First stable release of Shannon — a Claude Code plugin for high-stakes multi-stage agentic work.

Surface: 33 skills · 9 agents · 20 commands · 7 hooks.

Five pillars:

  1. Embedded sub-agent skills — sub-agents carry their skills inline; spawning never silently fails to load.
  2. Orchestration — single-message multi-Task dispatch (sequential / parallel / competitive), with escalation to Dynamic Workflows for unbounded fan-out.
  3. Iron Rule validation — real-system evidence on disk. No mocks, no stubs, no test files.
  4. Meta-judge consensus — rubric YAML generated before any judge runs; hidden thresholds; debate on disagreement.
  5. Self-instrumented — scripts/doctor.py (10/10 contract checks) and scripts/harness/load_check.py (real Agent SDK load probe, inherits CLI auth).

Verified at release: doctor 10/10 PASS; SDK load probe PASS (all 20 commands addressable when the plugin loads).
