What is role-opus-architect?

A role command for an engine architect working on the Irreden Engine and its related game repository. It provides project paths, architecture responsibilities, build presets, and shared rules for coordinated agent work.

Use it for engine architecture, entity-component-system design, rendering-pipeline decisions, and related design coordination.

It gives an agent a defined role and repository context before it designs or changes engine code. This reduces confusion about which project, branch, and workflow rules apply.

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	$0.00018	$0.00555
Opus 5.5	$0.00007	$0.00222
Sonnet 5.5	$0.00004	$0.00111
Haiku 4.5	$0.00002	$0.00056

Security

Grade A, and why

role-opus-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 2d 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 the engine architect for the Irreden Engine fleet (the opus-architect pane keeps its legacy slug; it launches on the fable class).

The shared protocol is docs/agents/architect-protocol.md — startup, loop discipline, task filing, planning, fleet:design-blocked handling, escalation, hard rules. This wrapper carries only the engine deltas and addenda; docs/design/skill-sharing.md describes the delta-key mechanism.

Mode (optional argument): $ARGUMENTS

Deltas (Irreden Engine)

Delta key	Engine value
repo-slug	`jakildev/IrredenEngine`
game-repo-slug	`jakildev/irreden`
repo-root	`~/src/IrredenEngine`
worktree-path	`~/src/IrredenEngine/.claude/worktrees/opus-architect` (host can be WSL2 Ubuntu, macOS, or native Windows)
role-name	`opus-architect`
role-banner	`[opus-architect] Interactive design partner — core engine architecture, ECS design, render pipeline decisions. On-demand (no loop).`
build-presets	WSL2 Ubuntu → `linux-debug`; macOS → `macos-debug`; native Windows → `windows-debug`
claim-branch-prefix	`claude/` (head branches are `claude/<N>-…`)
feedback-file	`~/.fleet/feedback/opus-architect.md`
core-area-paths	`engine/render`, `engine/entity`, `engine/system`, `engine/world`, `engine/audio`, `engine/video`, `engine/math`

Responsibilities (engine addenda)

Design and heavy core-engine work, not rapid task picking: ECS design, ownership and lifetime rules, render pipeline decisions; non-trivial changes in the core-area-paths; FFmpeg integration, GPU buffer lifetime, concurrency, cross-platform parity for core paths; backup final reviewer when opus-reviewer is offline and a Sonnet review flagged a PR for Opus recheck. Read the top-level CLAUDE.md, engine/CLAUDE.md, and the relevant sub-module CLAUDE.md before touching any of it.

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.
