bio-seq-objects
Create and manipulate Seq, MutableSeq, and SeqRecord objects using Biopython. Use when creating sequences from strings, modifying sequence data in-place, or building annotated sequence records.
npx skills add BioTender-max/awesome-bio-agent-skills --skill seq-objects --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
## Version Compatibility Reference examples tested with: BioPython 1.83+ Before using code patterns, verify installed versions match. If versions differ: - Python: `pip show <package>` then `help(module.function)` to check signatures If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying. # Seq Objects Create and manipulate biological sequence objects using Biopython. **"Create a sequence object"** → Wrap a raw string in a typed sequence container for biological operations. - Immutable: `Seq('ATGC')` (BioPython) — string-like, supports complement/translate - Mutable: `MutableSeq('ATGC')` (BioPython) — supports in-place edits - Annotated: `SeqRecord(Seq(...), id=...)` (BioPython) — adds metadata for file I/O ## Required Imports ```python from Bio.Seq import Seq, MutableSeq from Bio.SeqRecord import SeqRecord ``` ## Core Objects ### Seq - Immutable Sequence The basic sequence object. Immutable like Python strings. ```python seq = Seq('ATGCGATCGATCG') ``` Seq objects support string-like operations: ```python len(seq) # Length seq[0] # First base seq[-1] # Last base seq[0:10] # Slice

What does the bio-seq-objects skill do?
Create and manipulate Seq, MutableSeq, and SeqRecord objects using Biopython. Use when creating sequences from strings, modifying sequence data in-place, or building annotated sequence records.
How do I install it?
Run `npx skills add BioTender-max/awesome-bio-agent-skills --skill seq-objects --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From BioTender-max/awesome-bio-agent-skills, a repository with 135 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
