Alignment: gxy-sketches ↔ Galaxy Workflow Foundry

Adjacent project, different target, overlapping ingest sources. This doc records the seams where the Foundry’s per-source summary Molds (summarize-paper, summarize-nextflow, summarize-cwl) and the eventual summarize-galaxy-workflow should align with gxy-sketches, so the two projects stay legible to each other without becoming dependent.

gxy-sketches is not a Foundry project. It is owned by another contributor (boss). The Foundry does not consume it at runtime, casting time, or build time. “Alignment” here means: shared field names, shared mental model for test manifests, and a documented mapping for vocabularies — nothing more invasive.

What gxy-sketches is

Repo: /Users/jxc755/projects/repositories/gxy-sketches (no public URL recorded here).

• Python project. typer CLI: gxy-sketches ingest|generate|validate|list.
• Unit: a sketch directory under sketches/<domain>/<slug>/ containing SKETCH.md (YAML frontmatter + markdown body), optional test_data/, optional expected_output/.
• Sources (v1): nf-core (Nextflow) and Galaxy IWC (gxformat2 .ga + planemo *-tests.yml). Snakemake / WDL deferred to v2.
• Pipeline: ingest clones a source repo into workflows_cache/, builds a WorkflowRecord with an attached TestManifest; generate calls Claude (prompt-cached system prompt) and writes one SKETCH.md per workflow; validate lints the corpus.
• Consumer: gxy3 (chat-driven bioinformatics desktop app) loads sketches/**/*.md the way Claude Code loads skills. The sketch teaches the agent when to pick this analysis class and the high-level recipe — it is a routing / decision aid, not a constructor.
• Sketch body shape (fixed, enforced by prompt): # Title → ## When to use this sketch → ## Do not use when → ## Analysis outline → ## Key parameters → ## Test data → ## Reference workflow.

Pydantic types worth knowing (src/gxy_sketches/schema.py):

• WorkflowRecord — ingestor output: ecosystem, slug, display_name, source_url, version, license, harvested files: list[WorkflowFile], test_manifest: TestManifest | None, tool_versions.
• TestManifest — inputs: list[TestDataRef], outputs: list[ExpectedOutputRef], output_source_map.
• TestDataRef — role, path (under test_data/), url, sha1, filetype, description. Either path or url required.
• ExpectedOutputRef — role, path (under expected_output/), url, kind, description, assertions: list[str]. Needs at least one of path/url/assertions.
• ToolSpec — name, version. Bare-string back-compat in input.
• SketchFrontmatter — strict (extra="forbid"); fields: name (kebab, 3-80), description (30-600), domain (enum), organism_class, input_data, source: SketchSource, tools: list[ToolSpec], tags, test_data, expected_output.
• SketchSource — ecosystem, workflow, url, version, license, slug.

domain enum (from prompts.py): variant-calling | assembly | rna-seq | single-cell | metagenomics | epigenomics | proteomics | phylogenetics | long-read | amplicon | structural-variants | qc | annotation | other.

Why it is adjacent, not the same target

Concrete alignment moves

Cheap, additive, none of them block either project. Each is a recommendation, not a contract.

1. Test-fixture field-name parity

The Foundry’s summary-nextflow.schema.json and summary-cwl.schema.json will need a test-fixture sub-block. Adopt TestDataRef / ExpectedOutputRef field names verbatim:

• inputs[] items: role, path, url, sha1, filetype, description.
• outputs[] items: role, path, url, kind, description, assertions[].
• path / url semantics: either / or / both, same rules as gxy-sketches.

Rationale: a Foundry summary becomes structurally consumable by anyone using gxy-sketches’ TestManifest shape and vice versa. No code dependency; just naming convergence. Cheap to do; hard to retrofit.

Drop: gxy-sketches’ constraint that path must be under test_data/ — that is a sketch-bundle invariant (the validator enforces it because the sketch directory bundles fixtures). The Foundry’s summary describes a workflow’s test fixtures as data; bundling is out of scope. Also drop the 5 MB cap thinking — it is a sketch-bundle invariant, irrelevant to summary schemas.

2. Tool-spec parity

summarize-galaxy-tool and summarize-nextflow / summarize-cwl all need to enumerate tools with versions. Match ToolSpec(name, version). Same field names.

3. Source-record parity

When the Foundry’s summarize-paper / summarize-nextflow / summarize-cwl (and a future summarize-galaxy-workflow, see §5) emit a “this is where I came from” block, mirror SketchSource field names: ecosystem, workflow, url, version, license, slug.

The Foundry’s ecosystem vocabulary should be a superset: gxy-sketches has nf-core | iwc | snakemake-workflows | wdl. The Foundry’s source axis is currently paper | nextflow | cwl; if the Foundry adds an IWC summarizer (§5), use iwc not a new term.

4. Domain ↔ iwc/* vocabulary mapping

gxy-sketches’ fixed domain enum overlaps heavily with Foundry’s iwc/* tag family (iwc/variant-calling, iwc/rna-seq, …). They will not be identical — gxy-sketches’ domain is a single value chosen by the LLM; the Foundry’s iwc/* is a multi-tag classification seeded from IWC directory layout (see INITIAL_CORPUS_INGESTION.md). Document the mapping in meta_tags.yml descriptions for iwc/* keys; do not force a merge.

5. Inventory gap surfaced by alignment: summarize-galaxy-workflow

gxy-sketches treats IWC (gxformat2 .ga files + planemo *-tests.yml) as a first-class source. The Foundry has no summarize-galaxy-workflow Mold — its source axis is paper/nextflow/cwl only. Worth adding to the inventory:

• It would serve compare-against-iwc-exemplar directly (the structural diff Mold needs a structured view of the exemplar workflow it compares against — currently unspecified).
• It would let a future sketch cast target be populated from IWC workflows entirely inside the Foundry pipeline, without re-implementing gxy-sketches’ IWC ingestor.
• It mirrors summarize-cwl cleanly (same target — Galaxy — on the input side).

Add to INITIAL_MOLDS.md as a candidate; do not commit until the first walk-through.

6. Inventory gap: decision-aid layer

The sketch body’s ## When to use / ## Do not use when sections are a routing/decision aid, not technical content. The Foundry’s summarize-* Molds are technical (DAG, containers, IO). The Foundry has no Mold today that produces “given this workflow, when should an agent reach for it?” content.

If a future sketch cast target is added (§7), it will need either:

• A new Mold (derive-routing-aid or similar) that consumes a Foundry summary and emits the decision-aid sections, or
• The decision-aid sections come from somewhere else (gxy-sketches’ own LLM prompt, the harness, …).

This is a deferred design question, not a v1 commit. Recorded here so it is not lost when the alignment is revisited.

7. Future cast target: sketch

A plausible — not committed — Foundry cast target is sketch: a summarize-nextflow / summarize-galaxy-workflow / summarize-cwl Mold cast emits a SKETCH.md-shaped artifact (frontmatter + the technical body sections). gxy-sketches today derives this content via a single LLM call against the raw workflow files; a Foundry-cast version would be derived from a structured summary instead.

Open questions if/when this is pursued:

• Does the cast emit only the technical sections (## Analysis outline, ## Key parameters, ## Test data, ## Reference workflow) and leave the routing sections to gxy-sketches’ own pipeline?
• Or does the Foundry add a routing-aid Mold (§6) and own the whole sketch?
• Either way, this is a v2+ concern. v1: align field names, do not entangle pipelines.

What is not aligned

Explicit non-goals, so future contributors do not retrofit them:

• Storage backends. gxy-sketches is Python + pydantic + typer + frontmatter lib + plain markdown. The Foundry is TypeScript + Astro + Ajv. No code sharing.
• Validators. gxy-sketches’ validator enforces a sketch-directory bundle contract (file presence, orphan files, 5 MB cap, name uniqueness). The Foundry’s validator enforces a content-collection contract (frontmatter schema, wiki-link integrity, tag coherence, Mold ref resolution). Different jobs.
• 5 MB test-fixture cap. Sketch-bundle-only invariant. Do not propagate into Foundry summary schemas.
• LLM generation pipeline. gxy-sketches: one-shot prompt-cached call per workflow, JSON output, deterministic frontmatter fill-in by the writer. Foundry: per-Mold cast with per-kind dispatch over typed references (patterns LLM-condensed, schemas verbatim, manpages → JSON sidecar). Different shapes for different jobs.
• IWC mirroring. gxy-sketches clones IWC into workflows_cache/. The Foundry does not — patterns cite IWC by URL (INITIAL_CORPUS_INGESTION.md). If summarize-galaxy-workflow lands (§5), revisit whether the Foundry needs an IWC clone for that Mold’s runtime; the answer should still be “no” if the cast skill operates on URLs supplied at runtime.

Linking moves

Done in this commit:

• This file added under vault/projects/workflow_state/skills/.
• RELEVANT_PATHS.md patched: new “Adjacent projects” section pointing at gxy-sketches.

Suggested future, not done here:

• INITIAL_MOLDS.md source-summarization tier: a one-line “see also INITIAL_GXY_SKETCHES_ALIGNMENT.md for field-name parity” pointer.
• A meta_tags.yml description on iwc/* keys noting the gxy-sketches domain mapping.
• When summarize-galaxy-workflow is added to the inventory, link this doc from its Mold note.

Open questions

• Worth a follow-up Mold note summarize-galaxy-workflow in inventory before walk-throughs, or wait until walks force it?
• Does gxy-sketches’ boss want field-name parity adopted on their side too (e.g., would they rename anything to match Foundry choices), or is parity a one-way concession from Foundry?
• Is a sketch cast target on the v2+ roadmap, or stays out of scope permanently and gxy-sketches keeps owning sketch generation end-to-end?
• gxy-sketches v2 lists Snakemake + WDL; the Foundry’s source axis would need snakemake / wdl if alignment is symmetric. Defer until those v2 ingestors land in gxy-sketches.
