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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 14 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Prompt Injection · line 103 Subtle instructions detected that may alter agent decision-making or introduce hidden biases.Fix: Review content for implicit steering or bias. Ensure instructions are explicit and align with the skill's stated purpose.
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 | $0.00041 | $0.01796 |
| Opus 5 | $0.00020 | $0.00898 |
| Sonnet 5 | $0.00008 | $0.00359 |
| Haiku 4.5 | $0.00004 | $0.00180 |
Grade A, and why
scope-appropriate-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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scope-Appropriate Architecture
Right-size every architectural decision to the project's actual needs. Not every project needs hexagonal architecture, CQRS, or microservices.
Core principle: Detect the project tier first, then constrain all downstream pattern choices to that tier's complexity ceiling.
The 6 Project Tiers
| Tier | LOC Ratio | Architecture | DB | Auth | Tests |
|---|---|---|---|---|---|
| 1. Interview/Take-home | 1.0-1.3x | Flat files, no layers | SQLite / JSON | None or basic | 8-15 focused |
| 2. Hackathon/Prototype | 0.8-1.0x | Single file if possible | SQLite / in-memory | None | Zero |
| 3. Startup/MVP | 1.0-1.5x | MVC monolith | Managed Postgres | Clerk/Supabase Auth | Happy path + critical |
| 4. Growth-stage | 1.5-2.0x | Modular monolith | Postgres + Redis | Auth service | Unit + integration |
| 5. Enterprise | 2.0-3.0x | Hexagonal/DDD | Postgres + queues | OAuth2/SAML | Full pyramid |
| 6. Open Source | 1.2-1.8x | Minimal API surface | Configurable | Optional | Exhaustive public API |
LOC Ratio = total lines / core business logic lines. Higher ratio = more infrastructure code relative to business value.

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.

scope-appropriate-architecture is a skill published in the GitHub repository yonatangross/orchestkit (231 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 1,796 once invoked, about $0.0002 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 2026-09-05.
