Session Save — Named Context Checkpoints

Compress current session state → save to named checkpoint file.

Storage

<!-- 📌 НАСТРОЙТЕ: путь к вашему проекту (Claude Code кодирует / как -) -->

~/.claude/projects/<YOUR-PROJECT-PATH>/memory/sessions/
  {name}.md          ← named checkpoints
  _latest.md         ← always points to last saved
~/.claude/projects/<YOUR-PROJECT-PATH>/memory/last-session.md  ← legacy compat

Naming Rules

• If user provides name: use as-is (slug, lowercase, hyphens). Example: vpn-fix, auth-refactor
• If no name: auto-generate from goal. Pattern: {topic}-{MMDD}. Example: insights-0303
• Sanitize: [^a-z0-9-] → -, max 40 chars

Compression Format (InfoCompressor)

Use imperative, terse, scannable style. 40-60% reduction. Zero redundancy.

Template

# Session: {name}
saved: YYYY-MM-DDTHH:MM
context: XX% (XXK tokens)
branch: <git branch>
name: {name}

## Goal
<1-2 sentences: what user wanted to achieve>

## Done
- <completed step 1>
- <completed step 2>

## Pending
- <next step 1>
- <next step 2>

## Modified Files
- `path/to/file1` — what changed
- `path/to/file2` — what changed

## Key Decisions
- <decision 1: chosen → reason>

## Context (carry forward)
<2-5 lines of critical context that next session MUST know>

## Continuation Prompt
<Ready-to-paste prompt for next session to resume work>

Steps

1. Determine name — from argument or auto-generate from goal
2. Analyze session — review conversation history, identify goal/progress/pending
3. Check git — git status, git diff --stat, current branch
4. Compress using InfoCompressor principles:
   • Imperative mood, present tense, active voice
   • 3-7 words per statement
   • → for causality, | for alternatives
   • Cut filler words, state each fact once
5. Write checkpoint to sessions/{name}.md
6. Copy to legacy — also write to last-session.md
7. Save to memory — mcp__memory__add_observations on entity Session-Checkpoint-{name}:
   • goal, done count, pending, files, timestamp
8. Confirm — show:

   ✅ Session saved: {name}
   📁 sessions/{name}.md
   🔄 Resume: /continue {name}
   

Rules

• Never lose: file paths, entity names, error messages, numeric values
• Checkpoint must be self-contained — readable without original session
• Continuation prompt must be specific enough to resume without questions
• Keep under 2KB (aim for 1KB)
• Overwrite existing checkpoint with same name (warn user first)

Context Pressure Auto-Trigger

When context > 50% (🟡 WARNING):

1. Announce: "Context pressure 🟡 — saving checkpoint"
2. Run this skill automatically (auto-generate name)
3. Suggest: "Рекомендую /continue {name} в новой сессии"

When context > 72% (🔴 CRITICAL):

1. Save checkpoint immediately
2. HANDOFF MODE — refuse further execution
3. Write handoff blob
