scan

A newsworker command that looks for existing RSS, Atom, or JSON Feed links on a webpage. RSS, Atom, and JSON Feed are standard formats for publishing lists of updates that other tools can read.

In plain words
What is it for?
Use it to discover and export feeds from news pages, optionally including feeds found through a sitemap.
Why use it?
It finds published feeds without requiring manual inspection of page source. It can verify discovered feeds and include available metadata such as type, entry count, and language.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 5 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 335 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

scan

Scans a page for already-published RSS/Atom/JSON Feed declarations (via autodiscovery links, feed icons, link heuristics, WebSub, and optional sitemaps) and reports them.

newsworker scan URL [OPTIONS]
Option Alias Default Description
--format -f json Output format: json, rss, atom, csv, opml.
--sitemap false Also discover feed URLs from the site's /sitemap.xml.
--no-verify false Skip fetching and parsing candidate feeds.
--output -o (stdout) Write the result to a file.
--verbose -v false Verbose logging.
newsworker scan "https://www.dta.gov.au/news/"
newsworker scan "https://www.dta.gov.au/news/" -f opml -o feeds.opml
newsworker scan "https://example.com" --sitemap --format json

scan verifies every candidate feed by parsing it unless --no-verify is set. feedtype, num_entries, and language metadata are included where available.

See discovery and output formats.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scan is a command published in the GitHub repository ivbeg/newsworker (87 stars, last pushed 13d ago), licensed MIT. It adds 5 tokens to every session and 335 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
