Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00093 | $0.00613 |
| Opus 5 | $0.00046 | $0.00307 |
| Sonnet 5 | $0.00019 | $0.00123 |
| Haiku 4.5 | $0.00009 | $0.00061 |
Grade A, and why
ghostex-move-codex-session 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ghostex-move-codex-session
Explain the supported Codex CLI workflow in simple numbered steps.
Steps
-
Ask the user to run this inside the current Codex session:
/status -
Tell the user to copy the session id shown by
/status. -
Tell the user to open a shell and fork that session in the target folder:
codex fork --yolo -C ~/dev/hackathon <SESSION_ID>
Replace ~/dev/hackathon with the requested folder when the user gave a different target.
Tell the user that --yolo is the Codex alias for bypassing approvals and sandboxing. If they do not want full access, remove --yolo.
Fallback
If the user does not want to copy the id, suggest the recent-session fallback:
codex fork --all --last --yolo -C ~/dev/hackathon
Explain that --all matters because Codex normally filters fork candidates by the current working directory.
Rules
- Keep the answer short and procedural.
- Prefer
codex fork --yolo -C <folder-path> <SESSION_ID>as the primary command. - Mention that this creates a separate forked Codex session under the new working root.
- Mention that users can remove
--yoloif they do not want full-access mode. - Do not claim the active running TUI can be moved in place unless current Codex docs expose a real command for that.
- If the user asks for the exact command only, give only the command and one sentence.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ghostex-move-codex-session is a skill published in the GitHub repository maddada/Ghostex (714 stars, last pushed 4d ago), licensed MIT. It adds 93 tokens to every session and 613 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
