If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/Kuberwastaken/claurst shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Claurst is an open-source, multi-provider terminal coding agent written in Rust that replicates and extends Claude Code's agentic capabilities for local execution. It integrates with 30+ AI providers (Anthropic, OpenAI, Google, Ollama, etc.) via a pluggable provider system, executes tools in a sandboxed terminal, manages conversation state with memory consolidation, and provides a rich TUI built with Ratatui and Crossterm for interactive pair programming. Rust monorepo (src-rust/) with 11 workspace crates: core (agent logic), api (HTTP abstractions), tools (command execution), query (prompt handling), tui (terminal UI with Ratatui), commands (CLI commands), mcp (Model Context Protocol), bridge (CLI/remote communication), cli (entry point), buddy (companion features), plugins (plugin system), acp (provider adapters). State flows from CLI → TUI → Core → API/Tools → Provider SDKs. Configuration stored in TOML, serialized via serde.

Developers who want a locally-hosted, telemetry-free AI coding copilot that works in the terminal; engineers building AI agent systems who need a reference implementation of multi-provider tool-use patterns; Rust developers wanting to understand async TUI applications and streaming API integrations.

v0.0.9 active development — the repo shows consistent recent activity (CI/CD pipelines in .github/workflows/, release binaries distributed, workspace-based monorepo structure). Core features are functional (managed agents, multi-provider support, plugins), but experimental features are marked as such. Not yet 1.0, so expect breaking changes; however, the codebase is production-capable for local use.

Single maintainer (Kuberwastaken) creates vendor lock-in risk. Large dependency footprint (tokio, reqwest, ratatui, syntect, rusqlite) means supply-chain exposure. The crates/acp (Anthropic provider abstraction) and crates/mcp (Model Context Protocol) are tightly coupled, making provider swaps potentially fragile. No visible test suite in the file structure (critical gap for a tool that executes arbitrary shell commands).

Managed Agents system recently added (Manager-Executor agentic loop with 6 pre-built templates). Speech modes are experimental (/rocky, /caveman, /normal). Multi-provider support expanded (visible in docs/providers.md). Voice/microphone features can be disabled at build time. Binary releases are active across 5 platforms (Windows, Linux x86_64/aarch64, macOS Intel/Silicon). GitHub Pages deployment configured.

• src-rust/crates/cli/src/main.rs — Primary entry point for the terminal agent; initializes the CLI, handles user input, and orchestrates the main event loop.
• src-rust/crates/api/src/lib.rs — Core API abstraction layer exposing provider registry, message normalization, and multi-provider request handling—essential for understanding how different LLM providers are unified.
• src-rust/crates/api/src/providers/mod.rs — Provider trait and module organization; defines the interface all LLM providers (Anthropic, OpenAI, Azure, etc.) must implement.
• src-rust/crates/core/src/analytics.rs — Core state and context management for agent sessions; tracks messages, permissions, and execution context throughout the agent's lifecycle.
• src-rust/Cargo.toml — Workspace root configuration defining all crates, versions, and shared dependencies—required reading for build configuration and dependency resolution.
• src-rust/crates/commands/src/lib.rs — Command execution layer that bridges user input to agent actions; critical for understanding how terminal commands are parsed and executed.
• src-rust/crates/bridge/src/lib.rs — Bridge module for CLI-to-remote communication; essential for understanding distributed execution and multi-machine agent support.

Add a New LLM Provider

1. Create a new provider module in src-rust/crates/api/src/providers/ with your provider name (e.g., mistral.rs) (src-rust/crates/api/src/providers/mistral.rs)
2. Implement the Provider trait defined in src-rust/crates/api/src/provider.rs, including send_message(), send_message_stream(), and configuration methods (src-rust/crates/api/src/provider.rs)
3. Register your provider in the module registry by adding a public use statement and match arm in the factory function (src-rust/crates/api/src/providers/mod.rs)
4. Create type definitions for your provider's request/response in src-rust/crates/api/src/provider_types.rs or add variants to existing enums (src-rust/crates/api/src/provider_types.rs)
5. Add a transformer in src-rust/crates/api/src/transformers/ if your provider uses a unique message format not compatible with existing transformers (src-rust/crates/api/src/transformers/mod.rs)
6. Register models for your provider in src-rust/crates/api/src/model_registry.rs with appropriate capability metadata (src-rust/crates/api/src/model_registry.rs)
7. Update OAuth flow in src-rust/crates/cli/src/oauth_flow.rs to handle your provider's authentication if required (src-rust/crates/cli/src/oauth_flow.rs)

Add a New Terminal Command

1. Define your command structure and handler in src-rust/crates/commands/src/named_commands.rs following the existing command patterns (src-rust/crates/commands/src/named_commands.rs)
2. Register the command in the command dispatcher within src-rust/crates/commands/src/lib.rs to make it available to the agent (src-rust/crates/commands/src/lib.rs)
3. Add command documentation in the system prompt at src-rust/crates/cli/src/system_prompt.txt so the agent knows how to invoke it (src-rust/crates/cli/src/system_prompt.txt)

Add Support for a New Provider Authentication Method

1. Implement authentication logic in src-rust/crates/api/src/auth.rs as a new variant or handler method (src-rust/crates/api/src/auth.rs)
2. Create provider-specific OAuth or credential flow in src-rust/crates/cli/src/oauth_flow.rs (or specialized file like codex_oauth_flow.rs for complex flows) (src-rust/crates/cli/src/oauth_flow.rs)
3. Update the provider implementation in src-rust/crates/api/src/providers/[provider_name].rs to use the new auth method in request headers/body (src-rust/crates/api/src/providers/anthropic.rs)

Extend Agent Capabilities with a New Tool

1. Define the tool handler in src-rust/crates/commands/src/named_commands.rs or create a new module under src-rust/crates/commands/src/ (src-rust/crates/commands/src/named_commands.rs)
2. Register the tool in the command dispatcher in src-rust/crates/commands/src/lib.rs so it can be invoked by the agent (src-rust/crates/commands/src/lib.rs)
3. Document the tool in the system prompt at src-rust/crates/cli/src/system_prompt.txt to enable agent self-instruction (src-rust/crates/cli/src/system_prompt.txt)
4. Update agent state tracking in src-rust/crates/core/src/analytics.rs if the tool modifies session state or requires permission tracking (src-rust/crates/core/src/analytics.rs)

No test suite visible: Critical for a tool executing arbitrary shell commands — test coverage unknown. Voice/Audio feature flag: Default build includes microphone support (requires libasound2-dev on Linux); omit with --no-default-features. Database schema migration: rusqlite uses bundled SQLite but no migration system visible — check crates/tools/src/ for schema initialization. MCP version pinning: crates/mcp/ couples to a specific Model Context Protocol version; updating providers may require MCP changes. Config file location: Likely in ~/.config/claurst/ or platform-specific via dirs crate, but not explicitly documented in visible files. Streaming response parsing: Provider SDKs vary widely in streaming format (SSE, JSONL, newline-delimited); integration points are in crates/api/src/providers/ and may have undocumented edge cases.

• Multi-Provider Abstraction Pattern (Strategy + Factory) — Claurst supports 30+ AI providers via a trait-based abstraction in crates/api/src/provider.rs; understanding this pattern is essential for adding new providers or modifying existing ones without touching core agent logic
• Streaming JSON/SSE Parsing (async_stream, futures::stream) — AI providers stream tokens incrementally; Claurst uses async-stream and futures to parse incomplete JSON and newline-delimited events without buffering entire responses
• Tool-Using Agentic Loop (ReAct / Function Calling) — Core behavior in crates/core/src/agent.rs: agent generates tool calls, executor runs them, results feed back into prompt — fundamental to AI coding agents
• Terminal UI State Machine (Ratatui + Crossterm) — TUI manages input events, viewport scrolling, conversation rendering; crates/tui/src/state.rs implements a reduction-like pattern for terminal applications
• Model Context Protocol (MCP) — Standardized way to define tools/resources for AI models; Claurst implements MCP in crates/mcp/src/ to enable structured tool discovery and execution
• Subprocess Signal Handling (nix crate, POSIX signals) — Tools are executed as child processes; crates/tools/src/executor.rs must handle SIGTERM/SIGKILL for graceful cancellation — critical for user control and resource cleanup
• Workspace Monorepo with feature flags — 11 crates in src-rust/ with shared dependencies; build system uses Cargo features (e.g., --no-default-features disables voice). Dependency resolution and feature propagation can create subtle bugs

• anthropics/anthropic-sdk-python — Official Anthropic SDK that Claurst wraps; reference for streaming API behavior and tool-calling protocol
• continuedev/continue — Similar multi-provider coding agent (Python/TypeScript-based) with IDE integrations; shares architectural patterns for tool management and provider abstraction
• aider/aider — Alternative terminal coding agent (Python); architectural peer for comparison on tool execution, conversation management, and multi-file editing
• modelcontextprotocol/specification — MCP specification that Claurst implements in crates/mcp/; authoritative reference for tool definition and resource protocol
• ratatui-org/ratatui — TUI framework Claurst depends on; understanding Ratatui internals essential for debugging rendering and event handling in crates/tui/

Add integration tests for multi-provider authentication flow in crates/api

The repo supports multiple LLM providers (Anthropic, Azure, Bedrock, Cohere, Copilot) via src-rust/crates/api/src/providers/, but there are no visible integration tests validating auth flows across providers. With auth.rs and provider_error.rs in place, adding tests would catch provider-specific auth failures early and document expected behavior.

• [ ] Create src-rust/crates/api/tests/integration_tests.rs
• [ ] Add test cases for each provider's auth flow: anthropic.rs, azure.rs, bedrock.rs, cohere.rs, copilot.rs
• [ ] Test error handling paths via provider_error.rs
• [ ] Document test setup in docs/auth.md (which exists but likely needs provider-specific examples)
• [ ] Ensure tests mock external API calls to avoid credential exposure

Implement missing CI workflow for Rust crate builds and clippy linting

The repo has .github/workflows/pages.yml and release.yml, but no workflow for running cargo test, cargo build, and clippy on pull requests. With 12 workspace crates (core, api, tools, query, tui, commands, mcp, bridge, cli, buddy, plugins, acp) defined in Cargo.toml, a build matrix is needed to catch regressions early.

• [ ] Create .github/workflows/rust-ci.yml
• [ ] Configure matrix build for Rust stable/nightly on Linux/macOS
• [ ] Add steps: cargo check, cargo clippy --all-targets, cargo test --workspace
• [ ] Include cargo fmt --check to enforce code style
• [ ] Test devcontainer build via .devcontainer/Dockerfile

Add comprehensive example configurations and validation in docs/configuration.md with schema file

The repo has extensive configuration capability (agents, hooks, providers, commands per docs/ structure) but docs/configuration.md exists without visible schema examples. Contributors and users need concrete examples of TOML/JSON config structures, especially for the 12 crates with different concerns (TUI, MCP, plugins, bridges).

• [ ] Create docs/configuration-schema.md documenting TOML structure for core config sections: [providers], [agents], [commands], [hooks], [plugins]
• [ ] Add 3-5 complete example config files in docs/examples/ (e.g., minimal.toml, advanced.toml, mcp-enabled.toml)
• [ ] Reference the provider_types.rs and model_registry.rs to document available provider/model configurations
• [ ] Add validation hints to prevent misconfiguration (required fields, type requirements)
• [ ] Link examples from docs/installation.md first-run setup section

• Add integration tests for tool execution in crates/tools/src/executor.rs — test subprocess spawning, signal handling, and output capture with mock binaries. Currently zero test coverage visible.: medium: Safety-critical code (executes arbitrary user commands) with no visible test harness
• Document the SQLite schema and migration process in docs/database.md — currently undocumented. Trace schema initialization in crates/tools/src/ and explain the message history table structure.: easy: Critical for users debugging local state or contributors modifying message storage
• Add OpenTelemetry tracing instrumentation to the agent loop in crates/core/src/agent.rs and provider calls in crates/api/src/ — currently uses basic tracing subscriber without structured observability.: medium: Production deployments need performance visibility; this enables request tracing and latency analysis across providers

• High · Incomplete Dependencies Configuration — src-rust/Cargo.toml. The Cargo.toml workspace dependencies definition is truncated at 'tokio-util = { versio'. This incomplete dependency specification could lead to unintended version resolution, potentially pulling vulnerable or incompatible versions of tokio-util and other dependencies. Fix: Complete the truncated dependency specification and ensure all workspace dependencies are fully defined with explicit versions. Run 'cargo check' and 'cargo audit' to verify dependency integrity.
• High · Use of Native TLS Without Pinning — src-rust/Cargo.toml - reqwest dependency. The reqwest dependency is configured with 'native-tls' feature, which relies on the system's certificate store. Without certificate pinning, the application is vulnerable to MITM attacks if the system's CA store is compromised or misconfigured. Fix: Implement certificate pinning for critical API endpoints, particularly for authentication and sensitive data transmission. Consider using rustls instead of native-tls for better control over TLS configuration.
• High · Potential SQL Injection via SQLite — src-rust/Cargo.toml - rusqlite dependency, src-rust/crates/tools, src-rust/crates/commands. The codebase includes rusqlite dependency without visible evidence of parameterized query usage in the file structure. The presence of user-facing tools and commands increases risk of SQL injection if queries are constructed with user input. Fix: Audit all database queries to ensure parameterized statements are used exclusively. Never concatenate user input into SQL queries. Use rusqlite's params!() macro for all queries.
• High · Multi-Provider Authentication Without Visible Validation — src-rust/crates/api/src/auth.rs, src-rust/crates/api/src/providers/. The codebase supports multiple AI providers (Anthropic, Azure, OpenAI, Google, Bedrock, etc.) with authentication via API keys. The auth.rs and provider files suggest credential handling, but no visible validation of secure storage mechanisms. Fix: Implement secure credential storage using OS credential managers (keyring, Credential Manager). Never log or display API keys. Use environment variables with restricted permissions. Implement API key rotation policies.
• High · Unsafe Process Execution Capability — src-rust/Cargo.toml - enigo dependency, src-rust/crates/tools. Dependencies include 'enigo' (keyboard/mouse control) and the file structure suggests tool execution capabilities. Without proper sandboxing, this enables potential code execution vulnerabilities if user input flows to process execution. Fix: Implement strict input validation and sanitization for any user-controlled parameters passed to process execution. Use seccomp or other sandboxing mechanisms. Whitelist allowed commands and arguments.
• Medium · Terminal Output Injection Risk — src-rust/crates/tui/. The TUI implementation uses ratatui and crossterm for terminal UI. If user/AI-generated content is rendered without proper escaping, terminal escape sequences could be injected to manipulate the UI or potentially execute terminal commands. Fix: Sanitize all user-controlled and AI-generated content before rendering. Strip or escape terminal control sequences. Use ratatui's safe text rendering APIs rather than raw terminal writes.
• Medium · Plugin System Without Visible Signature Verification — src-rust/crates/plugins/. The codebase includes a plugins crate, but no visible mechanism for verifying plugin signatures or sandboxing plugin execution. Arbitrary plugin loading could allow code execution attacks. Fix: Implement cryptographic signature verification for all plugins. Load plugins in restricted environments with minimal permissions. Maintain a whitelist of approved plugins. Consider using WebAssembly for plugin sandboxing.
• Medium · Model Registry Without Visible Validation — src-rust/crates/api/src/model_registry.rs. The model_registry.rs suggests dynamic model selection and configuration. Without proper validation, an attacker could potentially specify malicious models or endpoints. Fix: Validate all model identifiers and endpoints against a hardcoded whitelist. Implement strict URL validation for provider endpoints. Use allow-lists rather than block-lists for supported models.
• Medium · undefined — undefined. undefined Fix: undefined
