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 5.1 | $0.00122 | $0.01791 |
| Opus 5.5 | $0.00049 | $0.00716 |
| Sonnet 5.5 | $0.00024 | $0.00358 |
| Haiku 4.5 | $0.00012 | $0.00179 |
Grade A, and why
codex-autonomous-dev 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 1mo 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NightPilot / 夜航员
Purpose
NightPilot is a lightweight operating layer around original Codex. It helps Codex run long development sessions with fewer interruptions by using durable local state, permission hardening where Codex supports it, task queues, branch/worktree isolation, retry classification, context handoffs, resource guards, and verification evidence.
NightPilot is Codex-coupled. It augments a Codex conversation, Codex CLI session, or explicit user-started Codex project context. It is not a standalone agent, daemon, scheduler, or replacement Codex runtime, and it must not initiate unrelated work outside the selected project and goal.
It does not bypass Codex internals, real account authorization, payment, CAPTCHA, missing secrets, or platform outages.
Critical hallucination guard: when the network fails, do not rewrite network configuration, edit DNS/proxy/firewall/router settings, restart or reopen the parent Codex app, reinstall Codex, create a replacement Codex, or attempt to rewrite Codex. Classify the failure, retry with bounded backoff when safe, park the affected task if needed, and continue independent local work.
Before changing this workflow, read NIGHTPILOT_REQUIREMENTS_LOCK.md. That file is the current
source of truth for product direction and acceptance criteria.
Trigger Policy
Use this skill whenever the user asks for long-running, unattended, full-auto, autonomous, goal-mode, overnight, hands-off, or old-workflow takeover development.
Common trigger phrases include:
- English:
long-running,unattended,full-auto,autonomous,goal mode,overnight,hands-off,keep running,no approval prompts,take over this project,start now. - Brand/plugin names:
NightPilot,夜航员,$codex-autonomous-dev,codex-autonomous-dev. - Chinese:
长时间开发,无人开发,目标模式,全自动,自动跑,自动开发,自动创建分支,撒手不管,睡觉也能跑,人不在也继续,不要一直申请权限,不要中断,网络波动不中断,授权不中断,接管当前项目,老对话接管,直接开始全自动开发.
When triggered, do not merely explain the workflow. Inspect the current project, initialize or reuse
.codex-autonomous/, harden supported Codex permission paths, adopt the goal, audit readiness, and
start the run loop when the user asked for execution.
What ships with it
4 files 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.

codex-autonomous-dev is a skill published in the GitHub repository Dear-Ded/nightpilot-codex (1 stars, last pushed 3mo ago), licensed MIT. It adds 122 tokens to every session and 1,791 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-08-31.
