## What it does and how to use it

A **skill** that teaches Claude Code to do scientific tasks well. It is packaged knowledge the model uses whenever it is relevant.

1. Install the skill (command above).
2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
3. No commands to memorize: you talk in plain language and the skill does the rest.

## Install (Claude Code)

```bash
mkdir -p .claude/skills/blast && curl -fsSL https://doutorai.pt/data/lib/skills__blast.md -o .claude/skills/blast/SKILL.md
```

Paste this command into the terminal, in your project folder, and the component installs automatically.

# BLAST Operations with Bio.Blast

## Overview

Bio.Blast provides tools for running BLAST searches (both locally and via NCBI web services) and parsing BLAST results in various formats. The module handles the complexity of submitting queries and parsing outputs.

## Running BLAST via NCBI Web Services

### Bio.Blast.NCBIWWW

The `qblast()` function submits sequences to NCBI's online BLAST service:

```python
from Bio.Blast import NCBIWWW
from Bio import SeqIO

# Read sequence from file
record = SeqIO.read("sequence.fasta", "fasta")

# Run BLAST search
result_handle = NCBIWWW.qblast(
    progr
