react-doctor/public-env-secret-name
A public-prefixed env var whose name implies a secret (token, password, private key, service role) is inlined into the client bundle, so a real credential there is world-readable.

Validation prompt
Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.
Fires in client (browser-bundled) code when a public-prefixed env var: NEXT_PUBLIC_, VITE_, REACT_APP_, or EXPO_PUBLIC_: has a NAME containing SECRET, TOKEN, PASSWORD, PRIVATE, DATABASE_URL, SERVICE_ROLE, AWS_ACCESS_KEY, or AWS_SECRET. It reports the first such name that is NOT on the trusted-public allowlist (Sentry DSN, *PUBLISHABLE*, Supabase ANON_KEY, PostHog/Mixpanel/Mapbox tokens, Algolia search key, Google Maps key, *PUBLIC_KEY*, and *_(DISABLE|ENABLE|ALLOW|REQUIRE)_* feature flags). Matching is name-only: it never inspects the value.
Suppress when: a value that is genuinely client-safe despite a scary name: a vendor's designated publishable/anon token not yet allowlisted, or a boolean flag like NEXT_PUBLIC_ENABLE_SECRET_MENU; confirm only when the name denotes a real credential that would be inlined into the bundle.
Evidence boundary
The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.
Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.
Record one outcome:
- Confirmed failure: The required evidence establishes the violation.
- Rejected: A documented exception or false-positive predicate applies.
- Needs evidence: Named evidence can still be collected.
- Unavailable: Required evidence cannot be collected in this run.
- Waived with evidence: An authorized, scoped exception applies to an established failure.
- Observation: The review records an optional tradeoff without claiming a defect.
A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.
Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.
Fix prompt
Apply this candidate correction only after the required evidence confirms the risk.
If it is a real credential, move it to a server-only env var (drop the public prefix) and read it from server code or a backend route, because every NEXT_PUBLIC_/VITE_/REACT_APP_/EXPO_PUBLIC_ value is embedded in client JavaScript. Rotate it if it ever shipped in a bundle. If the value is genuinely public, rename it to a non-secret form (for example *_PUBLISHABLE_KEY, *_ANON_KEY) so it stops tripping the check.
Repository-wide copy prompt
Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.

Required change:
- If it is a real credential, move it to a server-only env var (drop the public prefix) and read it from server code or a backend route, because every
NEXT_PUBLIC_/VITE_/REACT_APP_/EXPO_PUBLIC_value is embedded in client JavaScript. Rotate it if it ever shipped in a bundle. If the value is genuinely public, rename it to a non-secret form (for example*_PUBLISHABLE_KEY,*_ANON_KEY) so it stops tripping the check.
Validation before editing:
Fires in client (browser-bundled) code when a public-prefixed env var: NEXT_PUBLIC_, VITE_, REACT_APP_, or EXPO_PUBLIC_: has a NAME containing SECRET, TOKEN, PASSWORD, PRIVATE, DATABASE_URL, SERVICE_ROLE, AWS_ACCESS_KEY, or AWS_SECRET. It reports the first such name that is NOT on the trusted-public allowlist (Sentry DSN, *PUBLISHABLE*, Supabase ANON_KEY, PostHog/Mixpanel/Mapbox tokens, Algolia search key, Google Maps key, *PUBLIC_KEY*, and *_(DISABLE|ENABLE|ALLOW|REQUIRE)_* feature flags). Matching is name-only: it never inspects the value.
Suppress when: a value that is genuinely client-safe despite a scary name: a vendor's designated publishable/anon token not yet allowlisted, or a boolean flag like NEXT_PUBLIC_ENABLE_SECRET_MENU; confirm only when the name denotes a real credential that would be inlined into the bundle.
Constraints:
- Make the smallest change that fixes the root cause.
- Preserve behavior and interfaces unrelated to this diagnostic.
- Reuse existing project components, utilities, and conventions.
- Keep validation and authorization on trusted boundaries. Do not replace them with client-only checks.
- Adapt identifiers and framework details instead of copying blindly.
- Do not disable the rule or suppress matching code.
- Confirm this rule is enabled for the project:
client (browser-bundled) production source files; server dirs (api/backend/server/middleware/route/functions/lambdas/workers, *.server.*) and docs trees skipped.
Assessment:
- Record detector evidence, applicability facts, assumptions, missing evidence, and the rule class for this occurrence.
- Return one outcome: Confirmed failure, Rejected, Needs evidence, Unavailable, Waived with evidence, or Observation.
- A waiver records the established failure, scope, authority, evidence, and review or expiry condition. It is not a pass or false positive.
Verification:
- Run focused tests for the changed behavior.
- Run React Doctor and confirm this diagnostic no longer appears from changed code.
- Run an unfiltered scan of the affected scope before claiming no cross-category regression.
- Report the files changed and any checks you could not run.
