Type	Claude Skill
Supplier	jaechang-hits (community OSS, CC BY 4.0)
Availability	GA — part of the BixBench-evaluated SciAgent-Skills collection
Pricing	Free / OSS — license not stated upstream
Capabilities	Read/Write — Claude runs the skill’s Python locally (Bash), not as an MCP tool

How to install

SciAgent-Skills is not an npm package — skills are plain markdown read directly by the agent (no npx/npm).

• Claude Code — clone and load as a plugin:

  git clone https://github.com/jaechang-hits/SciAgent-Skills
  

  Then inside Claude Code run /plugin install sciagent-skills (verify it appears under /plugin → Installed). Clone into your project directory so Claude Code picks the skills up via CLAUDE.md.

• Manual / other agents — point the agent at the skill file directly:

  cp -r SciAgent-Skills/skills/genomics-bioinformatics/databases/ena-database ~/.claude/skills/
  

  The skill declares its own Python dependencies in its SKILL.md; install them when prompted on first use.

What it does

ENA REST API for sequences, reads, assemblies, and annotations. Portal API search, Browser API retrieval (XML/FASTA/EMBL), file reports for FASTQ/BAM URLs, taxonomy, cross-refs. For multi-DB Python use bioservices; for NCBI-only use pubmed-database or Biopython Entrez.

Primary use cases: ENA REST API for sequences, reads, assemblies, and annotations.

Notes

Distributed as a SKILL.md (plus code examples) in the SciAgent-Skills collection — Claude executes it locally via Bash/Python rather than as an MCP server. Upstream license: not stated upstream. The skill directory upstream is skills/genomics-bioinformatics/databases/ena-database.
