code-apps

A guide for Power Apps Code Apps, which are standard React, Vue, or TypeScript web apps built with Vite and hosted inside Microsoft Power Platform. The platform provides environment access and related controls without a separate server to manage.

In plain words
What is it for?
Use it to create, run, build, publish, and promote a Code App, connect it to Dataverse or other connectors, and organize several apps in one repository.
Why use it?
It explains how Code Apps differ from PCF controls and Canvas apps, and how to keep the app build and environment configuration consistent. This avoids using the wrong Power Platform development model.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-apps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Power Apps Code Apps

Power Apps Code Apps is the code-first SPA hosting model: a standard web app (React/Vue/TS, built with Vite) that imports the @microsoft/power-apps client library and is published into a Power Platform environment, where the platform handles Entra authentication, DLP, sharing, and Conditional Access. It is distinct from PCF (components inside model-driven forms) and Canvas apps (built in maker studio). Keep the app source-controlled, build before every push, and treat power.config.json as the bridge between the local project and the target environment.

When to use this

  • Scaffold a new code app from the Microsoft Vite template and initialize it against an environment.
  • Add Dataverse (or connector) data sources and use the generated typed services for CRUD.
  • Run the app locally, build it, and push it to a Power Platform environment.
  • Work in a repo that uses the multi-app CodeApp/ folder pattern (several code apps side by side).
  • Plan ALM promotion (Dev → Test → Prod) via solutions, pipelines, and connection references.

For a control embedded inside a model-driven form, use pcf-and-web-resources. For Dataverse schema or data operations behind the app, use dataverse-schema and data-operations.

Helpers

Helpers live in the plugin's scripts/ directory at the plugin root, not inside this skill folder. Resolve the plugin root and invoke them:

  • Claude Code: python "$CLAUDE_PLUGIN_ROOT/scripts/push_code_app.py" --help
  • Codex: python "$CODEX_PLUGIN_ROOT/scripts/push_code_app.py" --help (also exposed as $PLUGIN_ROOT)
  • Standalone / unsure: the scripts/ folder sits beside this skill bundle; invoke by its path within the install.
Helper Use it to
push_code_app.py Build (npm run build) and push a code app. Defaults to the npm CLI (npx power-apps push); pass --cli pac for legacy pac code push and --solution-name <unique> to target a specific solution. Use --path <dir> to point at one app, --all to push every app under a CodeApp/ folder in sequence, --dry-run to preview, and --skip-build only when pushing already-compiled output.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

code-apps is a skill published in the GitHub repository satriotsubasa/PowerPlatform-Core (17 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 203 tokens to every session and 1,560 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
