Gi Splice

✂️ gi-splice

You are gi-splice, a ClawBio agent that calls the Genomic Intelligence splice-site model. Given a gene-body sequence, it returns called donor/acceptor sites and per-position probabilities via the hosted API.

> ⚠️ Remote inference — opt-in required. Unlike most ClawBio skills, this skill uploads your FASTA sequence to the hosted Genomic Intelligence API at https://api.genomicintelligence.ai. Prefer a browser? The same models run interactively at . Do not submit identifiable patient data without an appropriate data-use agreement. Key setup: see [Authentication](#authentication) below.

Trigger

Fire this skill when the user says any of:

• "predict splice sites in this gene"
• "find splice donors/acceptors"
• "score this for cryptic splice sites"
• "splice site prediction"
• "gi-splice", "G0 splice"
• "where does this transcript splice?"

Do NOT fire when:

• The user asks for full transcript structure (multi-exon annotation) → gi-annotation
• The user asks about variant effect on splicing → use variant-annotation (VEP) or chain gi-splice ref/alt comparisons

Why This Exists

• Without it: SpliceAI / similar require local GPU + weights + careful preprocessing.
• With it: One CLI call → ranked site list with positions and probabilities, in ~1 s.
• Why ClawBio: Hosted G0 BigBird inference plus ClawBio's reproducibility bundle and chaining (gi-splice → gi-annotation → variant interpretation).

API Backed

POST https://api.genomicintelligence.ai/v1/tasks/splice/predict — default model g0-splice-bigbird (G0 BigBird transformer; long-context handling for full gene bodies).

Workflow

1. Parse: single-record FASTA via clawbio.gi.gi_client.read_fasta.
2. POST the full gene body to /v1/tasks/splice/predict.
3. Render: report.md + result.json + reproducibility/.

CLI Reference

# Demo — bundled HBB gene body
python skills/gi-splice/gi_splice.py --demo --output /tmp/gi-splice-demo

# Your own FASTA
python skills/gi-splice/gi_splice.py --input my_gene.fa --output report_dir

# Via ClawBio runner
python clawbio.py run gi-splice --demo

Demo

python clawbio.py run gi-splice --demo

Bundled fixture is HBB (β-globin) gene body, reverse-complemented to gene-sense. HBB has 3 exons / 2 introns; on the coding strand the model calls ~8 sites (≈4 donor + 4 acceptor, including lower-confidence alternates).

Authentication

The skill requires a Genomic Intelligence partner key in GI_API_KEY. Resolution order:

1. --api-key CLI flag (explicit override).
2. GI_API_KEY environment variable.
3. Otherwise: the skill raises a RuntimeError pointing here.

Quick start — ClawBio hackathon key

A shared hackathon-tier key ships in .env.example at the repo root (50 concurrent / 120 rpm, opt-in only). From wherever the ClawBio files live on your machine:

# Repo root (git clone) — or ~/.claude/plugins/cache/clawbio/clawbio// for plugin installs
cp .env.example .env
set -a && source .env && set +a

Production / heavier use

Request an individual key at contact@genomicintelligence.ai, then:

export GI_API_KEY=gi_yourkeyhere

Gotchas

• Submit gene-sense, not genomic-sense. Minus-strand genes need RC'd input. The bundled HBB fixture demonstrates this — its FASTA header notes strand:-1 (gene-sense for the minus-strand HBB gene).
• Full gene body, not just an exon. The model uses long context to disambiguate; truncated input degrades accuracy.
• Donor/acceptor pairs. The model emits independent site calls. Pair them downstream by ordering + strand consistency if you need intron boundaries.
• Hackathon key is shared — GI_API_KEY for serious work.

Integration with Bio Orchestrator

Routes here on: "splice site", "splice donor", "splice acceptor", "predict splicing".

Chains with: variant-annotation (intersect calls with VEP splice consequences), gi-annotation (cross-check against predicted exon boundaries).

Safety

Research tool. Not a clinical assay.
