What it does

Sequence is an agent skill from exon-research/genomi. Deterministic sequence utilities for translation, ORFs, restriction sites, Kozak context, primer checks, and local FASTA record matching.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Translation. The repository describes itself as: Local-first, open-source Claude Science alternative, before Claude Science is a thing. Turn your AI agent into personal DNA expert. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Translation

Example prompts

  • “/sequence”

What it can do on your machine

Read from SKILL.md and the folder at commit 1df4f5b. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Sequence loads about 1.4k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 658 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

Sequence

Use this skill when the user supplies a DNA sequence and asks for ORFs, translation, restriction sites, Kozak context, primer checks, local FASTA record matching, or simple bench-style sequence QA.

Contract

  • These tools operate only on supplied sequence strings and explicitly supplied local reference FASTA files.
  • They do not use active genome context or external services.
  • Report deterministic sequence facts directly. Add biological interpretation only when the user supplies enough context or separate source evidence.

Tool Flow

  • Use sequence.analyze when more than one deterministic sequence fact may be needed.
  • Use sequence.match_reference when a local FASTA can identify the supplied sequence before downstream reasoning.
  • Use sequence.translate for frame/strand translation.
  • Use sequence.find_orfs for ATG-to-stop ORF discovery.
  • Use sequence.find_restriction_sites for common enzymes or custom motifs.
  • Use sequence.classify_kozak for ATG start-context checks.
  • Use sequence.check_primers for basic GC, Wallace Tm, self-complementarity, and optional template amplicons.

Examples:

  • sequence.translate with {"sequence":"ATGGCCATTGTAATGGGCCGCTGA","frame":1}
  • sequence.find_orfs with {"sequence":"AAATGAAATAG","min_aa":1}
  • sequence.find_restriction_sites with {"sequence":"GAATTCGGATCC","enzymes":["EcoRI","BamHI"]}
  • sequence.match_reference with {"sequence":"ATGAAATAA","reference_fasta":"refs.fa"}

Answering

Give the computed result and enough coordinates or frame details to make the answer auditable. Do not turn sequence utility output into medical or personal-genome interpretation.

Cross-Capability Synthesis

A scope-limited result from this capability is not a final user-facing answer when other Genomi capabilities can contribute orthogonal evidence to the same question. Returning "cannot answer" while applicable capabilities remain unexamined is a host-agent failure mode.

Tools

sequence.analyze

Run a compact deterministic sequence analysis bundle and point to focused sequence tools when needed.

Use when: The user supplies DNA/RNA sequence text and may need translation, ORF, motif, Kozak, or local FASTA identity facts.

Why necessary: Supplied DNA strings need deterministic sequence utilities before any biological interpretation.

Example prompts: Translate this DNA sequence and find ORFs.

Result semantics: Computes deterministic sequence facts from supplied text and optional local FASTA reference matches; no external annotation is performed.

sequence.check_primers

Check basic primer properties and optional template amplicons.

Use when: Checks primer GC, melting temperature, self-complementarity, and optional amplicon context.

Why necessary: Primer checks combine basic thermodynamic and amplicon facts that are not variant evidence.

Result semantics: Performs lightweight deterministic primer checks; it does not replace full primer-design thermodynamics.

sequence.classify_kozak

Classify Kozak sequence context around ATG start codons.

Use when: Checks Kozak/start-codon context around a supplied DNA sequence position.

Why necessary: Start-codon context is a specialized expression-design check and should stay separate from general translation.

Result semantics: Uses the simple -3 A/G and +4 G Kozak rule; experimental expression strength needs separate evidence.

sequence.find_orfs

Find ATG-to-stop open reading frames in a supplied DNA sequence.

Use when: Finds open reading frames and coding-sequence candidates in a supplied DNA sequence.

Why necessary: ORF detection identifies candidate coding regions without relying on external annotation.

Result semantics: Finds simple ATG-to-stop ORFs from supplied sequence text; biological annotation requires separate source evidence.

sequence.find_restriction_sites

Find common restriction enzyme or custom motif sites in a supplied DNA sequence.

Use when: Maps restriction enzyme sites and sequence motifs in a supplied DNA sequence.

Why necessary: Cloning and motif checks need exact site positions in the supplied sequence.

Result semantics: Reports motif positions in the supplied sequence; it does not model methylation or digestion conditions.

sequence.match_reference

Match a supplied DNA sequence against local FASTA records and return record identifiers plus annotations.

Use when: The task supplies a DNA sequence and a local FASTA/reference set that can identify the sequence record before downstream reasoning.

Why necessary: Local FASTA matching identifies sequence records before downstream reasoning about that sequence.

Result semantics: Returns exact local FASTA record matches and header annotations; the host agent decides whether a matched record answers the question.

sequence.translate

Translate a DNA sequence in a selected frame and strand using the standard genetic code.

Use when: Translates a supplied DNA sequence into codons or amino acids for the requested frame and strand.

Why necessary: Protein translation requires explicit frame and strand control rather than informal sequence reading.

Result semantics: Computes deterministic sequence facts from the supplied string only; no genome context or external IO is used.

Can I use Sequence in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add exon-research/genomi --skill sequence -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sequence, .gemini/skills/sequence, .github/skills/sequence and .opencode/skills/sequence in your project.

What does Sequence need to run?

SKILL.md names no scripts, command-line tools or credentials: Sequence is instructions for the agent only.
