Code Execution

Use this skill to actually run things: compile a program, execute a script, test code someone shares with you, check what a command outputs, or work with files. Running code is how claims about code become knowledge — a program that compiles and passes its tests teaches you more than any amount of reading it.

Choosing the tool

1. safe_shell — one shell command with guarded defaults. The right first reach for compiling, running installed binaries, checking versions, and inspecting the environment (which, ls, language toolchains on PATH).
2. execute_code — run a code snippet directly in a supported runtime without touching the filesystem.
3. run_script — a saved multi-step script when the work has real structure.
4. write_file + safe_shell — the classic loop for languages the runtime doesn't embed: write the source file, invoke its compiler or interpreter from the shell, read the output.

Practice

• State what you ran and show the real output — including failures. A compile error is a finding, not an embarrassment.
• Working files belong in the workspace directory; clean up what has no lasting value.
• When a language or binary is missing from PATH, say so plainly and name what you checked (which <name>). Absence of a toolchain is a fact about the environment, never something to paper over with imagined output.
• Long or destructive operations deserve a sentence of intent before you run them.
