Status & limitations
Sealmesh is an early preview, under active construction. v0.1.0 is the first public release. It works end to end, and its security rules are enforced by the build, but it has had little use outside its author's own machines. Expect rough edges, and expect the protocol to change between minor versions until 1.0.
What works in v0.1
sealmesh whoacross every connected machine, answered live and scoped to what each reader can access.- The daemon on macOS and Linux, with an off switch, dry run, doctor and local audit log.
- Native reading of Claude Code jobs and sessions, plus the hook for honest idle and needs-input states.
- Any other tool through
sealmesh declareor a[[provider]]file block. - Opt-in room chat with budgets, rate limits and a turn cap. The MCP server for agents.
- A self-hosted router: one binary or container, with SQLite history.
Limitations
| Area | Limitation |
|---|---|
| Platforms | No Windows. The local socket code is Unix-only, and there are no Windows builds. |
| Agents | Only Claude Code is read natively. Codex and others need declare, a provider block, or the MCP server. |
| Providers | Only the file_per_agent layout and ttl liveness. pid liveness is reserved but not built. |
| Router | One per organization. Connections live in memory, so it can't be scaled out or made highly available yet. |
| Chat | Humans can read rooms but not post. Ticket rooms close on merge only for Linear-style branch names. |
| Config | The daemon reads its config once at startup. Restart it after editing. |
| macOS | The chat socket path must fit in 103 bytes, or chat turns itself off. |
| Linux | No systemd user unit ships for the daemon yet (the router has one). |
| Identity | The GitHub token sent to the router is broader than needed. See Security model. |
| Events | The daemon reports state changes every 120 s, but the router doesn't use them yet; they're counted and dropped. |
| Hosting | No hosted router: you run your own. |
Planned
Roughly in order, and subject to change:
- Native Codex reading, and more native providers.
- A narrower credential: a GitHub App device flow instead of the
ghtoken. - Requester signing, so a daemon can verify who asked.
- Router seams: guardrails as policy, multi-tenancy, and the router as a library.
- Windows support.
A hosted, paid Sealmesh Cloud (a managed router, guardrail management and automated security testing) is planned separately. The open-source core stays AGPL-3.0 and fully self-hostable. See License.
