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.

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 | $0.00016 | $0.00269 |
| Opus 5 | $0.00008 | $0.00134 |
| Sonnet 5 | $0.00003 | $0.00054 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
newrule 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 2d 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
Add a rule to $ARGUMENTS.
Follow the sequence, and do not skip step 2:
- Write the failing fixture first — the artifact that should trigger it.
- Write the fixture that must NOT trigger it. A plausible, well-written artifact that a careless pattern would catch. If you cannot think of one, the rule is probably too broad to add.
- Implement the rule in
src/sounding/rules/. It needs:- a
reference— the spec section or documented practice. Not optional. - a
fixstring, or aquestionwith options when intent is required - a severity: 15 / 7 / 3. When unsure, pick lower.
- a
- Two tests: fires on the bad case, silent on the good case.
- Run
/check. - Report the rule code, both fixtures, and what severity you chose and why.
Reminder: false positives are how a linter loses its audience. A rule that fires on careful work is worse than no rule.
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.

newrule is a command published in the GitHub repository alinotfoundbtw/sounding (4 stars, last pushed 7d ago), licensed MIT. It adds 16 tokens to every session and 269 once invoked, about $0.0001 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 2026-08-31.
