agent-config-lint@1.0.0
CAUTION· install onlyPublisher claims: "Check agent config for things that break silently on someone else's machine. Use before publishing or committing a SKILL.md, AGENTS.md, CLAUDE.md or llms.txt, before publishing a skill to ClawHub, when a skill "works on my machine" but not for a teammate, when a skill fails to trigger, or when asked to review agent config. Catches references to files that do not exist, absolute paths under the author's home directory, undeclared CLI dependencies, a frontmatter name that does not match the skill's directory, and two skills whose descriptions are so similar the agent fires the wrong one." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
