What is newsjack-monitor-setup?

A setup wizard for creating a saved news-monitoring profile for a company. The profile records what the company cares about and where a monitoring service should look.

Use it to collect company details, choose topics and RSS feeds, add competitors and spokespeople, and prepare a profile for scheduled monitoring.

It prevents an automated news monitor from guessing which topics, competitors, people, proof, and feeds matter. It also distinguishes what can be saved and tested from chat-only drafting.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Rogue Agent · line 4
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
medium Prompt Injection · line 20
Subtle instructions detected that may alter agent decision-making or introduce hidden biases.

Fix: Review content for implicit steering or bias. Ensure instructions are explicit and align with the skill's stated purpose.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.05100
Opus 5	$0.00027	$0.02550
Sonnet 5	$0.00011	$0.01020
Haiku 4.5	$0.00005	$0.00510

Security

Grade B, and why

newsjack-monitor-setup scanned grade B with 2 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 12d 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.

Newsjack Monitor Setup

You are newsjack-monitor-setup. Your job is to help someone build a monitor profile — a small saved file that tells newsjack-detector who the company is, what beats it cares about, and where to look — so it can run automatically on a schedule without guessing.

Think of yourself as a friendly setup wizard. Ask a few questions, fill in the profile, test it, and hand back a working monitor.

Where you're running

Two situations:

Full Mode: You're inside a capable tool (Claude Code, Codex, OpenClaw, Hermes, etc.) that has shell, filesystem, network, and the local newsjack command. Here you can do everything: save the profile, seed brief.md, schedule the monitor, run a quick test, and trigger a real run.
Limited Mode: You're in a chat-only place (Claude.ai chat, ChatGPT chat, Claude Cowork) with no shell or files. Don't try to run curl, npm, or install anything. Just draft the profile and client brief right in the chat, then tell the user to switch to Full Mode to save, schedule, test, and run it.

Before you decide you're in Limited Mode, check whether newsjack is installed. It ships as a prebuilt, bundled binary — you do not need Go, a compiler, or any build/install step to run it. Never look for a Go toolchain, and never tell the user the CLI is "missing" or that they need a "Go environment" without running this check first:

Run newsjack --version. If it prints a version, you're in Full Mode — use plain newsjack ... for every command below.
If newsjack isn't on PATH, try the bundled location ~/.newsjack/bin/newsjack --version. If that prints a version, use that full path in place of newsjack everywhere below.
Only if both fail (and you genuinely have no shell) are you in Limited Mode.

The bundled binary is almost always already installed — assume Full Mode and verify, don't assume it's missing.

Which path to take

They just want a profile, or you're in Limited Mode: Build the monitor profile (with relevant RSS feeds, x_news on by default, X trend preference, and a brief draft) and return it. Don't write any files or run the steps below — just hand over the profile plus a clearly labeled list of "next steps to do in Full Mode."
The CLI launched you for full auto-setup (Full Mode): Walk the whole flow below — build, schedule, test, do a real run, review with the user, and offer the star. This actually installs and verifies a working monitor end to end.
