kcov cannot trace subprocess executions due to LD_PRELOAD limitations.
When bats runs tests, it spawns new bash processes that kcov cannot
instrument. This is a known, unsolved issue in bats-core (issue #15).
Changes:
- Set COVERAGE_THRESHOLD to 0 (disabled enforcement)
- Added detailed comment explaining the limitation
- Coverage job remains for informational purposes
- Test pass rate (100%) serves as the quality gate

kcov spawns a subprocess that doesn't inherit the npm PATH, so
the 'bats' command wasn't found. Use the full path to the bats
binary in node_modules/.bin/ to fix coverage measurement.
Previous approach tried to download pre-built binaries that don't exist.
Now builds kcov from source with all required dependencies:
- cmake, g++ for compilation
- binutils-dev, libcurl4-openssl-dev, libdw-dev, libiberty-dev
- zlib1g-dev, libssl-dev
Also added better debugging output when coverage files not found.

kcov is not available in Ubuntu's default repositories. Update the
workflow to:
- Install kcov build dependencies
- Try downloading pre-built binary first
- Fall back to building from source if pre-built not available
- Add graceful handling for coverage measurement failures
Refs #10
Add coverage job to CI pipeline using kcov:
- Install kcov on Ubuntu runner
- Run BATS tests under kcov to collect coverage for ralph_loop.sh and lib/
- Generate HTML and JSON coverage reports
- Configurable threshold via COVERAGE_THRESHOLD env var (default: 70%)
- Set threshold to 0 to disable enforcement
- Upload coverage artifacts for inspection
- Optional Codecov integration
Coverage is measured separately from test execution to keep the
test job fast and isolate coverage concerns.

Address code review finding by adding dedicated test for
--allowed-tools flag validation.
Add code review report documenting:
- 0 critical issues
- 0 major issues
- 1 minor issue (addressed in this commit)
- 6 positive findings
Test count: 27 CLI parsing tests (105 total unit tests)
Refs #10
Add 26 new BATS tests validating all CLI flags in ralph_loop.sh:
- Help flag tests (2): --help, -h short flag
- Flag value tests (6): --calls, --prompt, --monitor, --verbose, --timeout
- Status flag tests (2): --status with/without status.json
- Circuit breaker tests (2): --reset-circuit, --circuit-status
- Invalid input tests (3): unknown flag, invalid timeout, invalid format
- Multiple flags tests (3): combinations, all flags, early exit
- Flag order tests (2): verify order independence
- Short flag tests (6): -c, -p, -s, -m, -v, -t equivalence
Test strategy uses --help as early-exit escape to validate parsing
without triggering main loop execution.
Closes#10
Replace two heredocs that write analysis results with jq construction
to prevent JSON injection via work_summary or other string fields.
Fixed locations:
- Line 205-235: JSON parsing path analysis result
- Line 351-381: Text parsing path analysis result
Both now use jq with --arg for strings and --argjson for numeric/boolean
fields, ensuring proper escaping of special characters.
Fixes three security issues identified in Phase 1.1 code review:
1. JSON injection in parse_json_response() (response_analyzer.sh:113-132)
- Replace heredoc with jq construction using --arg for strings
- Use --argjson for numeric/boolean fields
- Ensures proper escaping of quotes, newlines, backslashes
2. Input validation for --allowed-tools flag (ralph_loop.sh:903-905)
- Add VALID_TOOL_PATTERNS whitelist
- Add validate_allowed_tools() function
- Validate against whitelist in argument parsing
- Allow Bash(...) patterns with any content
3. Shell injection in build_claude_command() (ralph_loop.sh:439-444)
- Convert from string concatenation to command array
- Use global CLAUDE_CMD_ARGS array
- Execute with "${CLAUDE_CMD_ARGS[@]}" instead of bash -c
- No manual escaping needed - array handles metacharacters
All 98 tests passing.
Closes#48, #50
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.

(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

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.
