experience-ui-bundle-deployforcedotcom/sf-skillsMUST activate when the project has a uiBundles//src/ directory and the task involves deploying to an org or post-deploy org setup. Deploys a UI bundle app and runs ordered setup: org auth, build, metadata deploy, permission-set and role assignment, Experience Cloud self-registration, social login / SSO / IDP linking (Auth Providers + SAML SSO configs on a React site), seed-data import, and GraphQL schema fetch + codegen. Trigger signals: .network-meta.xml, org-setup.config.json (with a socialLogin block), data-plan.json, sfdx-project.json, or mentions of deploy, org setup, or social login / SSO / IDP linking on an Experience site. DO NOT TRIGGER when: creating a new UI bundle project (use experience-ui-bundle-project-generate); styling pages without deploying (use experience-ui-bundle-frontend-generate); adding a feature such as auth, search, or file upload without deploying (use the matching experience-ui-bundle-*-generate skill); configuring MFA permission sets (use experience-ui-bundle-mfa-configure).API Design4.7kexperience-ui-bundle-salesforce-data-accessforcedotcom/sf-skillsMUST activate whenever a uiBundles//src/ project reads, writes, or displays Salesforce data — INCLUDING building a page, list, table, card grid, dashboard, or form that shows, filters, counts, or edits records of any object (e.g. Property__c, Account, Case), even when the prompt names only the UI or the object and never says query, GraphQL, or SDK. Records behind such a component come from Salesforce, so use this ALONGSIDE experience-ui-bundle-frontend-generate: that skill styles the component, this one wires its data. Also triggers on @salesforce/platform-sdk imports, sdk.graphql.query / mutate / sdk.fetch calls, .graphql files, or stale data needing force-refresh. New read/write work uses the current @salesforce/platform-sdk API; migrate only EXISTING old @salesforce/sdk-data callable code. Not for pure styling/layout with no records, app shell, file upload, or auth/search scaffolding. DO NOT TRIGGER for OAuth, object/field schema changes, Bulk/Tooling/Metadata API, or declarative automation.API Design4.7kplatform-agentsetup-categories-fetchforcedotcom/sf-skillsFetch agentic setup prompt categories from a connected Salesforce org using the Connect API. Use this skill to call GET /agenticsetup/categories and return the list of prompt categories, optionally with their nested prompts. TRIGGER when: user asks to get, fetch, list, or show agentic setup categories, prompt categories, setup copilot categories, prompt library categories, available setup prompts, Agentforce prompt library, or copilot prompts. DO NOT TRIGGER when: user wants to create new categories, work with non-categories endpoints, or generate OpenAPI specs.API Design4.6kdata360-schema-getforcedotcom/sf-skillsRetrieve Data Lake Object (DLO) and Data Model Object (DMO) schema information from Salesforce Data Cloud using REST APIs.

inngest-durable-functionsinngest/inngest-skillsUse when building functions that must survive process crashes, retry automatically on failure, run on a schedule, react to events, or maintain state across infrastructure failures — e.g., webhook handlers that drop events, flaky cron jobs, background jobs that fail mid-execution, or workflows that need to resume where they left off.

Heads up — OnCall OSS is in maintenance mode (archived March 2026); Grafana Cloud users should use IRM.API Design2.7k
