delivery-chain is a Claude Code plugin, not an app — no GUI, no server, no CLI binary. The deliverable is prose (skills + agent personas under .claude/). The one executable component is the stdlib-only Python agent-memory hook sidecar (scripts/agent_memory_hook.py), invoked by the harness at SubagentStart (inject per-role memory) and SubagentStop/Stop (persist an episode). "Running" this plugin means driving that sidecar the way hooks/hooks.json does, and keeping the Python test suite green.

Drive it via .claude/skills/run-delivery-chain/driver.sh — it feeds the shipped hook command a live-harness event on stdin and asserts the full persist → inject round-trip. There is nothing to screenshot.

All paths below are relative to the repo root (<unit>/).

Prerequisites

python3 (stdlib only — no pip, no venv, no network). Verified on 3.14, the sidecar targets 3.x broadly.
