[Feature]: Update all skills from a source with `skills update <owner/repo>`

🤖 AI generated content. Claude Code/claude-opus-5-5

Problem

skills add takes a source (owner/repo), but skills update only takes skill names. There's no way to update every skill that came from one source.

The natural guess fails:

$ npx skills update dwjohnston/agent-skills
Updating dwjohnston/agent-skills…

No installed skills found matching: dwjohnston/agent-skills

This matters when a project installs skills from several sources and you only want to refresh the ones from your own repo.

Proposed Solution

Let skills update accept a source as well as skill names. An argument that looks like a source (owner/repo, a GitHub URL, etc.) would update every installed skill whose lock entry has that source:

# Update every skill installed from this source
npx skills update dwjohnston/agent-skills

# Existing behaviour unchanged
npx skills update my-skill
npx skills update

A --source <source> flag would work too, if mixing the two kinds of positional argument is too ambiguous.

Alternatives Considered

Workaround: read the names out of skills-lock.json with jq:

npx skills update -p -y $(jq -r '.skills | to_entries[] | select(.value.source == "dwjohnston/agent-skills") | .key' skills-lock.json)

It works, but it relies on the lock file format and needs jq.

Additional Context

Seen on skills 1.7.6.

Related issues

• #528 (closed): asked for skills update <name> to update a single skill. It was fixed in #913, which is why a source passed to update is now treated as a skill name.
• #982 (closed): skills update -p <name> installed every skill from the source repo, not just the named one. That is roughly the behaviour requested here, but it happened by accident and was fixed as a bug.
