description: Use when Codex feels slow, bloated, or heavy after heavy use. Provides safe session hygiene, archive strategy, and handoff discipline to keep daily Codex usage responsive and low-friction. Always pairs with comprehensive handoffs before archiving active work.

Codex Fluent

Keep Codex feeling fast, light, and pleasant to use over months of heavy daily work.

This skill is about **operational fluency** — the subjective experience of Codex staying responsive, starting quickly, and not forcing you to fight accumulated context and state.

Core Philosophy

  • Fresh small state = speed and low mental load.
  • Old work must be preserved, but moved out of the active path.
  • **Handoffs are non-negotiable** before archiving anything you might still need.
  • Never delete. Archive with clear restore paths.

When to Use This Skill

  • Codex feels laggy on startup or when switching sessions.
  • You have many long-running or old chats you rarely touch but don't want to lose.
  • Before big maintenance or after noticing session directory growth.
  • After a `codex-retrospective` session where Codex itself flagged repeated context bloat or "I keep having to re-explain the current state".

Safety Rules (Hard)

1. **Inspect first, always.** The first invocation must be report-only. 2. **Handoff before archive.** For any active repo chat you might continue, a high-quality handoff document + reactivation prompt must exist before it is moved to archive. 3. **Backup before mutate.** All changes must be preceded by a timestamped backup. 4. **Archive, never delete.** Sessions, logs, and worktrees are moved to dedicated archive directories (`~/.codex/archived_sessions/`, `archived_worktrees/`, `archived_logs/`). 5. Codex must be closed (or you explicitly accept `--wait-for-codex-exit`) before any filesystem changes to active state. 6. Never touch credentials, global skills you still use, or memory files without explicit confirmation.

Recommended Cadence

  • Heavy daily multi-repo users: weekly report + maintenance when needed.
  • Moderate users: every 10–14 days.
  • The skill can generate a recurring **report-only reminder** prompt for you.

Workflow

1. Diagnosis (Report Mode)

Ask:

Use codex-fluent to inspect my current Codex local state and give me a clear picture of what is causing drag.

The skill will report on:

  • Active vs archived session sizes
  • Largest active sessions and their ages
  • Stale worktrees
  • Large log files
  • Potential thread metadata bloat (title/preview)
  • Dead config entries
  • Heavy background processes (reported only)

2. Handoff Creation (Mandatory for Valuable Work)

Before any archiving of chats you care about, create excellent handoffs.

Use the template in `references/handoff-template.md`.

The reactivation prompt must allow a completely fresh Codex thread (or even Claude via the codex skill) to pick up without the old giant context.

3. Apply Maintenance

Only after handoffs exist for everything important:

Use codex-fluent to perform safe maintenance now. I have created handoffs for the sessions I want to keep continuity on. Codex is closed.

What a normal apply does:

  • Timestamped backup to `~/Documents/Codex/codex-backups/codex-fluent-YYYYMMDD-HHMM/`
  • Move qualifying old sessions to `~/.codex/archived_sessions/`
  • Move stale worktrees to `~/.codex/archived_worktrees/`
  • Rotate oversized logs
  • Clean dead project entries from config
  • Normalize certain path issues where safe

4. Verification

Run diagnosis again and compare before/after sizes and feel.

5. (Optional) Recurring Reminder

Generate a safe, report-only weekly reminder prompt that never applies changes automatically.

Integration with Other Spellbook Skills

  • After running `codex-retrospective`, if Codex complains about "having to re-read huge context every time" or repeated state loss, this skill is the natural follow-up.
  • Design handoff documents as the compact representation of a thread: preserve the objective, constraints, decisions, verification, and unresolved work.
  • Handoff documents created here are excellent material to feed into future `codex-retrospective` runs.

What This Skill Will Not Do

  • Automatically delete anything.
  • Kill processes.
  • Touch credentials or irreplaceable memory.
  • Archive pinned or explicitly marked "do not touch" sessions without confirmation.
  • Promise universal speedups (results depend on your usage patterns).

Gotchas

  • A large session is not automatically safe to archive. If the work is active,

blocked, or likely to resume, create the handoff first and verify that the reactivation prompt points to a real file.

  • Reported size reductions do not prove product speedups by themselves. Compare

before/after active-state size and a fresh startup or session-switch test.

  • Never treat "Codex is closed" as an assumption. If apply mode would touch

active state, verify process state or get explicit user acceptance first.

  • Do not normalize paths, prune config, or move global skills in the same pass

as session archiving unless the diagnosis explicitly named those candidates.

References

  • `references/handoff-template.md` — High-quality handoff document template + reactivation prompt
  • `references/maintenance-checklist.md` — Step-by-step safe maintenance checklist
  • `references/examples/` — Real-world (anonymized) before/after reports and handoff examples

Success Criteria

After using this skill properly you should experience:

  • Noticeably faster Codex startup and session switching
  • Lower anxiety about "losing history"
  • Clear, searchable handoff documents in your important repos
  • A repeatable, low-risk maintenance habit

Start with a diagnosis run. The rest follows naturally.
