MetaCrate grid agent
This package is the bounded, provider-neutral foundation for the MetaCrate
OpenSim grid agent. It contains a reusable library and the
metacrate-grid-agent service binary. The default service graph is deliberately
offline: it publishes a deterministic ready event, accepts control commands,
and shuts down both owned tasks without contacting a grid or LLM. The library
also provides the bounded exact-endpoint LLM transport and tool loop for live
adapters. The live-grid feature exposes the side-effect-free owner for the existing
libremetaverse::GridClient; later live adapters must extend that manager graph
instead of adding a protocol client.
The LLM connection identity has exactly two resolved fields:
llm.endpoint_url and llm.api_key. The endpoint is used exactly as supplied;
there are no providers, presets, base-URL rewrites, model catalogs, discovery,
or provider SDKs. Debug/Display output removes API keys, grid passwords, URL
user information, and URL query values. Secret wrappers are not serializable.
Configuration precedence, from lowest to highest, is built-in defaults, an
optional JSON file, its referenced secret files, then environment values (an
environment-referenced secret file is below a direct environment secret).
Supported secret environment variables are
METACRATE_AGENT_LLM_API_KEY[_FILE] and
METACRATE_AGENT_GRID_PASSWORD[_FILE]. Secret files must be bounded regular,
non-symlink UTF-8 files containing one line. Operators must restrict their OS
ACLs to the service identity; the core uses only portable std::fs checks and
does not assume Unix permission bits.
Run the focused offline gate with:
cargo test --locked -p metacrate-grid-agent
cargo clippy --locked -p metacrate-grid-agent --all-targets -- -D warnings
cargo run --locked -p metacrate-grid-agent -- \
--config config/grid-agent.example.json --check-config
cargo run --locked -p metacrate-grid-agent -- \
--config config/grid-agent.example.json --run-once
See ../../docs/grid-agent-architecture.md
for queue/task ownership, shutdown, and trust boundaries. See
../../docs/grid-agent-llm.md for the LLM wire
compatibility envelope, retry rules, and tool-loop safety contract. The central
origin matrix, approval binding, budgets, prompt-data boundary, and opaque
backend authorization are specified in
../../docs/grid-agent-policy.md.
