Publish To Nextclaw Marketplace

Publish To NextClaw Marketplace

Overview

Use this skill when the user wants to publish a local skill to the NextClaw marketplace or update an existing listing.

This skill owns the full publishing loop:

• check that the local nextclaw version is new enough,
• verify platform identity and username readiness,
• choose the correct package scope,
• run publish or update,
• then verify the listing and install path.

Do not pretend the account is ready when it is not. If the user is logged in but still has no platform username, stop and ask them to set it first.

Hard Requirement

This workflow requires NextClaw v0.17.6 or later.

Why:

• v0.17.6+ is the baseline that supports scoped marketplace package names such as @nextclaw/my-skill and @alice/my-skill.
• It also supports the clearer --scope and --package-name publish parameters.
• Personal publishing now depends on the platform username model added in the same release line.

Always verify first:

nextclaw --version

If the version is lower than 0.17.6, do not continue with a fallback flow. Tell the user to upgrade NextClaw first.

Marketplace Identity Model

Treat these fields differently:

• slug: the local skill directory name and the skill name segment
• package name: the canonical marketplace identifier, shaped like @scope/skill-name

Publishing scopes:

• official scope: @nextclaw/<skill-name>
• personal scope: @<username>/<skill-name>

Rules:

• @nextclaw/* publishing requires admin permission or NEXTCLAW_MARKETPLACE_ADMIN_TOKEN
• personal publishing requires an active platform login
• personal publishing also requires a platform username
• the personal scope must exactly match the current username

Do not blur official and personal publishing together.

Readiness Checklist

Before publishing, check these in order.

1. CLI version

nextclaw --version

Must be 0.17.6 or later.

2. Platform login

For normal user publishing, log in first:

nextclaw login --api-base https://ai-gateway-api.nextclaw.io/v1

For official @nextclaw/* publishing, an admin token may also be used through:

NEXTCLAW_MARKETPLACE_ADMIN_TOKEN=...

3. Platform username

If the user wants personal publishing, make sure the platform account already has a username.

Important:

• login alone is not enough
• the username must already exist on the NextClaw platform account
• the canonical web page is https://platform.nextclaw.io/account
• the CLI fallback is nextclaw account set-username <username>
• if it is missing, direct the user to one of those two concrete paths before publishing

4. Local skill files

The local skill directory should contain at least:

• SKILL.md
• marketplace.json

The marketplace metadata should be complete and explicit. At minimum, verify:

• slug
• name
• summary
• summaryI18n.en
• summaryI18n.zh
• description
• descriptionI18n.en
• descriptionI18n.zh
• author
• tags

Do not publish with half-complete bilingual metadata.

Publish Flow

Use the official marketplace API domain:

https://marketplace-api.nextclaw.io

Do not use a workers.dev endpoint as the default public publishing target.

Publish a new personal skill

nextclaw skills publish ./my-skill \
  --meta ./my-skill/marketplace.json \
  --scope alice \
  --api-base https://marketplace-api.nextclaw.io

Equivalent explicit package name form:

nextclaw skills publish ./my-skill \
  --meta ./my-skill/marketplace.json \
  --package-name @alice/my-skill \
  --api-base https://marketplace-api.nextclaw.io

Publish an official NextClaw skill

nextclaw skills publish ./my-skill \
  --meta ./my-skill/marketplace.json \
  --scope nextclaw \
  --api-base https://marketplace-api.nextclaw.io

Only do this when admin permission is actually present.

Update an existing skill

nextclaw skills update ./my-skill \
  --meta ./my-skill/marketplace.json \
  --package-name @alice/my-skill \
  --api-base https://marketplace-api.nextclaw.io

Default decision rule:

• if the marketplace item does not exist yet, use publish
• if it already exists, use update

Post-Publish Verification

After publishing, verify the remote item directly.

Example:

curl -sS https://marketplace-api.nextclaw.io/api/v1/skills/items/%40alice%2Fmy-skill

Check for:

• HTTP 200
• correct canonical packageName
• expected slug
• complete bilingual summary and description
• install kind is marketplace

Then do an install smoke in a temporary directory outside the repo or target workspace:

tmp_dir="$(mktemp -d)"
nextclaw skills install @alice/my-skill --api-base https://marketplace-api.nextclaw.io --workdir "$tmp_dir"
find "$tmp_dir" -maxdepth 3 -type f | sort
rm -rf "$tmp_dir"

The point is to verify real installability without polluting the current repo.

Failure Modes

Version too old

• Symptom: scoped publish flags or username-aware flow are missing
• Action: upgrade to NextClaw v0.17.6 or later

Not logged in

• Symptom: publish rejects because there is no active platform identity
• Action: run nextclaw login --api-base https://ai-gateway-api.nextclaw.io/v1

Username missing

• Symptom: personal publish fails because the platform account has no username
• Action: open https://platform.nextclaw.io/account or run nextclaw account set-username <username>, then retry

Scope mismatch

• Symptom: publish rejects @scope/name because the scope does not match the current username
• Action: publish under @<your-username>/<skill-name> instead

Insufficient permission for @nextclaw/*

• Symptom: official scope publishing is rejected
• Action: use an admin account or NEXTCLAW_MARKETPLACE_ADMIN_TOKEN, otherwise switch to personal scope

Success Criteria

This skill is working correctly when:

• it refuses to continue on nextclaw < 0.17.6
• it distinguishes official and personal scope correctly
• it does not treat login as a substitute for username readiness
• it publishes or updates through marketplace-api.nextclaw.io
• it verifies the remote item and install path after upload
