workflow-foundation-sprint

workflow-foundation-sprint is a command for Claude Code from product-on-purpose/pm-skills. It costs 19 tokens per session (690 once invoked), scanned A, original, Apache-2.0.

A structured two-day workshop for turning uncertain early product beliefs into one testable founding hypothesis and a list of assumptions to check. It is a product-discovery workshop, not an agile or Scrum sprint.

In plain words
What is it for?
Use it to assess readiness, prepare the workshop, define the customer and opportunity, and produce a founding hypothesis with an assumption scorecard.
Why use it?
It gives an early-stage team a defined process for clarifying its target customer, product idea, and evidence needs. This helps separate assumptions that need testing from decisions that are already supported.

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.

Security

Grade A, and why

workflow-foundation-sprint 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run the Foundation Sprint, a structured two-day workshop (Knapp/Zeratsky) that converts fuzzy early-stage product beliefs into a single, testable Founding Hypothesis plus an assumption scorecard.

This workflow chains the 7 tool-foundation-sprint-* skills in their canonical sequence, with tool-note-and-vote invoked at decision moments throughout. For each step, read the skill instructions and follow them to produce the artifact.

Note: Foundation Sprint is a workshop methodology, NOT an agile / Scrum sprint. For pm-skills' agile sprint planning, use /workflow-sprint-planning.

Workflow Steps

Step 1: Readiness

Use the tool-foundation-sprint-readiness skill from skills/tool-foundation-sprint-readiness/SKILL.md to diagnose whether the team should run a Foundation Sprint now, postpone, or do prerequisite work first.

Step 2: Brief

Use the tool-foundation-sprint-brief skill from skills/tool-foundation-sprint-brief/SKILL.md to lock scope, team, logistics, and success criteria before Day 1.

Step 3: Basics (Day 1 morning)

Use the tool-foundation-sprint-basics skill from skills/tool-foundation-sprint-basics/SKILL.md to produce the target customer, important problem, team advantage, and competitor map as one coherent strategic frame.

Step 4: Differentiation (Day 1 afternoon)

Use the tool-foundation-sprint-differentiation skill from skills/tool-foundation-sprint-differentiation/SKILL.md to produce scored differentiators, a 2x2 chart, decision principles, and a Mini Manifesto.

Step 5: Approach Options (Day 2 morning)

Use the tool-foundation-sprint-approach-options skill from skills/tool-foundation-sprint-approach-options/SKILL.md to generate 3-7 candidate approaches as one-page summaries for Magic Lenses evaluation.

Step 6: Magic Lenses (Day 2 afternoon)

Use the tool-foundation-sprint-magic-lenses skill from skills/tool-foundation-sprint-magic-lenses/SKILL.md to evaluate the approaches through the 4 classic plus at least 1 custom lens, then name the top bet and a backup.

What this file has done since we first saw it

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.
