Ck:fix

Fixing

Unified skill for fixing issues of any complexity with intelligent routing.

Arguments

• --auto - Activate autonomous mode (default)
• --review - Activate human-in-the-loop review mode
• --quick - Activate quick mode
• --parallel - Activate parallel mode: route to parallel fullstack_developer agents per issue

Workflow

Step 1: Mode Selection

First action: If there is no "auto" keyword in the request, ask the user to determine workflow mode:

| Option | Recommend When | Behavior | |--------|----------------|----------| | Autonomous (default) | Simple/moderate issues | Auto-approve if score >= 9.5 & 0 critical | | Human-in-the-loop Review | Critical/production code | Pause for approval at each step | | Quick | Type errors, lint, trivial bugs | Fast debug → fix → review cycle |

See references/mode-selection.md for the mode-selection prompt format.

Step 2: Debug

• Activate ck:debug skill.
• Guess all possible root causes.
• Prefer multiple Explore/scout agents in parallel to verify each hypothesis when the runtime exposes delegation; otherwise use parallel searches and report the limitation.
• Create report with all findings for the next step.

Step 3: Complexity Assessment & Task Orchestration

Classify before routing. See references/complexity-assessment.md.

| Level | Indicators | Workflow | |-------|------------|----------| | Simple | Single file, clear error, type/lint | references/workflow-quick.md | | Moderate | Multi-file, root cause unclear | references/workflow-standard.md | | Complex | System-wide, architecture impact | references/workflow-deep.md | | Parallel | 2+ independent issues OR --parallel flag | Parallel fullstack_developer agents |

Task Orchestration (Moderate+ only): After classifying, use available task-tracking tools for all phases upfront with dependencies. See references/task-orchestration.md.

• Skip for Quick workflow (< 3 steps, overhead exceeds benefit)
• Create tracked tasks with dependency chains when task tools exist
• Update task/checklist state as each phase completes
• For Parallel: create separate task trees per independent issue

Step 4: Fix Implementation & Verification

• Implement fix per selected workflow, updating Tasks as phases complete.
• Prefer multiple scout agents to verify no regressions when available.
• Prevent future issues by adding comprehensive validation.

Step 5: Finalize (MANDATORY - never skip)

1. Report summary: confidence score, changes, files
2. Prefer docs_manager subagent → update the configured docs path if changes warrant
3. Update task state/checklists and mark all tracked tasks completed
4. Ask user if they want to commit via git_manager subagent

IMPORTANT: Skill/Subagent Activation Matrix

See references/skill-activation-matrix.md for complete matrix.

Always activate: ck:debug (all workflows) Conditional: ck:problem-solving, ck:sequential-thinking, ck:brainstorm, ck:context-engineering Subagents: debugger, researcher, planner, code_reviewer, tester, Bash Parallel: Multiple Explore agents for scouting, Bash agents for verification

Output Format

Unified step markers:

✓ Step 0: [Mode] selected - [Complexity] detected
✓ Step 1: Root cause identified - [summary]
✓ Step 2: Fix implemented - [N] files changed
✓ Step 3: Tests [X/X passed]
✓ Step 4: Review [score]/10 - [status]
✓ Step 5: Complete - [action taken]
