### 📊 growth-hacker
Diagnose the real growth bottleneck and prescribe the next move, using the unified frameworks from three foundational growth books.
**What it does**: Synthesizes Ryan Holiday's *Growth Hacker Marketing*, Sean Ellis & Morgan Brown's *Hacking Growth*, and Weinberg & Mares' *Traction* into a single diagnostic + prescriptive system. Refuses to recommend tactics before diagnosing the stage — "founders pick the channel they're comfortable with, not the one their stage needs" is the #1 growth mistake.
**Use when**:
- Stuck at a revenue plateau and not sure why
- Choosing between marketing channels
- Diagnosing a leaky funnel (low conversion, low activation, low retention)
- Searching for product-market fit
- Designing a viral loop or referral program
- Picking a North Star metric or growth equation
- Running a weekly growth-experiment cycle (ICE scoring)
**Knowledge includes**:
- 4-level diagnostic model (PMF → Aha → Channel → Optimization)
- Sean Ellis 40% test (with the 5 companion questions verbatim)
- Aha-moment thresholds from Facebook, Twitter, Slack, Dropbox, Uber, Instagram, eBay
- The Growth Equation (Inman, eBay, Amazon examples)
- Activation playbook (HubSpot Sidekick's 11→12 experiments, Etsy, Tinder)
- Retention playbook (smile graph, cohort analysis, three phases)
- Engineered virality (Holiday's principles + viral math K = i × c)
- The full 19-channel Bullseye taxonomy with $1k test design per channel
- Weekly growth cycle + ICE scoring (verbatim Ellis methodology)
- Mindset quotes from Holiday, Andreessen, Thiel, Ellis, Andrew Chen
**Size**: ~80 KB (SKILL.md + 9 reference files + 19 channel deep-dives)

### 💼 ultimate-sales
Master sales coaching skill synthesizing six foundational books into a single working system.
**What it does**: Distills *SPIN Selling* (Rackham), *Fanatical Prospecting* (Blount), *Gap Selling* (Keenan), *The Challenger Sale* (Dixon & Adamson), *Never Split the Difference* (Voss), and *How to Win Friends & Influence People* (Carnegie) into a stage-aware sales coach. Diagnoses where you are in the journey first, then prescribes the right move from the right book — most sales failures come from using a small-sale tactic in a big-sale context, pitching before diagnosing, or arguing instead of asking.
**Use when**:
- Drafting cold emails, DMs, follow-ups, or any outbound outreach
- Preparing for or reviewing discovery calls, demos, or QBRs
- Handling pricing pushback, objections, or stalled deals
- Negotiating contracts, terms, or salary
- Planning ICP, messaging architecture, channel sequencing, or pipeline math
- Coaching reps or being coached
- Reviewing your own sales messaging
**Knowledge includes**:
- The diagnose-first sales loop (5-question pre-flight check before any tactic)
- SPIN question arsenal (Situation / Problem / Implication / Need-payoff) with example banks
- Gap Selling Problem Identification Chart (PIC) for pre-call planning
- Challenger 6-step Commercial Teaching choreography (Warmer → Reframe → Rational Drowning → Emotional Impact → New Way → Solution)
- Voss tactical empathy toolkit (mirroring, labeling, accusation audit, calibrated questions, Ackerman bargaining model, "no"-oriented framing)
- Blount prospecting playbook (30-Day Rule, Golden Hours, 5-step phone framework, voicemail framework, RBO turnarounds, combo prospecting)
- Carnegie influence principles cross-walked to modern sales (where Carnegie holds, where modern research overrides)
- 12+ verbatim email templates (cold outbound, follow-up, re-engagement, pricing, internal)
- 20+ verbatim phone scripts and objection turnarounds
- Voss one-page negotiation prep template
- Full extracts of all six books (~4,200 lines) for deep reference
**Size**: ~280 KB (SKILL.md + 6 frameworks + 3 asset packs + 6 book extracts)

### ✍️ galloway-storytelling
Rewrite any writing to be more engaging using Scott Galloway's (Prof G) storytelling playbook.
**What it does**: Sharpens flat, dry, or forgettable writing into punchy, story-driven prose using a small set of named, teachable moves — the Wow Test, Data Elevation, the Hook, Assume Intimacy, More Drama, and Zoom Out. Edits by cutting and elevating, not by adding words, and hands back both the rewrite and a short rationale naming which moves were applied.
**Use when**:
- A newsletter, LinkedIn/X post, or build-in-public update feels flat
- A draft opens with throat-clearing or buries its best line
- Big numbers land as abstractions ("$320B is huge") instead of feelings
- A pitch, cold email, launch announcement, or landing-page copy needs punch
- You want to learn the craft, not just get an edit — each rewrite names the technique
**Knowledge includes**:
- The six core Galloway moves, each with a rule, a why, and worked examples
- The four Data Elevation yardsticks (time, size, familiar object, baseline)
- The six Hook types and a warm-up detector for buried ledes
- The Assume Intimacy "kill list" of hedges and filler
- An extended reference: the Crocs Test, Anchored Provocation, Vulnerability, Visualization, with Galloway's exact quotes and sources
**Size**: ~15 KB (SKILL.md + 1 reference file)
