Probe now emits KEY=VALUE so the agent reads facts instead of inferring
from prose. Stdlib-only (no tomllib) so it runs on whatever Python the
launcher reaches. Adds sh/ps1 launcher pair, SCRIPTS_UV/SCRIPTS_DIR/
SCRIPTS_STORE env-var contract, tainted-venv + recipe + default-package
detection, and broader mode classification (incl. agent-tool-only).
SKILL.md trimmed and gated by pyproject.toml glob.
Introduce two new plugins: dioxus and project-uv with metadata
READMEs and SKILL documentation and example skill files
Update marketplace.json to advertise both plugins
