What it does

Product Market Fit is an agent skill from slgoodrich/agents. Frameworks for measuring, achieving, and maintaining product-market fit. Use when validating new products, assessing readiness to scale, diagnosing retention, or measuring PMF. Trigger on: 'do I have product-market fit', 'PMF survey', 'very disappointed score', 'retention curve analysis', 'ready to scale'.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files and assets (for example `assets/pmf-measurement-dashboard.md`, `assets/retention-curve-analysis.md` and `assets/sean-ellis-pmf-survey.md`).

It sits in Product & Project Management, covering Product strategy. The repository describes itself as: AI PM Workflows for Claude Code.

When your agent uses it

Validating new products
Assessing readiness to scale
Diagnosing retention
: do I have product-market fit

Example prompts

“do I have product-market fit”
“PMF survey”
“very disappointed score”
“/product-market-fit”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Market Understanding
Value Hypothesis
MVP Validation
PMF Measurement

What it can do on your machine

Read from SKILL.md and the folder at commit 3b5835b. 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

Product Market Fit loads about 3.1k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 82 tokens; SKILL.md has 1,443 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~82
When it runs · the whole SKILL.md, loaded when a task matches: ~3.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~22k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,443 words (~3,061 tokens).

“Frameworks for measuring, achieving, and maintaining the critical milestone where your product satisfies strong market demand.”
