# Deno
> Deno is a secure JavaScript/TypeScript runtime built on V8 and Rust,
> distributed as a single binary. TypeScript, formatting, linting, testing, and
> a standard library work with zero configuration. Programs are sandboxed by
> default; capabilities (network, filesystem, etc.) are granted explicitly via
> --allow-* flags. Deno natively supports npm packages and Node.js built-in
> modules.

Opening blockquote
Deno is a secure JavaScript/TypeScript runtime built on V8 and Rust, distributed as a single binary. TypeScript, formatting, linting, testing, and a standard library work with zero configuration. Programs are sandboxed by default; capabilities (network, filesystem, etc.) are granted explicitly via
Context architecture
How the content is divided
5 H2 sections organize 36 parsed Markdown links. 1 links point to .md or .markdown paths; 2 link occurrences use another hostname. Linked destinations have not been recursively validated.
| H2 section | Links | UTF-8 bytes | Tokens |
|---|---|---|---|
| RuntimeLine 15 | 13 | 1697 | 420 |
| DeployLine 31 | 3 | 336 | 84 |
| SandboxLine 37 | 5 | 612 | 145 |
| ExamplesLine 45 | 7 | 860 | 220 |
| OptionalLine 55 · Optional | 4 | 439 | 109 |
Link counts exclude parsed fenced and inline code and resolve relative destinations against the final endpoint. Section sizes cover the text below each H2 until the next H2.
Embedded material
Code, installation and API examples
- Fenced blocks
- 0 closed
- Declared languages
- No fenced blocks detected
- Package-install commands
- 0 detected in fenced or inline code
- Authentication examples
- 0 fenced lines match API-key, Authorization, Bearer, OAuth or access-token patterns
- HTTP request examples
- 0 fenced lines match request-method patterns
- Authentication links
- 0 links have authentication-related labels
Embedded example text and links to further documentation are counted separately. A code block does not establish that a sample runs or that an authentication flow succeeds.
Publisher prioritization
The Optional section
1 H2 section named “Optional” contain 4 parsed links. 32 links sit outside those sections. That puts 11.1% of the file’s parsed links under Optional.
The community proposal uses Optional by convention for secondary links that can be skipped for a shorter context. This label does not establish that everything outside it is critical, or that the material inside it is deprecated.
Machine-readable routes
MCP references and configuration text
No MCP or Model Context Protocol term was detected in the captured file. 0 links have MCP-related labels or paths. 0 fenced lines match mcpServers, mcp_servers or an mcp add command.
These are text and link observations. No MCP server connection, authentication or tool call was tested.
Index and bundle
llms-full.txt companion
Not established
A verified text response establishes a companion at the checked URL. It does not prove the bundle contains all product documentation, that generation is automated, or that it fits an assistant’s context window.
Change evidence
What can be said about freshness
This capture establishes a baseline. Update frequency cannot be determined from one observation.
File changes can reveal documentation edits or navigation changes. They do not by themselves measure product release velocity, accuracy, agent adoption or AI visibility.

Counts use a deterministic parser, not a spec-compliance grade. Unusual Markdown and indented code can fall outside its recognized patterns. See the llms.txt proposal and tokenizer implementation.
