multi-channel-skill-publisher

Release one skill everywhere — without maintaining three diverging copies.

The three channels

Channel	What it is	Publish via
ClawHub Skill	searchable skill registry entry	web UI (most reliable) or clawhub publish <dir> --slug <slug>
ClawHub Package (bundle-plugin)	plugin package, source-linked to a GitHub commit	clawhub package publish <abs-path> --family bundle-plugin …
Claude Code plugin	installable via /plugin from a plain GitHub repo	just git push — the repo IS the marketplace

0. Layout: one source of truth (SSOT)

Never hand-maintain copies. Canonical files live once, everything else is generated:

repo/
  SKILL.md            <- SSOT (canonical skill text; YAML frontmatter: name + description)
  skill.json          <- SSOT (registry metadata; THE version number lives here)
  sync.py             <- copies SSOT into every target + stamps the version everywhere
  clawhub-skill/      <- generated copy for clawhub publish
  plugin/                          <- the ONE plugin folder, served to BOTH plugin channels
    .claude-plugin/plugin.json     <- Claude Code manifest (name, displayName, version, …)
    openclaw.plugin.json           <- OpenClaw manifest, REQUIRED for bundle-plugin publish:
                                      {"id": "...", "name": "...", "version": "...", "configSchema": {}}
    skills/<name>/SKILL.md         <- generated from SSOT
    commands/<name>.md             <- optional slash command ($ARGUMENTS)
  .claude-plugin/marketplace.json  <- makes the repo its own Claude Code marketplace:
                                      {"name": "...", "owner": {...}, "plugins": [{"name": "...", "source": "./plugin"}]}

sync.py (concept): read version from skill.json, copy SKILL.md into clawhub-skill/ and plugin/skills/<name>/, stamp the version into plugin.json, marketplace.json, openclaw.plugin.json. Run it after EVERY edit of the SSOT files.

Make sync.py also run a version preflight: query the live version on both namespaces (clawhub inspect <slug> + clawhub package inspect <name>, parse Latest: x.y.z) and refuse to sync unless skill.json is strictly higher. That turns two whole gotcha classes ("version already exists", web-UI drift) into a hard error before anything reaches the registry. Known blind spot: a just-published version still in the moderation scan is invisible to inspect on BOTH namespaces — the preflight can't see it, and republishing the same number fails at the registry instead.

Release procedure

1. Edit only the SSOT files (SKILL.md, skill.json).
2. Bump the version in skill.json — it must be HIGHER than what is live on both namespaces:

   clawhub inspect <skill-slug>          # skill: Latest: x.y.z
   clawhub package explore <plugin-name> # package: [Bundle Plugin] version
   

3. Sync: python3 sync.py
4. Commit + push — MANDATORY before step 6 (the package publish links a commit SHA that must exist on GitHub):

   git add -A && git commit -m "Version -> <v>" && git push
   git rev-parse HEAD
   

   First release ever? Bootstrap repo + push in one step: gh repo create <owner>/<repo> --public --source . --push
5. Publish the skill. For a FRESH publish (new slug, no rename) the CLI works — use an ABSOLUTE path:

   clawhub publish "$(pwd)/clawhub-skill" --slug <skill-slug> --name "<Display Name>" --version <v>
   

   When a rename is involved or the CLI misbehaves, use the web UI: skill page → new version → re-select the folder fresh (browser caches the old selection) → type the display name EXACTLY into the name field → set version → publish.
6. Publish the package (bundle-plugin) — CLI works reliably here; use an ABSOLUTE path:

   clawhub package publish "$(pwd)/plugin" \
     --family bundle-plugin \
     --name <plugin-name> --display-name <DisplayName> \
     --version <v> \
     --host-targets claude-code \
     --source-repo <owner>/<repo> \
     --source-commit <HEAD-SHA> \
     --source-ref refs/heads/main \
     --source-path plugin
   

7. Claude Code channel: nothing to do — users install with /plugin marketplace add <owner>/<repo> → /plugin install <plugin-name>@<marketplace-name>.

Verify

clawhub inspect <skill-slug>             # Latest == <v>
clawhub package explore <plugin-name>    # Bundle Plugin == <v>

Right after publishing, clawhub inspect returns "Skill is hidden by moderation (pending.publication)" until the security scan clears — transient at first, NOT a failed publish. Poll every ~30 s instead of republishing. Similarly, clawhub package inspect <name> may say "Package not found" while package explore already lists it (indexing/moderation lag) — trust explore for existence.

If it STAYS hidden: your content likely tripped the moderation scanner. clawhub unhide <slug> --yes does NOT work — moderation hides are Forbidden for the owner ("contact a moderator"). Self-serve fix: clean the flagged content, bump, and publish a higher version; escalate to a moderator only if that doesn't surface it. Meanwhile the profile page shows the skill missing under "Skills" while the plugin twin is visible under "Plugins" — that asymmetry is the tell that moderation, not the publish, is the problem.

Gotchas — CLI bugs & workarounds (each cost a real debugging session)

• clawhub rename is broken: it errors newSlug required even when the new slug IS provided. Rename via the web UI instead. And after a rename, CLI publish may still only match the original slug — another reason the web UI is the safer skill-publish path.
• --name on clawhub publish (skill flow) can throw a server error — observed on EXISTING/renamed skills; on a fresh first publish (CLI v0.9.0) it worked fine. If it errors: omitting it makes the display name fall back to the folder name (you get a skill literally called "Clawhub Skill"); fix by typing the display name exactly into the web UI name field.
• Web-UI upload caches the folder selection. After editing files, re-select the folder fresh or the scanner shows stale content. Sanity check: the file list/preview must show your newest files.
• EVERY clawhub path argument must be absolute — both clawhub publish (skill) and clawhub package publish error with Path must be a folder on a relative path. Always pass "$(pwd)/<dir>".
• After a failed publish the server rate-limits retries (~45 s). Don't hammer; fix the cause, then retry once. Read errors (inspect, package inspect) carry the hint too — the (reset in Ns) suffix tells you how long to wait.

Gotchas — registry behavior

• ClawHub search is NAME-driven, not description-semantic. Put the search tokens users will type into the skill name/slug (e.g. known-error-fixes-database), not only the description.
• Skill and package namespaces are separate. The same name can exist as both; clawhub inspect <name> may hit the skill entry — use clawhub package inspect / package explore for packages.
• --family code-plugin requires a package.json (it means a Node/code plugin, e.g. an MCP server). A skill bundle is --family bundle-plugin.
• bundle-plugin requires openclaw.plugin.json at the plugin root — minimal valid manifest: {"id", "name", "version", "configSchema": {}}. hostTargets/format do NOT go in the manifest; they are CLI flags (--host-targets, format auto-detects claude from .claude-plugin/plugin.json).
• The Claude Code marketplace needs the repo to be public; a fresh git push is all a "release" takes on that channel.

Gotchas — versioning bugs

• Versions are permanent and the display name follows the HIGHEST version number. A stray high version from CLI experiments hijacks the displayed name (and cannot be deleted); the only fix is publishing an even higher version. Never publish throwaway/test versions to your real slug.
• "Version already exists" errors mean the live version is >= yours. Check BOTH namespaces before bumping (skill and package are versioned independently — clawhub inspect <skill-slug> + clawhub package explore <plugin-name>). The sync.py preflight automates exactly this check.
• Web-UI publishes bypass your repo → version drift. Publishing (or auto-bumping) via the web UI updates the registry but NOT your local skill.json; the next repo-driven release then fails as "too low" or silently ships an older number. After ANY web-UI publish, write the live version back into the SSOT skill.json and run sync.py — its preflight flags the drift (live > local) as a hard error.
• Keep ONE monotonic version across all channels. The sync script must stamp the same number into skill.json, plugin.json, marketplace.json, and openclaw.plugin.json — hand-edited manifests drift apart within a release or two.
