Restore main.communication, main.solving, main.tips and tool.response, which made the model dumber. For some reasons the drawback was more visible with frontier LLMs.
restore builtin plugins and agent0 profile
Promote the a0_small prompt work into the shipped default stack.
Token count for default prompt, accounting for tools, plugins, secrets placeholders, inactive project, etc: 2996 tokens.
- migrate compact prompt fragments into core prompts, plugin-owned prompts, and the agent0 overlay
- remove the obsolete a0_small profile and rename the tool-call knowledge reference to a generic framework file
- keep a small set of high-value JSON examples while preserving key guardrails for tool names, tool args, and method-style calls
- bake balanced conciseness into default response behavior without changing the initial greeting
- drop the call_sub prompt-side loader and keep call_sub guidance self-contained
- restore essential secrets/security guidance, preserve inactive-project messaging, and rebalance the A2A prompt
- add a regression test that verifies the assembled default agent0 prompt stays under the token budget and retains critical guardrails
- Import secrets helper module
- Increase initial command truncation from 200 to 250 characters
- Add secret masking to format_command_for_output using agent context's secrets manager
- Apply masking before final truncation to prevent secret exposure in logs
- Normalize plugin paths using files.normalize_a0_path in get_enhanced_plugins_list
- Add collapsible README section to plugin info modal with loading/error states
- Implement loadPluginReadme function to fetch and render plugin documentation
- Update plugin hub pagination from 20 to 24 items per page
- Change popular filter threshold from >0 to >=3 stars
- Add comprehensive README styling with support
- 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
- Change X-OpenRouter-Categories from YAML list to comma-separated string
- Add pipx to base Python installation
- Truncate long lines in code execution output to 500 chars (250 from each end) before prompt detection
- Reorder model config UI sections and simplify plugin config button handler
- Remove border/padding from model summary grid and adjust mobile responsive styles
