1. Helmryth

    A private operating system for autonomous work. Persistent operators run on the CLIs you already own, and nothing consequential runs until you answer.

    • 3,054 tests across 274 files
    • 160 routes and 76 IPC channels pinned by build gates
    • 30 product films, each shot in one take on a live build

  2. Run Phantom

    A local-first debugger that turns AI-agent traces into timelines, side-by-side comparisons and regression checks for CI.

    • 349 commits on main in three weeks
    • Windows portability from an outside contributor, 5 merged PRs
    • Reads traces from TypeScript, Python, Go and Rust with no SDK

  3. JITMIND

    Memory for long-running agents that knows when a fact stopped being true, and retrieves across four channels at once.

    • Five timestamps on every memory, across two clocks
    • BM25, dense, index and graph retrieval fused by RRF
    • As-of queries: what the agent believed on any date

Siblings. One lane vocabulary — Luna, Terra, Sol — and one rule: no lane is trusted for work it only claims to have done. FABLEWRIGHT runs inside Claude Code and Codex; ORRERY serves six clients as an MCP server.

  1. FABLEWRIGHT

    Nobody grades their own homework. Claude Fable writes the spec and accepts the result; pinned GPT, DeepSeek and GLM lanes do the work.

    • v1.0.0 released 3 Sep 2026
    • Every model pin proven from its session record
    • 143 offline tests, zero tokens spent

  2. ORRERY

    Architect-first orchestration for coding agents. Your chat keeps the architecture; pinned lanes implement; a read-only reviewer decides.

    • Zero runtime dependencies, 73 offline tests
    • Role files for six clients, from Codex to Kiro
    • The model never chooses where a file is written
