Beta Feedback Fixer Skill

What This Skill Does

This skill automates the workflow for systematically fixing issues identified in beta tester feedback. It guides you through:

• Parsing structured beta testing reports
• Classifying issues by severity (P0/P1/P2)
• Performing root cause analysis
• Creating isolated worktrees for fixes
• Implementing fixes with regression tests
• Preparing next beta releases

Core principle: Fix issues systematically with proper isolation, testing, and documentation.

When to Use This Skill

Activate this skill when:

• User provides a beta testing report with identified issues
• User asks to "fix beta feedback" or "resolve P0 issues"
• User wants to systematically address tester complaints
• User has a list of bugs from QA/testing cycles
• User needs to prepare the next beta release after fixes

Example triggers:

• "Fix these P0 issues from beta testing"
• "Address the beta tester feedback"
• "Resolve these critical bugs: [list]"
• "Prepare beta.2 with these fixes"

Core Workflow

Phase 1: Report Parsing & Issue Extraction

Parse structured beta testing reports and extract actionable issues.

Supported formats:

• Markdown reports (

  .claude/releases/BETA-*-REPORT.md

  )
• YAML test results
• GitHub issue lists
• Plain text with structured sections

Extract for each issue:

• Issue ID (if available)
• Title/description
• Severity/priority
• Expected behavior
• Actual behavior
• Reproduction steps
• Category (bug, docs, performance, etc.)

Output: Issue list with metadata

Example:

## Extracted Issues

### Issue #402: Telemetry prompt spam (P0)
- **Category**: Bug - Config persistence
- **Expected**: Prompt shows once, persists choice
- **Actual**: Prompt shows on every command
- **Repro**: Run `caro "list files"` twice

Phase 2: Severity Classification

Classify each issue by severity using this framework:

P0 (Critical) - Blocks release:

• Security vulnerabilities
• Data loss or corruption
• Complete feature breakage
• Unusable core functionality
• Output format corruption (JSON/YAML)

P1 (High) - Significant impact:

• Major UX degradation
• Performance regression >50%
• Missing critical features
• Workaround exists but difficult

P2 (Medium) - Minor impact:

• Cosmetic issues
• Documentation errors
• Minor UX annoyances
• Non-critical missing features

Triage rules:

1. Fix P0 issues first (required for release)
2. Group related issues (shared root cause)
3. Address P1 if time permits
4. Defer P2 to future releases

Phase 3: Root Cause Analysis

For each issue, perform systematic root cause analysis:

Step 1: Locate relevant code

# Search for error messages
grep -r "error message text" src/

# Find relevant modules
find src/ -name "*telemetry*" -o -name "*config*"

# Check recent changes
git log --oneline --since="2 weeks ago" -- src/main.rs

Step 2: Trace execution path

• Add logging if needed
• Follow code flow from user action to bug
• Identify the exact line where behavior diverges

Step 3: Identify root cause category

Use these categories:

1. Empty Implementation (empty TODO branches)

   • Code path exists but not implemented
   • Example: Consent prompt result captured but never saved

2. Missing Config Persistence

   • User preferences not saved to disk
   • Config loaded but not written back

3. Pattern Matching Issues

   • Static patterns in wrong order (specific after general)
   • Regex too broad or too narrow
   • Missing required pattern

4. Output Format Awareness

   • Interactive prompts in non-interactive mode
   • Writing to stdout instead of stderr

5. Documentation Mismatch

   • Docs claim feature doesn't exist
   • Examples show wrong syntax

Step 4: Document findings

Use the root cause template (see

templates/root-cause-template.md

).

Phase 4: Worktree Creation

Create an isolated environment for fixes:

# Create worktree
git worktree add .worktrees/fix-beta-X-p0-issues -b fix/beta-X-p0-issues

# Navigate to worktree
cd .worktrees/fix-beta-X-p0-issues

# Verify clean baseline
cargo test

Branch naming convention:

fix/beta-X-p0-issues

• X = beta version number (1, 2, 3)
• Use "p0" for critical fixes, "p1" for high priority

Phase 5: Implementation & Testing

Fix issues systematically with regression tests:

For each issue:

1. Write regression test first (TDD approach)

   #[tokio::test]
   async fn test_issue_402_telemetry_persistence() {
       // Setup: Fresh config
       let config_path = temp_config();
   
       // Execute: Run command twice
       run_command("list files", &config_path);
       run_command("list files", &config_path);
   
       // Assert: Config saved, first_run=false
       let config = load_config(&config_path);
       assert_eq!(config.telemetry.first_run, false);
   }
   

2. Implement the fix

   • Minimal change to fix the root cause
   • Preserve existing behavior
   • Add comments explaining the fix

3. Verify fix works

   # Run regression test
   cargo test test_issue_402
   
   # Run full test suite
   cargo test
   
   # Manual verification
   caro "list files"  # First run
   caro "list files"  # Should not show prompt
   

4. Commit atomically

   git add src/main.rs tests/beta_regression.rs
   git commit -m "fix(telemetry): Persist consent choice to config
   
   Fixes: #402, #403
   
   Root cause: Config was loaded but never saved after consent.
   Added config_manager.save() call after updating first_run flag.
   
   Regression test: test_issue_402_telemetry_persistence"
   

Fix priority: P0 first, then P1, then P2

Commit granularity: One logical fix per commit (may fix multiple related issues)

Phase 6: PR & Release Preparation

After all fixes are implemented:

1. Create comprehensive PR

Use this template:

## Summary

Fixes all X critical P0 issues from beta.Y testing.

**Fixes**: #402, #403, #404, #405, #406

## Issues Fixed

### Issue #402 & #403: [Title]
- ✅ FIXED: [What now works]
- Root cause: [Brief explanation]
- Fix: [What was changed]

[Repeat for each issue]

## Test Coverage

### Regression Tests
- ✅ test_issue_402_...
- ✅ test_issue_403_...

All X tests pass ✅

### Full Test Suite
- ✅ Y library tests pass
- ✅ No regressions

## Impact

**Before**: [Metrics/behavior]
**After**: [Metrics/behavior]

## Manual Verification

```bash
# Steps to manually verify fixes

**2. Bump version for next beta**

```bash
# Update Cargo.toml
version = "1.1.0-beta.X"

# Update CHANGELOG.md
## [1.1.0-beta.X] - YYYY-MM-DD

### Fixed
- Issue #402: [description]
- Issue #403: [description]
...

# Create git tag
git tag -a v1.1.0-beta.X -m "Release beta.X - Critical fixes"

# Push
git push origin fix/beta-Y-p0-issues
git push origin v1.1.0-beta.X

3. Create beta testing instructions

Update

.claude/releases/BETA-TESTING-INSTRUCTIONS-vX.md

:

• Document what was fixed
• Create focused test plan for verifying fixes
• Include regression testing checklist

Common Root Cause Patterns

Based on real beta testing experience, watch for these patterns:

1. Empty TODO Branches

Symptom: Code path exists but does nothing Location: if/else with TODO comments Fix: Implement the missing logic

// BEFORE (broken)
if user_config.telemetry.first_run {
    if prompt_consent() {
        // TODO: Save config
    }
}

// AFTER (fixed)
if user_config.telemetry.first_run {
    let consent = prompt_consent();
    user_config.telemetry.enabled = consent;
    user_config.telemetry.first_run = false;
    config_manager.save(&user_config)?;
}

2. Pattern Ordering Issues

Symptom: Wrong command generated, generic instead of specific Location: Static pattern matcher Fix: Move specific patterns before general patterns

// BEFORE (wrong order)
Pattern 1: "files modified" (3 keywords)
Pattern 46: "python files modified" (4 keywords)

// AFTER (correct order)
Pattern 1: "python files modified" (4 keywords - specific)
Pattern 2: "files modified" (3 keywords - general)

3. Missing Config Persistence

Symptom: User settings don't persist across runs Location: Config loading without saving Fix: Call save() after updating config

4. Output Format Awareness

Symptom: Interactive prompts pollute JSON/YAML output Location: Prompts run unconditionally Fix: Skip interactive prompts when output format is machine-readable

// BEFORE (broken)
prompt_consent();  // Always runs

// AFTER (fixed)
let is_interactive = matches!(cli.output, None | Some(OutputFormat::Plain));
if is_interactive {
    prompt_consent();
}

5. Documentation Drift

Symptom: Docs claim feature doesn't exist when it does Location: Beta testing instructions, README Fix: Update docs to match reality
