§ Product · Codaris

Deterministic pipeline engineering for Nextflow.

Codaris is a development environment for Nextflow DSL2 and nf-core pipelines. You describe the analysis; deterministic code scaffolds the project, resolves modules and containers, wires channels, lints against nf-core rules and runs a local test profile. The language model handles only small, validator-gated tasks, so hallucinated container tags and broken channel wiring are caught before anything reaches your cluster.

§ 1 / What it does

Capabilities.

  1. 01

    Deterministic build

    A fixed sequence (extract, scaffold, install modules, stitch, lint, test, report) owns module names, include paths and configuration; the model drafts only subworkflow bodies, and each draft must pass validation.

  2. 02

    nf-core scaffolding

    Projects are created with the nf-core tooling and ship with a generated test profile, pinned container config and a fixture samplesheet, so a test run works from the first commit.

  3. 03

    Container resolution

    A local registry of container recipes and pinned composite images resolves single and piped multi-tool processes into a container config automatically.

  4. 04

    Lint and autofix

    An AST-based compliance suite plus native nf-core lint feed a fix loop that iterates until clean, with backups for rollback.

  5. 05

    Migration and conversion

    Rewrites DSL1 pipelines to DSL2 and converts Snakemake rules and WDL tasks, each with a record of what changed.

  6. 06

    Test data on demand

    Subsampled offline fixtures, in-silico read simulators, or streamed SRA and ENA samples, so pipelines are tested without staging large datasets.

§ 2 / Questions

Often asked.

Does the model write my Nextflow code?
Mostly no. Drafts are compile-checked, nf-core linted and channel-checked before anything lands. A failing draft is never written to disk.
Which models can it use?
It is model-agnostic: hosted providers or local models through Ollama, with your own keys, so it can also run fully offline.
How is a generated pipeline tested?
Using the generated test profile and fixture samplesheet, Codaris runs a compile check, then a full local run against subsampled or streamed data, and retries with more memory on out-of-memory exits.
