v3.0.0

Agent Session Kit v3.0.0

Release date: March 14, 2026

Summary

ASK 3.0 is the Session OS release. ASK now uses an event-ledger runtime with replayable snapshots and deterministic
command contracts across planning, execution, coordination, and delivery governance.

Highlights

1. Event-ledger runtime and replay

• Append-only runtime ledger at .ask/runtime/events.ndjson
• Replay-driven snapshots in .ask/runtime/snapshots/*
• ask replay for deterministic state rebuild and recovery

2. Full Session OS command surface

• Session/policy: session, context, preflight, can-commit, pre-commit-check, pre-push-check
• Execution: task, evidence, verify, workflow, integration, integration-auto
• Delivery: feature, release, promote, rollout, rollback

3. Multi-agent coordination

• Routing, claims, child-session, and agent command families
• Queue/policy-pack runtime for execution policy decisions
• Workflow-provider compatibility checks

4. Reliability and autonomy

• Guarded execution with 180s stall timeout + one auto-retry
• ask session doctor runtime diagnostics
• Codex context-budget controls: ask codex context status|ensure|compact
• Autonomous phase verify/ship runners

Verification

• npm run test:release-docs PASS
• npm run test PASS (30/30)
• npm run test:ask-core PASS (68/68)
• node scripts/verifyReleaseDocsConsistency.mjs --root . PASS

Upgrade Notes

• Major release: ASK runtime model is now event-ledger + projection first.
• Re-run installer/hook setup in adopting repos to ensure current runtime adapters.
• docs/session/* remains required operator evidence; runtime truth is reconstructed from ledger + snapshots.
