Personality-as-Code for ElizaOS agents. Live market data from 370K+ indexed products. Zero config required.
plugin-undesirables gives any ElizaOS agent a structured personality, live market data from multiple free APIs, and 16 specialized skills — with zero configuration required.
Install the plugin, and your agent immediately gets:
- A working personality — a demo soul loads automatically. NFT holders get their unique AI identity.
- Live market data — real product prices from 370K+ indexed TCG products, DeFi yields from DeFiLlama, on-chain balances from Etherscan.
- 16 live-data skills — market analysis, portfolio checks, entry signals, exit strategies, risk assessment, yield farming, content creation, and more. All financial skills fetch real data.
- Passive market intelligence — an evaluator that detects card/market topics and enriches the agent's context with live pricing data automatically.
The Undesirables ecosystem has three tiers. The plugin is the free entry point.

The plugin provides free personality and data. The Oracle API provides paid computational intelligence. The MCP server provides local tool access. Each tier works independently.
npm install plugin-undesirablesAdd to your ElizaOS character.json:
{
"plugins": ["plugin-undesirables"]
}That's it. Your agent loads a demo personality with all 16 skills and live Oracle data. No wallet, no API key, no workspace download needed.
For enhanced on-chain data (portfolio checks, whale tracking), set an optional Etherscan API key:
{
"plugins": ["plugin-undesirables"],
"settings": {
"ETHERSCAN_API_KEY": "your-free-etherscan-key"
}
}If you own an Undesirable NFT, download your soul workspace from the-undesirables.com and point the plugin to it:
{
"plugins": ["plugin-undesirables"],
"settings": {
"UNDESIRABLES_WORKSPACE": "/path/to/your/soul_workspace"
}
}Your agent gets a unique personality derived from your NFT's visual traits — Big Five psychology scores, an archetype, a strategy style, persistent memory, and a predictions ledger. No two souls are alike.

|---|---|

Each soul workspace contains a SOUL.md with structured personality data:
name: "Doña Crypto"
archetype: "The Oracle"
strategy: "Long-term accumulation with high conviction"
adjectives: ["analytical", "patient", "contrarian"]
openness: 82
conscientiousness: 91
extraversion: 34
agreeableness: 45
neuroticism: 28The undesirables-soul provider injects this context into every agent response. Two different Undesirable agents will give completely different takes on the same question, filtered through their individual psychology.
Workspaces are keyed by runtime.agentId. Multiple Undesirable agents can run in the same ElizaOS instance without personality collision.
| Measure | Implementation |
|---|---|
| Path traversal protection | getSafePath() validates boundaries + resolves symlinks via fs.realpathSync |
| YAML injection | Parsed with js-yaml JSON_SCHEMA (no function execution). __proto__, constructor, prototype keys stripped. |
| Prompt isolation | Skill content wrapped with security warning — treated as inert reference material |
| Oracle fetch | 8-second timeout via AbortSignal, redirect: "error" prevents SSRF |
| Error handling | LLM failures return safe user-facing message — no prompt context leaked |
| Multi-agent safety | Workspace state keyed by agentId — no cross-agent state leakage |
| Issue | Solution |
|---|---|
Workspace /path/ does not exist |
Check the path in your character.json. Must be an absolute path. Windows: use double backslashes \\. |
| No personality detected | If no UNDESIRABLES_WORKSPACE is set, the demo soul loads automatically. Check the console for 🐸 log messages. |
| Oracle data not appearing | The Oracle provider triggers on TCG-related keywords. Try asking about a specific card by name. |
