Telegram plugin: frequent HTTP 401 errors mid-session

Description

The Telegram plugin (v0.0.5) frequently returns HTTP 401 authentication errors while a Claude Code session is actively running. The error message is:

HTTP 401: authentication_error: Invalid authentication credentials

Reproduction steps

1. Start a Claude Code session with the Telegram channel enabled (--channels plugin:telegram@claude-plugins-official)
2. Send messages from Telegram to the bot
3. Some messages succeed, but frequently the bot replies with the 401 error
4. Restarting the Claude Code session temporarily resolves the issue

Expected behavior

Messages sent via Telegram should be processed without authentication errors for the duration of the active session.

Actual behavior

The bot process stays alive (no crash), but the Claude API rejects requests with a 401 error intermittently. This suggests the internal auth token used by the plugin system is being invalidated or expiring mid-session without proper refresh.

Environment

• macOS (Darwin 24.6.0)
• Telegram plugin version: 0.0.5
• Bot process remains running (confirmed via ps)
• Error originates from the Claude API, not the Telegram Bot API
