Session Logger

A skill for automatically saving conversation history to persistent session log files.

When This Skill Activates

This skill activates when you:

• Say "保存对话信息" or "保存对话"
• Say "记录会话内容" or "保存session"
• Say "save session" or "save conversation"
• Ask to save the current conversation

Session File Location

All sessions are saved to: sessions/YYYY-MM-DD-{topic}.md

What Gets Logged

For each session, log:

1. Metadata

   • Date and duration
   • Context/working directory
   • Main topic

2. Summary

   • What was accomplished
   • Key decisions made
   • Files created/modified

3. Actions Taken

   • Checklist of completed tasks
   • Pending follow-ups

4. Technical Notes

   • Important code snippets
   • Commands used
   • Solutions found

5. Open Questions

   • Issues to revisit
   • Follow-up tasks

Session Template

# Session: {Topic}

**Date**: {YYYY-MM-DD}
**Duration**: {approximate}
**Context**: {project/directory}

## Summary

{What was accomplished in this session}

## Key Decisions

1. {Decision 1}
2. {Decision 2}

## Actions Taken

- [x] {Completed action 1}
- [x] {Completed action 2}
- [ ] {Pending action 3}

## Technical Notes

{Important technical details}

## Open Questions / Follow-ups

- {Question 1}
- {Question 2}

## Related Files

- `{file-path}` - {what changed}

How to Use

Option 1: Automatic Logging

Simply say:

"保存对话信息"

The skill will:

1. Review the conversation history
2. Extract key information
3. Create/update the session file

Option 2: With Topic

Specify the session topic:

"保存对话，主题是 skill-router 创建"

Option 3: Manual Prompt

If auto-extraction misses something, provide details:

"保存对话，重点是：1) 创建了 skill-router，2) 修复了 front matter"

File Naming

Input	Filename
"保存对话"	YYYY-MM-DD-session.md
"保存对话，主题是 prd"	YYYY-MM-DD-prd.md
"保存今天的讨论"	YYYY-MM-DD-discussion.md

Session Log Structure

sessions/
├── README.md                      # This file
├── 2025-01-11-skill-router.md     # Session about skill-router
├── 2025-01-11-prd-planner.md      # Session about PRD planner
└── 2025-01-12-refactoring.md      # Session about refactoring

Privacy Note

Session logs are stored in sessions/ which is in .gitignore.

• Logs are NOT committed to git
• Logs contain your actual conversation
• Safe to include sensitive information

Quick Reference

You say	Skill does
"保存对话信息"	Creates session log with today's date
"保存今天的对话"	Creates session log
"保存session"	Creates session log
"记录会话"	Creates session log

Best Practices

1. Save at key milestones: After completing a feature, fixing a bug, etc.
2. Be specific with topics: Helps when searching later
3. Include code snippets: Save important solutions
4. Track decisions: Why did you choose X over Y?
5. List pending items: What to do next time

Rich Content Extraction (for Self-Improving Agent)

When triggered by other skills via hooks, session-logger extracts structured data for learning:

Skill Context Capture

When a skill completes, capture:

## Skill Execution Context

**Skill**: {skill-name}
**Trigger**: {user-invoked | hook-triggered | auto-triggered}
**Status**: {completed | error | partial}
**Duration**: {approximate time}

### Input Context
- User request: {original request}
- Files involved: {list of files}
- Codebase patterns detected: {patterns}

### Output Summary
- Actions taken: {list}
- Files modified: {list with changes}
- Decisions made: {key decisions}

### Learning Signals
- What worked well: {successes}
- What could improve: {areas for improvement}
- Patterns discovered: {new patterns}
- Errors encountered: {errors and resolutions}

Error Context Capture

When a skill encounters errors:

## Error Context

**Error Type**: {type}
**Error Message**: {message}
**Stack Trace**: {if available}

### Resolution Attempted
- Approach: {what was tried}
- Result: {success/failure}
- Root cause: {if identified}

### Prevention Notes
- How to avoid: {prevention strategy}
- Related patterns: {similar issues}

Pattern Extraction

Extract reusable patterns for the self-improving-agent:

## Extracted Patterns

### Code Patterns
- Pattern name: {name}
- Context: {when to use}
- Example: {code snippet}

### Workflow Patterns
- Trigger: {what initiates}
- Steps: {sequence}
- Outcome: {expected result}

### Anti-Patterns
- Pattern: {what to avoid}
- Why: {reason}
- Alternative: {better approach}

Structured Data Format

For machine-readable extraction, use YAML front matter in session logs:

---
session_type: skill_execution
skill_name: code-reviewer
trigger_source: hook
status: completed
files_modified:
  - path: src/utils.ts
    changes: refactored error handling
patterns_learned:
  - name: error-boundary-pattern
    category: error-handling
    confidence: high
errors_encountered: []
learning_signals:
  successes:
    - "Identified code smell in utils.ts"
  improvements:
    - "Could have suggested more specific refactoring"
---

Integration with Self-Improving Agent

When triggered by self-improving-agent:

1. Extract episodic memory: Capture the full context of what happened
2. Identify semantic patterns: Tag reusable knowledge
3. Update working memory: Note immediate follow-ups needed
4. Signal completion: Write trigger file if skill chaining is needed

Auto-Trigger Behavior

When invoked via hooks with mode: auto:

• Silently create/update session log
• Extract structured data without user interaction
• Append to existing session if same day/topic
• Create new session if context differs significantly
