At a glance

Auto-format code via the developer CLI - backend (.NET via JetBrains cleanupcode), frontend (oxfmt + oxlint --fix), and the developer CLI itself.

  • Frontend & Design work in your project
  • SKILL.md covers Examples and Always pass --quiet
  • Calls dotnet

What it does

Format is an agent skill from platformplatform/PlatformPlatform. Auto-format code via the developer CLI - backend (.NET via JetBrains cleanupcode), frontend (oxfmt + oxlint --fix), and the developer CLI itself.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. It works with .NET and JetBrains IDEs. The repository describes itself as: A platform designed for building enterprise-grade, multi-tenant products using Azure, .NET, React, TypeScript, Infrastructure as Code, etc. The licence is MIT.

When your agent uses it

  • Frontend & Design work in your project

Example prompts

  • “/format”

What it can do on your machine

Read from SKILL.md and the folder at commit 269de1c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • dotnet

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Format loads about 445 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 138 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~445

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Auto-format code via the developer CLI - backend (.NET via JetBrains cleanupcode), frontend (oxfmt + oxlint --fix), and the developer CLI itself.

Format

bash
dotnet run --project developer-cli -- format [--backend] [--frontend] [--cli] [--self-contained-system <name>] [--no-build] [--all-files] --quiet

Use developer-cli exactly as written - do not expand to an absolute worktree path.

  • --backend - .NET (JetBrains cleanupcode)
  • --frontend - React/TypeScript (oxfmt + oxlint --fix)
  • --cli - the developer CLI itself
  • --self-contained-system <name> - narrows backend formatting to one SCS (e.g. account, main)
  • --no-build - skip the dotnet tool restore step (faster after a recent run)
  • --all-files - format every file in the solution. Default is to format only .cs files changed against origin/main (faster).

No arguments formats everything (changed-only by default). Unformatted code fails CI - commit all changes, never revert.

After build succeeds, run format, lint, test in parallel with --no-build.

Examples

bash
dotnet run --project developer-cli -- format --quiet                                            # everything
dotnet run --project developer-cli -- format --backend --quiet                                  # all backend
dotnet run --project developer-cli -- format --frontend --quiet                                 # frontend
dotnet run --project developer-cli -- format --backend --self-contained-system account --quiet  # one SCS

Always pass --quiet

Verbose output goes to a log file. On success the CLI prints a single line; on failure it prints a short error message - read the log if you need details. Backend is slow - run last. Frontend is fast.
