Recommended action: Guard profile echoes with an interactive-shell check; put permissionDecision/additionalContext inside hookSpecificOutput; check debug log.
Option: Guard profile echoes with an interactive-shell check; put permissionDecision/additionalContext inside hookSpecificOutput; check debug log. [evidence: official_recommended_action]
Applies when: Command hook returning JSON decision (block/deny/additionalContext)
Steps:
1. Wrap profile echo statements in `if [[ $- == *i* ]]; then ... fi`
2. Or use exec form (`args`) so no shell profile is sourced
3. Move decision fields into hookSpecificOutput
4. Run claude --debug and search for 'Hook JSON output had unrecognized keys'
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
