Skill Bundle
The complete installable skill directory, including `SKILL.md` and every reference, script, asset, fixture, or companion file required by the workflow.
Why it matters
Copying only the entry file can leave valid-looking instructions that point to missing resources or lose the deterministic code the workflow depends on.
In practice
Install the tree as one unit, record hashes and source revision, validate the installed copy, and show collisions before replacing an existing bundle.
Common confusion
`SKILL.md` is the entry point, not necessarily the entire artifact.
