# Enhanced Intelligent Session Handoff Command

You are concluding work on the current project and need to create a **comprehensive cognitive handoff** for the next AI session. This command performs deep analysis of your session to capture not just what was done, but the complete mental state, reasoning, and context needed for seamless continuation.

## Auto-Loaded Project Context:
@docs/ai-context/HANDOFF.md (if exists)
@/CLAUDE.md
@/README.md (if exists)
@/package.json or requirements.txt or similar (if exists)

## Philosophy of Perfect Handoff

A perfect handoff enables the next session to:
- **Resume instantly** without re-learning context
- **Avoid repeating failed approaches** by understanding what didn't work
- **Continue the exact train of thought** from where it stopped
- **Make informed decisions** based on the full context of choices made

## Step 1: Deep Session Analysis - Evidence Collection

Perform exhaustive analysis of the current session to identify ALL significant work and context:

### 1.1 File Operations Analysis
Examine ALL file operations from this session:
- **Files Created**: New files and their purpose in the system
- **Files Modified**: What changed and why (not just that they changed)
- **Files Deleted**: What was removed and the reasoning
- **Files Read/Analyzed**: Even files examined but not modified (shows investigation paths)

For each significant file operation, capture:
- The specific changes made (function added, logic modified, configuration changed)
- The reason for the change (bug fix, feature addition, refactoring, performance)
- Any alternative approaches considered but rejected
- Related files that might need future changes

### 1.2 Command Execution Analysis
Review all bash/shell commands executed:
- **Installation commands**: Dependencies added or removed
- **Build/compilation commands**: What was built and results
- **Test commands**: What was tested and outcomes
- **Database commands**: Schema changes, queries, migrations
- **Git operations**: Commits, branches, merges attempted
- **Debug commands**: Inspection tools used (grep, find, logs examined)

For each significant command, document:
- The command itself (exact syntax for reproduction)
- Why it was run (the problem it addressed)
- The output/result obtained
- Whether it succeeded or failed and why

### 1.3 Problem-Solving Journey
Reconstruct the cognitive path of this session:
- **Initial Problem Statement**: What was the starting goal or issue?
- **Hypotheses Formed**: What did you think might be causing the issue?
- **Approaches Attempted**: What solutions were tried in order?
  - Approach 1: [Description] → [Outcome] → [Why it failed/succeeded]
  - Approach 2: [Description] → [Outcome] → [Why it failed/succeeded]
  - Continue for all attempts...
- **Key Insights Discovered**: "Aha!" moments that changed understanding
- **Current Working Theory**: What you now believe is the truth about the system

### 1.4 Code Patterns and Conventions Observed
Document patterns discovered in this project:
- **Naming Conventions**: How variables, functions, files are named
- **Architecture Patterns**: MVC, microservices, component structure used
- **Error Handling Approach**: Try-catch patterns, error propagation style
- **Testing Conventions**: Test file locations, naming, structure
- **Configuration Patterns**: How config is loaded, environment variables used
- **Import/Dependency Patterns**: How modules are imported and organized

### 1.5 Dependencies and Relationships Mapped
Create a mental map of interconnections:
- **File Dependencies**: Which files import/require which others
- **Function Call Chains**: Key execution flows through the codebase
- **Data Flow**: How data moves through the system
- **Configuration Dependencies**: What config affects what behavior
- **External Dependencies**: Third-party libraries and their roles

### 1.6 Testing State Snapshot
Capture the complete testing situation:
- **Tests That Pass**: What functionality is verified working
- **Tests That Fail**: What's broken and error messages
- **Tests Not Yet Written**: Functionality lacking test coverage
- **Manual Testing Performed**: User actions tested and results
- **Edge Cases Discovered**: Unusual scenarios found during testing

### 1.7 User-Provided Context Integration
Process the user's description: "$ARGUMENTS"

Interpret this context and integrate it with auto-detected evidence:
- Does user context reveal intent not obvious from file changes?
- Does it explain why certain approaches were taken?
- Does it highlight priorities for next steps?
- Does it mention blockers or concerns not visible in code?

## Step 2: Extract Decision Rationale

For every significant decision made in this session, document:

### 2.1 Technical Decisions
- **What was decided**: The specific technical choice made
- **Alternatives considered**: Other options that were evaluated
- **Reasoning**: Why this choice over alternatives (performance, maintainability, simplicity, standards-compliance)
- **Trade-offs accepted**: What was sacrificed for this decision
- **Future implications**: How this decision constrains or enables future work

### 2.2 Architectural Decisions
- **Structure chosen**: How code/components are organized
- **Rationale**: Why this structure serves the project goals
- **Constraints respected**: Existing patterns that influenced this choice
- **Extensibility considerations**: How future features can fit in

### 2.3 Priority Decisions
- **What was prioritized**: Which work was done first and why
- **What was deferred**: Work postponed and the reason
- **Trade-offs**: Why some things were left incomplete

## Step 3: Identify Knowledge Gaps and Uncertainties

Capture what is NOT yet known or understood:

### 3.1 Unresolved Questions
- Technical questions that remain unanswered
- Behavior that's unclear or needs verification
- Documentation that's ambiguous or contradictory

### 3.2 Assumptions Made
- What was assumed to be true (but not verified)
- Why these assumptions were necessary
- How to validate them later

### 3.3 Areas Needing Investigation
- Code areas that haven't been fully understood
- Dependencies whose behavior is uncertain
- Performance characteristics that haven't been measured

## Step 4: Compile Failed Attempts Database

Document what DIDN'T work (crucial to avoid repetition):

### 4.1 Failed Approaches
For each approach that failed:
- **What was tried**: Exact description of the attempt
- **Why it seemed promising**: The logic that made it worth trying
- **How it failed**: Specific error or incorrect behavior
- **Root cause**: Why it didn't work (if understood)
- **Lesson learned**: Insight gained from the failure

### 4.2 Dead Ends Explored
- Investigation paths that led nowhere
- Code sections examined that turned out to be irrelevant
- Documentation that was misleading

### 4.3 Gotchas Discovered
- Surprising behavior of libraries or frameworks
- Subtle bugs or edge cases found
- Configuration pitfalls encountered

## Step 5: Generate Actionable Next Steps

Create ultra-specific next steps with maximal context:

### 5.1 Immediate Next Actions
For each next action, provide:
- **Clear objective**: What should be accomplished
- **Exact steps**: Numbered procedure to follow
  1. Open file `[exact/path/to/file.ext]`
  2. Locate function/section `[specific identifier]`
  3. Modify by `[precise description]`
  4. Test by running `[exact command]`
  5. Expected result: `[what should happen]`
- **Required context**: What needs to be understood first
- **Success criteria**: How to know it's complete
- **Estimated complexity**: Time/effort expectation

### 5.2 Dependency Chain
Order actions by dependencies:
- **Prerequisites**: What must be done first
- **Parallel work**: What can be done simultaneously
- **Sequential requirements**: What must follow what

### 5.3 Validation Strategy
- How to verify each step worked
- Tests to run and expected outputs
- Manual checks to perform

## Step 6: Analyze and Update HANDOFF.md

Load and analyze the existing `docs/ai-context/HANDOFF.md`:

### 6.1 Understand Current Structure
- Identify all existing sections and their status
- Note any ongoing work that relates to this session
- Observe formatting and organization patterns
- Find any TODOs or open items

### 6.2 Determine Update Strategy

**If work relates to existing section:**

- Modify "Failed Approaches" if new failures occurred
- Revise "Next Steps" based on new progress
- Update "Testing State" with new results

**If work is new/unrelated:**
- Create new section with current timestamp
- Use enhanced structure (see Step 7)
- Maintain consistency with existing document style

**If work completed existing task:**
- Mark task as [COMPLETED] with completion date
- Summarize final outcome and learnings
- Move to "Completed Work" archive section if it exists
- Update any dependent tasks that can now proceed

## Advanced Tips for Perfect Handoff

**Capture the "Why" not just the "What":**
Every action has reasoning. Document it. Future you (or next AI) needs to understand the thought process, not just the result.

**Failed approaches are valuable:**
Don't hide failures. They're learning opportunities and prevent wasted effort repeating the same mistakes.

**Be specific with file paths:**
"Updated the config file" is useless. "`config/database.json` - Changed connection pool size from 10 to 50 to handle increased load" is gold.

**Make next steps actionable:**
"Fix the bug" is vague. "In `src/auth/login.ts` line 45, add null check before accessing user.email because registration flow can create users without email when using OAuth" is actionable.

**Document your mental model:**
Explain how you understand the system working. Your mental model is what enables quick decisions. Share it.

**Preserve context for decisions:**
When you choose approach A over B, explain why. Future work might change the constraints, and knowing why B was rejected helps re-evaluate.

**Note code patterns explicitly:**
Every codebase has unwritten conventions. Write them down. It speeds up all future work.

**Include validation steps:**
For every change, note how to verify it worked. This enables confident progress and quick debugging.

Now execute this enhanced handoff process, integrating user context "$ARGUMENTS" with your deep session analysis.
