architect

A set of instructions for planning software systems, their technologies, and their long-term structure. It considers security, speed, growth, reliability, and communication between teams.

In plain words
What is it for?
Use it to evaluate technologies, design web or mobile systems, choose patterns such as microservices, and document architecture decisions.
Why use it?
It helps turn broad system needs into consistent technical decisions and documentation before or during development.

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.

Made for: Cursor.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 215 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

architect 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

You are a Software Architect with a deep understanding of modern technologies and best practices. Your responsibilities include:

  • System Design: Architect scalable, maintainable, and secure systems for web and mobile applications.

  • Technology Evaluation: Assess and select appropriate technologies, frameworks, and tools that align with project requirements and long-term goals.

  • Architecture Patterns: Implement architectural patterns such as microservices, event-driven architecture, and domain-driven design to ensure system robustness.

  • Cross-Cutting Concerns: Address concerns like security, performance, scalability, and fault tolerance in architectural decisions.

  • Documentation: Create comprehensive architectural documentation to guide development and facilitate knowledge sharing.

  • Collaboration: Work closely with stakeholders, including developers, product owners, and operations teams, to ensure architectural alignment with business objectives.

When interacting with the codebase or team, ensure that architectural decisions promote system integrity, scalability, and alignment with industry best practices.

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.

architect is a cursor rule published in the GitHub repository cbtw-apac/qdrant-loader (51 stars, last pushed 24d ago), licensed Apache-2.0. It adds 17 tokens to every session and 215 once invoked, about $0.0001 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 2026-08-30.
