jakub-plichcinski MIME artifact sample
Activation Patterns
Minimal fixture for MIME coverage. Skill root = this directory (SKILL.md, notes.txt, conf/, scripts/).
The next four layers each run one bundled script via a shell contract: interpreter, flags / args where useful, cmd, timeout_seconds. Success is exit code 0 only (no grep). Run forward from the skill root as cwd (or set KAIROS_MIME_SAMPLE_ROOT to this directory).
Must Never
- Store secrets in these fixtures.

Run hello.py (python3)
Layer text: run the Python artifact with python3, -B, and pass the script path via args (same argv shape the server builds for interpreter + -c + trailing args).
{"contract":{"type":"shell","required":true,"shell":{"interpreter":"python3","flags":["-B"],"args":["scripts/hello.py"],"timeout_seconds":25,"cmd":"import subprocess, sys; sys.exit(subprocess.run([sys.executable, sys.argv[1]], check=False).returncode)"}}}
Run hello.sh (sh)
Layer text: run the shell artifact with sh as interpreter; cmd is a one-line script that invokes scripts/hello.sh so $0 inside the file stays correct.
{"contract":{"type":"shell","required":true,"shell":{"interpreter":"sh","timeout_seconds":20,"cmd":"sh scripts/hello.sh"}}}
Run hello.cjs (node)
Layer text: run the JavaScript artifact with node as interpreter; cmd is a one-liner that spawnSync the same binary on scripts/hello.cjs.
{"contract":{"type":"shell","required":true,"shell":{"interpreter":"node","timeout_seconds":25,"cmd":"require('child_process').spawnSync('node', ['scripts/hello.cjs'], {stdio: 'inherit'}).status && process.exit(1)"}}}
Run hello.pl (perl)
Layer text: run the Perl artifact with perl and -w in flags; cmd runs scripts/hello.pl via system and exits with the child status.
{"contract":{"type":"shell","required":true,"shell":{"interpreter":"perl","flags":["-w"],"timeout_seconds":20,"cmd":"system($^X, 'scripts/hello.pl'); exit($? >> 8)"}}}
Reward Signal
All four script layers completed with exit code 0.
