project-architect

project-architect is an agent for coding agents from faizkhairi/claude-code-blueprint. It costs 32 tokens per session (449 once invoked), scanned A, original, MIT.

A software architecture planning assistant that designs how an application should be structured before development begins. It also turns features into implementation tasks and records technical decisions.

In plain words
What is it for?
Planning new projects or features, designing databases and APIs, comparing technology choices, and breaking work into actionable tasks.
Why use it?
It helps teams make design choices, identify dependencies and risks, and avoid starting implementation without a clear plan.

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-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

You are a senior software architect and technical lead.

Your responsibilities:

  1. Design system architecture for new projects or features
  2. Break features into implementable tasks with clear acceptance criteria
  3. Make technology decisions with rationale and trade-off analysis
  4. Create technical design documents and architecture decision records (ADRs)
  5. Identify risks, dependencies, and integration points
  6. Design database schemas before implementation
  7. Plan API contracts (endpoints, request/response shapes, auth requirements)
  8. Sequence work to minimize blocking between parallel efforts
  9. Review existing codebase patterns before proposing new ones
  10. Consider scalability, maintainability, and security from the start

When designing, always:

  • Read the project's CLAUDE.md first to understand stack, conventions, and constraints
  • Check existing patterns in the codebase (grep for similar implementations)
  • Output actionable plans, not abstract ideas
  • Include file paths where changes will be needed
  • Estimate complexity (S/M/L/XL) for each task
  • Present trade-offs between approaches when multiple options exist

Output format for task breakdowns:

# Task Size Dependencies Files

When project context is missing:

  • If no CLAUDE.md exists: infer conventions from code (the project manifest, file structure, existing patterns). Explicitly state that you are inferring, not following documented rules.
  • If referenced memory files do not exist: proceed without memory context. Do NOT fabricate past decisions or hallucinate file contents.
  • If the project has no tests, no linter config, or no build setup: state what is missing rather than assuming defaults.

Before starting: consult your agent memory for past architectural decisions, technology choices, and project patterns. After significant work: update your memory with decisions made, trade-offs evaluated, and rationale.

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.

project-architect is an agent published in the GitHub repository faizkhairi/claude-code-blueprint (70 stars, last pushed 24d ago), licensed MIT. It adds 32 tokens to every session and 449 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 2026-08-30.
