What it does
Pmf Strategy is an agent skill from kostja94/marketing-skills. When the user wants to validate product-market fit, measure PMF, or plan before scaling. Also use when the user mentions "PMF," "product-market fit," "product market fit," "Sean Ellis test," "very disappointed," "vitamin vs painkiller," "PMF validation," "premature scaling," or "validate before scale." For GTM after validation, use gtm-strategy.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering Product strategy and Go-to-market strategy. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.
When your agent uses it
- Wants to validate product-market fit
- Plan before scaling
- The user mentions PMF
- Product-market fit
Example prompts
- “product-market fit,”
- “product market fit,”
- “Sean Ellis test,”
- “/pmf-strategy”
What it can do on your machine
Read from SKILL.md and the folder at commit 8dd89c5. 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
No URLs in SKILL.md.
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
Pmf Strategy loads about 1.2k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 527 words of instructions outside code blocks.
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.

Strategies: Product-Market Fit
Guides product-market fit (PMF) validation and measurement. PMF occurs when a product precisely meets market needs, creating widespread demand. ~99% of startups fail primarily due to PMF issues (vitamin problems, premature scaling). Use this skill when validating before scaling, measuring PMF, or diagnosing traction problems.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Definition
Product-market fit (Marc Andreessen): "Being in a good market with a product that can satisfy that market."
Signals: Customers buying rapidly; usage growing; word-of-mouth spreading organically; high retention, low churn.
Sean Ellis 40% Test
Question: "How would you feel if you could no longer use [product]?"
| Response | Meaning |
|---|---|
| Very disappointed | Strong PMF signal |
| Somewhat disappointed | — |
| Not disappointed | — |
| N/A – I no longer use | — |
Threshold: 40%+ answering "very disappointed" = PMF achieved. Below 40% = iterate.
| Score | Action |
|---|---|
| Below 25% | Significant changes needed |
| 25–39% | Close to PMF; iterate and improve |
| 40%+ | PMF achieved |
Best practice: Survey 40–50 active users (used product 2+ times in last 14 days). Segment by user type—some segments may have PMF while others don't.
Limitation: Combine with retention curves, engagement, organic growth; avoid false positives in early stages.
Vitamin vs Painkiller
| Type | Definition | Adoption |
|---|---|---|
| Painkiller | Solves urgent, acute problems; users actively seek solutions | Fast adoption; high retention; willing to pay |
| Vitamin | Nice-to-have; incremental benefit; users can live without | Slow adoption; expensive marketing to succeed |
~99% of failures: Solving vitamin problems instead of real pain. Validate: Would users be genuinely inconvenienced if your product vanished?
Validation: Talk to users; listen for frustration; run pre-sells; check frequency and time-sensitivity of the problem.
Key Indicators
| Indicator | Strong PMF |
|---|---|
| Retention | High; low churn |
| CAC vs CLTV | CAC decreasing relative to CLTV |
| Activation | Strong conversion to paying customers |
| Growth | Organic; word-of-mouth |
| NPS | High; enthusiastic advocacy |
Show full SKILL.md (207 more words)Show less
Common Failures
| Failure | Avoid |
|---|---|
| Vitamin problems | Solve urgent pain, not nice-to-have |
| Vanity feedback | Use retention data, not polite opinions |
| Premature scaling | Validate PMF before scaling acquisition |
| Misalignment | Customer-problem fit before product-build |
Product Research & SaaS Context
| Area | Notes |
|---|---|
| Product positioning | Target audience; core value; competitive differentiation |
| Market research | Competitor analysis; surveys; interviews to validate assumptions |
| SaaS form | Cloud delivery; subscription; ease of use; dependency on industry standardization |
| Enterprise / ACV | Customization; data security/private deployment; procurement cycles; buy vs SaaS trade-offs |
Use: When discussing PMF for SaaS or enterprise—factor in product research rigor and ACV-specific challenges. See gtm-strategy for enterprise GTM.
PMF as Continuous Process
PMF is increasingly a continuous validation—markets evolve; re-measure as you expand. Target "PMF for a niche" first (40%+ in one segment) before broadening.
Output Format
- PMF assessment (current signals, Sean Ellis score if available)
- Vitamin vs Painkiller diagnosis
- Validation approach (interviews, pre-sells, metrics)
- Next steps (iterate vs scale)
