Turn an article URL into a clean, vault-ready markdown note with the defuddle CLI, stripping ads, navigation and comments and cutting 40-60% of tokens versus a raw fetch. Prefer it over a raw web fetch whenever the task is reading or ingesting a normal web article. Triggers: "/defuddle <url>", "clean import this page".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /defuddle — clean web→markdown
The `defuddle` CLI (by kepano, MIT, v0.19.1) is installed globally via npm. Node is the only dependency.
## Commands
```bash
# article → clean markdown on stdout
defuddle parse <url> --markdown
# with frontmatter (title/author/published/domain) — for the vault
defuddle parse <url> --markdown --frontmatter
# straight to a file
defuddle parse <url> --markdown --frontmatter --output "<path>.md"
```
## The "article into the vault" flow
1. `defuddle parse <url> --markdown --frontmatter` → draft.
2. Then the standard ingest: a vault note (provenance `origin: external`!), reindex, ≥1 inbound link (rules `always-archive-artifacts-to-vault`, `no-orphan-notes-rule`).
## ⚠️ Gotchas (verified by a live /tt run, 2026-07-04)
- **exit code = 0 even on failure** ("Error: fetch failed" is printed, but the code says success). In scripts, check stdout for `^Error:`, NOT the exit code.
- Empty input → a cryptic destructure error (also exit 0).
- The CLI is machine-local: on another machine run `npm install -g defuddle` first (node required). The skill syncs across the cluster; the binary does not.

How to install
mdr add tonydzi/second-brain-starter-kit/defuddle@sha256:9eea931262dd7cc4The line at the top of this page pins the label git:20261007.cd6c208, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
