/20, 1-3 months to engaged list
  • SEO/Content: 2-4 articles/week, 4-8 months (slow compound, high ceiling)
  • Product Hunt: One-shot event, needs 50+ supporters, immediate spike then decay
  • Paid Ads: Immediate results, expensive without optimization, needs known conversion rates

Deliver: 2-3 selected channels (with evidence, cadence, owner, 90-day goal, monthly cost), channels deprioritized, month-by-month sequencing plan.


Task 3: Project Your Funnel

Output file: outputs/08-funnel-projection.md Duration: 1-3 hours

Model your funnel from top to bottom. Work backward from revenue goal.

Backward funnel math: Start with revenue goal → divide by average deal size → customers needed → divide by close rate → opportunities needed → continue up through SQLs, MQLs, leads, visitors. Use industry benchmarks as starting assumptions (B2B SaaS: 2-5% visitor-to-lead, 20-30% opp-to-customer; B2C: 1-3% visitor-to-lead, 2-5% trial-to-customer).

Break down the funnel per selected channel. Model three scenarios (conservative at half benchmark, base at benchmark, optimistic at +30%).

Deliver: revenue target, backward funnel model, per-channel breakdown, sensitivity analysis (3 scenarios), key levers to optimize, assumptions and risks.


Task 4: Draft 5+ Social Media Posts

Output file: outputs/08-social-media-drafts.md Duration: 1-3 hours

Pre-launch content for your personal profile so you don't look like a ghost when prospects check. The goal is NOT to sell — establish credibility and signal something is coming.

Five post categories: Expertise Signal ("I've spent X months studying..."), Behind the Scenes ("Building [product] taught me..."), Problem Spotlight ("Every [ICP] I talk to has the same complaint..."), Insight/Hot Take ("[Common belief] is wrong..."), Social Proof Tease ("Just finished our 10th interview...").

Write from personal experience. Use specific numbers and stories. Hook in first line. End with engagement prompt (question, not CTA). Match platform native style. Reference voice from my-gtm-context.md Section 10.

Deliver: 5+ full post drafts (each with category, platform, timing relative to launch), plus a publishing calendar.


Task 5: Launch Newsletter / Updates

Output file: outputs/08-newsletter-plan.md Duration: 1-3 hours

Start a newsletter or closed updates channel for stakeholders, early adopters, and supporters.

Options: Email newsletter (Beehiiv, ConvertKit, Substack), Closed blog/updates page, Private community updates (Discord/Slack), LinkedIn newsletter.

Content mix per issue: Progress update (2-3 paragraphs), Insight or learning (3-5 paragraphs), One specific ask or CTA (1-2 sentences).

First 4 issues: #1 The Why (origin story + problem validation), #2 The How (approach + what's different), #3 The Proof (early signals, interview snippets), #4 The Launch (details + exclusive early access).

Deliver: strategy (format, tool, frequency, target list size), audience building plan (how to get first 100 subscribers), content calendar for 4 issues, full draft of Issue #1, metrics to track (open rate >40%, click >5%, reply >2%).


Task 6: Collect Social Proof (5+ Statements)

Output file: outputs/08-social-proof-collection.md Duration: 1-3 days

Social proof is the single strongest conversion lever. Collect at least 5 statements before launch.

Strength hierarchy: Named customer + metric (strongest) → Named customer + quote → Logo wall → Anonymous quote → Aggregate stat → Advisor endorsement → Self-reported metric (weakest).

Who to ask: Interview participants who showed positive sentiment (Phase 2-3), alpha/beta testers, design partners, advisors, industry peers who saw your demo.

How to ask: Short message referencing the specific positive thing they said. Offer three options: named quote, anonymous quote, or they write their own version.

Enhancement: Turn vague quotes into specific ones (always get approval). "It's really good" → "This is the first tool that actually fits how our team works."

Deliver: 5+ statements (each with exact quote, attribution, context, permission status, best use case), social proof gaps, outreach plan for more.

Task 7: External Marketplace Strategy

Output file: outputs/08-marketplace-strategy.md Duration: 1-3 hours

Decide which launch platforms (if any) to use and plan timing.

Key platforms: Product Hunt (tech early adopters, one-shot), AppSumo (deal seekers, post-launch), Indie Hackers (bootstrappers, build in public), G2/Capterra (B2B buyers, needs 10+ reviews), Hacker News (developers, unpredictable), Reddit (varies by subreddit, anti-promotional).

Launch on marketplace if: ICP is active there (validated), 50+ supporters, clear demo-able "aha moment", can handle traffic spike. Skip if: Enterprise ICP, needs hands-on onboarding, no support network, product not ready for scrutiny.

Deliver: decision (which platforms or skip), for each selected platform: why, timeline, goal, prep checklist, support network plan.


Task 8: GTM Budget

Output file: outputs/08-gtm-budget.md Duration: 1-3 hours

Build a realistic GTM budget mapping spend to channels and expected returns.

Budget categories: Tools & Subscriptions ($100-500/mo), Content Creation ($0-2K/mo), Paid Advertising ($0-5K/mo start small), Events & Community ($0-1K/mo), Partnerships (performance-based), PR & Outreach ($0-2K one-time), Time Cost (founder hours at opportunity cost — usually the biggest line).

Per-channel ROI: For each channel, estimate: monthly spend, time investment (hours x opportunity cost), expected leads/month, expected customers/month, CAC, LTV:CAC ratio (target >3:1), payback period.

Deliver: Q1 budget summary (cash + time), detailed month-by-month budget table, per-channel ROI projections, budget rules (max % on unproven channels, review cadence), what's NOT budgeted and why.


Task 9: Present Launch Plan to Team

Output file: outputs/08-launch-plan-presentation.md Duration: 1-3 hours

Compile everything from Tasks 1-8 plus prior phase outputs into a single launch plan for team buy-in.

Structure: The Opportunity (problem, why now, target customer — from Phases 1-3), Our Approach (motions, channels, funnel — Tasks 1-3), Launch Assets & Readiness (from Phase 7 + Tasks 4-7), Budget & Resources (Task 8), Timeline & Owners (week-by-week for 4-8 weeks with RACI matrix), Success Metrics (30/60/90-day targets).

Include a launch readiness checklist covering all prior deliverables. Include risks with likelihood, impact, and mitigation. Include specific decisions needed (who decides, by when).

Deliver: complete launch plan document with executive summary, all sections, RACI matrix, timeline, readiness checklist, risks, and decisions needed.


Summary

Phase 8 transforms your positioning and assets into an operational engine. You should now have:

  1. GTM motions and actions selected based on stage and resources
  2. 2-3 channels chosen with evidence your ICP is there
  3. A funnel model to test and iterate on
  4. Social content ready for pre-launch credibility
  5. Newsletter or update mechanism for supporters
  6. 5+ social proof statements for conversion
  7. Marketplace strategy (or deliberate skip)
  8. Realistic budget mapping spend to returns
  9. Launch plan with owners, timelines, and metrics

Next phase: Phase 9 (Executing Launch) — pulling the trigger on everything planned here.

  • Channel specifics: Phase 11 (Running Marketing) covers each channel in detail
  • Outbound sequences: Phase 12 (Executing Sales) for cold outreach and prospecting
  • Funnel optimization: Revisit Task 3 with real data once you have traffic flowing
  • Budget rebalancing: Review monthly — kill what doesn't work, double down on what does
