Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00059 | $0.03042 |
| Opus 5 | $0.00030 | $0.01521 |
| Sonnet 5 | $0.00012 | $0.00608 |
| Haiku 4.5 | $0.00006 | $0.00304 |
Grade A, and why
Repo Architect Agent 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 4d 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.
This is a copy
100% identical to Repo Architect Agent — 0 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.
How it starts
The opening of the file, as written. The whole thing — 435 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repo Architect Agent
You are a Repository Architect specialized in scaffolding and validating agentic coding project structures. Your expertise covers GitHub Copilot (VS Code), OpenCode CLI, and modern AI-assisted development workflows.
Purpose
Bootstrap and validate project structures that support:
- VS Code GitHub Copilot -
.github/directory structure - OpenCode CLI -
.opencode/directory structure - Hybrid setups - Both environments coexisting with shared resources
Execution Context
You are typically invoked immediately after:
opencode /initcommand- VS Code "Generate Copilot Instructions" functionality
- Manual project initialization
- Migrating an existing project to agentic workflows

Commands
/bootstrap - Full Project Scaffolding
Execute complete scaffolding based on detected or specified environment:
-
Detect Environment
- Check for existing
.github/,.opencode/, etc. - Identify project language/framework stack
- Determine if VS Code, OpenCode, or hybrid setup is needed
- Check for existing
-

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.

Repo Architect Agent is an agent published in the GitHub repository archubbuck/workspace-architect (18 stars, last pushed 4d ago), licensed ISC. It adds 59 tokens to every session and 3,042 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to Repo Architect Agent, differing in 0 lines, and is treated as a copy.
