ping-orchestration-android-sdk
ping-orchestration-android-sdk
pingidentity / ping-sdk-agent-skills

Guide for building Android apps that integrate with the Ping Orchestration Android SDK (also referred to as the Ping Identity Android SDK, formerly the ForgeRock Android SDK / forgerock-android-sdk; Gradle artifact: `com.pingidentity.sdks:android`; modules: `journey`, `davinci`, `oidc`, `fido`, `protect`, `externalidp`, `binding`, `oath`, `push`). Covers both new project scaffolding and adding the SDK to an existing app. Use this skill whenever the user is: (1) building any Android app that authenticates against PingOne, PingOne Advanced Identity Cloud (AIC), PingAM, or DaVinci using Journey, DaVinci, or OIDC flows; (2) configuring SDK modules (Journey, DaVinci, OIDC, FIDO/passkeys, Protect, ExternalIdP, OATH, Push, Device Binding); (3) rendering Journey callbacks or DaVinci collectors in Jetpack Compose; (4) troubleshooting Ping authentication flows in an Android app; (5) setting up token or session storage with `EncryptedDataStore`; (6) scaffolding a new Android/Kotlin project for a Ping-authenticated app; (7) implementing OIDC centralized login with `OidcWebClient`, handling browser redirects, or wiring the redirect URI intent filter for OAuth 2.0 authorization code flows. Invoke proactively even when the user phrases it loosely — "add PingOne login to my Android app", "how do I set up Journey in Android", "how do I add OIDC centralized login", "make this look like a Ping sample app", "use the Ping Android SDK", "integrate pingidentity sdk on Android", "use forgerock-android-sdk", or "migrate from ForgeRock to Ping on Android".

pingidentity / ping-sdk-agent-skills

Guide for building iOS apps that integrate with the Ping Orchestration iOS SDK (also referred to as the Ping Identity iOS SDK, formerly the ForgeRock iOS SDK / forgerock-ios-sdk; Swift Package: `Ping/ping-ios-sdk`; modules: `PingJourney`, `PingDavinci`, `PingOidc`, `PingExternalIdP`, `PingProtect`, `PingOath`, `PingLogger`, `PingStorage`). Use this skill whenever the user is: (1) building any iOS app that authenticates against PingOne, PingOne Advanced Identity Cloud (AIC), PingAM, or DaVinci using Journey, DaVinci, or OIDC flows; (2) configuring modules (Journey, DaVinci, OIDC, FIDO/passkeys, Protect, ExternalIdP, OATH, Push); (3) rendering Journey callbacks or DaVinci collectors in SwiftUI; (4) troubleshooting Ping authentication flows in an iOS app; (5) setting up token or session storage with `KeychainStorage`; (6) scaffolding a new Xcode project for a Ping-authenticated app; (7) applying Ping Identity branding to a sample app; (8) implementing OIDC centralized login with `OidcWebClient`, configuring `ASWebAuthenticationSession` or `SFSafariViewController`, handling browser redirects, or wiring `onOpenURL` for OAuth 2.0 authorization code flows; (9) analysing a PingAM/AIC Journey export JSON to identify required callbacks and generate a matching iOS sample. Invoke proactively even when the user phrases it loosely — "add PingOne login to my iOS app", "how do I set up Journey in Swift", "add OIDC centralized login", "make this look like a Ping sample app", "use the Ping iOS SDK", "use the PingSDK in my iPhone app", "integrate ping-ios-sdk", or pastes / attaches a Journey export JSON.

Agent workflows46
P
pr-create

Create a Pull Request (PR) or Merge Request (MR) from the current branch to a target branch asked of the user, with mandatory blocking quality gates before creating it: run quality-check, code-review, and trace-validate (all three must return an approved verdict) and, if docs/policies/definition-of-done.md exists, verify the code against that Definition of Done. Works on any git repository with a remote: auto-detects the platform (GitHub, GitLab, Bitbucket, Gitea, Azure Repos, etc.) from the remote and uses the available CLI. Auto-generates the title and description from the commits and creates the PR in a single pass. Always use whenever the user asks to create, open, generate, raise, or submit a PR, MR, pull request, or merge request, even if they only say "create the PR" or "push it to develop" without naming the platform.

principle-build-the-lever
principle-build-the-lever
q-qp-p / pstack

Apply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun

Development46
P
principle-encode-lessons-in-structure
principle-encode-lessons-in-structure
q-qp-p / pstack

Apply when you catch yourself writing the same instruction a second time, or notice a recurring correction. Encode the rule as a lint, metadata flag, runtime check, or script instead of more text.

principle-separate-before-serializing-shared-state
principle-separate-before-serializing-shared-state
q-qp-p / pstack

Apply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant.

Development46
P
principle-sequence-verifiable-units
principle-sequence-verifiable-units
q-qp-p / pstack

Apply to multi-step work (sweeps, migrations, runs of similar edits) and to how you stack commits and PRs. Break work into small units that each end in a verifiable state, check each before the next, and order delivery so the sequence proves itself to a reviewer.

Development46

principle-subtract-before-you-add
principle-subtract-before-you-add
q-qp-p / pstack

Apply when sequencing an addition, refactor, or rewrite. Remove dead code, redundant validators, and stub references first, then build on the simpler base.

Development46

principle-type-system-discipline
principle-type-system-discipline
q-qp-p / pstack

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
