builder-growth

Skills and agents that enforce quality across the full growth lifecycle:

Strategy → Channel Selection → Offer → Campaign → Launch → Metrics → Funnel → Experiment → Retention → Messaging Review

Growth strategy defined before channels are chosen, channels chosen before campaigns are built, offers validated before copy is written, copy that clears the "who cares?" test, launches planned with rollback criteria, metrics named before execution, funnels diagnosed before they are optimised, experiments designed with stopping rules before they run, retention loops defined before launch, pricing and social proof reviewed before they ship, and AI capability claims reviewed for accuracy before they ship.

→ Visual overview

Works standalone or alongside A Team, builder-ai, builder-design, and builder-product.

Skills

Not every skill is required on every project — use the ones that match the work in front of you. See CLAUDE.md for the full trigger sequence.

Skill	What It Enforces
growth-strategy-design	Growth stage, segment, goal, constraint, channel hypothesis, offer, north star, and 90-day hypothesis defined before execution
channel-selection-audit	Every candidate channel scored against 8 criteria before a campaign is built
offer-quality-gate	Target customer, problem, outcome, mechanism, proof, risk reversal, pricing, CTA, and objections defined before copy is written
positioning-audit	Clear category, specific audience, and differentiated claim before any copy is written
campaign-brief-generator	Objective, audience, offer, message, channel, creative specs, and success metric defined before execution
copy-quality-gate	"So what?", "who cares?", and "why now?" tests before any copy ships
launch-plan-design	Launch goal, timeline, task ownership, success metrics, and rollback criteria defined before launch day
growth-metrics-design	North star, input/output metrics, leading/lagging indicators, and metric owners defined before execution
funnel-analysis	Leak identified and root-caused before any optimisation begins
experiment-design	Hypothesis, metric, sample size, duration, stopping rule, decision rule before any test runs
retention-design	Activation moment, habit loop, and reactivation path defined before launch
social-proof-review	Every testimonial, logo, case study, and quantified result sourced and permissioned before publication
pricing-page-review	Pricing clarity, tier differentiation, risk reversal, and disclosed limitations before a pricing page ships
ai-messaging-review	AI capability claims reviewed for source, scope, and accuracy — no unsourced quantified claims

The builder-* Ecosystem

Pack	Domain	Skills	Agents
A Team	Engineering baseline	19	26
builder-ai	LLM engineering	8	5
builder-design	AI UI design	8	5
builder-product	Product quality	7	3
