What it does
Auto Review Loop is an agent skill from AI4Scientist/nano-scientist. Autonomous multi-round research review loop. Repeatedly reviews using Gemini via gemini-review MCP, implements fixes, and re-reviews until positive assessment or max rounds reached. Use when user says "auto review loop", "review until it passes", or wants autonomous iterative improvement.
Its SKILL.md is about 2.8k 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 Model Context Protocol and Google Gemini. The repository describes itself as: An autonomous research agent that turns a topic into a peer-reviewed technical report.
When your agent uses it
- User says auto review loop
- Review until it passes
- Wants autonomous iterative improvement
Example prompts
- “auto review loop”
- “review until it passes”
- “/auto-review-loop”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Check for review-stage/REVIEW_STATE.json *(fall back to ./REVIEW_STATE.json if not found — legacy path)*
- Read project narrative documents, memory files, and any prior review documents
- Read recent experiment results (check output directories, logs)
- Identify current weaknesses and open TODOs from prior reviews
- Initialize round counter = 1 (unless recovered from state file)
- Create/update review-stage/AUTO_REVIEW.md with header and timestamp
What it can do on your machine
Read from SKILL.md and the folder at commit 7132192. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json and markdown).
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
Auto Review Loop loads about 2.8k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 1,099 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: warnings
The automated check found patterns that need a careful read before installing.
- WarningTells the agent its actions are pre-authorized / not to stop for confirmationSKILL.md:223
t << 'EOF' > file`) to write in chunks. Do NOT ask the user for permission — just do it silently.
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 1,099 words (~2,797 tokens).
“Autonomously iterate: review → implement fixes → re-review, until the external reviewer gives a positive assessment or MAX_ROUNDS is reached.”
