Agent Workflow 0.3.1

Workers can now activate explicitly selected skills through genuine native Codex skills.list and skills.read tools. Detached workflows also have a durable, session-bound JSONL watcher, so an attached coordinator can receive worker/run terminal records, resume from a saved cursor, and notice missing command or file progress.

The missed layout failure came from detached execution without a standing observer. This release adds durable observation, explicit observer ownership in the workflow skills, and early artifact checkpoints. The original layout worker remains an unknown timeout with an empty capture; its internal stall cause is unconfirmed. See the root-cause report.

• Immutable startup capability bundles select original skill resources and required managed tools. Tool-dependent workers check actual command readiness before inference.
• The workflow authoring skill explicitly maps every worker to selected skills and required tools before startup, including an explicit none where appropriate.
• Public doctor diagnostics report bounded admission stages and cleanup evidence. Failed and interrupted turns retain available command-status evidence without treating partial history as complete.
• Isolation, capture/replay integrity, owned-process cleanup, and unknown outcomes remain fail-closed. Existing runtimes and saved runs are preserved.

Validation: 409 local tests passed; protected Windows PR and release-tag verification passed test/check/smoke, clean-package installation and dependency audit. Marketplace and the installed package select this exact release. Installed command-only doctor passed with zero inference requests; a fresh three-worker native acceptance run completed with positive owned-job/native-inventory cleanup and an attached watcher through terminal cursor 4. Browser checks passed across eight phone/desktop/theme/zoom-equivalent views with no page errors. Sanitized installed verification reports are attached.

One paired read-only planning comparison produced correct routes in both variants. Selected guidance added concrete handoff and recovery details, while taking 2.93× the time and 2.31× the reported total tokens (including cached input); no general improvement claim is made.

Live skill grants are unsupported by pinned native Codex 0.162.1 and are outside this release, per owner scope. The watcher requires an attached host consumer; it does not create automatic native parent-chat notifications. This release does not claim fresh sprite-export, WAV-render/listening acceptance, or a fix for the separate host's unconfirmed Windows command-admission failure.

The three new dashboard layout proposals are available on Sites. They are review options, not a selected production dashboard redesign.
