Feed To Md

RSS/Atom to Markdown

Use this skill when the task is to convert an RSS/Atom feed URL into Markdown.

What this skill does

• Converts a feed URL to Markdown via a bundled local script
• Supports stdout output or writing to a Markdown file
• Supports limiting article count and summary controls

Inputs

• Required: RSS/Atom URL
• Optional:
  • output path
  • max item count
  • template preset (short or full)

Usage

Run the local script:

python3 scripts/feed_to_md.py "<feed_url>"

Write to file:

python3 scripts/feed_to_md.py "https://example.com/feed.xml" --output feed.md

Limit to 10 items:

python3 scripts/feed_to_md.py "https://example.com/feed.xml" --limit 10

Use full template with summaries:

python3 scripts/feed_to_md.py "https://example.com/feed.xml" --template full

Security rules (required)

• Never interpolate raw user input into a shell string.
• Always pass arguments directly to the script as separate argv tokens.
• URL must be http or https and must not resolve to localhost/private addresses.
• Every HTTP redirect target (and final URL) is re-validated and must also resolve to public IPs.
• Output path must be workspace-relative and end in .md.
• Do not use shell redirection for output; use --output.

Safe command pattern:

cmd=(python3 scripts/feed_to_md.py "$feed_url")
[[ -n "${output_path:-}" ]] && cmd+=(--output "$output_path")
[[ -n "${limit:-}" ]] && cmd+=(--limit "$limit")
[[ "${template:-short}" = "full" ]] && cmd+=(--template full)
"${cmd[@]}"

Script options

• -o, --output <file>: write markdown to file
• --limit <number>: max number of articles
• --no-summary: exclude summaries
• --summary-max-length <number>: truncate summary length
• --template <preset>: short (default) or full
