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 5.1 | $0.00000 | $0.00159 |
| Opus 5 | $0.00000 | $0.00079 |
| Sonnet 5 | $0.00000 | $0.00032 |
| Haiku 4.5 | $0.00000 | $0.00016 |
Grade A, and why
sentence-case-headings 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 8d 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
metadata: alwaysApply: true
Sentence Case Headings
Always use sentence case for all headings in documentation, markdown files, and code comments. Only the first word and proper nouns should be capitalized; all other words must be lowercase. Do not use title case except for proper nouns.
Apply this rule to all heading levels (e.g., H1, H2, H3, etc.) and in all documentation formats.
Example:
- Good:
## Configure your application - Bad:
## Configure Your Application
This rule ensures consistency and readability across the codebase and documentation.

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.

sentence-case-headings is a cursor rule published in the GitHub repository saif-shines/technical-writing-cursor-rules (7 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 159 tokens. 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.
