Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00102 | $0.00261 |
| Opus 5 | $0.00051 | $0.00130 |
| Sonnet 5 | $0.00020 | $0.00052 |
| Haiku 4.5 | $0.00010 | $0.00026 |
Grade A, and why
nav 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 11d 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
Enable, disable, or check claudenews key navigation.
/claudenews:nav on— make news global + install the Hammerspoon key tap (ctrl+shift+←/→)/claudenews:nav off— disable and remove the wiring (per-session rotation resumes)/claudenews:nav status— show current state
Raw slash-command arguments: $ARGUMENTS
bash ${CLAUDE_PLUGIN_ROOT}/commands/nav.sh $ARGUMENTS
Report the script output verbatim. If Hammerspoon is not installed, walk the user through the printed install + Accessibility-permission steps.
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.

nav is a command published in the GitHub repository bhpark1013/claudenews (22 stars, last pushed yesterday), licensed MIT. It adds 102 tokens to every session and 261 once invoked, about $0.0005 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.
