with-deno-kit-context

with-deno-kit-context is a cursor rule for Cursor from zackiles/deno-kit. It costs 0 tokens per session (479 once invoked), scanned A, original, MIT.

Project-specific guidance for a command-line tool that creates new Deno 2 projects from templates. Deno is a runtime and toolkit for JavaScript and TypeScript; the guidance explains where the tool's source code and project templates live.

In plain words
What is it for?
Developing or reviewing the Deno 2 project generator, editing templates, adding scaffolded project types, and working with shared template files and placeholders.
Why use it?
It helps changes follow the scaffold tool's folder structure and ensures shared templates and project-specific templates are handled consistently.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

with-deno-kit-context 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 3d 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

Context on this Project

  • This codebase represents a CLI-based project scaffolder for Deno 2 projects (not Deno 1)
  • The CLI supports several types of projects such as an http-server, CLI, library etc...
  • Files in the folder <project-root>/src/ represent the CLI code
  • Files in the folder <project-root>/templates/ represent template files that are used to scaffold a users project and contain placeholders that the CLI replaces with values when compiling them in the users workspace for their new project
  • There is a top-level sub-folder in <project-root>/templates/ for each type of project the CLI can scaffold. E.g there is a folder named <project-root>/templates/cli that contains templates for a CLI project.
  • Templates that are shared across scaffold projects can be found in the <project-root>/templates/shared folder. If there is a conflict between a shared template and project-specifc template, the project specific template takes precedence. For example, <project-root>/templates/cli/README.md and <project-root>/templates/shared/README.md both exist, and so the project-specific one of <project-root>/templates/cli/README.md takes precesdence
  • The command file that compiles templates and scaffolds a user's project is in src/commands/init.ts. In production it will download the github release templates.zip folder which contains all the templates in templates/ as they are shown now in the codebase, unzips them, compiles them with the runtime values a user provides, and then assembles a project with them (using some of the shared templates, with some of the project-specific ones)
  • IMPORTANT: because of the nature of the templates in templates/ local development of the templates is difficult and error prone. This is because of templates having either a) placeholders and b) paths that don't represent the final compiled path on a users machine. We don't get proper intellisense and linting or typechecking the files will not work.
  • Template files deno.jsonc config file when developing locally obviously also don't work as they can't properly resolve local files such as the entry point as they don't exist when developing localling. These files only work once compiled.

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.
