Calculates molecular descriptors and fingerprints using RDKit.

  • Featurizing molecules for machine learning

  • Runs Python scripts from its folder; calls pip
  • Filtering by drug-likeness criteria

What it does

Bio Molecular Descriptors is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Calculates molecular descriptors and fingerprints using RDKit. Computes Morgan fingerprints (ECFP), MACCS keys, Lipinski properties, QED drug-likeness, TPSA, and 3D conformer descriptors. Use when featurizing molecules for machine learning or filtering by drug-likeness criteria.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `examples/calculate_descriptors.py` and `usage-guide.md`).

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

When your agent uses it

  • Featurizing molecules for machine learning
  • Filtering by drug-likeness criteria

Example prompts

  • “Use the bio-molecular-descriptors skill to calculate molecular descriptors and fingerprints using RDKit”
  • “/bio-molecular-descriptors”

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 Molecular Descriptors loads about 1.6k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 264 words (~1,586 tokens).

“Reference examples tested with: RDKit 2024.03+, numpy 1.26+, pandas 2.2+”
