# Hook Bug Workarounds
Community-tested workarounds for current Claude Code bugs that can affect ECC hook-heavy setups.
This page is intentionally narrow: it collects the highest-signal operational fixes from the longer troubleshooting surface without repeating speculative or unsupported configuration advice. These are upstream Claude Code behaviors, not ECC bugs.
## When To Use This Page
Use this page when you are specifically debugging:
- false `Hook Error` labels on otherwise successful hook runs
- earlier-than-expected compaction
- MCP connectors that look authenticated but fail after compaction
- hook edits that do not hot-reload
- repeated `529 Overloaded` responses under heavy hook/tool pressure
For the fuller ECC troubleshooting surface, use [TROUBLESHOOTING.md](./TROUBLESHOOTING.md).
## High-Signal Workarounds
### False `Hook Error` labels
What helps:
- Consume stdin at the start of shell hooks (`input=$(cat)`).
- Keep stdout quiet for simple allow/block hooks unless your hook explicitly requires structured stdout.
- Send human-readable diagnostics to stderr.
- Use the correct exit codes: `0` allow, `2` block, other non-zero values are treated as errors.
```bash
input=$(cat)
echo "[BLOCKED] Reason here" >&2
exit 2
```
### Earlier-than-expected compaction
What helps:
- Remove `CLAUDE_AUTOCOMPACT_PCT_OVERRIDE` if lowering it causes earlier compaction in your build.
- Prefer manual `/compact` at natural task boundaries.
- Use ECC's `strategic-compact` guidance instead of forcing a lower threshold.
### MCP auth looks live but fails after compaction
What helps:
- Toggle the affected connector off and back on after compaction.
- If your Claude Code build supports it, add a lightweight `PostCompact` reminder hook that tells you to re-check connector auth.
- Treat this as a recovery reminder, not a permanent fix.
### Hook edits do not hot-reload
What helps:
- Restart the Claude Code session after changing hooks.
- Advanced users sometimes use shell-local reload helpers, but ECC does not ship one because those approaches are shell- and platform-dependent.
### Repeated `529 Overloaded`
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.
