Crate defect_cli 

defect-cli assembly library — reusable by the defect binary and downstream developers.

This crate aims to make “assembling an ACP server” a few lines of code: it translates the typed configuration from defect-config into the runtime structures needed by defect-agent, defect-llm, defect-tools, defect-mcp, and other modules.

Extension points for downstream development

• args::CliArgs / args::CliArgs::to_overrides: standard CLI arguments
• providers::build_registry: assembles ProviderRegistry + TurnConfig
• http_stack::build_http_stack_config: translates typed HTTP configuration into defect_http::HttpStackConfig
• tools::build_process_tools / mcp_servers::build_default_mcp_servers
• hooks::build_engine_arc: assembles the hook engine
• policy::build_policy / paths::default_sessions_root
• tracing initialization has moved to defect-obs (defect_obs::init_tracing)

The main binary src/bin/cli.rs only performs assembly and holds no helper implementations — downstream consumers can replace any step without forking the entire helper set.

Modules

args

CLI argument parsing.

assembly

CLI default AgentCore assembler.

hooks

Translates defect-config hook configuration into the agent’s DefaultHookEngine.

http_stack

Translates the typed HTTP configuration from defect-config into a defect_http::HttpStackConfig.

init

defect init — scan the environment for provider API keys, fetch each detected provider’s real model list over its API, and write a global ~/.config/defect/config.toml.

mcp_servers

Translates the typed configuration from the [mcp] section into a list of ACP McpServer values.

observability

Translates a typed Langfuse config from defect-config into an observer for defect-obs.

oneshot

Single-turn unattended mode —— defect --message <prompt>.

paths

Path resolution helpers — session storage root, etc.

policy

Maps a SandboxMode to a concrete SandboxPolicy instance.

providers

Assembles a ProviderRegistry and individual provider instances.

repl

In-process minimal REPL — defect --repl.

session_open

Opens a session running directly on the local machine — a neutral helper shared by the interactive REPL (repl) and the single-shot (oneshot) paths.

tools

Assembles the process_tools registry.
