v1.8.1
What's New in v1.8.1
symbi run — Single Agent Execution
Run any agent directly from the CLI without starting the full runtime:
symbi run recon --input '{"target": "10.0.1.5"}'
symbi run assistant -i 'Summarize this document' --max-iterations 5Resolves agent names from agents/ directory, sets up cloud inference from env vars, runs the ORGA loop, and exits.
Usability Fixes
- Auth clarity at startup: Shows which token applies to which port (
Runtime API :8080 (auth: SYMBIONT_API_TOKEN),HTTP Input :8081 (auth: --http.token)) - SYMBIONT_MASTER_KEY warning: Startup warns if missing instead of silently failing
- DSL
#comments: Hash-style comments now supported alongside// - Agent names in API:
GET /api/v1/agentsreturns{id, name, state}instead of bare UUIDs - Multi-agent auto-routing: All loaded agents get
/webhook/<name>routes - Top-level
cedarfeature flag:cargo build --features cedarworks directly - protoc documented: Added to prerequisites in getting-started docs
rust-version = "1.82": MSRV now explicit in Cargo.toml
