map-assumptions SKILL.md skillA
map-assumptions from tomzx/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tomzx/agents/map-assumptions@git:20261007.b35fc4bPins git:20261007.b35fc4b in mdr.lock. Pin the fingerprint instead.

List the hypotheses, beliefs, and risks that must be true for an opportunity to succeed, ranked by leverage. Start of the PDLC Validate phase.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Map Assumptions
Validate begins by stating explicitly what is currently unstated.
For the opportunity that survived the Discover gate, enumerate everything that must be true for it to work, then rank by leverage (impact x uncertainty) so the next skill tests the few assumptions whose falsity would end the effort.
## Prerequisites
- Apply the shared PDLC conventions in `skills/pdlc/references/shared.md`.
- `opportunity-tree.md` with a `proceed` gate from Discover.
## Steps
1. Read the chosen opportunity and its candidate solutions from `opportunity-tree.md`.
2. Surface assumptions across four categories:
- **Desirability** — do they want this?
(problem real, willingness to adopt/pay)
- **Viability** — does it work for the business?
(pricing, unit economics, channel)
- **Feasibility** — can we build/operate it?
(tech, data, ops, partners)
- **Usability** — can they actually use it?
(workflow fit, effort)
3. For each assumption, record: the belief, why it matters, current confidence (low/med/high), and the evidence that would change your mind.
4. Rank by leverage = impact (if false, how bad) x uncertainty (how unsure).

How to install
mdr add tomzx/agents/map-assumptions@sha256:3a09f28080dcdbdfThe line at the top of this page pins the label git:20261007.b35fc4b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
