a0bcd93a88 fix(slack): improve file download error handling and auth diagnostics (#204)
When downloading Slack files via url_private_download, the code was
already setting the Bearer token correctly. However, there was no
error detection for cases where Slack returns an HTML login page
instead of the actual file content.

This commit adds:
- Fallback to url_private when url_private_download is empty
- Status code validation (fail on non-200 responses)
- HTML content detection (fail with clear error message)
- Improved error logging with redacted URL
- Unit tests for the downloadSlackFile function

The HTML detection is particularly important because when auth
fails (e.g., wrong bot token, expired token), Slack returns a
login page with HTTP 200 instead of an error code. Without this
check, the HTML content would be passed to the AI agent as if
it were an image, causing confusing errors.

Fixes #185

Control your local AI agents from any chat app. Anywhere, anytime.

cc-connect bridges AI agents running on your machine to the messaging platforms you already use.
Code review, research, automation, data analysis — anything an AI agent can do,
now accessible from your phone, tablet, or any device with a chat app.

CC-Connect Architecture


✨ Why cc-connect?

🤖 Universal Agent Support

7 AI Agents — Claude Code, Codex, Cursor Agent, Qoder CLI, Gemini CLI, OpenCode, iFlow CLI. Use whichever fits your workflow, or all of them at once.

📱 Platform Flexibility

9 Chat Platforms — Feishu, DingTalk, Slack, Telegram, Discord, WeChat Work, LINE, QQ, QQ Bot (Official). Most need zero public IP.

🔄 Multi-Agent Orchestration

Multi-Bot Relay — Bind multiple bots in a group chat and let them communicate with each other. Ask Claude, get insights from Gemini — all in one conversation.

🎮 Complete Chat Control

Full Control from Chat — Switch models (/model), tune reasoning (/reasoning), change permission modes (/mode), manage sessions, all via slash commands.

🧠 Persistent Memory

Agent Memory — Read and write agent instruction files (/memory) without touching the terminal.

⏰ Intelligent Scheduling

Scheduled Tasks — Set up cron jobs in natural language. "Every day at 6am, summarize GitHub trending" just works.

🎤 Multimodal Support

Voice & Images — Send voice messages or screenshots; cc-connect handles STT/TTS and multimodal forwarding.

📦 Multi-Project Architecture

Multi-Project — One process, multiple projects, each with its own agent + platform combo.

🌍 Multilingual Interface

5 Languages — Native support for English, Chinese (Simplified & Traditional), Japanese, and Spanish. Built-in i18n ensures everyone feels at home.

📎 Agent Attachment Send-Back

When an agent generates a local screenshot, chart, PDF, bundle, or other file, it can send that attachment back to the current chat.

First release supports:

  • Feishu
  • Telegram

If your agent does not natively inject the system prompt, run this once in chat after upgrading:

/bind setup

or:

/cron setup

This refreshes the cc-connect instructions in the project memory file so the agent knows how to send attachments back.

You can control this feature globally in config.toml:

attachment_send = "on"  # default: "on"; set to "off" to block image/file send-back

This switch is independent from the agent's /mode. It only controls cc-connect send --image/--file.

Examples:

cc-connect send --image /absolute/path/to/chart.png
cc-connect send --file /absolute/path/to/report.pdf
cc-connect send --file /absolute/path/to/report.pdf --image /absolute/path/to/chart.png

Notes:

  • Absolute paths are the safest option.
  • --image and --file can both be repeated.
  • attachment_send = "off" disables only attachment send-back; ordinary text replies still work.
  • This command is for generated attachments, not ordinary text replies.
