Install via skills.sh and pre-approve lium bash calls

[arhangel66]

Two changes toward the packaging pattern Vast.ai uses for its agent skill.

Install through the Agent Skills standard

npx skills add Datura-ai/lium-skill --skill lium already resolves the skill from this repo layout — no restructuring needed. It is now the documented primary install path: one command, works in every agent that supports the standard, and it records a skills-lock.json entry so the skill can be updated later. The existing agents/install.sh stays as the no-node fallback.

Verified end to end: installed from a local checkout into a scratch project, both SKILL.md and references/ landed under .claude/skills/lium/.

Added a README — the repo had none, and the install command is the first thing a visitor needs.

Pre-approve lium bash calls

allowed-tools: Bash(lium:*) in the skill frontmatter drops the permission prompt on every CLI invocation during the turn that loads the skill. Per the Claude Code docs this field only grants permission; it does not narrow the tool pool (that is disallowed-tools), so the SDK half of the skill is unaffected.

Notes

llms-full.txt is unchanged: the generator strips frontmatter and does not inline llms.txt. Ran ./scripts/build-llms-full.sh anyway to confirm no drift.
