Address the review bot's five genuinely-new findings on the current code: - disposal now discards any still-pending inbox items before the loop exits, so every enqueued id gets a terminal lifecycle event. - injection (next-step/no-wakeup) validates its payload up front, before opening the idle one-shot turn, honoring 'invalid input throws before any append'; and rejects attached contexts (which belong only to inbox messages) rather than silently dropping them. - agentMessage() freezes the agent/inbox/* payload so a listener cannot mutate the shared correlation object mid-dispatch. - refresh the package READMEs (compact, goal, guard, hook-protocol, plan-mode, time-context, workspace-context) that still referenced the removed context/message event, with the source-based user/message distinction. The up-front injection validation makes two finally branches unreachable (v8-ignored as the turn-enclosure backstop). Adds regression tests for disposal discard, context rejection, up-front validation, and the frozen payload; per-file coverage stays 100%.
core/ — product API spine
The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.
| Package | Role | ctx key |
|---|---|---|
scope/ |
Scoped-context registration primitive (scope tags, scope-filtered dispatch) | (library — no ctx key) |
session/ |
Event-sourced session log + in-memory store | ctx.sessions |
system-prompt/ |
Prompt-section + tool-schema assembly registry | ctx.systemPrompt |
tools/ |
Scoped tool registry + pre-policy, guards, around-dispatch, post-policy, and final-result observation | ctx.tools |
agent/ |
Agent interface, live registry, process-local initiator scope, agent/* event vocabulary |
ctx.agents |
agent-loop/ |
Concrete plugin implementing the public Agent contract and owning the loop driver |
ctx.agentLoop |
scope/ is the one non-service package here: a dependency-free library (createScope/scopeOf/scopeTarget) the registries and the loop build per-agent scoping on — it sits below session/ and system-prompt/ in the module graph precisely so they can consume it without a cycle.
agent-loop is the one concrete implementation of the agent seam and lives here because it is the harness's default product loop. It runs each driver inside ctx.agents.withInitiator(). Extension plugins depend on agent, including when they need the initiating Agent, and never on agent-loop directly, so the loop stays swappable.
The default composition that wires this spine into a runnable agent lives in examples/agent-spine-demo: one bundle plugin that loads the control spine plus selected default capabilities (timer + llm + sessions + fallback session titles + system-prompt + tools + agents + invariants + the local skill family + tool-bash + workspace-context + agent-loop) and forwards agent-loop's agents list as its own config. It sits in examples/ — ready-to-run demo/reference bundles — not in core/: core/ ships the swappable spine pieces, while a demo bundle picks one concrete composition of them and adds a front door.
