feat(feature-mfa): add MFA skill references for react-native-auth0 and auth0-api-python [SDK-11420] by sanchitmehtagit · Pull Request #238 · auth0/agent-skills

sanchitmehtagit · 2026-10-01T07:07:43Z

Summary

Adds feature-mfa/react-native-auth0.md: skill leaf covering the v5 mfa.* sub-client API (getAuthenticators, challenge, enroll, verify), error.json.mfa_token extraction, credentialsManager.saveCredentials(), and deprecation callout for pre-v5 methods.
Adds feature-mfa/auth0-api-python.md: skill leaf covering the API-side scope gate pattern (verify_access_token/verify_request), scope splitting, and the required_claims gotcha (key presence only, not value content).
Updates feature-mfa/index.md: adds rows for react-native-auth0 and auth0-api-python.
Updates SKILL.md: wires auth0-api-python into Tier 1 and Tier 3 detection.
Adds framework-api-python/index.md stub for router reachability (required by CI when a Tier 1 slug is added to SKILL.md).

Test plan

Skill router CI passes (no unresolvable leaf paths)
auth0-api-python slug resolves in SKILL.md Tier 1 table
framework-api-python/index.md stub satisfies CI check

Summary by CodeRabbit

Documentation
- Added guidance for verifying tokens and enforcing API scopes with the Auth0 Python SDK, including handling unauthorized requests and distinguishing scope checks from claim-presence checks.
- Added React Native MFA guidance for enrollment, factor challenges, verification, credential persistence, and MFA-related errors.
- Expanded MFA references to include the Python SDK and clarify how API-side scope enforcement relates to MFA.
Framework Support
- Added the Auth0 Python API SDK to framework detection.

Adds per-SDK MFA reference files backing the four new evals in auth0/auth0-evals#341: - go-jwt-middleware (Go) — API-side scope gate on transfer:funds - Auth0.AspNetCore.Authentication.Api — API-side scope gate - Spring Security resource server — SCOPE_-prefixed authority gate - Auth0.OidcClient.* (.NET native/desktop) — client-initiated step-up Registers all four in the feature-mfa index Example code snippets table. Method/option names verified against each eval's scaffold code.

…d auth0-api-python (SDK-11420) Adds leaf files for react-native-auth0 (API-driven MFA, mfa.* sub-client, v5 deprecations) and auth0-api-python (API-side scope gate pattern). Wires auth0-api-python detection into SKILL.md Tier 1 and Tier 3. Adds minimal framework-api-python stub for router reachability. Co-Authored-By: Claude <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The changes add Python API SDK detection and integration guidance. They also add React Native MFA guidance and document how a Python API can verify tokens and enforce a required scope on an endpoint.

Changes

Python API integration

Layer / File(s)	Summary
Python API detection and integration `plugins/auth0/skills/auth0/SKILL.md`, `plugins/auth0/skills/auth0/references/framework-api-python/index.md`	Framework detection maps `auth0-api-python` signals to `api-python`. The framework reference documents SDK setup, async token verification, verification errors, and scope checks.

MFA guidance

Layer / File(s)	Summary
Client-side MFA flows `plugins/auth0/skills/auth0/references/feature-mfa/react-native-auth0.md`	The React Native reference describes MFA error handling, authenticator listing, enrollment, challenge and verification flows, and credential handling.
Resource-server scope gates `plugins/auth0/skills/auth0/references/feature-mfa/index.md`, `plugins/auth0/skills/auth0/references/feature-mfa/auth0-api-python.md`	The MFA index lists Python API scope enforcement. The Python reference shows token verification and a `transfer:funds` check for a transfer endpoint.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Merge Risk: 🔵 Low · up to a011d

The guide gives an inaccurate deprecation version, which may mislead developers about when to move to the current MFA API. Correct the version for accurate SDK guidance; the impact is limited to documentation.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a011d

The guidance preserves server-side scope enforcement and explicitly rejects using claim-key presence as authorization. No introduced vulnerability is established, but the token-verification and post-MFA scope-issuance assumptions cannot be independently confirmed from the supplied implementation evidence.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The documented attacker-controlled input is a bearer token presented to an adopting resource API's sensitive endpoint. The evidence does not establish a deployed service, tenant count, asset inventory, or downstream privilege scope, so production blast radius remains unbounded by this review.

Trust Boundaries and Controls

observed — The leaf explicitly distinguishes token verification from authorization. It warns that required_claims checks key presence rather than permission values, and instead uses exact scope membership. These controls counter a claim-presence authorization bypass in the documented example; their effectiveness still depends on trustworthy token validation and scope issuance.

Review comments at
@plugins/auth0/skills/auth0/references/feature-mfa/auth0-api-python.md:
- Line 67: Update the SDK examples note in the MFA scope-gate reference to
remove the outdated claim that auth0-api-python has no EXAMPLES.md, and
acknowledge that the upstream examples include verify_request() examples. Keep
this reference authoritative for MFA scope-gate policy.

Review comments at
@plugins/auth0/skills/auth0/references/feature-mfa/react-native-auth0.md:
- Line 75: Move the saveCredentials call out of the existing-authenticator
branch so it runs after the enrollment and existing-authenticator paths both
complete verification; obtain saveCredentials from useAuth0() and save the
credentials returned by mfa.verify().
- Line 12: Update the MFA example using useAuth0() to call its
loginWithPasswordRealm method with a single parameters object containing
username, password, and realm; remove reliance on an undeclared auth client so
the MFA error handling uses the current SDK API.
- Line 3: Update the minimum-version statement in the React Native Auth0 MFA
reference to require SDK version 5.10.0, so it does not imply that the described
mfa API is available in earlier v5 releases.

Review comments at
@plugins/auth0/skills/auth0/references/framework-api-python/index.md:
- Line 16: Assign the instance created by ApiClient to api_client so the example
can reuse it for the verification methods described below.

Addresses CodeRabbit review on PR #238, verified against react-native-auth0 v5.11.1 source and the auth0-api-python package: - react-native-auth0: useAuth0() exposes top-level loginWithPasswordRealm and saveCredentials plus the mfa sub-client, not auth/credentialsManager. Rewrite the login call and the credential-save guidance (both loginWithPasswordRealm and mfa.verify auto-persist before resolving), detect mfa_required via error.code, and correct the legacy method names (authorizeWithOTP/OOB, authorizeWithRecoveryCode, sendMultifactorChallenge). Set min version to 5.10.0 (mfa client landed in v5.10.0; legacy methods deprecated in v5.11.0). - auth0-api-python: the SDK now ships EXAMPLES.md (verify_access_token and verify_request); drop the stale "no EXAMPLES.md" claim. Correct the min version to 1.0.0b10 (only 1.0.0 pre-releases are published; 0.1.0 never existed). - framework-api-python: assign ApiClient(...) to a variable so the example can reuse it for the verification methods shown below.
