At a glance

Coding and testing rules for Mistral Vibe so code works on Linux, macOS and Windows even though CI runs the test suite on Linux only.

  • Writing code that touches paths, shells or Windows-specific handling
  • SKILL.md covers Code rules, Terminal data and Testing
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Parsing terminal or PTY output that arrives in chunks

What it does

Because the machine a contributor develops on is not the one that gates the pull request, the rules require code to be correct on every platform and provably so on those CI cannot run. Code must not rely on host behavior such as shell, path separator, line endings or case sensitivity. Platform branches go through the helpers in vibe.core.utils.platform, such as is_windows and resolve_windows_shell, rather than ad hoc sys.platform checks, and paths are built with pathlib.Path.

Terminal and PTY data are treated as arbitrarily chunked streams: normalize CRLF before reading a lone carriage return as a redraw, buffer incomplete control sequences, and add regression tests that run on Linux and cover every split boundary. Tests for other platforms run on Linux by monkeypatching sys.platform, environment variables and probes like shutil.which instead of skipping them, and platform-dependent assertions must force the platform explicitly.

When your agent uses it

  • Writing code that touches paths, shells or Windows-specific handling
  • Parsing terminal or PTY output that arrives in chunks
  • Adding tests for Windows behavior that must run on Linux CI

Example prompts

  • “Add Windows shell resolution to this command runner and test it on Linux with monkeypatching.”
  • “Fix the path handling in the config loader so it works on Windows and macOS.”

Requirements

  • The Mistral Vibe repository and its platform helpers

What it can do on your machine

Read from SKILL.md and the folder at commit 4ae5c59. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Vibe Cross-Platform Rules loads about 551 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 241 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~551

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.

Vibe Cross-Platform

Vibe ships on Linux, macOS, and Windows, but CI runs the test suite on Linux only. The machine you develop on is not the machine that gates the PR — code and tests must pass on every platform, and must be provably correct on the platforms CI cannot exercise.

Code rules

  • Never rely on host-specific behavior (shell, path separator, line ending, available binaries, $SHELL, case sensitivity). Assume the same code runs under cmd.exe, Git Bash, zsh, and sh.
  • Branch platform-specific logic behind the helpers in vibe.core.utils.platform (is_windows(), resolve_windows_shell()), not ad-hoc sys.platform checks. Keep POSIX-only assumptions (forward slashes, POSIX shlex escaping, $SHELL) out of shared paths and scope Windows-only handling to is_windows().
  • Use pathlib.Path for path composition; never hardcode / or \\.

Terminal data

  • Treat terminal and PTY data as arbitrarily chunked streams: normalize CRLF before interpreting lone \r as an in-place redraw, buffer incomplete control sequences until their terminator arrives, and add Linux-runnable regression tests covering CRLF plus every split boundary of representative control sequences.

Testing

  • Test other-platform code paths on Linux by monkeypatching sys.platform, env vars, and probes like shutil.which — do not @pytest.mark.skipif them away. A Windows-only behavior with no Linux-runnable test is untested in CI.
  • When an assertion depends on the platform, force it explicitly (e.g. monkeypatch.setattr(module, "is_windows", lambda: True)) instead of letting the test pass only because of the host it happened to run on. A test that would flip its result on a different OS is a bug.
