working-backwards skillA

working-backwards is agent-read markdown (skill) from teambrilliant/dev-skills: Write an Amazon-style PR-FAQ (mock press release + FAQ) to pressure-test a product idea customer-first and kill weak ideas on paper. Use when someone says "write a PR-FAQ", "PRFAQ", "press release", "working backwards", "start from the customer", "draft the launch announcement", "is this idea clear enough to build", or has a fuzzy idea and wants clarity on what and why. NOT for testing risky assumptions with experiments (product-discovery) or build plans (shaping-work / write-plan)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.

What the file says

# Working Backwards

Start from the customer and the desired end-state, write it down, and iterate on
the *document* until the thinking is clear — long before any engineering. The
artifact is a **PR-FAQ**: a one-page mock press release + an FAQ of the hard
questions. Most PR-FAQs are never built — **killing a weak idea cheaply on paper
is the point, not a failure.**

Why writing: prose forces clarity that slides and good intentions can't. If you
can't write a compelling, honest press release for it, you don't understand it
yet — and neither will the customer.

References:
- `references/pr-faq-template.md` — the press-release + FAQ structure, section by section.
- `references/six-page-narrative.md` — the prose-memo / silent-read discipline (for proposals & reviews beyond a launch).
- `references/input-metrics.md` — input-vs-output metrics, DMAIC, the WBR (how you'd *measure* it once live).

## When to use this vs. its neighbors

- **product-thinker** decided *should we?* → use Working Backwards to force the *customer end-state* into focus.
- Idea is fuzzy / stakeholders disagree on what it even is → write the PR-FAQ; the draft surfaces the disagreement.

How to install

Latest version
mdr add teambrilliant/dev-skills/working-backwards@git:20260927.b9558d0
Exact content
mdr add teambrilliant/dev-skills/working-backwards@sha256:3b0e299a6decf856

Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
