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. The same models also run interactively at https://genomicintelligence.ai. Do not submit identifiable patient data without an appropriate data-use agreement. Key setup: see 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. Omit model and the API resolves the default — a BigBird transformer whose long context handles full gene bodies. GET /v1/tasks/splice/models is the current list.

Contract note. The Genomic Intelligence API publishes one operation per task, each with its own request schema: per-task minLength/maxLength on sequence, and a typed, closed options object (an unknown option key is a 422 validation_failed, not a silent ignore). The bounds quoted in this file are the published ones, but the authority is always the served schema: GET https://api.genomicintelligence.ai/v1/openapi.json.

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 donor and acceptor sites at the annotated intron boundaries, plus lower-confidence alternates. Read the counts and scores from your own run.

Authentication

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

1. --api-key <value> 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 (opt-in only). Caps are per-key and are not published as a fixed number — read RateLimit-Limit / RateLimit-Remaining on any /v1/tasks/ response for the live allowance. The runner keeps them for you: they are in result.json under rate_limit, and a 429 names them on the error line. From wherever the ClawBio files live on your machine:

# Repo root (git clone) — or ~/.claude/plugins/cache/clawbio/clawbio/<version>/ 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:
