What it does
Plugin Creator is an agent skill from ananddtyagi/cc-marketplace. Create, validate, and publish Claude Code plugins and marketplaces. Use this skill when building plugins with commands, agents, hooks, MCP servers, or skills.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Hooks and plugins. It works with Model Context Protocol. The repository describes itself as: Marketplace repo for Claude Code Plugins.
When your agent uses it
- Building plugins with commands
- Tasks that involve Hooks and plugins
Example prompts
- “/plugin-creator”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Create a GitHub repository
- Add .claude-plugin/marketplace.json
- Add plugin directories
- Users install via
What it can do on your machine
Read from SKILL.md and the folder at commit b643305. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json, markdown and bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
anthropic.com
Also links to:
github.comcode.claude.comclaude-plugins.devagentskills.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Plugin Creator loads about 2.2k tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 420 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 420 words (~2,233 tokens).
“This skill provides comprehensive guidance for creating Claude Code plugins following the official Anthropic format (as of December 2025).”
