# 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 <HARD-GATE> Do NOT propose or implement fixes before completing Steps 1-2 (Scout + Diagnose). Symptom fixes are failure. Find the cause first through structured analysis, NEVER guessing. If 3+ fix attempts fail, STOP and question the architecture — discuss with user before attempting more. User override: `--quick` mode allows fast scout→diagnose→fix cycle for trivial issues (lint, type errors). </HARD-GATE> ## Anti-Rationalization | Thought | Reality | |---------|---------| | "I can see the problem, let me fix it" | Seeing symptoms ≠ understanding root cause. Scout first. | | "Quick fix for now, investigate later" | "Later" never comes. Fix properly now. | | "Just try changing X" | Random fixes waste time and create new bugs. Diagnose first. | | "It's probably X" | "Probably" = guessing. Use structured diagnosis. Verify first. | | "One more fix attempt" (after 2+) | 3+ failures = wrong approach. Question architecture. | | "Emergency, no time for process" | Systematic diagnosis is FASTER than guess-and-check. | | "I already know the codebase" | Knowledge decays. Scout to verify assumptions before acting. | | "The fix is done, tests pass" | Without prevention, same bug class will recur. Add guards. | ## Process Flow (Authoritative) ```mermaid flowchart TD A[Issue Input] --> B[Step 0: Mode Selection] B --> C[Step 1: Scout - Understand Context] C --> D[Step 2: Diagnose - Structured Root Cause Analysis] D --> E[Step 3: Complexity Assessment + Task Orchestration] E -->|Simple| F[Quick Workflow] E -->|Moderate| G[Standard Workflow] E -->|Complex| H[Deep Workflow] E -->|Parallel| I[Multi-Agent Fix] F --> J[Step 4: Fix Implementation] G --> J H --> J I --> J J --> K[Step 5: Verify + Prevent] K -->|Pass + Prevention in place| L[Step 6: Finalize] K -->|Fail, <3 attempts| D K -->|Fail, 3+ attempts| M[Question Architecture] M --> N[Discuss with User] L --> O[Report + Docs + Journal] ``` **This diagram is the authoritative workflow.** If prose conflicts with this flow, follow the diagram. ## Workflow ### Step 0: Mode Selection **First action:** If there is no "auto" keyword in the request, use `AskUserQuestion` 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 scout → diagnose → fix → review cycle | See `references/mode-selection.md` for AskUserQuestion format. ### Step 1: Scout (MANDATORY — never skip) **Purpose:** Understand the affected codebase BEFORE forming any hypotheses. **Mandatory skill chain:** 1. Activate `ck:scout` skill OR launch 2-3 parallel `Explore` subagents 2. Discover: affected files, dependencies, related tests, recent changes (`git log`) 3. Read `./docs` for project context if unfamiliar **Quick mode:** Minimal scout — locate affected file(s) and their direct dependencies only. **Standard/Deep mode:** Full scout — map module boundaries, test coverage, call chains. **Output:** `✓ Step 1: Scouted - [N] files mapped, [M] dependencies, [K] tests found` ### Step 2: Diagnose (MANDATORY — never skip) **Purpose:** Structured root cause analysis. NO guessing. Evidence-based only. **Mandatory skill chain:** 1. **Capture pre-fix state:** Record exact error messages, failing test output, stack traces, log snippets. This becomes the baseline for Step 5 verification. 2. Activate `ck:debug` skill (systematic-debugging + root-cause-tracing techniques). 3. Activate `ck:sequential-thinking` skill — form hypotheses through structured reasoning, NOT guessing. 4. Spawn parallel `Explore` subagents to test each hypothesis against codebase evidence. 5. If 2+ hypotheses fail → auto-activate `ck:problem-solving` skill for alternative approaches. 6. Create diagnosis report: confirmed root cause, evidence chain, affected scope. See `references/diagnosis-protocol.md` for full methodology. **Output:** `✓ Step 2: Diagnosed - Root cause: [summary], Evidence: [brief], Scope: [N files]` ### 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, create native Claude Tasks for all phases upfront with dependencies. See `references/task-orchestration.md`. - Skip for Quick workflow (< 3 steps, overhead exceeds benefit) - Use `TaskCreate` with `addBlockedBy` for dependency chains - Update via `TaskUpdate` as each phase completes - For Parallel: create separate task trees per independent issue - **Fallback:** Task tools (`TaskCreate`/`TaskUpdate`/`TaskGet`/`TaskList`) are CLI-only — unavailable in VSCode extension. If they error, use `TodoWrite` for progress tracking. Fix workflow remains fully functional without them. ### Step 4: Fix Implementation - Implement fix per selected workflow, updating Tasks as phases complete. - Follow diagnosis findings — fix the ROOT CAUSE, not symptoms. - Minimal changes only. Follow existing patterns. ### Step 5: Verify + Prevent (MANDATORY — never skip) **Purpose:** Prove the fix works AND prevent the same bug class from recurring. **Mandatory skill chain:** 1. **Verify (iron-law):** Run the EXACT commands from pre-fix state capture. Compare output. NO claims without fresh evidence. 2. **Regression test:** Add or update test(s) that specifically cover the fixed issue. The test MUST fail without the fix and pass with it. 3. **Prevention gate:** Apply defense-in-depth validation where applicable. See `references/prevention-gate.md`. 4. **Parallel verification:** Launch `Bash` agents for typecheck + lint + build + test. **If verification fails:** Loop back to Step 2 (re-diagnose). After 3 failures → question architecture, discuss with user. See `references/prevention-gate.md` for prevention requirements. **Output:** `✓ Step 5: Verified + Prevented - [before/after comparison], [N] tests added, [M] guards added` ### Step 6: Finalize (MANDATORY — never skip) 1. Report summary: confidence score, root cause, changes, files, prevention measures 2. `docs-manager` subagent → update `./docs` if changes warrant (NON-OPTIONAL) 3. `TaskUpdate` → mark ALL Claude Tasks `completed` (skip if Task tools unavailable) 4. Ask user if they want to commit via `git-manager` subagent 5. Run `/ck:journal` to write a concise technical journal entry upon completion --- ## IMPORTANT: Skill/Subagent Activation Matrix See `references/skill-activation-matrix.md` for complete matrix. **Always activate (ALL workflows):** - `ck:scout` (Step 1) — understand before diagnosing - `ck:debug` (Step 2) — systematic root cause investigation - `ck:sequential-thinking` (Step 2) — structured hypothesis formation **Conditional:** - `ck:problem-solving` — auto-triggers when 2+ hypotheses fail in Step 2 - `ck:brainstorm` — multiple valid approaches, architecture decision (Deep only) - `ck:context-engineering` — fixing AI/LLM/agent code - `ck:project-management` — moderate+ for task hydration/sync-back **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 ✓ Step 1: Scouted - [N] files, [M] deps ✓ Step 2: Diagnosed - Root cause: [summary] ✓ Step 3: [Complexity] detected - [workflow] selected ✓ Step 4: Fixed - [N] files changed ✓ Step 5: Verified + Prevented - [tests added], [guards added] ✓ Step 6: Complete - [action taken] ``` ## References Load as needed: - `references/mode-selection.md` - AskUserQuestion format for mode - `references/diagnosis-protocol.md` - Structured diagnosis methodology (NEW) - `references/prevention-gate.md` - Prevention requirements after fix (NEW) - `references/complexity-assessment.md` - Classification criteria - `references/task-orchestration.md` - Native Claude Task patterns for moderate+ workflows - `references/workflow-quick.md` - Quick: scout → diagnose → fix → verify+prevent → review - `references/workflow-standard.md` - Standard: full pipeline with Tasks - `references/workflow-deep.md` - Deep: research + brainstorm + plan with Tasks - `references/review-cycle.md` - Review logic (autonomous vs HITL) - `references/skill-activation-matrix.md` - When to activate each skill - `references/parallel-exploration.md` - Parallel Explore/Bash/Task coordination patterns **Specialized Workflows:** - `references/workflow-ci.md` - GitHub Actions/CI failures - `references/workflow-logs.md` - Application log analysis - `references/workflow-test.md` - Test suite failures - `references/workflow-types.md` - TypeScript type errors - `references/workflow-ui.md` - Visual/UI issues (requires design skills)
