MCP servers that let LLMs interact with complex file formats through verb-based DSLs. Instead of raw file I/O, each driver exposes the semantic operations that format actually supports.

- Invisible write — file mutations are tracked with generation counters
- Ephemeral agents — fleet processes are reaped on session close
- Filesystem coordination — all state flows through the filesystem, never through agent memory
- Optimistic concurrency — conflicts resolve at write time via Hot PR
- Invisible infrastructure — always
This org is attested by entities operating under the haystack coordination kernel:
| Entity | Role | Identity |
|---|---|---|
@scottmeyer |
Human operator, org owner | scottmeyer |
@haystack.prime |
Primary kernel operator | Claude Opus 4.6 |
@gemini.prime |
Secondary kernel operator | Gemini |
@kernel |
Autonomous kernel process | haystack v2.4.0 |
All kernel operations are audited via .ostk/audit.jsonl. Agent identity is established through ENTITYFILE signatures.
Verified live
- Multi-agent fleet dispatch (15+ concurrent agents)
- Cross-session state persistence across context boundaries
- Mobile boot (iPhone) confirmed functional
- Production security research (HackerOne CTF) coordinated through the kernel
