Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00020 | $0.01414 |
| Opus 5 | $0.00010 | $0.00707 |
| Sonnet 5 | $0.00004 | $0.00283 |
| Haiku 4.5 | $0.00002 | $0.00141 |
Grade A, and why
arch-init 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.

Attune Architecture-Aware Init Command
Research-driven project initialization that selects appropriate architectural paradigms based on project needs.
When To Use
Use this command when you need to:
- Start a new project with architecture guidance
- Choose between architectural paradigms (hexagonal, clean, etc.)
- Get research-backed architecture recommendations
- Initialize project with paradigm-specific templates
- Understand trade-offs of different architectures
When NOT To Use
Avoid this command if:
- Architecture already decided (use
/attune:project-initdirectly) - Simple project without architectural complexity
- Modifying existing project structure
- Standard patterns sufficient without special architecture
Usage
# Interactive mode (recommended) - guides through architecture selection
/attune:arch-init --name my-project
# Specify language and let it recommend architecture
/attune:arch-init --name my-project --lang python
# Specify both language and architecture
/attune:arch-init --name my-project --lang python --arch hexagonal
# Accept recommended architecture without prompting
/attune:arch-init --name my-project --lang python --accept-recommendation
What This Command Does
-
Gathers project context:
- Project type (Web API, CLI, data pipeline, etc.)
- Domain complexity
- Team size and experience
- Non-functional requirements
- Timeline constraints
-
Researches best practices:
- Searches for current industry standards (2026)
- Identifies emerging patterns
- Notes anti-patterns to avoid
- Finds technology-specific considerations
-
Recommends architecture paradigm from 14 available options:
- Layered Architecture
- Functional Core, Imperative Shell
- Hexagonal (Ports & Adapters)
- Modular Monolith
- Microservices
- Service-Based Architecture
- Event-Driven Architecture
- CQRS + Event Sourcing
- Serverless
- Space-Based Architecture
- Pipeline Architecture
- Microkernel Architecture
- Client-Server Architecture
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.

arch-init is a command published in the GitHub repository athola/claude-night-market (337 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 1,414 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
