Novyx Hygiene

Automatic context persistence for Claude Code. One command to install, then it just works.

Your sessions survive /compact, /clear, and restarts — no export, no paste, no manual steps.

---

How It Works

pip install novyx-hygiene
hygiene install

That's it. From now on:

1. Before /compact: Hygiene auto-saves your session (task, decisions, files, git state)
2. After compact/clear/resume: Hygiene injects your context back into Claude automatically
3. On disk: A .claude/hygiene.md file keeps Claude oriented between sessions

No commands to remember. No context to paste. Claude just knows where you left off.

The Problem

Context fills up. You /compact or /clear. Now Claude has amnesia.

The manual workaround:

1. /export to copy everything
2. /clear to reset
3. Paste context back
4. Re-establish where you were
5. Repeat every time

Worse: if compaction hits automatically, you lose context without warning.

Novyx Hygiene makes this automatic.

Commands

hygiene install

Wire up Claude Code hooks. Run once per project (or --user for all projects).

hygiene install          # Project-level (.claude/settings.local.json)
hygiene install --user   # User-level (~/.claude/settings.json)

Installs hooks for:

• PreCompact — auto-save before context compaction
• SessionStart — auto-inject after compact, clear, or resume

hygiene save <task>

Manually save session state. Also auto-writes .claude/hygiene.md.

hygiene save "Building auth flow - JWT login done, registration next"
hygiene save "Refactoring payments" -d "Use Stripe Intents API" -d "Keep backward compat"
hygiene save "Bug fix" -s "Root cause found, writing test"

Options:

• -d / --decision — Record a key decision (repeatable)
• -s / --status — Set status (default: "In progress")
• -i / --session-id — Custom session ID
• --no-md — Skip writing .claude/hygiene.md

hygiene resume [session-id]

Print session context for pasting (useful without hooks installed).

hygiene resume                    # Most recent session
hygiene resume auth-flow-0309     # Specific session

hygiene inject

Emit context to stdout — used by Claude Code hooks internally. You don't need to call this directly.

hygiene score [session-id]

Check context health: freshness, file sprawl, decision tracking, mixed concerns.

$ hygiene score
Context Health: B (80/100)
========================================

Issues:
  - 12 files in flight
  - Changes span 5 top-level directories — possible mixed concerns

Tips:
  - Consider committing completed work before continuing
  - Consider splitting into focused sessions

hygiene list

List all saved sessions.

hygiene list
hygiene list -n 5

hygiene uninstall

Remove hooks.

hygiene uninstall
hygiene uninstall --user

hygiene config

hygiene config set api_key nram_xxx    # Enable cloud sync
hygiene config show

What Gets Saved

Every session snapshot captures:

• Task description — what you're working on
• Key decisions — architectural choices, tradeoffs
• Status — where you left off
• Git state — branch, modified/staged/untracked files, recent commits
• Working directory — so you resume in the right place
• Timestamp — for freshness scoring

---

Cloud Sync (Optional)

By default, sessions are saved locally to ~/.novyx_hygiene/sessions/.

Add a Novyx API key for cloud persistence, semantic search across sessions, and cross-machine sync:

pip install novyx-hygiene[novyx]
hygiene config set api_key nram_your_key_here

---

How Hooks Work

After hygiene install, your .claude/settings.local.json gets:

{
  "hooks": {
    "PreCompact": [
      { "hooks": [{ "type": "command", "command": "hygiene save --auto --quiet", "timeout": 10 }] }
    ],
    "SessionStart": [
      { "matcher": "compact", "hooks": [{ "type": "command", "command": "hygiene inject", "timeout": 5 }] },
      { "matcher": "clear", "hooks": [{ "type": "command", "command": "hygiene inject", "timeout": 5 }] },
      { "matcher": "resume", "hooks": [{ "type": "command", "command": "hygiene inject", "timeout": 5 }] }
    ]
  }
}

• PreCompact hook runs hygiene save --auto before compaction, capturing your current state
• SessionStart hooks run hygiene inject which outputs your last session context to stdout — Claude reads this automatically
• Hooks are additive: they won't overwrite your existing Claude Code hooks
