    Platform              Core               Agent

• Platform — Messaging platform adapter. Handles receiving/sending messages over WebSocket, Stream, etc.
• Agent — AI assistant adapter. Invokes the local AI tool and collects its response.
• Engine — Core router. Manages sessions, routes messages between platforms and agents, handles slash commands.

All components are decoupled via Go interfaces — fully pluggable and extensible.

Platform Setup Guides

Each platform requires creating a bot/app on the platform's developer console. We provide detailed step-by-step guides:

Platform	Guide	Connection	Public IP?
Feishu (Lark)	docs/feishu.md	WebSocket	No
DingTalk	docs/dingtalk.md	Stream	No
Telegram	docs/telegram.md	Long Polling	No
Slack	docs/slack.md	Socket Mode	No

Quick config examples for each platform:

# Feishu
[[projects.platforms]]
type = "feishu"
[projects.platforms.options]
app_id = "cli_xxxx"
app_secret = "xxxx"

# DingTalk
[[projects.platforms]]
type = "dingtalk"
[projects.platforms.options]
client_id = "dingxxxx"
client_secret = "xxxx"

# Telegram
[[projects.platforms]]
type = "telegram"
[projects.platforms.options]
token = "123456:ABC-xxx"

# Slack
[[projects.platforms]]
type = "slack"
[projects.platforms.options]
bot_token = "xoxb-xxx"
app_token = "xapp-xxx"

# Discord
[[projects.platforms]]
type = "discord"
[projects.platforms.options]
token = "your-discord-bot-token"

# LINE (requires public URL)
[[projects.platforms]]
type = "line"
[projects.platforms.options]
channel_secret = "xxx"
channel_token = "xxx"
port = "8080"

# WeChat Work (requires public URL)
[[projects.platforms]]
type = "wecom"
[projects.platforms.options]
corp_id = "wwxxx"
corp_secret = "xxx"
agent_id = "1000002"
callback_token = "xxx"
callback_aes_key = "xxx"
port = "8081"
enable_markdown = false  # true only if all users use WeChat Work app (not personal WeChat)

# QQ (via NapCat/OneBot v11, no public IP needed)
[[projects.platforms]]
type = "qq"
[projects.platforms.options]
ws_url = "ws://127.0.0.1:3001"
allow_from = "*"  # QQ user IDs, e.g. "12345,67890" or "*" for all

Permission Modes

Both agents support permission modes switchable at runtime via /mode.

Claude Code modes (maps to --permission-mode):

Mode	Config Value	Behavior
Default	default	Every tool call requires user approval.
Accept Edits	acceptEdits (alias: edit)	File edit tools auto-approved; other tools still ask.
Plan Mode	plan	Claude only plans — no execution until you approve.
YOLO	bypassPermissions (alias: yolo)	All tool calls auto-approved. For trusted/sandboxed environments.

Codex modes (maps to --ask-for-approval):

Mode	Config Value	Behavior
Suggest	suggest	Only trusted commands (ls, cat...) run without approval.
Auto Edit	auto-edit	Model decides when to ask; sandbox-protected.
Full Auto	full-auto	Auto-approve with workspace sandbox. Recommended.
YOLO	yolo	Bypass all approvals and sandbox.

# Claude Code
[projects.agent.options]
mode = "default"
# allowed_tools = ["Read", "Grep", "Glob"]

# Codex
[projects.agent.options]
mode = "full-auto"
# model = "o3"

Switch mode at runtime from the chat:

/mode          # show current mode and all available modes
/mode yolo     # switch to YOLO mode
/mode default  # switch back to default

API Provider Management Beta

Switch between different API providers (e.g. Anthropic direct, relay services, AWS Bedrock) at runtime — no restart needed. Provider credentials are injected as environment variables into the agent subprocess, so your local config stays untouched.

Configure Providers

In config.toml:

[projects.agent.options]
work_dir = "/path/to/project"
provider = "anthropic"   # active provider name

[[projects.agent.providers]]
name = "anthropic"
api_key = "sk-ant-xxx"

[[projects.agent.providers]]
name = "relay"
api_key = "sk-xxx"
base_url = "https://api.relay-service.com"
model = "claude-sonnet-4-20250514"

# For special setups (Bedrock, Vertex, etc.), use the env map:
[[projects.agent.providers]]
name = "bedrock"
env = { CLAUDE_CODE_USE_BEDROCK = "1", AWS_PROFILE = "bedrock" }

Via CLI:

cc-connect provider add --project my-backend --name relay --api-key sk-xxx --base-url https://api.relay.com
cc-connect provider add --project my-backend --name bedrock --env CLAUDE_CODE_USE_BEDROCK=1,AWS_PROFILE=bedrock
cc-connect provider list --project my-backend
cc-connect provider remove --project my-backend --name relay

Import from cc-switch:

If you already use cc-switch to manage providers, import them with one command (requires sqlite3):

cc-connect provider import --project my-backend
cc-connect provider import --project my-backend --type claude     # only Claude providers
cc-connect provider import --db-path ~/.cc-switch/cc-switch.db    # explicit DB path

Manage Providers in Chat

/provider                   Show current active provider
/provider list              List all configured providers
/provider add <name> <key> [url] [model]   Add a provider
/provider add {"name":"relay","api_key":"sk-xxx","base_url":"https://..."}
/provider remove <name>     Remove a provider
/provider switch <name>     Switch to a provider
/provider <name>            Shortcut for switch

Adding, removing, and switching providers all persist to config.toml automatically. Switching restarts the agent session with the new credentials.

Env var mapping by agent type:

Agent	api_key →	base_url →
Claude Code	ANTHROPIC_API_KEY	ANTHROPIC_BASE_URL
Codex	OPENAI_API_KEY	OPENAI_BASE_URL
Gemini CLI	GEMINI_API_KEY	— (use env map)

The env map in provider config lets you set arbitrary environment variables for any setup (Bedrock, Vertex, Azure, custom proxies, etc.).

Voice Messages (Speech-to-Text) Beta

Send voice messages directly — cc-connect transcribes them to text using a configurable STT provider, then forwards the text to the agent.

Supported platforms: Feishu, WeChat Work, Telegram, LINE, Discord, Slack

Prerequisites:

• An API key for OpenAI or Groq (for Whisper STT)
• ffmpeg installed (for audio format conversion — most platforms send AMR/OGG which Whisper doesn't accept directly)

Configure

[speech]
enabled = true
provider = "openai"    # "openai" or "groq"
language = ""          # e.g. "zh", "en"; empty = auto-detect

[speech.openai]
api_key = "sk-xxx"     # your OpenAI API key
# base_url = ""        # custom endpoint (optional, for OpenAI-compatible APIs)
# model = "whisper-1"  # default model

# -- OR use Groq (faster and cheaper) --
# [speech.groq]
# api_key = "gsk_xxx"
# model = "whisper-large-v3-turbo"

How It Works

1. User sends a voice message on any supported platform
2. cc-connect downloads the audio from the platform
3. If the format needs conversion (AMR, OGG → MP3), ffmpeg handles it
4. Audio is sent to the Whisper API for transcription
5. Transcribed text is shown to the user and forwarded to the agent

Install ffmpeg

# Ubuntu / Debian
sudo apt install ffmpeg

# macOS
brew install ffmpeg

# Alpine
apk add ffmpeg

Session Management

Each user gets an independent session with full conversation context. Manage sessions via slash commands:

/new [name]       Start a new session
/list             List all agent sessions for this project
/switch <id>      Switch to a different session
/current          Show current session info
/history [n]      Show last n messages (default 10)
/provider [...]   Manage API providers (list/add/remove/switch)
/allow <tool>     Pre-allow a tool (takes effect on next session)
/mode [name]      View or switch permission mode
/quiet            Toggle thinking/tool progress messages
/stop             Stop current execution
/help             Show available commands

During a session, the agent may request tool permissions. Reply allow / deny / allow all (auto-approve all remaining requests this session).

Configuration

Each [[projects]] entry binds one code directory to its own agent and platforms. A single cc-connect process can manage multiple projects simultaneously.

# Project 1
[[projects]]
name = "my-backend"

[projects.agent]
type = "claudecode"

[projects.agent.options]
work_dir = "/path/to/backend"
mode = "default"

[[projects.platforms]]
type = "feishu"

[projects.platforms.options]
app_id = "cli_xxxx"
app_secret = "xxxx"

# Project 2 — Codex agent with Telegram
[[projects]]
name = "my-frontend"

[projects.agent]
type = "codex"

[projects.agent.options]
work_dir = "/path/to/frontend"
mode = "full-auto"

[[projects.platforms]]
type = "telegram"

[projects.platforms.options]
token = "xxxx"

See config.example.toml for a fully commented configuration template.

Extending

Adding a New Platform

Implement the core.Platform interface and register it:

package myplatform

import "github.com/chenhg5/cc-connect/core"

func init() {
    core.RegisterPlatform("myplatform", New)
}

func New(opts map[string]any) (core.Platform, error) {
    return &MyPlatform{}, nil
}

// Implement Name(), Start(), Reply(), Send(), Stop()

Then add a blank import in cmd/cc-connect/main.go:

_ "github.com/chenhg5/cc-connect/platform/myplatform"

Adding a New Agent

Same pattern — implement core.Agent and register via core.RegisterAgent.
