- /config/agent.yaml and /config/boot.yaml replace the JSON files, read
with serde_yaml_ng (also in the agent, inside WASM).
- sausage init asks nothing and reads no SAUSAGE_* variables. It writes
commented templates with an example for each API, and prints the path
to edit. Until the agent is configured, agent.chat names the missing
field. allow_no_token: true permits a local model without a key.
- The agent speaks openai-chat-completions, the format of OpenRouter,
Ollama, and most providers. base_url follows each SDK: with /v1 for
the OpenAI shapes, without it for Anthropic.
- Checked against the proxy with glm-5.3-flash: the agent wrote, built,
and activated a counter plugin in 55 s.
mold applies to the host target only, in the dev shell, the crane builds,
and the packaged binary (proc macros and build scripts of plugins). A
rebuild of the host test binary after a change takes 0.9 s (15 s with
GNU ld). Measured LTO: no gain worth 4 more minutes per release build.
- The cargo target folder is <cache>/cargo-target, next to Wasmtime's
cache, which moves to <cache>/wasmtime: Wasmtime's cleanup worker
deletes unknown entries in its folder, also Cargo's artifacts.
- Builds use the SDK at <cache>/sdk/<content hash>/, so cargo reuses
the compiled SDK in every world. /plugins/cargo/sdk/ stays for agents.
- Tests run in the release profile and share compiled crates with the
release build.
- The cargo and cli tests use a persistent cache in CARGO_TARGET_TMPDIR:
warm, the cargo suite takes 11 s (was 235 s) and the cli suite 6 s
(was 149 s).
- nix flake check runs ignored stress tests. AGENTS.md: rules for fast
tests.
Activation path (review T6R): a broken plugin or a stray file in
/plugins blocks no activation; candidates replace their own entries;
discovery has a 10 s deadline and its process is stopped after the
answer; an unchanged hash keeps plugin.prev.wasm; activations run in
their own task; the watcher is not recursive; no duplicate services;
rpc.retired waits for live processes of its version; reads and hashes
on blocking threads.
Guest I/O and per-call paths: a stdin write error is EOF, stdout and
stderr are drained before the status; stderr is lossy UTF-8 and goes
to the journal from its own reader; compiled components are freed;
shutdown starts no new processes; lock queues drop stopping processes;
compile before the admission gate; CommandPre per component;
core.unlock in order; null errors are successes; the journal thread
survives SQLite errors.
sausage init builds the agent with cargo.build; sausage without a
command creates ./world. The console reads plain lines without a
terminal. PROTOCOL.md and DECISIONS.md describe the decided rules. The
flake tests the whole workspace and checks the packaged cargo.build.
Staging every write until close broke tempfile, git, and SQLite, which
expect normal files. Actors that need an atomic publish write a temporary
file and rename it; the SDK has write_atomic for that.
Host:
- test first: a new version is tested where it lies; only an installed
version goes to versions/, and instances run from there
- data/ and public/ are shared by all versions; no snapshots; rollback
restores code only
- no re-delivery, status.json, list, remove/archive, smoke test, data/
hiding, or stdin timeout; rollback needs a version
- supervisor.rs split out; one place for installing a version
- init only writes the agent folder; run installs it like any actor
- console: @actor, text to the agent, /help, /quit
Agent:
- every text goes out as a broadcast; 5-line prompt; 5 tools that describe
themselves; turn.json only marks an active turn
Docs: PROTOCOL.md, README.md, DECISIONS.md, AGENTS.md rewritten.
Examples: only notes and notes-v2.
Imported from the spike branch, with:
- a library crate (Host API) for the CLI and the tests
- JSON test scenarios for candidates
- commit on close only for new or truncated files
- a Nix flake: nix run -- init, nix run -- run
