compact-plus

In Claude Code, the PreCompact hook automatically saves a pre-compaction state file when /compact runs. Codex does not run that hook, so this skill can be used as a manual fallback when needed.

Before Claude Code /compact, save working state that is not reliably preserved by the compaction summary to ${TMPDIR}/claude-compact-state/${SESSION_ID}.md.

Strict procedure profile

• Strictness: strict-procedure. The state file content and completion receipt are the deliverable.
• Hard gates: if the session id cannot be detected, do not create a guessed state file name. Stop and report that session id detection failed.
• Forcing function: fix the destination path, then read the saved file back and verify that the required headings exist.
• Completion receipt: report the state file path, main saved items, unverified items, and the instruction to run /compact.

Procedure

1. Get the session id.
   • Run ${CLAUDE_PLUGIN_ROOT}/scripts/get-session-id.sh.
   • If it cannot be detected, do not create a state file. Report that preparation is incomplete because the session id is unavailable.
2. Set the destination to ${TMPDIR:-/tmp}/claude-compact-state/${SESSION_ID}.md.
3. Check TaskList, active plan file, tmux-bridge state, and files currently being edited.
   • Read the relevant active plan file under ~/.claude/plans/ when one is present.
   • If tmux-bridge is not used, record Not used.
4. Save the following headings to the state file in this exact order.

# Compact Prep State
## Active Plan
## Current Phase
## TaskList Summary
## Session Decisions
## Constraints and Blockers
## Worker Topology
## Skills Invoked
## Editing Files
## Failed Attempts
## Recovery Notes

5. Read the state file back after saving and verify that every heading above exists.
6. Tell the user: Preparation complete. Please run /compact.

Content To Save

• Active plan file path and current phase or step.
• In-progress task list and relevant notes.
• Decisions made during the session, user choices, and rejected alternatives with rationale.
• Constraints, blockers, and incomplete verification.
• Worker topology. When tmux-bridge is used, record pane, role, and responsibility.
• Skills and slash commands invoked earlier in the session. This is an invocation record, not proof that the skill or command is currently active.
• Files being edited and notes about unsaved or unverified work.
• Failed attempts, tool errors, and rejected approaches that should not be repeated.
• Recovery notes for the post-compaction agent.

Completion receipt

Include the following when complete:

• State file path.
• Main saved items.
• Unverified items and reasons.
• Preparation complete. Please run /compact.
