Building practical tools and applied ML projects: agent workflow budgets, repo-local context files, audio inference, and reproducible public claims.

tool-tax: measure hidden token cost in live MCP servers, OpenAPI files, and agent tool catalogs; diff PR changes, generate a slim progressive-loading index, and run a lazy-schema MCP stdio proxy. Install:pipx install tool-tax.site2voice: use public web patterns asSITE.mdandVOICE.mdcontext files so agents get page structure and copy rhythm without inheriting source-site subject matter. Install:pipx install site2voice.Modulation-aware-key-estimator: estimate region-wise musical keys in songs with modulation, expose the model through a CLI and FastAPI service, and optionally transpose detected regions to one target key.
- MCP/tool-schema context bloat
- AI-agent context files for web structure and copy
- applied audio ML and music-information retrieval
- CI checks and reproducible benchmarks
- concise public docs with clear boundaries
