Recognise printed sheet-music photos/scans into editable MusicXML. Splits a page into one image per musical piece BEFORE OMR (so multiple songs on one page are not merged), then runs Audiveris and/or oemer. Use when the user has photos of notes/scores and wants MusicXML, MIDI, or a clean re-engraving.

A domain-agnostic methodology for building, extending, reviewing, and refactoring ontologies, domain models, taxonomies, and knowledge-graph schemas. Synthesises Stanford Ontology 101, OntoClean/UFO, Gruber's design criteria, Domain-Driven Design, OBO Foundry governance, and agent-facing platform practice into one process with explicit conflict resolution.

Audit a knowledge graph or ontology for structural health across seven axes — orthogonality, granularity, taxonomic hygiene, identity & rigidity, relationship semantics, competency questions, and inference safety — and flag defects before they corrupt inference.

Onboarding for the open-science framework: asks which components you want, checks your machine, and sets up tokens safely. Install this first.
Context management: clear the session and resume from the context files (session jumps), pane registration, and subagent checkpoints. Needs tmux and a project made with open-science-project.
Project management: the project template, tasks with a node header, the task map, context files with line caps, citations and logs.
Publishing: export the public part of a private repo through a manifest, check it, push it after your approval, build the project site, and release data on Zenodo.
