Four gaps in react-design.md's Fluent UI rules — a MUST with no runtime signal, a host the contract never names, a validation step that proves nothing about accessibility, and a missing motion rule — each with a runnable snippet. Pre-PR working notes, not a changelog.
SPFx
The 16 Rules Your AI Should Follow Before Writing One Line of Fluent UI
Ask an AI coding agent for a Fluent UI card and it often hands back a hardcoded div with invented colors, because generic React training data has never heard of SharePoint's theme constraints. This post walks through react-design.md's 16-section "Copilot UI Contract," the SPFx Dev Skills rule set that stops that failure before an agent writes a single component.
Making the SPFx Upgrade Playbook Safer: A Roadmap for Rollbacks, Big Jumps, and CI
Post 4 covered upgrade.md as it exists today. This companion post proposes four concrete, testable extensions — an explicit rollback path when a report can't be fully applied, an incremental strategy for multi-major-version jumps, running the existing test suite as part of verification, and machine-readable JSON output for agent-driven diffing — each framed as a future contribution to SharePoint/spfx-dev-skills, not a criticism of it.
SPFx Can’t Hold Application Permissions — Here’s Exactly Which Copilot APIs That Rules Out, and the SharePoint Copilot Apps Preview That Bridges the Gap
SPFx can call Microsoft Graph, but it can never hold an application permission — a structural fact of the browser execution model that quietly rules out several Microsoft 365 Copilot APIs no matter how the manifest is configured. This post traces the exact rule API by API, shows the documented AadHttpClient-to-backend pattern for everything SPFx can't reach directly, and evaluates SharePoint Copilot Apps — Microsoft's own preview answer to packaging SPFx with Copilot — as the series closes with a design-review checklist and the complete 13-post map.
The Upgrade Playbook: How AI Agents Should (and Shouldn’t) Touch Your SPFx Version
Scaffolding fails safe — a bad attempt just gets deleted. An upgrade runs against a project that already works, so the cost of getting it wrong is much higher. This post walks the spfx-dev-skills upgrade.md reference end to end: the clean-git-state precondition, version detection via .yo-rc.json, the exact m365 spfx project upgrade commands, applying the report in order without overwriting customizations, and the build-clean bar for calling an upgrade done.
Four Ways We’d Extend SPFx Scaffolding (And the Exact Commands to Test)
Post 2 covered create.md as it exists today. This companion post proposes four concrete, testable extensions — scaffold commands for Library and Adaptive Card Extension, a workflow for adding components to an existing solution, the --sharepoint-version flag for on-premises targets, and a post-scaffold validation/commit step — each framed as a future contribution to SharePoint/spfx-dev-skills, not a criticism of it.
Stop Letting AI Hang on yo @microsoft/sharepoint: Non-Interactive SPFx Scaffolding
Interactive Yeoman prompts are invisible to AI coding agents — they hang, or worse, pick the wrong menu item. This post walks the official spfx-dev-skills create.md reference line by line: environment checks with m365 spfx doctor, the fully flag-based scaffold command for web parts and extensions, dependency install discipline, and toolchain-aware packaging for Heft vs. gulp.
Your AI Coding Agent Doesn’t Know SPFx — Here’s the Skill Pack That Fixes It
AI coding agents hang on interactive Yeoman prompts, invent package versions, and hand-roll UI instead of using Fluent UI — because generic training data doesn't know SharePoint Framework's narrow conventions. SharePoint/spfx-dev-skills is an official agent skill pack that fixes this: this post breaks down what it is, how it's structured, and two rules worth adopting today even without an AI agent.
The Future of SPFx Scaffolding: Roadmap, GA Timeline, and What’s Coming Next
`@microsoft/spfx-cli` is targeting GA around September 2026 — though as of this writing that date looks increasingly likely to slip, and Microsoft's own sources disagree on whether it ships with SPFx 1.24 or 1.25. After GA, the Yeoman generator receives its final update. This post covers the Phase 2 and 3 roadmap, the MCP server front-end for AI-assisted scaffolding, and how SPFx developers can prepare today.
Custom Templates and CI/CD with `@microsoft/spfx-cli`
`@microsoft/spfx-cli` is designed for automation. This post covers custom org templates, CI/CD integration with GitHub Actions, air-gapped scaffolding, the scaffold log, and the `@microsoft/spfx-template-api` SDK for programmatic use in enterprise tooling.
