Detect stalled automatic history compression so the prompt-prep wait loop cannot spin forever when no further reduction is possible.
Split large manual chat compaction input by verified token budget instead of line midpoint, covering single-line 85k+ character histories.
Add regression tests for stalled compression, max-pass bailout, and large single-line compaction chunking.
Validate and persist API chat lifetime: lifetime_hours is validated as a positive number and stored in the AgentContext data, and context.last_message is set using UTC. Removed the in-class threading-based cleanup state and old _cleanup_expired_chats method. Introduced a new job-loop extension (extensions/python/job_loop/_20_cleanup_expired_api_chats.py) that periodically scans AgentContext instances and removes expired API chats (using persist_chat.remove_chat) in a UTC-aware manner. Added tests (tests/test_api_chat_lifetime.py) to verify lifetime persistence and that the job loop removes expired chats.
Standardize multi-action tools around tool_args.action while keeping parser compatibility for older tool/args, tool_name:action, and method-shaped requests. This keeps new prompts clean without breaking agents that learned the previous dialect.
Move A0 connector remote execution/file tools into stable standard prompts, make remote targeting independent of the active chat context, and skill-gate beta computer-use remote so it no longer weighs down the always-on tool list.
Align text editor, scheduler, skills, office artifact, memory, notify, and browser prompts/tools around the canonical action contract. Add scheduler update/timezone handling, skills_tool read_file, text editor patch coverage, and fixes for memory_forget, behaviour_adjustment, and code execution progress warnings.
Reduce default prompt pressure by compacting browser and scheduler prompts into skill-backed manifests, shortening skill catalog descriptions, and pruning noisy framework knowledge. Remove obsolete connector prompt stubs and root tool-call knowledge examples.

Restyle Settings and standard modals around a streamlined left-rail layout, clearer section hierarchy, advanced settings disclosures, and stronger update states.
Add persistent update visibility with quieter once-daily update notifications, plus Remote Link and Space Agent actions in the canvas rail. Refresh the tunnel experience as a normal Remote Link modal with clearer copy, QR/mobile affordances, and safer state handling.
Add a builtin `a0-setup-cli` skill for guiding host-side A0 connector setup,
and restore the lightweight trigger-word based skill matching flow, which many users asked for.
- add builtin `skills/a0-setup-cli/` with installer-first host setup guidance,
container guardrails, fallback install paths, and example responses
- fix `helpers.skills_cli` so builtin skills under `/skills` are discoverable,
searchable, and validatable
- restore trigger-pattern scoring in runtime `search_skills()`
- re-enable `skills_tool:search` in the current tool flow
- add lightweight lexical relevant-skill recall for the current user message
without reintroducing memory/vector-db skill recall
- update skill prompts to steer the agent toward search/load when requests
match skill trigger phrases
- Refactor API key management: move from global env-only to per-model config with dotenv fallback
- Add API key placeholder masking and reveal functionality in WebUI
- Consolidate API key validation logic into `has_provider_api_key()` helper
- Improve update system: add branch filtering for tags, simplify backup naming
- Add branch detection to version info and default to current branch for updates
- Extract configure model settings link to constant
- Change @extensible decorator to generate extension paths from full module and qualname hierarchies instead of flattened names
- Update extension path format from `{module}_{qualname}_{start|end}` to `_functions/<module>/<qualname>/{start|end}`
- Move all extension files to new deep directory structure under `_functions/` to match new path format
- Replace PathSpec.from_lines(GitWildMatchPattern, ...) with PathSpec.from_lines
- Rename /state_sync namespace to /webui throughout codebase

- Add validate_event_type() class method for runtime event name validation
- Update UserMessage instantiation to use keyword arguments (message=, attachments=)
- Move send_data
- split monolithic _10_system_prompt.py into focused extensions: main (10), tools (11), mcp (12), skills (13), secrets (13), project (14)
- each extension exposes a build_prompt() function with call_extensions_async hook for plugin extensibility
- move tool prompt collection from VariablesPlugin to _11_tools_prompt using subagents.get_paths for proper directory coverage
- add {{include original}} directive to process_includes allowing prompt inheritance without copy-paste
- add agent.system.main.specifics.md for subagent-specific additions without overriding entire role
- remove redundant plugin prompt extensions (_15_text_editor, _20_code_execution) that duplicated tool collection
- add _09_text_editor_config to register per-file kwargs via agent.data instead of VariablesPlugin in prompts dir
- Move allow_chat_override from chat_model to top-level configuration
- Update all references to use new config path
- Set default to true in default_config.yaml, false in migration
- Fix datetime parsing to handle timezone-less ISO strings by appending 'Z'
- Remove inline style from tune icon in config.html
- Add `watchdog` dependency to requirements.txt
- Implement cache entry timestamps with `CacheEntry` dataclass for LRU-style tracking
- Add `trim_cache` function to remove stale entries based on age
- Update cache operations to track and update entry timestamps on access

- Register watchdogs for API handlers, extensions, and plugins to
- Extract presets into global presets.yaml; move editor to plugin main screen
- Add project-wide override sync and three-layer permission checks
- Fix embedding change detection, new-chat inheritance, and preset name leak bugs
- Clean up dead imports/params and fix description text
Redesign extension handling to support explicit async/sync execution. helpers/extension.py rewrites the extensible decorator, adds call_extensions_async / call_extensions_sync, and a helper to gather extension classes; caching flag adjusted. Updated call sites across the codebase (agent, APIs, plugins, tools, settings, extensions) to use extension.extensible and the new call_extensions_async/sync API, and converted several extension handlers from async to sync. Also small frontend tweaks (use globalThis.runtimeInfo) and minor import updates (csrf_protect in run_ui). This centralizes extension discovery/execution and avoids previously scattered asyncio.run usage.
