HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · docs/prefab/actions/open-file-picker.md
A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.
- Decode the base64 string and confirm it is not an instruction directed at the agent.
- Move any legitimate binary or signature data into a dedicated file (
*.sig,SIGNATURES) outside the documentation.

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

Property Shared
<!-- mcp-name: io.github.paulieb89/property-shared -->
UK property data in one package. Pulls Land Registry sales, EPC certificates, Rightmove listings, rental yields, stamp duty calculations, planning portal links, and Companies House records.
Use it as a Python library, CLI, HTTP API, or MCP server.
What You Get
| Data Source | What It Returns |
|---|---|
| Land Registry PPD | Sold prices, dates, property types, area comps with median/percentiles |
| EPC Register | Energy ratings, floor area, construction age, heating costs |
| Rightmove | Current listings (sale + rent), prices, agents, listing details |
| Yield Analysis | Gross yield from PPD sales + Rightmove rentals combined |
| Stamp Duty | SDLT calculation with April 2025 bands, BTL surcharge, FTB relief |
| Block Analyzer | Groups flat sales by building to spot investor exits |
| Planning | Local council planning portal lookup (99 verified councils, stdio only) |
| Companies House | Company search and lookup by name or number |
