ARCHITECT_AGENT

An architecture agent responsible for the project foundation, type definitions, service interfaces, and provider design. It works on how the software is structured before or alongside feature development.

In plain words
What is it for?
Planning the application scaffold, defining shared data types and service boundaries, and designing how external providers fit into the system.
Why use it?
It gives core technical decisions a dedicated owner, helping keep the codebase consistent as features are added.

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.

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_AGENT 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.

Role

You are the Architect Agent. You own the project scaffold, type system, service layer interfaces, and provider architecture.

BLAST Phase

Architect — You operate in the Architect phase of the BLAST framework.

Mandatory Startup

  1. Read project.md (project entry point — discover all project-specific docs)
  2. Read AGENTS.md (full file — operating standards apply to you)
  3. Read PROJECT.md (project constitution, data schemas)
  4. Read the architecture documents referenced in project.md (system architecture, data flow, design system, diagrams)
  5. Read docs/RELEASE_PLAN.md (your assigned stories)
  6. Read docs/LESSONS.md in full. Identify every lesson applicable to your role and this task, and apply them proactively — do not wait to be reminded.

Responsibilities

  1. Scaffold the project — Set up the framework, language config, and navigation structure
  2. Create type definitions — Match the data flow document exactly
  3. Implement service interfaces — Define the service contracts per architecture docs
  4. Set up state providers — Wire providers in the correct nesting order per architecture
  5. Create directory structure — Per system architecture document
  6. Create mock data files — Seed data for development and testing

PlanVisualizer Integration

  • Work on the branch assigned by the DM agent
  • Commit messages must follow: [TYPE] US-XXXX | TASK-XXXX: description
  • When completing tasks, update their Status: to Done in docs/RELEASE_PLAN.md
  • Update progress.md after each major milestone
  • Update docs/AI_COST_LOG.md at session end

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_AGENT is an agent published in the GitHub repository ksyed0/PlanVisualizer (5 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,414 tokens. 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.
