sessions

sessions is a command for Claude Code, Codex from mturac/everything-openai-codex. It costs 14 tokens per session (4,466 once invoked), scanned A, original, MIT.

A command for listing, loading, renaming, and inspecting saved Codex sessions and their metadata. It works with the current session folder and can still read older session files.

In plain words
What is it for?
Use it to browse session history, load a session, create or edit an alias, and inspect session details.
Why use it?
It helps you find previous work without searching through session files manually, while keeping project source files unchanged.

Command for Claude CodeCodex

Written for Claude Code and Codex: $ARGUMENTS substitution, but also reads ~/.codex or $CODEX_HOME. Also seen: mentions Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sessions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Sessions Command

Manage OpenAI Codex session history - list, load, alias, and edit sessions stored in ~/.codex/session-data/ with legacy reads from ~/.codex/sessions/.

Execution Contract

  • Role: session-history operator for local OpenAI Codex metadata only.
  • Surface: read or update session aliases and session metadata; do not modify project source files.
  • State: treat ~/.codex/session-data/, ~/.codex/sessions/, and aliases as durable local state; summarize old history instead of replaying it.
  • Compatibility: keep legacy ~/.codex/sessions/ reads while preferring ~/.codex/session-data/.
  • Rollback: alias edits must be reversible by removing the alias entry; never delete session files.
  • Validation and errors: validate requested IDs or aliases, report missing sessions without guessing, and leave files unchanged on errors.
  • Verification command: node tests/lib/session-manager.test.js && node tests/scripts/session-inspect.test.js.

Usage

/sessions [list|load|alias|info|help] [options]

Actions

List Sessions

Display all sessions with metadata, filtering, and pagination.

Use /sessions info when you need operator-surface context for a swarm: branch, worktree path, and session recency.

/sessions                              # List all sessions (default)
/sessions list                         # Same as above
/sessions list --limit 10              # Show 10 sessions
/sessions list --date 2026-02-01       # Filter by date
/sessions list --search abc            # Search by session ID

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
