Four values complete the vocabulary, so the opaque body is reached only by producers that genuinely promise no shape. `snapshot` — current state a later snapshot supersedes. system-prompt now exposes `renderContextSections()`, the named contributions `renderContextSnapshot()` already joins for the model, so the body attributes each part to the subsystem that produced it instead of re-splitting joined prose. The runtime snapshot, time-context, and tmux-context declare it. `notice` — a one-off account of what just happened, declared by tool-tasks, goal state changes, tool-goal wrap-up, plan-mode switches, and repeat-tool-guard. Its `summary` rides the COLLAPSED row: these five are the majority of shipped producers and none of them needs expanding to be read. The task summary bounds itself because its inputs are unbounded caller text. `relay` — a message another agent addressed to this one; both subagent sources declare it and the body names the sender above what it said. `recall` — material lifted from another session's log. session-reference needed no new field: its references already record retained and omitted counts and the truncation flag, which the body shows first, because recalled context is bounded on the way in. `ContextFormed` is now discriminated by `form`, so a producer cannot declare a shape without the facts that shape is presented from — a notice without its summary, or a snapshot without its sections, fails to compile. Only the two hook bridges stay opaque, by design: their content is whatever an external program printed, so no shape can be promised for it. Unknown kinds and unreadable records land there too.
headless-agent
English | 中文
Headless one-shot agent wiring: DeepSeek V4 + local bash and filesystem tools + subagent delegation + workflows and fresh-agent Ralph iteration + todo_write + JSONL persistence, with @deepseek-ai/dsh-cli-demo as the app front door.
Run it
# repo root .env (gitignored) or exported env:
# DEEPSEEK_API_KEY=sk-…
# DEEPSEEK_BASE_URL=https://… # optional; defaults to the public API
pnpm run demo:headless "fix the failing test in this workspace"
pnpm run demo:headless --output-format json -- "summarize the implementation"
pnpm run demo:headless --output-format stream-json -- "run the focused tests"
Exactly one nonblank positional task is required; quote tasks containing spaces. There is no -p flag. text prints the last text-bearing assistant message, json prints one DSH-native result record, and stream-json emits the top-level session's canonical task-turn events before that record. Child sessions surface only through parent tool events and results.
Each invocation creates and persists a fresh session, runs all model and tool steps in one turn, flushes, disposes, and exits. This is non-interactive automation: there is no prompt, approval, resume, second turn, or stdin context. The configured tools can mutate the launch workspace, run commands, spawn child agents, and consume provider tokens.
Advanced and snapshot wiring
advanced.cordis.yml adds Code Mode and the Cordis tools to the shipped leaf. advanced.cordis.snapshot.yml replaces only the live LLM with replay. The tests under tests/ own the keyless real-Loader smoke, key-gated world-verified smoke, and the stream-json replay snapshot with its parent and child session fixtures.
The package-level CLI contract documents output records, exit status, cancellation, persistence, and model/token effects.
