s01 — The Agent Loop
while True + stop_reason“An agent is just while True + stop_reason.”
Establish the loop before adding I/O. messages[] is the state; stop_reason decides tool use vs. end turn.

Ten progressive sections — the agent loop through gateway routing, heartbeat, delivery, and concurrency. Read each session on Zeus (full markdown below). When a session includes exercises, run the sample code locally alongside the text.

s02 — Tool Use
schema + handler map“Tools are data + a handler map.”
The model names a tool; you dispatch to a registered handler and feed results back into the loop.
s03 — Sessions & Context Guard
JSONL“Sessions are JSONL files.”
Append, replay, and summarize when context grows too large — conversations that survive restarts.
s04 — Channels
InboundMessage“Every platform produces the same InboundMessage.”
Normalize Telegram, Feishu, and friends into one shape before the gateway sees them.
s05 — Gateway & Routing
bindings“(channel, peer) → agent_id; most specific wins.”
Multi-tenant isolation: route inbound events to the right agent instance.
s06 — Intelligence
prompts on disk“Swap files, change personality.”
Soul, memory, skills — layered prompts assembled from files instead of one giant string.
s07 — Heartbeat & Cron
timer + queue“Should I run?” alongside user messages.
Proactive agent work: scheduled checks without waiting for chat input.
s08 — Delivery
write-ahead“Write to disk first, then try to send.”
Outbound queues with backoff so messages survive crashes and flaky networks.
s09 — Resilience
rotate / retry“When one call fails, rotate and retry.”
Profile rotation, cooldowns, and fallback chains when APIs misbehave.
s10 — Concurrency
named lanes“Named lanes serialize the chaos.”
FIFO per lane, generation counters, and bounded parallelism without a single global lock.

Capstone
After s01–s10, you have the gateway stack: same loop as Claude Code, plus routing, persistence, delivery, and production concurrency. Combine with the Claude Code track for deep harness skills on the unit agent.
