SaaS + seasoned — seasoned skills for builders, served with flavor.
A Claude Code plugin marketplace. The name is a pun: seasoned as in well-flavored and seasoned as in experienced — these are battle-tested skills from real building, not theory.
The first plugin is saasoned, a growth & go-to-market toolkit.
# 1. Add the marketplace (once)
/plugin marketplace add williancesar/saasoned
# 2. Install the plugin
/plugin install saasoned@saasonedThat's it. Restart isn't needed — the skills become available immediately.
A hub-and-spoke set of seven growth skills. Start at the hub — it routes you to the right one:
| Skill | What it owns |
|---|---|
saasoned:growth-foundations |
Hub / router. Worldview, shared vocabulary, and dispatch to the right skill below. |
saasoned:growth-traction-channels |
Pick the ONE distribution channel that moves the needle (Traction's 19 channels + Bullseye). |
saasoned:growth-positioning |
What is this, for whom, in what context (Obviously Awesome + Crossing the Chasm). |
saasoned:growth-habit-loops |
Retention via habit formation (Hooked's Hook Model + Fogg) with a mandatory ethics gate. |
saasoned:growth-customer-discovery |
Learn the truth from customers and build with an audience (The Mom Test + Embedded Entrepreneur). |
saasoned:growth-network-effects |
Cold-start and network/marketplace growth (The Cold Start Problem). |
saasoned:growth-experiments |
Turn any framework into a cheap, measurable test with a pre-stated kill condition. |
Claude invokes these automatically when relevant. You can also call one explicitly, e.g. "use saasoned:growth-positioning to sharpen my pitch."
Zero to One · Traction · Hooked · The Mom Test · Crossing the Chasm · Obviously Awesome · The Embedded Entrepreneur · The Cold Start Problem.
You don't need to memorize skill names. Describe your growth problem in plain language and Claude routes to the right skill (usually starting at the growth-foundations hub). Or name a skill explicitly when you know exactly what you want.
Let Claude route it (recommended):
> I built a SaaS for indie game devs but nobody signs up. Where do I even start?
> My landing page gets traffic but no conversions — is it a positioning problem?
> Users try the app once and never come back. Help me fix retention.
> I have an idea for a marketplace. How do I validate it before building?
> I'm about to spend $2k on ads. Is that the right channel for me?
Call a specific skill when you know what you need:
> Use saasoned:growth-positioning to sharpen the pitch for my dev-tools startup.
> Use saasoned:growth-traction-channels to rank channels for a B2B API product.
> Use saasoned:growth-customer-discovery to critique my user-interview questions.
> Use saasoned:growth-habit-loops to design an ethical engagement loop for a journaling app.
> Use saasoned:growth-network-effects to plan the cold-start for a local-services marketplace.
> Use saasoned:growth-experiments to turn "add referrals" into a cheap test with a kill condition.
What you get back: not generic advice, but a structured walk-through grounded in the source frameworks — e.g. a Bullseye channel ranking, a positioning statement filled out component by component, a Mom Test question rewrite, or an experiment spec with a pre-stated metric and kill condition. The growth-habit-loops skill always runs its output through an ethics gate before recommending anything.
A typical session flows hub → spoke → experiment:
> How do I grow my note-taking app? # → growth-foundations diagnoses & routes
> ...positioning first. # → growth-positioning sharpens the frame
> Now what's the cheapest way to test this? # → growth-experiments designs the test
