FluidFramework

Use when customer-facing API changes were made — i.e., API report .md files differ from the branch's resolved comparison base. Guides through release tag assignment, API Council review requirements, breaking change classification, deprecation process, and changeset guidance. Triggered automatically by ci-readiness-check when api-report diffs are detected.

IMMEDIATELY USE THIS SKILL when creating or develop anything and before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Use when implementing user interfaces or user experiences - guides through exploration of design variations, frontend setup, iteration, and proper integration

Use when the user explicitly asks for a CI check or to push their branch — e.g. "ci readiness", "check ci", "pre-push check", "ready for CI", "ci check", "ready to push", "push my changes", "push the branch", "let's push". Catches common CI failures before pushing — formatting, stale API reports, missing changesets, policy violations.

Internal reusable workflow for resolving the correct Git comparison base for branch reviews and change analysis. Finds the PR target or canonical Fluid Framework upstream, selects the newest shared target-history commit, and detects substantial divergence.

Use this skill when faced with a difficult debugging task where you need to replicate some bug or behavior in order to see what is going wrong.

Use when you need to create a new custom skill for a profile - guides through gathering requirements, creating directory structure, writing SKILL.md, and optionally adding bundled scripts

Generate the OCE shift status dashboard. Triggers on: 'generate shift dashboard', 'show dashboard', 'shift status', 'status dashboard', 'what's going on', or any request for a NON-SPECIFIC overview of current OCE status (incidents, pipelines, errors).

Use this skill for any Kusto query or telemetry investigation specifically related to Fluid Framework or its partners. Triggers include: writing or running a Kusto query against the Office Fluid database, investigating Fluid Framework telemetry or error rates, querying Office_Fluid_FluidRuntime_* tables, looking up a Fluid session by Session_Id or docId, investigating a Fluid-related error in Loop or Whiteboard telemetry, monitoring an FF bump or partner ring deployment, checking Fluid render reliability or Scriptor errors, or when the user mentions Fluid-specific tables (Office_Fluid_FluidRuntime_*, OwhLoads, HostTracker, Scriptor) or Fluid-specific error types (dataCorruptionError, dataProcessingError, DeltaConnectionFailureToConnect, ICE, ACE). Do NOT trigger for general Kusto questions that are not related to Fluid Framework.

Use this when you have completed some feature implementation and have written passing tests, and you are ready to create a PR.

Use when creating a pull request in the Fluid Framework repo. Composes a PR title and body following Fluid Framework conventions, proposes them to the user, then pushes the branch and creates the PR on GitHub. Triggers on "create a PR", "make a PR", "open a PR", "submit a PR", or "push and create a PR".

Use when composing, writing, drafting, or reviewing a PR title, PR description, or PR body in Fluid Framework — provides title style, body template, and section guidance.

Fluid Framework client release group — minor releases, patch releases, and post-release type test updates. Covers release prep, branching, version bumps, changelogs, release notes, and type test baselines. In autonomous mode, auto-detects state from the schedule and repo, attempts to execute, and falls back to a GitHub issue on failure. Triggers on "release", "do the release", "release status", version bump, release notes, changelog, release branch, or release engineering.

Use this skill to split large plans into smaller chunks. This skill manages your context window for large tasks. Use it when a task will take a long time and cause context issues.

Triage test failures in an Azure DevOps pipeline run for Fluid Framework. Use when the user shares an ADO build/pipeline URL or build ID and wants failures analyzed, when they ask "why did this pipeline fail", "summarize the test failures", "is this test flaky or a real bug", "compare these runs", or wants bugs filed for genuine failures. Covers the Real Service End to End Tests pipeline as the worked example but applies to any FF test pipeline.

This skill should be used when the user asks to "run policy check", "check policy", "policy-check", or needs to validate package compliance. Provides guidance on running policy checks for specific packages or the entire repository.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Use when asked to review code, review a branch, or do a code review. Spawns Breaker (correctness) and API Analyst (compatibility/conventions) sub-agents while the orchestrator reviews architecture, tests, performance, and security.

The authority on pulling a pull request — Azure DevOps or GitHub — into an isolated local worktree so a human can review it in their editor, and on posting human-controlled review comments back to the PR (ADO via the ado PR-thread MCP tools or the Azure DevOps REST API, GitHub via the gh CLI). Auto-detects the platform and all identifiers from the PR URL; not tied to any specific repository. The AI assists an interactive human review and only ever posts comments the human explicitly requests. If you find yourself checking out a PR branch over the user's own working tree, or posting AI-authored review prose the human did not ask for, invoke this skill instead.

Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior

ALWAYS load this skill if it is not already loaded, for ANY user query or conversation - establishes the Nori workflow, protected-branch check, operating mode, tone, and coding guidelines before any other work

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Trigger ADO pipelines for a Copilot-created PR by posting /azp run comments. Use when the user asks to trigger CI pipelines for a specific PR.
