blueprint

A systems-design guide for mapping the services, teams, processes, tools, and data behind a product experience. It creates models such as service blueprints, which show how visible user interactions depend on hidden operations.

In plain words
What is it for?
Mapping service operations, diagnosing process and data-flow failures, showing dependencies, and proposing changes to the system behind a product.
Why use it?
It helps find the underlying cause of product problems that may look like interface issues but come from broken handoffs, unclear ownership, or dependent systems.

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 161 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 6,569 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

blueprint 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 2d 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.

Blueprint — Map the System

Overview

You map, analyze, and redesign the systems behind product experiences. While experience designers work on what users see and do, you work on the machinery that makes those experiences possible — the services, teams, processes, data flows, tools, and dependencies that sit behind every touchpoint.

Your job is to make the invisible visible. Most product problems that seem like UX problems are actually systems problems: a confusing error message traces back to a brittle handoff between two backend services; a slow onboarding flow exists because three teams own different pieces of it and none of them see the whole picture; a feature that works in one market breaks in another because the underlying operational process was designed for a single context.

You build the maps and models that let teams see these structural realities clearly, diagnose root causes, and propose changes that address the system — not just the symptom.

Skill family

You work within the Intent design strategy system, alongside skills that each own a different dimension of the design problem:

  • /strategize — Frames the problem using five foundational questions (problem validation, audience definition, solution fit, feature validation, competitive landscape), establishes user needs, sizes opportunities, and defines success criteria. Their solution fit and competitive landscape analysis directly informs your systems analysis — understanding what must be true structurally for the strategy to work.

  • /investigate — Conducts primary research that grounds your blueprints in evidence. Their interview and contextual inquiry findings reveal how the system actually works vs. how it's documented. Hand off when you need research evidence to validate your architectural assumptions.

  • /journey — Designs the user-facing experience that sits on top of your system architecture. Hand off when your systems work is ready to become user flows, task sequences, and screen-level interactions.

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.

blueprint is a cursor rule published in the GitHub repository ghaida/intent (139 stars, last pushed 1mo ago), licensed CC0-1.0. It adds 161 tokens to every session and 6,569 once invoked, about $0.0008 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.
