+ +
+``` +- Store Registration: Use createStore from /js/AlpineStore.js. +- Modals: Use openModal(path) and closeModal() from /js/modals.js. + +### Plugin Architecture +- Location: Always develop new plugins in usr/plugins/. +- Manifest: Every plugin requires a plugin.yaml with name, description, version, and optionally settings_sections, per_project_config, per_agent_config, and always_enabled. +- Discovery: Conventions based on folder names (api/, tools/, webui/, extensions/). +- Settings: Use get_plugin_config(plugin_name, agent=agent) to retrieve settings. Plugins can expose a UI for settings via webui/config.html. For plugins wrapping core settings, set $store.pluginSettings.saveMode = 'core' in x-init. +- Activation: Global and scoped activation rules are stored as .toggle-1 (ON) and .toggle-0 (OFF). Scoped rules are handled via the plugin "Switch" modal. + +### Lifecycle Synchronization +| Action | Backend Extension | Frontend Lifecycle | +|---|---|---| +| Initialization | agent_init | init() in Store | +| Mounting | N/A | x-create directive | +| Processing | monologue_start/end | UI loading state | +| Cleanup | context_deleted | x-destroy directive | + +--- + +## Safety and Permissions + +### Allowed Without Asking +- Read any file in the repository. +- Update code files in usr/. + +### Ask Before Executing +- pip install (new dependencies). +- Deleting core files outside of usr/ or tmp/. +- Modifying agent.py or initialize.py. +- Making git commits or pushes. + +### Never Do +- Commit, hardcode or leak secrets or .env files. +- Bypass CSRF or authentication checks. +- Hardcode API keys. + +--- + +## Code Examples + +### API Handler (Good) +```python +from backend.utils.api import ApiHandler, Request, Response + +class MyHandler(ApiHandler): + async def process(self, input: dict, request: Request) -> dict | Response: + # Business logic here + return {"ok": True, "data": "result"} +``` + +### Alpine Store (Good) +```javascript +import { createStore } from "/js/AlpineStore.js"; + +export const store = createStore("myStore", { + items: [], + init() { /* global setup */ }, + onOpen() { /* mount setup */ }, + cleanup() { /* unmount cleanup */ } +}); +``` + +### Tool Definition (Good) +```python +from backend.utils.tool import Tool, ToolResult + +class MyTool(Tool): + async def execute(self, arg1: str): + # Tool logic + return ToolResult("Success") +``` + +--- + +## Troubleshooting + +### Dependency Conflicts +If pip install fails, try running in a clean virtual environment: +```bash +python -m venv .venv +source .venv/bin/activate +pip install -r requirements.txt +pip install -r requirements2.txt +``` + +### WebSocket Connection Failures +- Check if X-CSRF-Token is being sent. +- Ensure the runtime ID in the session matches the current server instance. + +--- + +*Last updated: 2026-02-22* +*Maintained by: Ctx AI Core Team* diff --git a/CODE_OF_CONDUCT.md b/CODE_OF_CONDUCT.md deleted file mode 100644 index 0df9c715..00000000 --- a/CODE_OF_CONDUCT.md +++ /dev/null @@ -1,23 +0,0 @@ -# Contributor Covenant Code of Conduct - -## Our Pledge - -In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation. - -## Our Standards - -Examples of behavior that contributes to creating a positive environment include: - -* Using welcoming and inclusive language -* Being respectful of differing viewpoints and experiences -* Gracefully accepting constructive criticism -* Focusing on what is best for the community -* Showing empathy towards other community members - -Examples of unacceptable behavior by participants include: - -* The use of sexualized language or imagery and unwelcome sexual attention or advances -* Trolling, insulting/derogatory comments, and personal or political attacks -* Public or private harassment -* Publishing others' private information, such as a physical or electronic address, without explicit permission -* Other conduct which could reasonably be considered inappropriate in a professional setting diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md deleted file mode 100644 index 294db34c..00000000 --- a/CONTRIBUTING.md +++ /dev/null @@ -1,23 +0,0 @@ -# Contributing to Project Name - -First off, thanks for taking the time to contribute! - -## How to Contribute - -### Reporting Bugs -If you find a bug, please create an issue on GitHub with a clear description and steps to reproduce. - -### Suggesting Enhancements -If you have an idea for a new feature or improvement, please open an issue to discuss it. - -### Pull Requests -1.
