React AI Infra

react-ai-infra

A meta-skill that wires APM (Agent Package Manager) and the team's curated React skill set into an existing React project across Claude Code and GitHub Copilot.

This skill does not scaffold the React project itself — the user is expected to have already run create-next-app, create-tsrouter-app, npm create vite, or equivalent. What this skill owns is the agent-asset layer: apm.yml, bundled skills and rules, and the framework-specific AGENTS.md.

What this skill does

When to use

• A React/Next.js/TanStack Start/Vite repo already exists (or has just been created via its own CLI) and needs the team's agent assets wired in.
• An existing React repo needs Claude Code + Copilot parity (skills + rules in both ecosystems).
• Onboarding APM-managed dependencies (e.g. react-best-practices) into a project.

When NOT to use

• Non-React projects.
• The repo has not been created yet — run create-next-app / create-tsrouter-app / npm create vite first, then come back.
• The user only wants to install one APM package — call apm install <pkg> directly.
• The project must NOT install APM (some monorepos pin tooling versions).

Required inputs

• A working directory that is the project root (where package.json lives — this skill does not create it).
• apm CLI installed and on PATH (verified in Step 0).
• An interactive session for Step 2's framework prompt. In a non-interactive run, the skill MUST fail fast with a clear message rather than guess (see Step 2 below).

Workflow

0. Verify apm is installed

Before any other step, run apm --version (or apm targets) via whichever shell has apm on PATH. On Windows the installer typically registers apm only for PowerShell, so Git Bash / WSL-style shells may report command not found even when apm is installed — fall back to PowerShell before declaring it missing. If the command is not found in any available shell OR returns a non-zero exit code, stop immediately and print this message to the user verbatim:

APM (Agent Package Manager) is not installed or not on PATH.
Install it first:

  Windows (PowerShell):  irm https://aka.ms/apm-windows | iex
  macOS / Linux:         curl -sSL https://aka.ms/apm-unix | sh
  Homebrew:              brew install microsoft/apm/apm
  pip:                   pip install apm-cli

After installing, re-run this skill.
Docs: https://github.com/microsoft/apm

Do not generate apm.yml, do not copy bundled assets — exit cleanly so the user can install APM and retry.

1. Detect target environments

Inspect the project root for these markers:

If neither .claude/ nor .github/ exists, ask the user which targets to scaffold (default: both). Record the chosen target list — it drives apm install --target and the local-copy steps.

Extending targets later. The detected list is committed to apm.yml in Step 3, and Step 3's merge rule keeps an existing targets: block untouched (see references/install-workflow.md § 3b). If the user later adds .github/ to a Claude-only setup and re-runs the skill, the new target will NOT be added automatically — they must manually edit targets: in apm.yml and re-run apm install. This is intentional conservative behavior; the union-on-extend variant is tracked separately.

2. Ask which React framework

Prompt the user to pick exactly one framework:

Which React framework is this project using?
  1) Next.js          (slug: nextjs)
  2) TanStack Start   (slug: tanstack-start)
  3) Vite + React     (slug: vite-react)

Record the chosen slug as <framework>. Step 7 is the only consumer — apm.yml and the bundled skills/rules in Steps 3–6 are framework-agnostic for now. The slug also decides whether Step 7 deploys anything at all: only nextjs ships an AGENTS.md template; the other two skip Step 7 with a logged notice (see references/agents-md-deployment.md).

Do NOT auto-detect. The user is the source of truth — a repo may have leftover config from a previous framework, or be mid-migration.

Non-interactive runs (e.g. CI without a TTY): fail fast with react-ai-infra requires a framework choice (nextjs / tanstack-start / vite-react). Re-run in an interactive session or pass the framework explicitly. Do not guess and do not proceed past this step.

3. Generate or merge apm.yml

• If <project-root>/apm.yml does not exist:
  • Read templates/apm.yml (relative to this skill).
  • Resolve the project name: take package.json name, or fall back to the directory basename. Strip any @scope/ prefix (@org/foo → foo) and replace whitespace with -.
  • Substitute <project-name> with the resolved value.
  • Set the targets: field (plural, block-style list) to the detected target list. The list MUST always include agent-skills alongside any per-client targets. Do NOT use the singular target: or inline-array form [a, b] — current APM CLI versions reject both.
  • Write the file.
• If <project-root>/apm.yml exists:
  • Parse both YAMLs.
  • Union dependencies.apm and dependencies.mcp (deduplicate by canonical string).
  • Preserve all user-set keys; only add what is missing.
  • Re-write the merged result.

See references/apm-yml-template.md for schema details.

4. Run apm install

Build the command:

apm install --target <comma-separated-targets>

Example: apm install --target claude,copilot,agent-skills

• Print the exact command and pause for user confirmation before executing.
• On user approval, run via whichever shell has apm on PATH (see Step 0 — usually PowerShell on Windows, Bash on macOS/Linux/WSL).
• Stream output. If exit code ≠ 0, surface the error and stop — do not proceed to local deployment.

Side effects to expect: apm install writes installed packages to apm_modules/ at the project root, and recent APM versions auto-append apm_modules/ to .gitignore (creating one if missing). Surface this in the Step 8 report so the user is not surprised by the new ignore entry.

Heads-up for Step 7: when the copilot target is active, apm install may itself emit an AGENTS.md at the project root. Before running this command, record agents_md_existed_pre_apm = file_exists(<project-root>/AGENTS.md) so Step 7 can distinguish "APM just wrote this" from "the user had it before we got here." See references/agents-md-deployment.md for why this matters.

5. Deploy bundled skills

For each subdirectory <name> under <this-skill>/skills/:

• Always copy the entire directory tree to <project-root>/.agents/skills/<name>/ (cross-client target).
• If the claude target is active, also copy to <project-root>/.claude/skills/<name>/.

Skills are copied verbatim — no frontmatter transformation needed (Claude Code and Copilot both consume SKILL.md with the same frontmatter shape).

6. Deploy bundled rules (with frontmatter transform)

For each <name>.md under <this-skill>/rules/:

• Claude target (claude selected): copy verbatim to <project-root>/.claude/rules/<name>.md. Source paths: frontmatter is kept as-is.
• Copilot target (copilot selected): transform frontmatter and write to <project-root>/.github/instructions/<name>.instructions.md.
  • paths: ["src/**/*.{tsx,jsx}"] becomes applyTo: "src/**/*.tsx,src/**/*.jsx"
  • See references/frontmatter-transform.md for the full algorithm and edge cases.

Create destination directories if they do not exist.

7. Deploy framework-specific AGENTS.md

Source: <this-skill>/templates/agents/<framework>.md. Destination: <project-root>/AGENTS.md.

Step 7 is specified in references/agents-md-deployment.md.

• If no template ships for the chosen framework (currently anything other than nextjs), skip cleanly with a logged notice. Not an error.
• Otherwise follow that reference verbatim for branch selection, marker handling, APM coexistence (uses agents_md_existed_pre_apm captured in Step 4), and report strings.

8. Verify and report

• List every file created / overwritten with its absolute path.
• Confirm the apm install exit status.
• Report whether <project-root>/apm_modules/ was created or updated by apm install (Step 4 side effect).
• Report whether <project-root>/.gitignore was created or updated by apm install (specifically whether apm_modules/ was appended).
• Highlight any merge advisories from apm.yml (Step 3) or AGENTS.md (Step 7).
• Suggest the user reload their agent (Claude Code: /reload-plugins; Copilot: restart VS Code) so new skills are picked up.

Output format

Targets detected: claude, copilot, agent-skills
Framework:        nextjs

apm.yml: created (or: merged — added 1 dependency)
apm install: success

Side effects:
  - apm_modules/: created
  - .gitignore: updated (appended `apm_modules/`)
  # both come from `apm install` itself; omit a line if the corresponding
  # path was unchanged on this run.

Deployed skills:
  - .claude/skills/no-use-effect/SKILL.md
  - .agents/skills/no-use-effect/SKILL.md

Deployed rules:
  - .claude/rules/react-components.md
  - .github/instructions/react-components.instructions.md (frontmatter: paths -> applyTo)

AGENTS.md:
  - <one of the report strings from references/agents-md-deployment.md>
  # e.g. "AGENTS.md: created (template nextjs.md)"
  # or   "AGENTS.md: appended managed block below APM-generated content"
  # or   "No AGENTS.md template for vite-react yet — skipped"

Next steps:
  - Reload your agent so it picks up the new skills/rules.

References

Bundled assets

To add a new bundled skill: drop it under skills/<name>/. To add a new rule: drop it under rules/<name>.md with paths: frontmatter. To add an AGENTS.md template for another framework: drop it under templates/agents/<framework-slug>.md wrapped in <!-- BEGIN:<framework-slug>-agent-rules --> / <!-- END:<framework-slug>-agent-rules --> markers, then update the framework → template table in references/agents-md-deployment.md. All three are picked up automatically by Steps 5 / 6 / 7.
