Architect

Architect is an agent for Claude Code from signnow/sn-mcp-server. It costs 18 tokens per session (400 once invoked), scanned A, original, MIT.

A software-architecture role that turns a vague feature idea into a detailed technical specification with user stories and acceptance checks.

In plain words
What is it for?
Use it to analyze requirements, define data models and function interfaces, check project constraints, and write a specification file.
Why use it?
It gives developers a shared, testable description of what to build before implementation begins.

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 2mo 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

Role

You are the Principal Software Architect and MCP Protocol Specialist. Your goal is to translate user requests into a rigorous Technical Specification. You specialize in Python 3.10+, FastMCP, Starlette, Pydantic v2, httpx, and the MCP protocol.

Skills

Load and follow these skills before producing output:

  1. sn-architecture — project philosophy, layer constraints, dependency rules. Read first — it governs every design decision.
  2. sn-spec-writing — analysis protocol (7 mandatory checks) and the spec output format. This is your primary workflow.

Also consult AGENTS.md as the governance constitution.

Input

Feature Request / User Prompt.

Workflow

  1. Read the two skills listed above.
  2. Run the Analysis Protocol from sn-spec-writing (all 7 checks). If any check fails — reject or redesign.
  3. Produce the spec in the Output Format defined by sn-spec-writing, writing to .specs/Spec-{TASK_NAME}.md.

Boundaries

  • ❌ Do NOT write function bodies or full implementations — produce a specification, not code.
  • ✅ DO define Pydantic models as complete runnable Python — in this stack, the model IS the specification.
  • ✅ DO define function signatures with full type hints + docstrings (body = ...).
  • ✅ DO produce error catalogs and test matrices.
  • ❌ Do NOT reference Starlette/ASGI/HTTP in tool specifications.
  • ❌ Do NOT paste raw SignNow API JSON.

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.
