Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00015 | $0.00471 |
| Opus 5 | $0.00008 | $0.00235 |
| Sonnet 5 | $0.00003 | $0.00094 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
workflow-foundation-to-design 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 11d 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 — 30 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run the end-to-end arc that pairs a Foundation Sprint (2 days of strategic alignment) with a Design Sprint (5 days of prototype validation) as one connected 7-8 day flow.
There is no bridge skill: canonical Knapp/Zeratsky methodology has no formal handoff move between the two sprints, and pm-skills does not invent one. The Founding Hypothesis from the Foundation Sprint is consumed directly as input context by the Design Sprint readiness and brief steps; the handoff is narrative only.
Workflow Steps
Step 1: Foundation Sprint (Days 1-2)
Run the full Foundation Sprint using the /workflow-foundation-sprint command (or follow skills/tool-foundation-sprint-readiness/SKILL.md through skills/tool-foundation-sprint-founding-hypothesis/SKILL.md in sequence). Output: a canonical Founding Hypothesis sentence plus an assumption scorecard.
Step 2: Narrative handoff
Carry the Founding Hypothesis and its highest-risk assumptions forward as the framing context for the Design Sprint. No intermediate artifact is required: the riskiest assumption on the scorecard typically becomes the Design Sprint's challenge and sprint questions. See docs/guides/using-foundation-sprint.md and docs/guides/using-design-sprint.md for the handoff narrative.
Step 3: Design Sprint (Days 3-8)
Run the full Design Sprint using the /workflow-design-sprint command (or follow skills/tool-design-sprint-readiness/SKILL.md through skills/tool-design-sprint-test-and-score/SKILL.md in sequence), seeding the readiness and brief steps with the Founding Hypothesis from Step 1. Output: the Decider's build / iterate / pivot / stop call grounded in five customer interviews.
Output
A strategic frame (Founding Hypothesis) validated or invalidated end-to-end by a tested prototype and a Decider's call, in one connected arc.
Reference the end-to-end workflow at _workflows/foundation-to-design.md for the full narrative, including the handoff guidance.

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.
- 11d ago First seen · 30 lines · 15 tokens per session scan A 50b9e1226305
workflow-foundation-to-design is a command published in the GitHub repository product-on-purpose/pm-skills (658 stars, last pushed today), licensed Apache-2.0. It adds 15 tokens to every session and 471 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
