watch

watch is a command for coding agents from ivbeg/newsworker. It costs 5 tokens per session (412 once invoked), scanned A, original, MIT.

A newsworker command that repeatedly checks a webpage and remembers which items it has already seen. It emits or sends only newly found items, storing tracking data in SQLite, a small file-based database.

In plain words
What is it for?
Use it to monitor news pages on a schedule, follow pagination, and deliver new items to a chosen destination.
Why use it?
It prevents repeated notifications when monitoring a page for updates. New items can be sent to the terminal, a webhook, email, or Telegram.

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.

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

watch 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

watch

Polls a page on an interval, tracks which items it has already seen (in a SQLite store under the cache dir), and emits or delivers only new items.

newsworker watch URL [OPTIONS]
Option Alias Default Description
--interval -i 300 Seconds between polls.
--channel stdout Repeatable destination: stdout, webhook, smtp, telegram.
--webhook POST new items as JSON to this URL (with retry/backoff).
--smtp-recipient SMTP recipient when --channel smtp.
--telegram-chat-id Telegram chat id when --channel telegram.
--format -f json Output format when using stdout.
--max-pages 1 Pages to follow per poll (pagination).
--max-iterations 0 Stop after N polls (0 = run until interrupted).
--config -c (default) Path to settings YAML.
--verbose -v false Verbose logging.
newsworker watch "https://example.com/news" --interval 300
newsworker watch "https://example.com/news" --channel webhook \
  --webhook https://hooks.example/new --max-pages 3

The loop shuts down cleanly on Ctrl-C / SIGTERM. Use --max-iterations N to stop after N polls (handy for cron-style single runs).

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.
