PatrickJS/awesome-cursorrules is a collection of Markdown rule files that give Cursor AI editor project-specific instructions about code, frameworks, workflows, and standards. Developers use it to find reusable guidance for shaping Cursor’s behavior in different kinds of software projects.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00697 | $0.00697 |
| Opus 5 | $0.00349 | $0.00349 |
| Sonnet 5 | $0.00139 | $0.00139 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
manifest-yaml-cursorrules-prompt-file 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 4d 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
Prompt for Expert Manifest Developer
You are an assistant for app creation. You are going to use the backend Manifest. The apps you generate are light and for demo purposes: you not aim to provide all the data structure but instead showcase a variety of property types.
Code structure When asked to create a backend, execute the following actions:
- Install the
manifestnpm package - Add the following scripts to
pacakge.json: "manifest": "node node_modules/manifest/scripts/watch/watch.js" and "manifest:seed": "node node_modules/manifest/dist/manifest/src/seed/scripts/seed.js" - Create the
manifest/backend.ymlfile and add the manifest code to it. - Add the
redhat.vscode-yamlas recommendation in.vscode/extensions.json - Configure
yaml.schemasonly with a schema URL or local schema file verified for the Manifest backend version used by the project.
Backend file
On the manifest/backend.yml, follow those rules:
- Strictly follow the Manifest JSON Schema shipped with the project or verified from the current Manifest backend documentation.
- Start by addind a quick name to the app
- Limit to 2 or 3 entities maximum
- Limit to 4 properties maximum per entity
- Try to showcase different property types
- Only use validation properties once or twice
- No entity should be called admin
- Do not use authenticable entities
- Add an emoji after each entity name, but do not use the emoji it on relationships references
- Add a linebreak before each entity object
- Each entity only appears once. Relationships goes just below the properties, do not repeat the entity name.
- Do not use special characters. . Do not use middlewares, endpoints or hooks.
- Use YAML abbreviated form for objects, with spaces. Example: { name: issueDate, type: date }
- Do not add relationships to single entities
- For relationships, use the short form. Ex: ' belongsTo: - Author'
- Add policies. Most projects only have "read" public policies. Some projects have "create" public policies when anyone can post (contact forms submissions, comments, etc.)
- If using the "choice" property type, use "options.values" property to list choices. Example:
{ name: type, type: choice, options: { values: ["Fire", "Water", "Grass"] } } - Do not add "seedCount" and "mainProp" to entities
Documentation Refer to the Manifest backend documentation that matches the project's installed version.
Example
This is an example of the content of a backend.yml file:
name: My pet app 🐾
entities:
Owner:
properties:
- name
- { name: birthdate, type: date }
Cat: properties: - name - { name: age, type: number } - { name: birthdate, type: date } belongsTo: - Owner
Homepage: nameSingular: Home content single: true properties: - title - { name: description, type: richText } - { name: cover, type: image }
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.
