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 | $0.00479 | $0.00479 |
| Opus 5 | $0.00239 | $0.00239 |
| Sonnet 5 | $0.00096 | $0.00096 |
| Haiku 4.5 | $0.00048 | $0.00048 |
Grade A, and why
cursor-rules-location 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 yesterday.
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.

Cursor Rules Location
Rules for placing and organizing Cursor rule files in the repository.
actions:
-
type: reject conditions:
- pattern: "^(?!\.\/\.cursor\/rules\/.*\.mdc$)" message: "Cursor rule files (.mdc) must be placed in the .cursor/rules directory"
-
type: suggest message: | When creating Cursor rules:
-
Always place rule files in PROJECT_ROOT/.cursor/rules/:
.cursor/rules/ ├── your-rule-name.mdc ├── another-rule.mdc └── ... -
Follow the naming convention:
- Use kebab-case for filenames
- Always use .mdc extension
- Make names descriptive of the rule's purpose
-
Directory structure:
PROJECT_ROOT/ ├── .cursor/ │ └── rules/ │ ├── your-rule-name.mdc │ └── ... └── ... -
Never place rule files:
- In the project root
- In subdirectories outside .cursor/rules
- In any other location
-
examples:

Bad: Rule file in wrong location

Good: Rule file in correct location

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.
