# GARC ingress.sh — Queue/ingress system (Claude Code execution bridge)
#
# Flow:
#   enqueue → list → run-once → [execute-stub → Claude reads prompt] → done/fail
#
# Claude Code is the execution engine. run-once outputs a structured prompt
# that Claude Code reads and acts on — no external agent process needed.

Usage: garc ingress <subcommand> [options]

Subcommands:
  enqueue       --text "<msg>" [--source gmail|manual] [--sender <email>] [--agent <id>]
  list          [--agent <id>] [--status pending|done|failed|all]
  next          [--agent <id>]
  run-once      [--agent <id>] [--dry-run]   Run next pending item (outputs Claude prompt)
  execute-stub  --queue-id <id>              Show execution plan for a queue item
  context       --queue-id <id>              Output full Claude-readable context bundle
  approve       --queue-id <id>              Unblock an approval-gated item
  resume        --queue-id <id>              Resume a blocked item
  delegate      --queue-id <id> --to <agent>  Reassign to another agent
  handoff       --queue-id <id>             Handoff with full context (for multi-agent)
  done          --queue-id <id> [--note <text>]
  fail          --queue-id <id> [--note <text>]
  verify        --queue-id <id>             Verify expected output was produced
  stats                                      Queue statistics

Examples:
