Jww Codex Maintenance

Maintain Codex Local State

Xcode Availability

This skill is unavailable in Xcode. Its procedure depends on Codex Desktop or CLI local state and supported Codex task-management operations, which Xcode does not provide. Use it only in a Codex harness.

Separate diagnosis from cleanup. Large local state can correlate with a slow app, but do not treat file size as proof of the cause or promise a speedup.

Never

• Simulate archival by moving session JSONL files or editing the local-state database.
• Vacuum, rebuild, edit, or replace a Codex database without an explicit repair request backed by an official procedure.
• Kill background processes, language servers, or dev servers. Report them and let the user decide.
• Copy transcripts, logs, memories, config, databases, or credentials to a repository, shared folder, or cloud-synced location without explicit approval.
• Mutate live Codex files on a schedule.

Select the Mode

Default to Audit. Switch only on an explicit request: the user says "clean up", "rotate", "archive", or "delete" for Apply; "schedule" or "recurring report" for Automate. Treat "make Codex faster" as an audit request, not permission to mutate state.

• Audit: inspect and report without changing tasks, files, configuration, processes, or scheduled tasks.
• Apply: read references/apply.md, resolve the exact targets, and perform only the cleanup authorized by the user's request. When the request authorizes a category but not distinguishable targets within it, present those targets and obtain approval before changing them.
• Automate: create a recurring read-only audit and report. Read references/automation.md before scheduling.

If the request is ambiguous, complete the audit and stop with a proposed cleanup set.

Inventory the Current State

1. Resolve CODEX_HOME from the environment when it is set; otherwise use ~/.codex. Do not redefine HOME, CODEX_HOME, or another common system variable in shell commands.
2. Determine whether the desktop app, Codex CLI, scheduled runs, or other Codex processes are active. Report them; do not stop them automatically.
3. Record sizes, file counts, oldest and newest modification times, and largest files for:
   • active and archived session transcripts
   • Codex and desktop-app logs
   • app-managed and Git worktrees
   • configuration and profile files
   • local databases and their -wal and -shm sidecars
   • memories, skills, plugins, and scheduled-task metadata when present
4. Use host-supported task operations to list task status, pinning, age, and project association when available. Do not infer pinning or task state by rewriting an index or querying an undocumented database schema.
5. Inspect heavy development processes, especially long-lived language servers and dev servers, but report their command, working directory, age, and memory use instead of killing them.

On macOS, include ~/Library/Logs/com.openai.codex/YYYY/MM/DD. Codex session transcripts normally live in $CODEX_HOME/sessions, archived transcripts in $CODEX_HOME/archived_sessions, and CLI logs in $CODEX_HOME/log. Discover other locations from the running installation rather than assuming a private layout.

Classify Candidates

Classify each item and explain the evidence:

• Task archival: old, unpinned, inactive tasks with no running work. Treat an age threshold such as 7–10 days as a user preference, not a universal rule.
• Large active task: an unusually large transcript that may benefit from a handoff and a fresh task. Size alone does not make it safe to archive.
• Scheduled-run worktree: an old unpinned run whose task can be archived through the app. Frequent scheduled tasks can intentionally create many worktrees.
• Repository worktree: clean, unused, and associated with completed work. Confirm its branch and repository ownership before proposing removal.
• Rotatable log: an old or oversized log that is not currently being written.
• Dead configuration path: a configured project path that does not exist. Distinguish temporarily unavailable volumes from genuinely obsolete paths.
• Path alias: two spellings that resolve to the same location. On Windows, compare regular and extended-length paths canonically, but do not rewrite app state merely to normalize display text.

Exclude pinned tasks, running or otherwise active work, dirty worktrees, current logs, and uncertain paths from cleanup. When the host cannot expose one of those states, classify the target as uncertain rather than inferring that it is safe.

Verify and Report

Repeat the inventory and compare it with the baseline. Verify, as applicable:

• configuration still parses
• databases open read-only and pass a non-mutating integrity check
• intended tasks or scheduled runs are archived and pinned tasks are unchanged
• active-session bytes fell only by the intended archival amount
• archived-session bytes and counts changed consistently
• worktrees still registered with Git exist, and no dirty worktree was removed
• live log directories exist and fresh logs can be created after relaunch
• path-alias and dead-path findings are resolved without unrelated config edits

Ask the user to relaunch the desktop app and confirm the sidebar, active tasks, scheduled tasks, and normal startup. Report measured disk-space changes separately from perceived performance; never repeat an anecdotal “10x faster” claim as an expected result.

The final report must include the mode, baseline, candidate set, excluded items, exact changes, validation results, and remaining risks. In Apply mode, also include the backup location, restore instructions, and the user-selected backup retention or review decision; do not delete the backup implicitly.
