CleverAgents Core

CleverAgents is the Python-first migration of the Plandex automation platform. It provides a unified agents CLI, embedded runtime, and service orchestration tools that mirror the original Go workflows while embracing modern Python tooling.

Highlights

• Unified CLI entry points: cleveragents and agents
• Fast Typer/Click-based interface with parity for help/version behavior
• Behavior-driven coverage via Behave and Robot Framework
• Nox automation for linting, typing, testing, docs, builds, and benchmarks
• MkDocs-powered documentation with CleverAgents branding

Tests

Behave feature scenarios live under features/ and Robot suites under robot/. Use the Nox sessions above to execute them in parity with the implementation plan.

Observability

LangSmith tracing is optional and off by default. Enable it by exporting CLEVERAGENTS_LANGSMITH_ENABLED=true along with a project name and API key (CLEVERAGENTS_LANGSMITH_PROJECT, CLEVERAGENTS_LANGSMITH_API_KEY). The settings module automatically mirrors these values to LANGCHAIN_TRACING_V2, LANGCHAIN_PROJECT, and LANGCHAIN_API_KEY, so LangChain/LangGraph agents emit traces without extra wiring. Additional knobs such as CLEVERAGENTS_LANGSMITH_ENDPOINT, CLEVERAGENTS_LANGSMITH_USER_ID, and CLEVERAGENTS_LANGSMITH_TAGS are documented in docs/observability.md.

LLM provider configuration

CleverAgents ships with a LangChain/LangGraph powered provider registry that discovers whichever API keys you export and automatically selects the best available provider. The CLI always prefers explicit choices (agents tell --provider anthropic --model claude-sonnet-4-20250514), followed by CLEVERAGENTS_DEFAULT_PROVIDER and CLEVERAGENTS_DEFAULT_MODEL, then any defaults defined inside Settings, and finally the built-in fallback order (openai → anthropic → google → azure → openrouter → groq → together → cohere → gemini).

Required environment variables

Provider	Primary variables
OpenAI	OPENAI_API_KEY
Anthropic	ANTHROPIC_API_KEY
Google	GOOGLE_API_KEY or GOOGLE_GENAI_API_KEY
Azure OpenAI	AZURE_OPENAI_API_KEY plus AZURE_OPENAI_ENDPOINT/AZURE_OPENAI_DEPLOYMENT
OpenRouter	OPENROUTER_API_KEY (+ optional CLEVERAGENTS_OPENROUTER_ORGANIZATION for sanitized headers)
Gemini	GEMINI_API_KEY or GOOGLE_GEMINI_API_KEY
Cohere	COHERE_API_KEY
Groq	GROQ_API_KEY
Together	TOGETHER_API_KEY

Set CLEVERAGENTS_DEFAULT_PROVIDER to pin the global provider (for example export CLEVERAGENTS_DEFAULT_PROVIDER=openai) and CLEVERAGENTS_DEFAULT_MODEL to lock in a model ID. When unset, the registry picks the first configured provider and uses its published default model such as gpt-4o for OpenAI or claude-sonnet-4-20250514 for Anthropic.

Diagnostics and testing shortcuts

• agents diagnostics prints whether the registry can see your credentials.
• agents tell and agents build accept --provider/--model flags for one-off overrides.
• CLEVERAGENTS_TESTING_USE_MOCK_AI=true forces the in-repo mock provider so Behave/Robot suites never hit external APIs.
• The full capability matrix (streaming, tool calls, JSON mode, etc.) plus every supported environment variable is documented in docs/reference/providers.md and docs/reference/env_variables.yaml.
