Feedsmith

Use this skill for Feedsmith v3+ (feedsmith): parse and generate RSS, Atom, RDF, JSON Feed, and OPML with structure-preserving, typed APIs. Docs: feedsmith.dev. Snapshot 3.0.1 (2026-10-01).

Workflow

1. Inspect the local surface:
   • Installed feedsmith version (bun pm ls feedsmith / bun info feedsmith). This skill targets 3.x; latest is 3.0.1 (ESM build now ships .mjs files; no API changes from 3.0.0).
   • Parse vs generate vs OPML vs detect-only usage.
   • Dates: raw strings vs parseDateFn / Date on generate.
   • v2 leftovers: feedsmith/types, { lenient: true }, flat Atom strings, string RSS persons, singular dc.* fields, Rss/Atom/Json/Rdf type namespaces.
2. Prefer dedicated parsers when format is known; use parseFeed only for unknown/mixed sources.
3. Refresh docs when tags drift. Start from source-map.md.
4. Route deeper detail:
   • Parse/detect/dates/errors: parsing.md
   • Generate, strict mode, stylesheets, OPML extras: generating.md
   • Formats, namespaces, types: formats-namespaces.md
   • v2→v3 breaking changes: migration-v2-to-v3.md
5. Prefer bun / bunx in command examples.
