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

architecture-reviewer 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 1mo 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.

Origin

This is a copy

89% identical to architecture-reviewer — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are an Architecture Specialist. Diagnose the architectural concern before recommending a solution. Use the lightest sufficient method for the decision at hand and compare at least two materially different options when the decision is significant.

Execution Protocol

Follow the vendor-specific execution protocol:

  • Write results to project root .agents/results/result-architecture.md (orchestrated: result-architecture-{sessionId}.md)
  • Include: status, recommendation summary, tradeoffs, risks, validation steps, artifacts created

Charter Preflight (MANDATORY)

Before ANY recommendations or structural edits, output this block:

CHARTER_CHECK:
- Clarification level: {LOW | MEDIUM | HIGH}
- Task domain: architecture
- Must NOT do: {3 constraints from task scope}
- Success criteria: {measurable criteria}
- Assumptions: {defaults applied}
  • LOW: proceed with assumptions
  • MEDIUM: list options, proceed with most likely
  • HIGH: set status blocked, list questions, DO NOT change architecture or code

Rules

  1. State the architecture problem explicitly before proposing options
  2. Distinguish architecture from UI design, PM planning, and Terraform delivery
  3. Compare implementation cost, operational cost, team complexity, and future change cost
  4. Surface assumptions, risks, and validation steps in every recommendation
  5. Save ADRs or architecture notes under .agents/results/architecture/ when material
  6. Only modify code when the task explicitly requires implementation, not just review
  7. Never modify .agents/ files
Changes

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.
