scratch-org-snapshots

Use this skill when configuring pre-created scratch org pools for parallel CI testing, reducing pipeline wait times by claiming pre-warmed orgs instead of provisioning on demand. Covers CumulusCI pool commands, Dev Hub allocation planning for pools, pool sizing strategies, and CI matrix integration. NOT for basic scratch org lifecycle (use scratch-org-management), scratch org definition files (use org-shape-and-scratch-definition), or test data seeding (use data-seeding-for-testing).

Use this skill when designing, configuring, or troubleshooting scratch orgs: definition file structure, edition selection, allocation limits, Org Shape, CI automation via ScratchOrgInfo, and lifecycle management from the Dev Hub. NOT for SFDX CLI basics (use sf-cli-and-sfdx-essentials), sandbox management, or production org administration.

Use this skill when authoring, debugging, or optimizing a scratch org definition file (project-scratch-def.json): schema structure, features array, settings hierarchy, Org Shape sourcing, edition selection, orgPreferences-to-settings migration, and release pinning. NOT for scratch org lifecycle management (use scratch-org-management), CI pipeline design, or sandbox configuration.

Use when writing or reviewing Visualforce pages, Apex controllers, or LWC components that output user-supplied data, build dynamic queries, or construct HTTP responses. Triggers: 'XSS in Visualforce', 'SOQL injection vulnerability', 'how to encode output in Apex', 'JSENCODE Visualforce', 'open redirect prevention'. NOT for Apex CRUD/FLS enforcement (use soql-security or apex-crud-and-fls), NOT for Shield encryption (use shield-encryption-key-management), NOT for AppExchange security review process (use secure-coding-review-checklist).

Use when hardening or modernizing legacy Visualforce pages — covers the platform CSRF token model and when disabling it is a security regression, view state encryption guarantees and the 170 KB ceiling, FLS/CRUD enforcement gaps on `<apex:outputField>` and on getters that return sObjects, `<apex:includeScript>` interaction with the org Content Security Policy, hosting LWC inside a VF page via `lightning:container` / `lightning-out`, and the retire-vs-harden-vs-leave-alone decision for an inventory of legacy pages. Triggers: 'should I rewrite this Visualforce page in LWC', 'CSRF protection disabled on Visualforce page is that safe', 'community user sees a field they should not on a Visualforce page', 'view state encryption is that enough for sensitive data', 'how do I host an LWC inside a Visualforce page', 'apex:dynamicComponent and apex:actionFunction safe to keep'. NOT for greenfield Visualforce architecture (use apex/visualforce-fundamentals — controller types, view state pattern selection, PDF rendering); NOT for Visualforce email template authoring (use apex/visualforce-email-templates if/when that skill is authored); NOT for general Apex security review across triggers and async (use apex/soql-security and security/secure-coding-review-checklist).

Transaction Security policy creation and configuration: condition builder, enhanced policies, enforcement actions (block, MFA, notification, end session), real-time monitoring mode, and policy troubleshooting. NOT for Event Monitoring log analysis or Shield Event Monitoring setup (use event-monitoring). NOT for Apex testing or debug-log analysis.

Diagnosing broken SAML SSO into Salesforce — IdP-initiated vs SP-initiated flows, signing-certificate validity / expiry, NameID format mismatches, RelayState handling, audience / entityId / issuer mismatches, clock skew, the SAML Assertion Validator in Setup, the Login History debug log, and the My Domain prerequisite for SSO. Covers the standard diagnostic loop: read the SAML response, identify which check failed, fix at the IdP or SP. NOT for OAuth / OpenID Connect SSO (see security/oauth-openid-troubleshooting), NOT for setting up SSO from scratch (see security/sso-saml-setup).

Configure Shield Platform Encryption with customer-supplied (BYOK) or customer-held (Cache-Only Key Service) tenant secrets, rotate them, and recover. NOT for Classic Encryption or field masking.

Use when designing Salesforce Shield Event Monitoring retention, SIEM routing, and storage-tier strategy — which event types to keep, for how long, where, and how to answer audit queries across hot/warm/cold tiers. Triggers: 'shield event log retention', 'route event monitoring to splunk', 'how long to keep login history', 'siem salesforce integration', 'event monitoring storage tier'. NOT for enabling Shield (see salesforce-shield-deployment).

Use this skill when configuring session timeout values, concurrent session limits, session IP locking, or logout behavior in Salesforce. Covers org-wide session settings, profile-level overrides, Connected App session policies, and Metadata API SecuritySettings deployment. NOT for OAuth token refresh flows, login IP ranges, or MFA/identity-provider configuration.

Enforce step-up authentication for sensitive pages/objects using High Assurance session level and login flow policies. NOT for initial MFA enrollment UX.

Use when designing credential rotation for integration users, connected apps, named credentials, and OAuth client secrets in Salesforce. Covers rotation cadence, zero-downtime handover, secret storage, and detection of stale credentials. Triggers: 'rotate integration user password', 'connected app secret rotation', 'named credential rotation', 'stale service account', 'zero downtime secret rotation'. NOT for end-user password policies.
