Highlights
- Adds the shared checkpoint heartbeat and instruction-following Canary across OpenCode, Codex, Claude Code, Hermes, and standalone Claude Desktop.
- Reports input-only capacity telemetry with complete cache accounting, a common 372k operational boundary, and soft 220k/272k planning signals.
- Expands the live watcher and inspector with parent/subagent identity, lifecycle state, current work, input usage, and explicit completion.
- Makes interrupted-agent recovery executable through checkpoint logs and smaller fresh work packages.
- Tightens planning and review around smallest-sufficient scope, bounded remediation, and on-demand artifacts.
- Prominently documents harness capabilities, setup paths, and host-specific boundaries.
Upgrade
Stop active checkpoint watchers and harness sessions, run ./install.sh, then restart the enabled harnesses. Existing JSONL logs remain readable; historical context_used values are not rewritten.
