Enumerates chemical libraries through reaction SMARTS transformations using RDKit.

  • Creating combinatorial libraries
  • SKILL.md covers Version Compatibility, Reaction SMARTS Basics, Common Reaction SMARTS and Combinatorial Library…, plus 4 more sections
  • Runs Python scripts from its folder; calls pip
  • Enumerating products from synthetic routes

What it does

Bio Reaction Enumeration is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Enumerates chemical libraries through reaction SMARTS transformations using RDKit. Generates virtual compound libraries from building blocks using defined chemical reactions with product validation. Use when creating combinatorial libraries or enumerating products from synthetic routes.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `examples/enumerate_reactions.py` and `usage-guide.md`).

It sits in Research & Science, covering Drug discovery and cheminformatics. It works with RDKit. The repository describes itself as: The largest open-source medical AI skills library for OpenClaw🦞.

When your agent uses it

  • Creating combinatorial libraries
  • Enumerating products from synthetic routes

Example prompts

  • “Use the bio-reaction-enumeration skill to enumerate chemical libraries through reaction SMARTS transformations using RDKit”
  • “/bio-reaction-enumeration”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit b1f9b6e. 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

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    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

Bio Reaction Enumeration loads about 1.9k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 232 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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 232 words (~1,933 tokens).
