Troubleshooting

Community-reported workarounds for current Claude Code bugs that can affect ECC users.

These are upstream Claude Code behaviors, not ECC bugs. The entries below summarize the production-tested workarounds collected in issue #644 on Claude Code v2.1.79 (macOS, heavy hook usage, MCP connectors enabled). Treat them as pragmatic stopgaps until upstream fixes land.

Community Workarounds For Open Claude Code Bugs

False "Hook Error" labels on otherwise successful hooks

Symptoms: Hook runs successfully, but Claude Code still shows Hook Error in the transcript.

What helps:

  • Consume stdin at the start of the hook (input=$(cat) in shell hooks) so the parent process does not see an unconsumed pipe.
  • For simple allow/block hooks, send human-readable diagnostics to stderr and keep stdout quiet unless your hook implementation explicitly requires structured stdout.
  • Redirect noisy child-process stderr when it is not actionable.
  • Use the correct exit codes: 0 allows, 2 blocks, other non-zero exits are treated as errors.

Example:

bash
# Good: block with stderr message and exit 2
input=$(cat)
echo "[BLOCKED] Reason here" >&2
exit 2

Earlier-than-expected compaction with CLAUDE_AUTOCOMPACT_PCT_OVERRIDE

Symptoms: Lowering CLAUDE_AUTOCOMPACT_PCT_OVERRIDE causes compaction to happen sooner, not later.

What helps:

  • On some current Claude Code builds, lower values may reduce the compaction threshold instead of extending it.
  • If you want more working room, remove CLAUDE_AUTOCOMPACT_PCT_OVERRIDE and prefer manual /compact at logical task boundaries.
  • Use ECC's strategic-compact guidance instead of forcing a lower auto-compact threshold.

MCP connectors look connected but fail after compaction

Symptoms: Gmail or Google Drive MCP tools fail after compaction even though the connector still looks authenticated in the UI.

What helps:

  • Toggle the affected connector off and back on after compaction.
  • If your Claude Code build supports it, add a PostCompact reminder hook that warns you to re-check connector auth after compaction.
  • Treat this as an auth-state recovery step, not a permanent fix.

Hook edits do not hot-reload

Symptoms: Changes to settings.json hooks do not take effect until the session is restarted.

What helps:

  • Restart the Claude Code session after changing hooks.
  • Advanced users sometimes script a local /reload command around kill -HUP $PPID, but ECC does not ship that because it is shell-dependent and not universally reliable.

Repeated 529 Overloaded responses

Symptoms: Claude Code starts failing under high hook/tool/context pressure.

What helps:

  • Reduce tool-definition pressure with ENABLE_TOOL_SEARCH=auto:5 if your setup supports it.
  • Lower MAX_THINKING_TOKENS for routine work.
  • Route subagent work to a cheaper model such as CLAUDE_CODE_SUBAGENT_MODEL=haiku if your setup exposes that knob.
  • Disable unused MCP servers per project.
  • Compact manually at natural breakpoints instead of waiting for auto-compaction.
