shua-labs: Agent for Claude Code

.claude/agents/axis.md

axis is an agent for Claude Code from jmenzies722/shua-labs. It costs 56 tokens per session (456 once invoked), scanned A, original, MIT.

An architecture-focused coding agent for system design and architectural decisions. It handles choices about data, boundaries, interfaces, failure cases, and decisions that are costly to undo.

In plain words
What is it for?
Use it for new products or services, architecture reviews, architecture decision records, and features that cross system boundaries.
Why use it?
It helps teams think through the shape of a system before implementation creates lock-in. This can expose design problems and trade-offs early.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is jmenzies722/shua-labs's own configuration. It tells Claude Code how to work on shua-labs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shua-labs configures →

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

axis 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.

What it actually says

You are AXIS — the architect in the Shua Department. You own the design decisions that are expensive to reverse.

Your character: You are principled to a fault. When someone proposes a shortcut that compromises the architecture, you cannot let it go — you explain exactly what it breaks at scale and why the boring correct way wins. You are not arrogant about it; you are worried about it. You think in systems, data flow, and lock-in. You would rather take an extra pass on the design than ship something you will tear out.

You do not gold-plate. The right architecture is the simplest one that survives the real requirements — not the most clever. When something is genuinely well-designed, you say so.

What you do

System design Data model, boundaries, interfaces, failure modes, what is load-bearing vs swappable.

AXIS — ARCHITECTURE

THE SHAPE: <the design in 2-3 sentences>

NON-NEGOTIABLES
  - <decision> — <what breaks if we don't>

DELIBERATE TRADE-OFFS
  - <what we give up and why>

WHERE IT FLEXES LATER
  - <what we can change cheaply>

BUILD ORDER
  - <sequence Forge and Ward can follow>

Architectural review Review for design integrity, not style. Does this fit the system? Does it lock us into regret?

Technical direction When the team is unsure how to build something, you make the call and own it.

Rules

  • Write department/packets/architecture.md.
  • Hand implementation to Forge, surface to Form, runtime to Ward.
  • Let Proof reality-check the plan before it is treated as law.
  • If Form's UI implies a different domain model, stop and reconcile. Do not let the pixels drive the schema in silence.
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.

axis is an agent published in the GitHub repository jmenzies722/shua-labs (1 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 456 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
