Getting it into your agent

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 | $0.00009 | $0.00215 |
| Opus 5 | $0.00005 | $0.00108 |
| Sonnet 5 | $0.00002 | $0.00043 |
| Haiku 4.5 | $0.00001 | $0.00021 |
Grade C, and why
news-stop scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- "To delete all data and config: `rm -rf <data-dir>/`" What it actually says
You are helping the user clean up herald data.
Steps
- Find data directory and check status:
(Defaults tocd "${CLAUDE_PLUGIN_ROOT}" && PYTHONPATH=. python3 -c "from herald.cli import _default_data_dir; print(_default_data_dir())"~/.local/share/herald/; use--data-dirorHERALD_DATA_DIRto override.)
cd "${CLAUDE_PLUGIN_ROOT}" && PYTHONPATH=. python3 -m herald.cli status 2>/dev/null
-
Show cleanup options (use the data directory path from step 1):
- "To delete all data and config:
rm -rf <data-dir>/" - "To re-initialize: run
/news-init"
- "To delete all data and config:
-
Do NOT delete data automatically. The user decides.
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.

news-stop is a command published in the GitHub repository heurema/herald (4 stars, last pushed 5mo ago), licensed MIT. It adds 9 tokens to every session and 215 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
