general-principles

general-principles is a cursor rule for Cursor from tbreeding/jira-mcp. It costs 209 tokens per session, scanned A, original, MIT.

A set of coding rules for keeping a codebase clear and consistent. It emphasizes small single-purpose functions, functional patterns, immutable data, meaningful names, and explicit error handling.

In plain words
What is it for?
Use it to guide implementation and code review across a project, especially when deciding how to structure functions, conditions, errors, names, and constants.
Why use it?
It gives developers shared standards for reducing repetition, hidden side effects, deeply nested logic, and hard-to-maintain code.

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

general-principles 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

General Principles

  • Follow clean coding principles
  • Prefer functional programming patterns
  • Use errors as objects pattern, avoid throwing exceptions unless absolutely necessary
  • Follow Single Responsibility Principle - each function should do one thing well
  • Follow Single Level of Abstraction Principle - operations within a function should be at the same level of abstraction
  • Abstract compound conditions into separate, well-named functions
  • Use pure functions whenever possible - no side effects, same output for same input
  • Maintain immutability - avoid modifying data; create new copies instead
  • Prefer early returns over nested conditionals
  • Keep functions small and focused (under 15-20 lines)
  • Use meaningful naming - functions should be verbs, variables should be nouns
  • Avoid abbreviations - full names improve readability
  • No magic numbers/strings - use named constants
Changes

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.

general-principles 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.
