What it does
Bio Filter Sequences is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Filter and select sequences by criteria (length, ID, GC content, patterns) using Biopython. Use when subsetting sequences, removing unwanted records, or selecting by specific criteria.
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/filter_seqs.py` and `usage-guide.md`).
It sits in Research & Science, covering Bioinformatics. It works with Biopython. The repository describes itself as: The largest open-source medical AI skills library for OpenClaw🦞.
When your agent uses it
- Subsetting sequences
- Removing unwanted records
- Selecting by specific criteria
Example prompts
- “/bio-filter-sequences”
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 Filter Sequences loads about 1.9k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 354 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 354 words (~1,903 tokens).
