Modules

acceptance

Phase 67.5 — AcceptanceEvaluator and friends.

attempt

Per-turn loop. Owns the spawned claude subprocess for one turn, projects events back to the orchestrator, and synthesises an AttemptResult at the end.

compact_store

Phase 77.3 — CompactSummaryStore implementations.

config

Driver runtime configuration. The full YAML at config/driver/claude.yaml deserialises into DriverConfig.

error

evaluators

Phase 87.1 — LLM-as-judge AcceptanceEvaluator implementations.

events

DriverEvent enum + sink trait. Subjects when wired to NATS: agent.driver.{goal,attempt}.{started,completed}, agent.driver.{decision,acceptance,budget.exhausted,escalate}.

extract_memories

Phase 77.5 — post-turn LLM memory extraction.

extract_memories_prompt

Phase 77.5 — extraction prompt constants.

harness

ClaudeHarness — closes the AgentHarness contract from 67.0 by delegating to attempt::run_attempt.

llm_decider

LlmDecider — production PermissionDecider that consults a LlmClient (typically MiniMax). 67.4 wires this; 67.7 will plug a real DecisionMemory for semantic recall.

mcp_config

Generate the .nexo-mcp.json Claude reads via --mcp-config.

memory

Phase 67.4 + 67.7 — DecisionMemory trait and impls.

orchestrator

Goal-level loop. Takes a Goal, drives it to completion through the per-turn attempt loop. Emits NATS events at every major transition.

post_compact_cleanup

Phase 77.3 — PostCompactCleanup.

proactive

prompt

Compose the prompt fed to Claude per turn.

replay

Phase 67.8 — replay-policy. Classifies mid-turn errors observed by attempt::run_attempt into a ReplayDecision the orchestrator acts on (mark_invalid, rollback, bump consecutive_errors).

socket

Daemon-side Unix socket server. Bins spawned by Claude (SocketDecider in nexo-driver-permission) connect here and forward each permission_prompt request to the in-process decider.

workspace

Goal workspace management. Phase 67.6 added git-worktree mode on top of the 67.4 mkdir + traversal-guard surface.
