Keep the valid-tool-root preference added for streamed snapshots, but avoid collecting and re-walking parsed candidates.
Remember the first parsed object/root while scanning and use a small predicate for tool-request recognition.
Keep the malformed SKILL.md warning behavior, but reduce the diagnostic machinery to a once-per-path warning with line numbers only for parser-owned structural errors.
Update the regression to assert the stable warning message without depending on the previous path/line/error dedupe key.
Keep the streaming early-stop caller untouched by making extract_json_root_string prefer the first complete JSON root that normalizes as a tool request while preserving its first-root fallback for non-tool JSON.
Add regression coverage for incidental JSON before a streamed tool-call envelope.
Default empty skills_tool calls to list, accept legacy method as a deprecated action alias, and warn when malformed SKILL.md frontmatter causes a skill to be skipped. Update the helper/tool DOX notes and focused regressions.
Save MCP image and image-resource payloads as scoped artifacts, return their paths in tool text and attachment metadata, and keep them model-visible through raw image history content. This gives downstream media delivery a real file path instead of only an inline data URL.
Treat pre-output Responses API 400 validation failures as unsupported so OpenAI-compatible providers that reject /v1/responses payloads can retry through Chat Completions. Also prefer a valid tool-call JSON object after leading prose or incidental JSON to reduce false misformat warnings.
Add the missing 256x256 thumbnail asset for the built-in What's New plugin. The image is compressed under 20 KB and stored in the plugin web UI asset location used by bundled plugin cards.
Update the docs index, quickstart, and installation guide to present A0 Launcher, A0 Install, and direct Docker as distinct setup paths.
Add the A0 Launcher v0.9 download matrix, document headless installer usage, and align visible architecture labels with the x86/ARM wording.
Move installation guidance out of the feature overview and split it into Launcher, A0 Install, and direct Docker paths.
Add the A0 Launcher v0.9 download matrix, document headless A0 Install usage, and keep the visible architecture labels aligned with the requested x86/ARM wording.
Guard stream reconfiguration so pytest capture objects without reconfigure support can import the code execution TTY helper while preserving UTF-8 error handling for normal streams.
Raise the runtime container soft nofile limit before supervisord starts so WebUI and managed services inherit a larger descriptor allowance.
Add an explicit compose nofile example, document the startup contract, and cover the limit raise and hard-limit cap with focused regression tests.
Add a Launcher guide with runtime setup, Installs, Instances, and screenshot capture notes.
Link the guide from README, quickstart, and docs index, and clarify the v1.20-to-v2.0 image upgrade path with backup/restore screenshots.
Use the same minimal trixie Xpra fallback package set for any architecture when the preferred Xpra repository is unsatisfiable.
This lets amd64 recover from current xpra beta sid libopenjph dependency drift like arm64 already does.
Suppress the chat progress ghost placeholder until a chat is selected so the welcome new-chat prompt remains the only visible composer hint. Add a focused static regression for the welcome composer idle-progress overlap case.
Move the ctx_length control for main and utility model slots above the Advanced disclosure while keeping embeddings excluded. Add a static regression guard so primary context controls stay visible outside Advanced.
Reset inherited mobile white-space inside the chat compaction modal so template indentation does not render as large vertical gaps.
Constrain the custom dialog body and raise the overlay above the mobile canvas rail.
Route the Configure credentials banner link through the welcome banner action dispatcher so it opens Settings directly at External Services > Authentication.\n\nAdd coverage for the unsecured connection banner and document the structured banner action contract for future banner links.
Restore restorable surface modals through the initFw_end extension hook and keep right-canvas state in session storage for normal reloads.
Fix Desktop host visibility after modal cleanup so preserved iframes reattach to real modal or canvas hosts, and remove the duplicate file-browser path icon overlay.
Split the monolithic a0-development skill into a lean entry point plus focused reference files for runtime, DOX, tools, extensions, API/WebUI, profiles, prompts, skills, projects, and plugin workflow.
Update the skill DOX ownership for the new references directory and clarify the root framework-vs-agent Python runtimes plus port-discovery guidance.
Verified with git diff --check, targeted skill/tool tests under PYTHONPATH, and live localhost:32769 skill loading/read_file checks before committing.
Reintroduce the shared .text-button primitive in WebUI button CSS so model-config preset controls no longer depend on the chat composer being mounted first.
Document the shared compact text-action contract and add a focused regression covering Model Presets and Model Configuration text-button usage.
Rename the Gemini OAuth provider surface to Google Cloud Gemini so the OAuth provider list points users toward the required Google Cloud project setup.
Align model-provider metadata, usage-plan copy, README wording, and static assertions while keeping the Gemini API OAuth mechanics unchanged.
Route non-action canvas surfaces to their floating/modal forms while the welcome screen is active, and keep the canvas rail/shell hidden until a chat is selected.
Open the welcome Files quick action through the File Browser modal directly so the first screen remains composed.
Document the welcome/canvas boundary in the local DOX contracts and add focused regression assertions for the canvas guard and Files quick action.
Raise the shared modal stack above the mobile right-canvas rail so blocking modals remain authoritative on small screens. Compact the mobile rail below 420px to reduce intrusion on narrow phones, and document the stacking contract in the owning DOX files.
Verification: pytest tests/test_browser_agent_regressions.py -q; pytest tests/test_office_canvas_setup.py -q; git diff --check; headless Chrome smoke confirmed modal content wins at the rail overlap point.
Store explicitly loaded skill IDs as chat-wide context data while keeping full skill bodies in normal tool-result history. Reattach any loaded skill body that is no longer visible after compaction by reimporting the current skill from its source, without revision hashes or protocol reinjection.
Update compaction and summary prompts to preserve loaded skill names only, refresh DOX contracts, and add focused coverage for context-data persistence, legacy agent-data migration, duplicate suppression, and post-compaction reattachment.
Generalize the Editor storage/session path from Markdown-only to exact-text .md and .txt documents, including open, save, Save As, and rename refresh behavior.
Expose Open in Editor as a visible row action in the File Browser for Editor-owned text files, keep non-Editor surface opens in the overflow menu, and route Desktop text MIME handling through the Editor bridge.
Tests: node --check webui/components/modals/file-browser/file-browser-store.js; python -m py_compile plugins/_office/helpers/document_store.py plugins/_editor/helpers/markdown_sessions.py plugins/_editor/api/editor_session.py plugins/_editor/api/ws_editor.py plugins/_desktop/helpers/desktop_session.py plugins/_desktop/api/desktop_session.py plugins/_office/api/office_session.py plugins/_office/api/ws_office.py; pytest tests/test_office_document_store.py tests/test_file_browser_navigation.py tests/test_office_canvas_setup.py -q
Move Annotate and Browser settings into the Browser toolbar so narrow views keep navigation and controls on one row above a full-width address bar.
Make the Browser panel itself the container-query boundary so mobile modals and narrow right-canvas panels share the same polished toolbar layout, with regression and DOX coverage.
Keep the File Browser path and search affordances on compact mobile rows, with create buttons sharing the search row and the Up control sharing the path row.
Give the Web Browser mobile toolbar a full-width address row by moving navigation controls above it, and add regression/DOX coverage for the layout contracts.
Keep the right-canvas rail visible at mobile widths while routing non-action surface affordances into floating modals instead of the side canvas shell. Hide mobile surface-modal header controls except the close button and Editor New action, and clamp floating surface modal geometry to narrow viewports.
Show the What's New modal once per newer version by default, add a browser-local permanent opt-out checkbox, and expose the modal through the builtin plugin Open action. Keep the legacy modal path as a compatibility redirect and update the local DOX/tests for the new contract.
Match the real chat composer to the welcome composer by using an 8px radius, centering the idle Waiting for input cue and fullscreen input control against the composer container, and switching the fullscreen input icon to the same fullscreen glyph used by modal surface Focus mode. Also remove the mobile-only #chat-input min-height under 640px so the composer can size naturally on narrow screens.
Update the Projects modal card layout so edit/delete and activation controls stay beside the project title on narrow viewports. Add truncation for long project titles and paths, collapse activate/deactivate labels on phones, and preserve desktop spacing while preventing horizontal overflow.
Adjust the welcome-screen composer so the shared chat input wraps cleanly on narrow phones. Reclaim hidden expand-button padding, suppress placeholder-only textarea scrollbars, and tune the iPhone-width placeholder sizing while preserving normal typed-message scrolling.
Route right-canvas rail clicks through the explicit canvas opener so Browser, Editor, Files, and Desktop open in the canvas even after a modal session. Preserve modal-header surface switches as floating modal entry points, and document/test the entry-point split.
Add Files to the universal canvas rail and sidebar flow, with a reusable floating surface modal chrome that matches Browser/Desktop behavior.
Make the File Browser modal draggable/resizable with Focus mode, keep Editor on the same draggable modal helper, and preserve dock/undock handoff state.
Harden File Browser startup so empty paths resolve to the default workdir, restyle the Up control, compact New file/New folder actions, and hide Modified before Name/Size in narrow containers.
Update DOX contracts and focused regression coverage for the new Files surface, modal chrome, default-path fallback, and compact layout behavior.
Introduce generic project edit-data extension hooks so plugins can contribute named project settings sections without coupling helpers.projects to plugin-specific storage.
Move _model_config project LLM payload handling behind those hooks and preserve inherited global model settings unless a project override already exists or is explicitly selected.
Cover the inheritance regression, existing scoped overrides, multiple plugin sections, core-field collision protection, and extension payload filtering in focused project/model-config tests.
Fold the blocking onboarding state into the welcome composer, refresh the account and channel tiles, and keep system resources aligned with the renewed Welcome Screen layout.
Update model-config, OAuth, and welcome static tests to pin the new CTA, dismissal, copy, and layout contracts.
Rework the welcome screen around the shared new-chat composer, renewed quick actions, discovery cards, OAuth accounts, and dedicated system resources panel.
Restore static button colors and neutral surfaces, move microphone state feedback onto the icon, and keep Rubik/code-font composer behavior.
Add focused static regressions for the welcome composer, OAuth discovery panel, and speech button contract.
Use the active settings dictionary when scheduling MCP config updates so applying global MCP servers no longer references an undefined config variable.
Add a focused regression test covering the settings apply path and document the deferred MCP update contract in settings.py DOX.
Introduce an always-enabled _whats_new plugin that shows a version-gated feature showcase modal with bundled media assets for parallel tool calls, the redesigned MCP configuration UI, and Skills Scanner.
Track the plugin in DOX and add static coverage for the modal copy, assets, manifest, and startup trigger.
Use the shared sanitized file writer for chat compaction backup artifacts so JSON and transcript backups remain writable when a long chat contains malformed Unicode such as lone surrogates.
Add a regression that exercises surrogate-containing backup content and document the backup artifact contract in the chat compaction DOX file.
Verified with: conda run -n a0 pytest tests/test_chat_compaction.py -q; python -m py_compile plugins/_chat_compaction/helpers/compactor.py tests/test_chat_compaction.py; live localhost:32080 surrogate-long-chat repro after syncing into /a0 and restarting the container.
Create /a0/usr/uploads during Docker runtime initialization before supervised services start so upload callers can rely on the directory immediately after boot.
Document the startup directory contract in docker/run AGENTS instructions.
Skip persisted tool-result files for BACKGROUND contexts, remove ephemeral direct parallel worker chat folders during cleanup, and ignore chat directories without chat.json during startup loading.
Add focused regressions for background output persistence, parallel worker cleanup, and orphan directory loading.
Prefer vision_load for images, screenshots, scans, charts, photos, and diagrams when vision tools are available.
Keep document_query focused on PDFs, documents, large text-heavy files, code-file Q&A, and fallback OCR when vision cannot read the needed text.
Update bundled prompt, skill guidance, DOX notes, and regression coverage for the routing contract.
Introduce a new prompt "protocol" separate from extras: add LoopData.protocol_temporary and protocol_persistent, include protocol contents before message history during prompt construction, and clear temporary protocol data each turn. Add helper _build_context_message to render protocol/extras, update response input conversion to include protocol, and move project instructions & active/loaded skills injection into protocol. Update docs, prompts, plugin metadata, the SkillsTool message, and add tests to verify protocol placement and behavior.
Release MCP config locks before awaited initialization or tool calls, isolate MCP session operations in disposable DeferredTask workers, and bound session cleanup so wedged transports cannot freeze later agent work.
Add deterministic MCP regression coverage for lock scope, config update initialization, cleanup timeouts, and isolated operation timeouts. Update the helper DOX contract for the new concurrency and cleanup behavior.
