foundation-build-risk-review — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited foundation-build-risk-review (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.

Don't build it yet. First name the one assumption most likely to make it fail.
foundation-build-risk-review is a fast, pre-commitment gate for product decisions. Given an idea, a feature request, or a scope change, it returns a Build Risk Review: the single biggest risk, the evidence behind it, a verdict, and a concrete no-code validation step, then routes you to the skill that does the next piece of work. It is a foundation hub: its job is to triage and dispatch, not to duplicate the deeper skills.
Do not write code, scaffold a project, recommend a stack, or design implementation. First answer three things: should this be built, what is most likely to make it fail, and what must be validated before committing.
If the user says the work is for learning, a portfolio, or internal practice, do not judge it by market standards; still flag scope and clarity risks.
| If the ask is | Use instead |
|---|---|
| A launched product's pivot-or-persevere call, weighing usage or market data | iterate-pivot-decision |
| You have chosen the assumption and need to design the test | define-hypothesis |
| Framing a confirmed problem for the team or leadership | define-problem-statement |
| The full nine-block business model, not a single-risk read | foundation-lean-canvas |
| Ranking many features or initiatives against each other | define-prioritization-framework |
The boundary that matters most: this skill is forward-looking and pre-commitment (low or no data); iterate-pivot-decision is retrospective and post-launch (it weighs market feedback on something already shipped).
If the product is already launched and the question is whether to change direction, hand off to iterate-pivot-decision. If the request is too broad to review responsibly, ask exactly one clarifying question (complete the sentence: "this is for [who] in [situation] to solve [problem]"), then proceed. Never run a long questionnaire; at most two questions before a constrained review.
Produce a Build Risk Review with these parts:
references/risk-taxonomy.md. Not a long inventory. Add at most three to five supporting risks (R2, R3, ...).references/risk-taxonomy.md. Likes, compliments, waitlists, and market-size numbers are NOT demand. Real files, booked calls, payment, repeated manual use, or switching from an existing alternative are.Be skeptical but useful. Always separate "can be built" from "should be built". Do not flatter the idea or default to encouragement; do not say "this has potential" unless the path is specific.
| Verdict | Routes to |
|---|---|
| Build small | define-problem-statement, then deliver-prd / deliver-user-stories |
| Validate first | define-hypothesis, then measure-experiment-design |
| Pivot first | foundation-lean-canvas (re-frame the model) |
| Don't build yet | stop; or discover-competitive-analysis / discover-market-sizing for an evidence check |
| Several competing requests | define-prioritization-framework |
Full map, including the per-risk routing: references/routing-map.md.
If a routed skill is not available, do not ship a bare pointer. The library is often installed in part rather than whole, so the skill you route to may not exist in the user's environment. When you cannot confirm it is available, say so plainly and inline the minimal version of its output so the review stays executable:
| Routed skill absent | Inline instead |
|---|---|
define-hypothesis | One testable hypothesis in believe / for / will / as-measured-by form |
measure-experiment-design | A three-line experiment sketch: the one decision metric, the sample or duration needed, and the win/lose rule set before running |
define-problem-statement | A two-sentence problem frame: who, in what situation, blocked by what |
foundation-lean-canvas | The three riskiest boxes only: problem, customer segment, unfair advantage |
define-prioritization-framework | A single ranked list with the one criterion that actually decides |
discover-competitive-analysis | The two closest alternatives and the one axis on which you would lose to each today |
discover-market-sizing | One bottom-up estimate: reachable accounts, times a realistic attach rate, times annual revenue per account, labelling each of the three as sourced or assumed. All three factors are required: accounts times attach rate is a customer count, not a market size |
deliver-prd | The problem, the one success metric with its baseline, and what is explicitly out of scope |
deliver-user-stories | The three stories that carry the risk, each with one acceptance criterion that could fail |
A verdict whose next step the user cannot execute is not a finished review. Naming the gap and supplying the minimum is always better than routing into an environment that cannot follow.
