source-driven-development — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited source-driven-development (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.

source-driven-development verifies technical correctness against authoritative external sources. It prevents agents from implementing framework, library, API, or platform patterns from stale memory.
This skill does not replace spec-driven-development. It verifies the technical decisions inside a spec, plan, or implementation.
spec-driven-development = what we are building and why
source-driven-development = whether the technical pattern is correct todayUse this workflow when any decision depends on external technical truth:
state management, migrations, deployment, or testing.
"documented", or "standards-compliant" implementation.
Do not use this workflow for pure product intent, copy changes, simple local logic, naming cleanup, or code whose correctness does not depend on an external versioned source.
Use this as a verification layer:
New feature:
spec-driven-development -> source-driven-development if technical docs matter
-> planning-and-task-breakdown -> test-driven-development
Existing spec:
review-spec -> source-driven-development if technical docs matter
-> planning-and-task-breakdown
Implementation/review conflict:
source-driven-development finds docs/spec mismatch -> spec-evolutionIf official sources contradict the approved spec, do not silently change the spec or implementation. Route through spec-evolution and ask the user to approve the updated path.
Use the strongest available source for the specific decision:
| Priority | Source |
|---|---|
| 1 | Official framework, library, product, or API documentation |
| 2 | Official migration guides, release notes, changelogs, or RFCs |
| 3 | Official standards bodies or platform references such as MDN/web.dev |
| 4 | Runtime compatibility data from maintained compatibility references |
Do not use community posts, Stack Overflow, tutorials, AI summaries, or memory as primary evidence when official sources are available.
State the exact decision being verified:
Decision to verify: <framework/library/API pattern>
Why it matters: <risk if wrong>
Affected spec/plan/code: <file/section/task if known>If there is no concrete technical decision, return to spec-driven-development, review-spec, or planning-and-task-breakdown.
Read the smallest relevant files to identify versions and runtime context:
package.json, lockfiles, vite.config.*, next.config.*pyproject.toml, requirements.txt, framework settingsgo.mod, Cargo.toml, composer.json, GemfileIf the version cannot be determined and version affects the answer, ask the user or mark the decision as UNVERIFIED.
Use official docs for the specific feature, not a broad homepage. Prefer deep links to the page or section that supports the decision.
Capture:
Classify the result:
CONFIRMED: official sources support the proposed pattern.ADJUST: official sources support a different pattern; update proposal viaspec-evolution if the spec was already approved.
CONFLICT: official sources and existing codebase conventions disagree;present options and ask.
UNVERIFIED: no authoritative source was found or version is unknown.Do not overrule local architecture automatically. If current docs and existing code disagree, surface the tradeoff:
Option A: follow current official docs
Option B: match existing project convention
Option C: adapt via a compatibility wrapperFor any non-obvious decision, include the evidence in the spec, plan, review, or final response:
## Source Verification
**Decision:** [technical pattern]
**Stack/version:** [detected version or unknown]
**Sources:** [official URLs or local docs]
**Result:** CONFIRMED | ADJUST | CONFLICT | UNVERIFIED
**Impact:** [spec/plan/code consequence]If the discovery reveals a durable caveat, use annotate to persist it.
| Thought | Required correction |
|---|---|
| "I know this API." | Memory is not evidence. Verify version-sensitive patterns. |
| "The docs will take too long." | A wrong framework pattern costs more than a targeted docs check. |
| "The spec already says what to use." | Specs can be technically stale; verify external truth when it matters. |
| "A popular blog says this is best practice." | Use official sources first. Blogs can inform, not authorize. |
| "The docs conflict with our code; I'll just pick one." | Present the conflict and route through spec-evolution if approved scope changes. |
| "I could not verify it, but it is probably fine." | Mark it UNVERIFIED and narrow the claim. |
Stop and ask before proceeding when:
or architecture change not already approved.
