assumption-mapper — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited assumption-mapper (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Every product bet rests on a stack of assumptions. This skill makes them explicit, classifies each as Known / Believed / Hoped, and produces a ranked test plan so the team validates the riskiest assumptions before committing to build.
The assumptions you don't write down are the ones that kill the product. Hidden assumptions become "obvious in hindsight" only because no one stress-tested them. The mapper's job is to drag them into the open and force a verdict on each.
| Tier | Definition | Action |
|---|---|---|
| Known | Direct evidence, multiple independent sources, recent data | No test needed; document the evidence link |
| Believed | Reasonable inference from indirect or partial evidence | Test if assumption is critical; defer if not |
| Hoped | Wishful thinking dressed as reasoning; no real evidence | Test before any meaningful investment |
Cross with criticality (Critical / High / Medium / Low) → the Critical × Hoped quadrant is the team's actual risk surface.
The mapper walks through 5 categories to surface assumptions a one-shot brainstorm misses:
| Category | Example Assumptions |
|---|---|
| Customer / Demand | "SMB ops leaders feel this pain weekly"; "buyers will pay $X" |
| Solution / Product | "Our approach is materially better than the workaround"; "the model can hit 90% accuracy on this task" |
| Channel / Distribution | "We can acquire this segment via content"; "our sales team can sell this without retraining" |
| Economic / Unit | "CAC stays under $X at this segment"; "support cost scales sublinearly" |
| Competitive / Time | "Incumbents won't ship this within 6 months"; "the platform shift continues for 2+ years" |
Save to outputs/assumption-map-[initiative]-[YYYY-MM-DD].md
I'll ask:
"Describe the initiative or strategy in 2-3 sentences. What does success look like 12 months from now?"
Surface 4-8 assumptions per category. Aim for uncomfortable assumptions - the ones the team would rather not name.
For each assumption, classify Known / Believed / Hoped with the evidence (or absence thereof) noted.
Critical = the bet fails if this assumption is wrong. Most initiatives have 3-5 Critical assumptions; if the count is higher, the initiative is too entangled and should be decomposed.
For each Critical × (Hoped or Believed), design the smallest test that would invalidate the assumption. Tests are ranked by speed-to-disconfirm, not by speed-to-confirm.
For each Critical × Hoped, write one sentence: "If this assumption is wrong, the initiative fails because…" If you can't write that sentence, the assumption isn't actually Critical.
