Aether Agent v0.3.0

Aether Agent 3.0

Aether Agent 3.0 turns local coding work into a durable, verifiable workflow
that can move between sessions, models, checkouts, and machines without handing
away tool authority.

What changed

• Durable work and handoffs. Resume project sessions, inspect their real
  continuity state, and export bounded continuation records without absolute
  paths, file contents, shell history, or credentials.
• Review to pull request. aether review binds verification to the current
  commit and working tree; aether ship publishes only the reviewed head after
  explicit action approval.
• Skills and capabilities. Six built-in skills ship in the package. Skills
  and AGENTS.md now participate in real runs, and skill policy can only narrow
  the available tool surface.
• Headless execution. aether exec provides versioned JSONL protocols,
  repository-bound checkpoints, acknowledged controls, confined agent
  definitions, receipts, and host-authoritative verification.
• Local Ollama workflow. Setup, diagnosis, model listing, selection, and
  pulls are explicit, namespaced, and consent-gated. A plain npm install can run
  the packaged local brain.
• Managed previews. Preview start, readiness, open, logs, status, and stop
  are owned by a loopback-only supervisor with one-use local control and full
  process-tree cleanup.
• Generated public truth. The command manifest, command reference, model
  catalogue, package inventory, and release claims are checked together.

Security and release hardening

• Local tools remain path-confined and permission-gated.
• Credentials, absolute paths, private memory, and file contents are excluded
  from portable handoffs and support bundles.
• Cancellation and preview stop clean up full process trees without attaching
  to stale or unrelated PIDs.
• CI qualifies Linux, Windows, the packed supply chain, and CodeQL on the exact
  release head.
• The npm workflow rebuilds from the tag, produces a CycloneDX SBOM, attests the
  package, and publishes with provenance through the owner-gated environment.

Install

Requires Node.js 24 or newer.

npm install -g aether-agents@0.3.0 --ignore-scripts
aether --version

Known limitations

• Production Agent DevSessions are currently disabled. Hosted coding and the
  Cloud aether exec driver fail closed instead of degrading into server-side
  chat execution. Local Ollama and model-free self-test paths are available.
• The Aether Online/Code redemption contract is not exposed as a supported
  Agent command in this release.
• /rc remote viewing is not part of v0.3.0; its viewer and device-enrollment
  dependencies remain follow-up work.

Full verification and rollback evidence is recorded in the
v0.3.0 operator packet.
