Skill Publish
Publish Claude Code plugins and standalone Agent Skills with proper versioning, changelog management, and git workflow.
Determine Publish Type
Before starting, identify the publish type based on project structure:
| Indicator | Type |
|---|
.claude-plugin/plugin.json
exists | Claude Code Plugin |
| Standalone with no plugin manifest | Standalone Agent Skill |
Claude Code plugins publish by pushing to GitHub — the marketplace picks up the latest commit on the default branch automatically. No registry upload or OTP is needed.
Standalone Agent Skills follow the agentskills.io specification and distribute as directories containing
.
Claude Code Plugin Workflow
1. Check Current State
bash
# Read current version from manifest
cat .claude-plugin/plugin.json | grep '"version"'
# Check git is clean and up to date
git fetch origin && git status
# Review commits since last version bump
git log --oneline $(git describe --tags --abbrev=0 2>/dev/null || echo HEAD~10)..HEAD
2. Bump Version in plugin.json
Edit
.claude-plugin/plugin.json
to increment the version field. For early-stage plugins (0.x.x or 1.0.x), bump the patch version unless the user requests otherwise:
0.1.6 → 0.1.7
1.0.23 → 1.0.24
3. Update CHANGELOG.md
If a changelog exists, add an entry following the existing format:
markdown
## [X.X.X] - YYYY-MM-DD
### Added
- New features
### Changed
- Changes to existing functionality
### Fixed
- Bug fixes
Summarize commits since the last release into appropriate categories.
4. Validate Plugin Structure
Before publishing, verify the plugin is well-formed:
.claude-plugin/plugin.json
has required field
- Component directories (commands/, agents/, skills/, hooks/) contain valid files
- Skills have with valid YAML frontmatter (name + description)
- Agents and commands have files with YAML frontmatter
- Referenced files and scripts exist
5. Commit and Push
Critical: Pushing to the default branch IS publishing. The Claude Code plugin marketplace automatically picks up the latest commit.
bash
git add .claude-plugin/plugin.json CHANGELOG.md
# Also stage any changed skill/agent/command files
git add -A
git commit -m "Release vX.X.X"
git push origin <default-branch>
6. Verify Publication
After pushing, verify the plugin update is available:
bash
CLAUDECODE= claude plugin update <plugin-name>@<publisher>
The
prefix is required to avoid nested session errors when running from within Claude Code.
Note: The marketplace may take a few minutes to reflect the new version.
7. Update Downstream References
If the plugin version is tracked elsewhere (e.g., a marketplace page, documentation, or
), update those references to match the new version.
Standalone Agent Skill Workflow
For skills not bundled in a Claude Code plugin, follow the agentskills.io specification.
1. Validate SKILL.md
Verify frontmatter meets the spec. For details, consult
references/agentskills-spec.md
.
Required fields:
- : 1-64 chars, lowercase alphanumeric + hyphens, must match directory name
- : 1-1024 chars, describes what and when
Optional fields:
2. Validate Structure
skill-name/
├── SKILL.md # Required
├── scripts/ # Optional executables
├── references/ # Optional docs loaded on demand
└── assets/ # Optional static resources
3. Version via Metadata
Track version in the frontmatter
field:
yaml
metadata:
author: org-name
version: "1.1.0"
4. Distribute
Standalone skills distribute as directories. Common methods:
- Git repository (push to GitHub)
- Archive (zip the skill directory)
- Package registry (if applicable)
Common Issues
Plugin Not Updating
If
does not pick up changes:
- Verify the push landed on the default branch (usually or )
- Check that
.claude-plugin/plugin.json
is valid JSON
- Wait a few minutes for marketplace propagation
Version Already Exists
If the version string was already used in a previous commit, bump again to the next patch before pushing.
Nested Session Error
Always prefix CLI commands with
when running from within an active Claude Code session to avoid the "nested session" error.
