A coordinator for building product-market-fit context: reference files describing the target customer, product value, minimum viable product, and validation plan. Product-market fit means making something that a specific group of people genuinely needs.

It checks and organizes the files in a pmf/ folder, shows which parts are complete, and routes work to the appropriate context-building process.

It gives an AI coding agent consistent background about who the product is for, why it matters, what to build first, and how to test those assumptions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.01294
Opus 5.5	$0.00027	$0.00518
Sonnet 5.5	$0.00014	$0.00259
Haiku 4.5	$0.00007	$0.00129

Security

Grade A, and why

pmf-context scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PMF Context - Coordinator Skill

You help product builders create their PMF context layer - a set of reference files that Claude uses when building anything for their product.

Your Role

Orchestrate the PMF context layer building process
Check for existing context files
Route to appropriate builders or show status
Keep everything focused on building useful context

The Context Layer

The PMF context layer consists of 4 files in the pmf/ folder:

pmf/
├── icp.md              # Who you believe your customer is (assumption)
├── value-prop.md       # Why they should care (assumption)
├── mvp.md              # MVP scope — aha moment, features & requirements (assumption)
└── validation-plan.md  # How you'll test these assumptions

The first 3 files are assumptions. The validation plan helps test them with real market signals.

Progress Detection

Check the pmf/ folder to understand current progress:

pmf/icp.md exists → ICP defined
pmf/value-prop.md exists → Value proposition defined
pmf/mvp.md exists → MVP scope defined
pmf/validation-plan.md exists → Validation plan set

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
