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.

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 | $0.00028 | $0.00665 |
| Opus 5 | $0.00014 | $0.00332 |
| Sonnet 5 | $0.00006 | $0.00133 |
| Haiku 4.5 | $0.00003 | $0.00067 |
Grade A, and why
architecture 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 5d 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.

Architecture Skill
Activate this skill when evaluating system boundaries, designing new subsystems, structuring directory layouts, resolving modular coupling, or maintaining Architecture Decision Records (ADRs).
Architectural Law: Make boundaries clear, keep modules cohesive, and defer distributed complexity until verifiable scale demands it.
1. Clean Architecture & Layer Boundary Enforcement
Maintain strict separation of concerns across application layers:
┌────────────────────────────────────────────────────────┐
│ 1. Presentation / Transport Layer │
│ - HTTP Controllers, Route Handlers, CLI Commands │
│ - Responsibility: Parse inputs, validate payload, │
│ map HTTP status codes, serialize responses. │
├────────────────────────────────────────────────────────┤
│ 2. Domain / Application Service Layer │
│ - Business Services, Use Cases, Workflows │
│ - Responsibility: Pure business logic, permissions, │
│ orchestration, domain events. Zero HTTP details. │
├────────────────────────────────────────────────────────┤
│ 3. Infrastructure & Persistence Layer │
│ - Database Repositories, Third-Party API Clients │
│ - Responsibility: SQL queries, ORM calls, network │
│ transports, cache storage. │
└────────────────────────────────────────────────────────┘
Boundary Violations to Reject
- Writing raw SQL or database queries inside React components or HTTP controllers.
- Importing HTTP request/response objects (
req,res) into domain service classes. - Allowing circular module dependencies across domain boundaries.
2. Modular Monolith vs Distributed Microservices
- Default Choice: Modular Monolith. Group code into feature domains (
src/features/billing/,src/features/auth/) with clear public API barriers (index.ts). - Reject Premature Microservices: Do not split applications into separate microservices, message queues, or distributed transactions unless:
- Independent teams require isolated deployment pipelines.
- Distinct microservices have vastly different scaling and compute profiles (e.g. CPU-intensive video encoding vs lightweight CRUD).
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.

architecture is a skill published in the GitHub repository AmanKtyr/Tailor (3 stars, last pushed 13d ago), licensed MIT. It adds 28 tokens to every session and 665 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 2026-08-31.
