powertoys-verification

microsoft/PowerToys/.github/skills/powertoys-verification/SKILL.md

Verify PowerToys behavior end-to-end with the winapp CLI across two scenarios: (A) a module's release checklist against the installed build; (B) PR validation — derive each PR's checklist from its description + diff, then drive it against the installed build (a merged/shipped PR, or a whole release/hotfix set) or by building + sideloading the module when the PR isn't in the build yet (unmerged or not-yet-released). Drive each item via UIA invoke / Named Events / settings.json edits / clipboard / GPO / SendInput, and emit a structured PASS / FAIL / BLOCKED verdict per item with evidence (FAIL distinguishes product defects from stale/ambiguous checklist items). Use when asked to verify a module checklist, validate a PR, sign off a release/hotfix's PRs, or QA installed/sideloaded PowerToys bits. Combines generic winapp ui mechanics (references/winapp-ui-testing.md) with PT-specific recipes, per-scenario playbooks (references/scenarios/), and the helper .ps1 files shipped with this skill.

Run PowerToys UITest.Next suites in persistent Hyper-V VMs over PowerShell Direct. Validate full default and constrained suites on Windows 10 and Windows 11, plus applicable ARM64 guests, then automatically hand implementation tasks to ui-tests-pipeline-ci for commit/push and CI validation. Local green is not end-to-end completion. Use for agentic UI-test iteration, reusable standard-user desktops, payload staging, evidence export, VM customization, clean baselines, or hosts without nested virtualization.

ui-tests-pipeline-ci

microsoft/PowerToys/.github/skills/ui-tests-pipeline-ci/SKILL.md

Microsoft FTE-only completion workflow for PowerToys UI-test implementation: automatically continue after successful local VM suites, commit and push scoped changes, queue CI, wait synchronously, and stabilize through Azure CLI and Azure DevOps REST APIs. No separate push/run-CI request is needed for create, migrate, or stabilize tasks unless the user limited scope. Also use for explicit UITests CI, setup preflight, 401/403 diagnosis, build reuse, recordings/artifacts, and the three-run limit. Keywords: FTE, az, Azure CLI, Azure DevOps, pipeline, UI Test Automation, UITests CI, commit, push, local-to-CI handoff, buildNow, specificBuildId, uiTestModules, CI flake.

codex / code-mode-host

openai/codex/codex-rs/code-mode-host/AGENTS.md

Do not use timeouts or sleeps to synchronize tests. Wait for explicit signals or observable state; let the test runner enforce test-case timeouts.

codex / sandbox_integrity

openai/codex/codex-rs/exec-server/src/sandbox_integrity/AGENTS.md

These checks currently emit telemetry only. Findings and preparation errors must not change sandbox construction, permissions, approvals, or command execution. Supported backends are Seatbelt, bubblewrap, and MXC; legacy Windows is out of scope. - Backends supply complete dependency inventories and interpret the request's original filesystem policy: resolve command temp directories and MXC volumes, and reuse the backend's deny-glob expansion where enforcement expands globs. - The runner prepares dependency facts and invokes each checker per dependency. Checkers remain independent of inventories…

imagegen

openai/codex/codex-rs/skills/src/assets/samples/imagegen/SKILL.md

Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas.

openai-docs

openai/codex/codex-rs/skills/src/assets/samples/openai-docs/SKILL.md

API first-timers, Codex/Work Q&A. If the user already has an OpenAI API integration, skip this skill for API questions and use the developer docs. Read this skill before answering how Codex or ChatGPT Work behaves, where to find a feature, or how to configure or troubleshoot this app or coding agent. This includes conversation history, model and cache behavior, instruction precedence, permissions, and tool availability. Use for API onboarding only when the user is connecting to the OpenAI API for the first time. Skip action requests, such as scheduling an automation, and tasks fully answered by supplied text or data.
