Release cortex-agent server v2026.10.27 · fangxm233/cortex-agent

Highlights

Clean mode: run a session or subagent in its own workspace, without Cortex rules, hooks or project context
The npm server package now ships as smoke-tested, code-split bundles, and local source rebuilds install the same bundled layout
Rewind now cuts the backend transcript back to a recorded anchor instead of restoring full transcript copies
Agent-sent files show up as cards in the transcript
Added Opus 5.5, Sonnet 5.5 and Haiku 5.5 to the shipped Anthropic model list

Added clean mode for sessions: a clean session gets its own folder under workspaces/ (with an inputs/ subfolder) as its working directory, runs without Cortex rules, agent hooks or project context files, and receives turn attachments in inputs/.
Added clean subagents: the agent tool takes clean and files per task; listed files are copied into a fresh workspace's inputs/, and children of a clean session are clean and share its workspace.
Added a clean-mode toggle and workspace chip to the desktop composer and the mobile chat screen, and marked clean subagents in the transcript.
Fixed clean runs so user-authorized external paths are allowed and git status is kept out of clean Claude runs.

Switched the published npm server package to code-split JavaScript bundles with the PI runtime, Web SPA, client bundle, defaults and offline third-party license notices included; CI installs and smoke-tests the exact tarball before publishing.
Made daemon source rebuilds stage and validate a bundle with the release layout, then install it as a whole directory; set CORTEX_REBUILD_BUNDLE=0 in config/.env to fall back to the unbundled build.
Added opt-in JavaScript source maps for local rebuilds.
Made bundle updates restart even when debug cleanup fails, prevented fast source installs over bundled packages, and suppressed postinstall restart triggers on daemon-managed installs.
Made the gateway port and state home configurable per instance, for isolated local gateways.

Switched rewind to recorded transcript anchors: each turn records where it starts in the backend transcript, and a turn that cannot be restored is refused instead of continuing in an empty backend session.
Added a startup migration that converts existing turn backups to anchors and deletes the legacy copies once converted.
Raised the default session retention to 90 days.

Added file cards for files sent by the agent, lined up at one width per message.
Added Stop server to the Daemon sheet and Settings for local desktop installs.
Added cache keep-warm and cold-resume clearing controls to Settings → Advanced.
Added the server version to the About dialog.
Fixed the agent browser tab viewport at 1280×800 per session and drew stream frames without distortion.
Fixed the pinned mobile agent header layout.
