Reduce noisy full-traceback DEBUG logs when an MCP server is skipped because it requires authentication; the actionable warning and a concise debug line remain.


When an MCP server is skipped during discovery because it needs authentication — either a token-refresh (reauth) failure or an RFC 9728 401 OAuth challenge — deepagents-code logged the entire anyio ExceptionGroup / httpx traceback at DEBUG via exc_info, on top of the actionable WARNING. For these already-classified, expected outcomes the traceback adds no diagnostic value and just floods debug output.

These two recognized branches now emit a concise single-line DEBUG breadcrumb (the exception class name only). The full traceback is still logged for genuinely unknown discovery errors (the else branch) and for classifier failures, so real anomalies stay debuggable. The user-facing WARNING is unchanged apart from dropping the now-inaccurate "the original error is in debug logs" note from the reauth message.

Made by Open SWE

Recognized MCP discovery auth failures (OAuth token-refresh failure and
RFC 9728 401 OAuth challenge) logged the full anyio/httpx exception
traceback via exc_info at DEBUG, even though the actionable WARNING
already conveys everything useful and the exception is already
classified. Emit a concise single-line DEBUG breadcrumb (exception type
only) for those two branches, keeping full tracebacks for genuinely
unknown discovery errors.

[0.1.43](deepagents-code==0.1.42...deepagents-code==0.1.43)
(2026-07-17)

### Features

- Added classifier-backed Auto approval mode behind
`DEEPAGENTS_CODE_EXPERIMENTAL=1`
([#4804](#4804)).
- Added a shutdown toast for deferred exits
([#4830](#4830)).
- Task descriptions that were truncated can now be expanded by clicking
or pressing `Ctrl+O`
([#4811](#4811)).
- Debug Console clears with `Ctrl+L` now persist after reopening
([#4812](#4812)).
- Added debug logging for skill-name override collisions
([#4772](#4772)).

### Bug Fixes

- Keep chat input responsive during `/restart`
([#4808](#4808)).
- Fixed paste placeholders disappearing when backspacing a newline below
them ([#4757](#4757)).
- Made markdown `AppMessage` output selectable
([#4814](#4814)).
- Fixed live tool-group counts to include only running tools
([#4809](#4809)).
- Kept `task` timers monotonic across nested subagent human-in-the-loop
flows ([#4771](#4771)).
- Preserved goal criteria proposals when marker clearing fails
([#4785](#4785)).
- Reduced repeated probing of an unreachable Ollama daemon to once per
reload
([#4806](#4806)).
- Quieted MCP auth-skip debug logging for known patterns
([#4805](#4805)).
- Improved `/version` diagnostics for editable installs and core
dependency reporting, including surfacing `langchain-quickjs`
([#4816](#4816),
[#4813](#4813)).
- Removed the `uv install` tip from the `/version` update hint
([#4822](#4822)).

Reduce noisy full-traceback DEBUG logs when an MCP server is skipped
because it requires authentication; the actionable warning and a concise
debug line remain.

---

When an MCP server is skipped during discovery because it needs
authentication — either a token-refresh (`reauth`) failure or an RFC
9728 `401` OAuth challenge — `deepagents-code` logged the entire anyio
`ExceptionGroup` / httpx traceback at DEBUG via `exc_info`, on top of
the actionable WARNING. For these already-classified, expected outcomes
the traceback adds no diagnostic value and just floods debug output.

These two recognized branches now emit a concise single-line DEBUG
breadcrumb (the exception class name only). The full traceback is still
logged for genuinely unknown discovery errors (the `else` branch) and
for classifier failures, so real anomalies stay debuggable. The
user-facing WARNING is unchanged apart from dropping the now-inaccurate
"the original error is in debug logs" note from the reauth message.
