code-structure

A set of rules for organizing application code, including file layout, naming, exports, tests, dependencies, and separation of responsibilities.

In plain words
What is it for?
Use it when creating or reviewing TypeScript modules, components, and features. It covers practices such as keeping tests beside code, avoiding circular dependencies, and separating business logic from API calls or user-interface rendering.
Why use it?
It gives a team a shared structure, making code easier to find, read, change, and test.

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.

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

code-structure 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.

What it actually says

Code Structure

  • [MUST] No default exports, only named exports
  • Organize by features/domains as top-level folders
  • Write tests in adjacent tests folders.
  • Use consistent folder structure within features
  • Group related files in a single directory
  • Limit file size to maintain readability (max ~80 lines)
  • One component/module per file
  • Separate business logic from side effects like API calls or UI rendering
  • Keep configuration separate from implementation
  • Avoid circular dependencies
  • Minimize the visibility scope of functions and variables
  • Consider organizing files by their role in the application (services, utils, controllers, etc.)
  • Keep directory nesting to a minimum (max 3-4 levels deep)
  • Types should be relegated to "types" subfolders located in adjacent folders to their production code
  • Follow the naming pattern *.type.ts for type files
  • Interface names should not start with "I" prefix

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.

code-structure is a cursor rule published in the GitHub repository tbreeding/jira-mcp (6 stars, last pushed 1y ago), licensed MIT. It adds 209 tokens to every session, about $0.0010 per session on Opus 5. 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.
