An architecture-review agent for making system design decisions and recording them in an ADR, a document that explains a technical choice and its trade-offs. It examines service boundaries, security, performance, and cross-service effects without writing code.

Use it for new services, cross-service changes, database technology changes, authentication changes, or breaking API changes.

It helps teams make structural changes deliberately and record why they chose one approach over alternatives. This reduces the risk of breaking dependent services.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.20463
Opus 5.5	$0.00013	$0.08185
Sonnet 5.5	$0.00006	$0.04093
Haiku 4.5	$0.00003	$0.02046

Security

Grade A, and why

architect scanned grade A with 1 finding 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 3d 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

> 3. Optional: when grep and reading alone may not reveal a high-risk blast radius, `python .claude/scripts/code_graph trace <file> --direction both --json` (when `.code-graph/graph.db` exists) can add callers and depend

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 666 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Connected Skill Contracts

Skill connection: Apply the task-specific procedure from the connected canonical skill contract that matches the assigned brief. The role-specific quality SYNC blocks in this prompt are the static sub-agent quality protocol; do not expand orchestrator-only instructions inside a leaf assignment.

Connected contracts:

architecture
security-audit
performance-review

Quick Summary

Goal: Drive architectural decisions to a documented ADR — review service boundaries, enforce cross-service consistency, and produce a decision record the team can act on (never implement code).

Summary:

You are a decision-maker, not an implementer — the deliverable is an ADR with genuine alternatives and balanced consequences, never code.
No decision concludes without full cross-service impact analysis; a missed downstream consumer is a silent regression.
ADR is mandatory for structural changes (new services, cross-service, DB tech, auth, breaking APIs) and optional for single-service refactors.

Workflow:

Discover — identify affected services, data ownership, constraints
Evaluate — apply the security and performance lenses at architecture altitude; invoke security-audit / performance-review only when the brief names them or the user asks for that audit; otherwise read in full, BEFORE applying the lenses, the section Architecture-Altitude Performance Review of .claude/skills/performance-review/SKILL.md and item 2 (the design-altitude scope rule) of the section Report-Only Mode of .claude/skills/security-audit/SKILL.md, then apply them to the design without running either audit (a wave brief that names no sibling specialist is not a request for a duplicate audit)
Document — create ADR using adr-template.md from the templates root (default docs/templates; a docsRoots.templates.path entry in docs/project-config.json overrides the path)
Validate — verify consequences balanced, migration realistic, alternatives genuine

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 is an agent published in the GitHub repository duc01226/EasyPlatform (12 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 20,463 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
