What it does
Sibyl Comparativist is an agent skill from Sibyl-Research-Team/AutoResearch-SibylSystem. Sibyl 比较分析者 agent - 对标 SOTA 和同类工作，定位结果贡献
Its SKILL.md is about 180 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. 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-comparativist”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, WebSearch, WebFetch, mcp__arxiv-mcp-server__search_papers, mcp__google-scholar__search_google_scholar_key_words, 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:
ReadWriteGlobGrepWebSearchWebFetchmcp__arxiv-mcp-server__search_papersmcp__google-scholar__search_google_scholar_key_wordsSkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
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 Comparativist loads about 183 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 27 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 passed
The automated check found no risky patterns in SKILL.md.
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 27 words (~183 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('comparativist', workspace_path=ws))"”
