What it does
Sibyl Codex Writer is an agent skill from Sibyl-Research-Team/AutoResearch-SibylSystem. Sibyl Codex 写作 agent - 使用 Codex (GPT-5) 撰写论文
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with OpenAI and Model Context Protocol. The repository describes itself as: Fully Autonomous AI Research System with Self-Evolution, built natively on Claude Code.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/sibyl-codex-writer”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, Bash, mcp__codex__codex, mcp__codex__codex-reply, Skill
What it can do on your machine
Read from SKILL.md and the folder at commit c30c216. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteGlobGrepBashmcp__codex__codexmcp__codex__codex-replySkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3codex
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sibyl Codex Writer loads about 268 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 56 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Glob, Grep, Bash, mcp__codex__codex, mcp__codex__codex-reply, Skill
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 56 words (~268 tokens).
“!SIBYL_WORKSPACE="$ARGUMENTS[0]" .venv/bin/python3 -c "from sibyl.orchestrate import render_skill_prompt; import os; ws = os.environ.get('SIBYL_WORKSPACE', ''); print(render_skill_prompt('codex_writer', workspace_path=ws))"”
