What it does
Plugin Marketplace is an agent skill from evolution-foundation/evo-nexus. Browse the EvoNexus plugin marketplace, searching for plugins by keyword, tag, or capability. Use when the user wants to find a plugin, asks what plugins are available, or describes a need that might have a plugin. Triggers on "procura plugin de X", "marketplace de plugins", "plugins disponíveis para Y", "tem algum plugin que faz Z".
Its SKILL.md is about 710 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. The repository describes itself as: The open source operating system for AI-powered businesses.
When your agent uses it
- The user wants to find a plugin
- Asks what plugins are available
- Describes a need that might have a plugin
- Procura plugin de X
Example prompts
- “procura plugin de X”
- “marketplace de plugins”
- “plugins disponíveis para Y”
- “/plugin-marketplace”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Fetch registry
- Filter by user intent
- Render results
- Offer to install
What it can do on your machine
Read from SKILL.md and the folder at commit 7f5dd76. 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 python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 Marketplace loads about 709 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 238 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 238 words (~709 tokens).
“Browse the curated registry.json from github.com/EvolutionAPI/evonexus-plugins plus community plugins. Help the user find what they need and hand off to plugin-install when they pick one.”
