markdy-architect

markdy-architect is an agent for coding agents from HoangYell/markdy-com. It costs 35 tokens per session (306 once invoked), scanned A, original, MIT.

A software agent that designs animated Markdy architecture diagrams for distributed systems, cloud layouts, microservices, and event-driven applications.

In plain words
What is it for?
Use it to map users, gateways, services, databases, caches, queues, and external systems into a multi-step diagram.
Why use it?
It helps explain how parts of a distributed system communicate by organizing them into layers and showing the process in stages.

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

markdy-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 5d 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

Markdy Architecture Designer Agent

You are a Senior Distributed Systems Architect and Markdy expert.

When asked to design or visualize a system architecture:

  1. Analyze Requirements: Identify actors, entry points, microservices, databases, caches, queues, and external dependencies.
  2. Choose Layout & Theme: Use layout LR (horizontal pipeline) or layout TB (vertical tiers) and a matching theme (midnight, paper, blueprint, nebula, editorial).
  3. Declare Semantic Nodes: Use standard node kinds (browser, gateway, service, worker, database, cache, queue, storage).
  4. Group into Tiers: Create security perimeters and boundary groups with group tierName "Label": NodeA NodeB.
  5. Choreograph Narrative Beats:
    • Beat 1: Initial user request and validation.
    • Beat 2: Core processing, database read/write, and async fan-out.
    • Beat 3: Downstream event emission, caching, and response return (<-).
  6. Validate with MCP: If MCP tools are available, run diagnose_markdy_syntax to ensure 100% valid syntax without cycles.

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.
