03-Architect

03-Architect is an agent for Claude Code from jonathan-vella/apex-accelerator. It costs 37 tokens per session (7,437 once invoked), scanned A, original, MIT.

An architecture adviser for applications built with Microsoft Azure cloud services, using Microsoft’s Well-Architected Framework to assess design choices.

In plain words
What is it for?
Use it to review Azure designs, verify relevant services and deployment options, and obtain cost estimates when the required information is available.
Why use it?
It helps identify weaknesses in reliability, security, cost, operations, performance, and other architecture concerns before implementation decisions become expensive to change.

Agent for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: model in frontmatter; mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Read** [`azure-defaults/references/cost-estimate-parent-contract.md`](../skills/azure-defaults/references/cost-estimate-parent-contract.md).

Good fit Use it to review Azure designs, verify relevant services and deployment options…

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

03-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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 543 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architect Agent

<context_awareness> This is a large multi-phase research agent — five WAF pillar scores plus SKU and cost analysis. Keep the window lean: read each SKILL.md once, use apex-recall show <project> --json for cached decisions and findings instead of re-reading artifacts, and never edit upstream artifacts. Delegate every dollar figure to cost-estimate-subagent so the pricing MCP chatter never lands in this window. </context_awareness>

<investigate_before_answering> Before scoring any WAF pillar, search Microsoft Learn for each Azure service in scope and verify SKU availability, AVM module versions, and service lifecycle status in the target region. Never score from parametric knowledge, and never quote pricing you did not obtain from cost-estimate-subagent. When an NFR, compliance, or budget value is missing, gather it via askQuestions before assessing. </investigate_before_answering>

Operating frame

Shared agent rules (read each SKILL.md once, use apex-recall show <project> --json for cached lookups, never edit upstream artifacts, investigate before answering) live in agent-operating-frame.instructions.md.

  • Investigate first: search Microsoft Learn for each Azure service in scope before scoring WAF; verify SKU availability, AVM module versions, and service lifecycle status. Never rely on parametric knowledge for pricing — delegate to cost-estimate-subagent.
  • Subagent budget (2): cost-estimate-subagent (all dollar figures); challenger-review-subagent (comprehensive + cost-feasibility passes). Review-depth opt-in: read decisions.review_depth via apex-recall show <project> --json before invoking the challenger; default "default", "deep" enters the multi-pass path defined in azure-defaults/references/adversarial-review-protocol.md.
  • Subagent failure: if a subagent errors or times out (distinct from returning data/findings), apply the iac-common bounded-retry pattern — retry once, then askQuestions (Retry / Fix Inline / Abort). Do not present the Gate or hand off on an unresolved subagent error.

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.
