Implements Issue #28 - modernize CLI commands for better Claude integration.
Key changes:
- Add JSON output format support with --output-format flag (default: json)
- Add session continuity with --continue flag and .claude_session_id file
- Add tool permissions via --allowed-tools flag
- Add build_loop_context() for loop-aware context injection
- Add detect_output_format() and parse_json_response() for JSON parsing
- Maintain backward compatibility with text output fallback
- Add version checking with check_claude_version()
New CLI options:
- --output-format json|text: Control Claude output format
- --allowed-tools "Write,Read,Bash(git *)": Restrict tool permissions
- --no-continue: Disable session continuity
Test coverage:
- 20 new JSON parsing tests (test_json_parsing.bats)
- 23 new CLI modern tests (test_cli_modern.bats)
- All 98 tests passing (100% pass rate)
Update all base directory documentation to accurately reflect current codebase state:
- IMPLEMENTATION_PLAN.md: Correct CI/CD status (operational), update test counts (75 actual),
clarify week completion status (1-2 + partial 5 complete)
- IMPLEMENTATION_STATUS.md: Add verification dates, detailed test breakdowns, updated remaining
work estimates, recent improvements section
- STATUS.md: Update from 35 to 75 tests, add integration test details, include lib/ modules
- PHASE1_COMPLETION.md & PHASE2_COMPLETION.md: Add historical milestone notes
Key corrections:
- CI/CD pipeline IS operational (.github/workflows/test.yml)
- install.sh DOES copy lib/ directory (verified lines 78, 91, 148)
- 75 tests accurately reported (15 rate + 20 exit + 20 loop + 20 edge)
- Week 5 partially complete (edge cases done, features not implemented)
- Weeks 3-4 and 6 not started (accurate status vs. optimistic claims)
All documentation now synchronized with codebase as of 2025-12-31.
Add -u flag to GNU date command in get_iso_timestamp() to match
the macOS implementation and function documentation. Both platforms
now consistently return UTC timestamps in YYYY-MM-DDTHH:MM:SS+00:00
format.
Before: date -Iseconds (returned local time on Linux)
After: date -u -Iseconds (returns UTC on Linux)
Add cross-platform date utility library to handle differences between
GNU date (Linux) and BSD date (macOS). Fixes issues with:
- ISO 8601 timestamp formatting (-Iseconds flag)
- Date arithmetic operations (-d vs -v flags)
Changes:
- Created lib/date_utils.sh with get_iso_timestamp() and get_next_hour_time()
- Updated ralph_loop.sh to use date utilities (2 instances)
- Updated lib/circuit_breaker.sh to use date utilities (4 instances)
- Updated lib/response_analyzer.sh to use date utilities (1 instance)
All date operations now work consistently across both platforms without
modification. The utility automatically detects the OS and uses the
appropriate date command syntax.
Tested on Linux with GNU date - all syntax checks and integration tests pass.
Updated both documentation files to reflect recent enhancements and fixes:
CLAUDE.md Changes:
- Added comprehensive Core Architecture section detailing main scripts and lib/ components
- Documented lib/circuit_breaker.sh and lib/response_analyzer.sh modular architecture
- Added detailed Exit Conditions and Thresholds section with circuit breaker thresholds
- Documented advanced two-stage error detection process to eliminate false positives
- Documented multi-line error matching for accurate stuck loop detection
- Added Recent Improvements section highlighting v0.9.0 circuit breaker enhancements
- Updated Global Installation section to include lib/ directory and ralph-import command
- Test coverage details: 13 error detection + 9 stuck loop tests
README.md Changes:
- Updated "What's Working Now" section with circuit breaker enhancements
- Added "Recent Improvements" section highlighting v0.9.0 updates
- Updated test count from 75 to 97 tests (75 core + 13 error detection + 9 stuck loop)
- Enhanced circuit breaker description with two-stage filtering details
- Added circuit breaker thresholds to Exit Thresholds section
- Updated test commands to include error detection and stuck loop test scripts
- Updated current test status with specialized test file counts
Key improvements documented:
- Multi-line error matching fix for detect_stuck_loop function
- JSON field false positive elimination (e.g., "is_error": false)
- Two-stage error filtering for accurate error detection
- Installation fix for lib/ directory components
- 22 new tests added for circuit breaker functionality
These updates ensure documentation accurately reflects the current state of the
codebase following PR #6 (circuit-breaker false positives fix) and PR #4
(installation lib/ directory fix).
Addresses CodeRabbit outside diff range comment on lines 268-283:
CRITICAL BUG:
The detect_stuck_loop function had a multi-line string handling bug where
only the first error line was checked against historical outputs when
multiple distinct errors were present.
Problem:
grep -q "$current_errors" file.log
# When $current_errors has multiple lines, grep only matches first line
Impact:
Stuck loops with multiple recurring errors would not be detected correctly,
potentially allowing Ralph to continue running despite being genuinely stuck.
Fix:
Changed from simple grep to nested loop checking:
- For each historical output file
- For each error line in current output
- ALL error lines must appear in that file
- Only returns "stuck" if ALL files contain ALL current errors
Used grep -qF for literal fixed-string matching (not regex) to avoid
edge cases with special characters in error messages.
Test Coverage:
Added 2 new test scenarios (7 → 9 total tests):
Test 8: Multiple distinct errors where ALL repeat across history
Current: Error: Build failed + Fatal: DB lost + Exception: NPE
History: All 3 files contain all 3 errors
Expected: Stuck detected ✅
Test 9: Multiple errors where only some repeat
Current: Error: Build failed + Fatal: DB lost
History: Only first error appears consistently
Expected: Not stuck ✅
All existing tests continue to pass, validating backward compatibility.
Test results:
✓ Error detection tests: 13/13 passing
✓ Stuck loop tests: 9/9 passing (was 7/7)
✓ Total: 22/22 tests passing
This ensures detect_stuck_loop correctly handles the real-world scenario
where Ralph gets stuck on multiple simultaneous recurring errors.
Addresses CodeRabbit review comment:
- Outside diff range (lines 268-283): Multi-line error matching bug
Addresses additional CodeRabbit findings in lib/response_analyzer.sh:
CRITICAL (line 267):
- Fixed detect_stuck_loop() to use two-stage filtering
- Was using naive grep -i "error\|failed" pattern
- Now filters JSON fields before extracting errors
- Pattern aligned with analyze_response() for consistency
DEAD CODE (line 18):
- Removed unused STUCK_INDICATORS array
- Array was defined but never referenced in code
- Reduces maintenance burden per coding guidelines
TEST COVERAGE:
- Added comprehensive test suite for detect_stuck_loop()
- New file: tests/test_stuck_loop_detection.sh
- 7 test scenarios validating:
* JSON fields don't trigger false stuck detection
* Actual repeated errors are correctly detected
* Type annotations are properly excluded
* Function returns appropriate exit codes
Test results:
✓ Error detection tests: 13/13 passing
✓ Stuck loop tests: 7/7 passing
✓ Total: 20/20 tests passing
This ensures both error detection functions (analyze_response and
detect_stuck_loop) use identical filtering logic, preventing circuit
breaker false positives across all code paths.
Addresses CodeRabbit review comments:
- Outside diff range comment: line 267 (Critical)
- Outside diff range comment: line 18 (Dead code)
- Outside diff range comment: lines 254-286 (Test coverage)
Aligns error detection patterns across all implementations and improves
test coverage based on CodeRabbit's critical and major findings.
Changes:
1. CRITICAL: Align lib/response_analyzer.sh pattern with ralph_loop.sh
- Changed Stage 1 filter from '"[^"]*\(error\|failed\)"[^"]*":' to '"[^"]*error[^"]*":'
- Removed bare 'cannot' and 'unable to' from Stage 2 (prevent false positives in prose)
- Both files now use identical patterns for consistency
2. MAJOR: Improved test coverage
- Renamed test 10 from "Cannot/unable in error context" to "Error prefix with descriptive message"
- Added test 10a to validate bare "cannot/unable" DON'T trigger false positives
- Now testing 13 scenarios (was 12)
3. MINOR: Added comprehensive test strategy documentation
- Header comments explain two-stage filtering approach
- Documents pattern consistency requirement
- Lists all 13 test scenarios and their purpose
Test results:
✓ All 13 tests passing
✓ Pattern consistency validated across ralph_loop.sh and lib/response_analyzer.sh
✓ False positive scenarios properly excluded
Addresses CodeRabbit review comments:
- r2655862688 (Critical pattern inconsistency)
- r2655862689 (Major test coverage gap)
- r2655862690 (Minor misleading test name)
Fixes circuit breaker opening prematurely due to naive error pattern matching
that treated JSON field names like "is_error": false as actual errors.
Changes:
- ralph_loop.sh: Implement two-stage error detection with JSON filtering
- lib/response_analyzer.sh: Apply same filtering to error counting
- tests/test_error_detection.sh: Add comprehensive test suite (12 scenarios)
Error detection now:
- Filters out JSON field patterns before searching for errors
- Uses context-specific patterns (^Error:, ]: error, Exception, Fatal)
- Avoids type annotations (error: Error) and code identifiers
- Includes debug logging when VERBOSE_PROGRESS=true
Test coverage validates:
✓ JSON fields don't trigger false positives
✓ Real error messages are correctly detected
✓ Mixed content handled properly
✓ Code diffs and documentation excluded
This prevents the consecutive_same_error counter from incrementing on
false positives, eliminating unnecessary circuit breaker trips.
The install.sh was missing the lib/ directory copy, causing ralph_loop.sh
to fail when sourcing response_analyzer.sh and circuit_breaker.sh.
Changes:
- Add mkdir -p "$RALPH_HOME/lib" to create_install_dirs()
- Add cp -r "$SCRIPT_DIR/lib/"* "$RALPH_HOME/lib/" to install_scripts()
- Add chmod +x for lib/*.sh scripts

- Added attribution to Paul Gauthier as creator of the Ralph technique
- Documented new 5-hour API limit detection and handling feature
- Added documentation for --verbose and --timeout options
- Included complete Ralph Loop Options reference section
- Updated Features section with new capabilities
- Enhanced troubleshooting section with API limit and timeout guidance
- Corrected command examples to match actual implementation
- Added detection for API 5-hour limit error messages in execute_claude_code()
- Returns special exit code (2) when API limit is detected
- Added interactive prompt for user to choose: wait 60 minutes or exit
- Implements proper countdown timer when waiting for API reset
- Prevents infinite 30-second retry loops on API limit errors
- Improves status tracking with new api_limit and api_limit_exit states
The original `|| echo 0` fallback was executing even when grep -c succeeded
but returned 0 matches (exit code 1), resulting in "0\n0" being assigned
to variables. This multi-line string caused syntax errors in [[ ]] tests.
Fixed by removing the fallback and explicitly handling empty variables
instead, which properly addresses the root cause of the line 280 error.
Ensures total_items and completed_items are explicitly cast to integers
using $((...)) arithmetic expansion to prevent floating point values
from causing syntax errors in double bracket tests at line 280.
- Eliminate double function call in should_exit_gracefully check
- Use consistent string return pattern instead of mixed return codes
- Resolves script error on line 280 with exit code handling
Features added:
- Added --timeout/-t option to set execution timeout in minutes
- Default timeout increased from 10 to 15 minutes
- Validation: timeout must be 1-120 minutes
- Shows timeout in execution start message
Usage examples:
- ralph --monitor # 15-minute default timeout
- ralph --monitor --timeout 30 # 30-minute timeout for complex tasks
- ralph --verbose --timeout 5 # 5-minute timeout with progress logs
Benefits:
- Prevents hanging on very complex tasks requiring >15 minutes
- Allows shorter timeouts for simpler tasks to fail faster
- User can adjust based on their specific project complexity
- Clear feedback about configured timeout in logs
Key improvements:
- Added --verbose flag to control 10-second progress updates in logs
- Real-time progress now shows in monitor display only (not logs)
- Created progress.json file for monitor communication
- Monitor shows live Claude Code progress with spinner and elapsed time
- Clean logs by default, detailed progress available with --verbose
Usage:
- ralph --monitor # Clean logs, progress in monitor only
- ralph --monitor --verbose # Progress in both monitor and logs
- ralph --verbose # Just verbose logs without monitor
Monitor now displays:
┌─ Claude Code Progress ──────────────────────────────┐
│ Status: ⠋ Working (120s elapsed)
│ Output: Analyzing authentication system...
└─────────────────────────────────────────────────────┘
This keeps logs clean while providing rich real-time feedback in the monitor.
Features added:
- Animated progress spinner (⠋⠙⠹⠸) during Claude Code execution
- Real-time display of last output line from Claude Code
- Timer showing elapsed execution time in 10-second intervals
- 10-minute timeout for Claude Code execution to prevent hanging
- Visual indicators: ⏳ starting, ✅ success, ❌ failure
Counter fixes:
- Fixed call counter jumping issue by only incrementing on successful execution
- Counter now accurately reflects actual successful Claude Code calls
- Prevents double-counting on retries or failures
Monitoring improvements:
- Shows 'Claude Code working... (30s elapsed)' with spinner
- Displays last line of output: 'Claude Code: Reading file... (40s)'
- Clear success/failure indicators in logs
- Better visibility into long-running operations
- Changed from 'npx @anthropic-ai/claude-code' to 'claude'
- This assumes Claude Code is installed globally with npm install -g
- Updated ralph_loop.sh, ralph_import.sh, and README.md
- Much cleaner and faster execution without npx overhead
- Removed npx @anthropic-ai/claude-code --version check during install
- This was causing the install script to hang due to network/auth delays
- Claude Code will be downloaded automatically when first used by Ralph
- Installation should now complete quickly without hanging
- Updated from @anthropic/claude-code to @anthropic-ai/claude-code
- This was causing npm 404 errors when trying to execute Claude Code
- Fixed in ralph_loop.sh, ralph_import.sh, install.sh, and README.md
- Ralph should now be able to successfully execute Claude Code commands
The issue was in line 378: if [[ $? -eq 0 ]]
- $? was checking the return code of 'local exit_reason=$(...)'
- This command always succeeds, so $? was always 0
- This caused Ralph to always exit immediately after loop #1
Fixed by:
- Calling should_exit_gracefully directly in the if condition
- Only calling it again to get exit reason if it returns 0 (exit needed)
- This properly checks the function's actual return code
- Add logging to show total_items and completed_items counts
- Add final debug statement to confirm function completion
- This will help identify if the fix_plan completion check is the culprit
- The debug log_status calls in should_exit_gracefully() were being
captured as stdout when called with
- This caused the debug messages to be treated as the exit reason
- Fixed by redirecting debug logging to stderr with >&2
- Ralph should now continue past the exit condition check properly
- Add debug statements to identify which exit condition is triggering
- Log each step of @fix_plan.md parsing and task completion checking
- Add logging for jq operations and file reading
- This should help identify why Ralph immediately exits after loop #1
