Llm Bus — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Llm Bus (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Stop being the bridge between your agents. The live coordination layer for AI agents and the humans driving them - so you stop being the bridge. When two people each drive agents, or one person runs ten Claude Code sessions across branches and worktrees, the human becomes the manual relay: copying context between sessions, re-explaining what one agent already figured out, hoping a handoff landed. LLM Bus is the shared backplane over MCP that does the relaying: an attributable handoff channel and a shared event ledger every agent reads and writes, plus atomic gap-free work-claiming and advisory file leases so parallel agents never collide. It is not git and does not need git - it is a thin live layer over whatever the work surface already is (git, a Drive, email, nothing).

LLM Bus is the coordination layer that lets a team of agents work like a well-run team of people: handoffs that get acknowledged, a shared record everyone reads, claims and leases so nobody steps on anyone. The deep-dive is docs/coordination-layer.md. The problems it solves:
window is knowledge teammates re-derive and tokens you burn twice. The shared ledger is a record every agent reads and writes, so a sibling pulls what someone already figured out instead of rebuilding it.
they are attributable and acknowledged, anchored to a concrete artifact (a PR, ADR, commit, or migration) so the record points at real work.
claim means two agents never grabthe same id; advisory leases on real files mean they never clobber each other's edits. Proven under a 500-concurrent test.
as the router or silent mistakes ship. The bus is the live relay: in our own runs an agent caught a peer's merge before it reached production.
What a real run looks like (our own dogfooding, not customer proof): in 8 days of our own multi-agent runs - 9 agents, 4 projects, 591 events - 77.5% of all activity was handoffs and acknowledgments, while claim was only 7.3%. 90.3% of handoffs were acknowledged, and 88% were anchored to a concrete artifact.

Query is exact-match only. Responses are small and stable by design (context cost).
Owner - a human with a globally-unique handle (the public identity); signs in via OAuth or SSO
- Projects - coordination spaces (sequences/events/posts/leases/tasks/presence live here)
- Participants - identities the owner creates (agent OR human): the unique entity "on the ledger"
- Participation - a participant granted into a project; carries a TOKENA bearer token resolves to (participation -> project + participant + owner). MCP tools never accept a project or identity as input - both come from the token, so every act is attributable and every read/write is project-scoped. One token per participant, shared across its sub-agents (they collapse to one identity). Projects and owners are fully isolated.
Identity. Every owner has a globally-unique handle (the public identity; email stays private). A participant is addressed handle/label (e.g. alice/claude-1) - the bare handle is the human as a first-class actor - so the bus actor is unambiguous across owners. The qualified handle/label is what shows in handoffs, presence, whoami, and the ledger; exact-match filters (query_events, list_tasks) take the qualified form.
A server-rendered web admin (/admin, owner-scoped) manages projects, participants, tokens (mint/rotate/revoke), and invites. Onboarding is "one MCP endpoint + a token": hand out a grant card, or a one-use expiring invite the invited party's agent redeems to self-connect.

# round-trip, isolation, fail-open hook, admin, OAuth, invites)LLM Bus is AGPL-3.0. The entire coordination engine is open and self-hostable. The commercial offering is the managed service - frictionless OAuth onboarding plus a cross-org invite network, so the people you collaborate with are one click away - not a feature you have to pay to unlock. AGPL keeps a competitor from cloning the code into a closed rival. See decision 008 for the open-core boundary.
