project-context

project-context is a cursor rule for Cursor from oakensoul/nextjs-cursor-prompts. It costs 32 tokens per session (1,108 once invoked), scanned A, original, MIT.

A project-context rule that tells the agent to consult an LLMs.mdc documentation file when it does not understand the codebase well enough.

In plain words
What is it for?
It guides initial work in unfamiliar projects and helps maintain consistency with existing code and practices.
Why use it?
It reduces guesses about the project's structure, conventions, tests, and development process.

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

project-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 6d 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.

Project Context Reference Rule

When you lack sufficient context about this project's structure, patterns, conventions, or development practices, consult the project documentation in LLMs.mdc for comprehensive guidance.

🎯 RULE OBJECTIVES:

  1. ENSURE comprehensive understanding of project context before making changes
  2. PREVENT assumptions about project structure and conventions
  3. MAINTAIN consistency with established project practices
  4. REDUCE errors from insufficient background knowledge
  5. ACCELERATE onboarding to project-specific patterns

🔍 WHEN TO APPLY THIS RULE:

Context Insufficiency Indicators:

  • Unfamiliar with project architecture or file organization
  • Unclear about coding standards or conventions used
  • Uncertain about testing patterns or requirements
  • Don't understand deployment or development workflow
  • Need background on project scope and objectives
  • Unsure about dependencies or technology stack decisions
  • Lack understanding of existing component patterns
  • Need clarity on API design principles
  • Uncertain about database schema or data patterns

Mandatory Consultation Scenarios:

  • First time working with this codebase
  • Complex refactoring or architectural changes
  • Integration work with existing systems
  • New feature development that touches multiple areas
  • Performance optimization requiring system understanding
  • Security implementations needing context about data flow
  • API changes affecting multiple consumers

📋 CONSULTATION PROCESS:

STEP 1: Context Assessment

Before starting any significant work:

  • Evaluate current understanding of the project
  • Identify knowledge gaps that could affect the task
  • Determine consultation necessity based on task complexity

STEP 2: Documentation Review

When context is insufficient:

  • Read LLMs.mdc thoroughly for project overview
  • Focus on sections relevant to your current task
  • Note key patterns and conventions to follow
  • Understand constraints and architectural decisions

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.

project-context is a cursor rule published in the GitHub repository oakensoul/nextjs-cursor-prompts (4 stars, last pushed 1y ago), licensed MIT. It adds 32 tokens to every session and 1,108 once invoked, about $0.0002 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 2026-09-03.
