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 | $0.00110 | $0.01887 |
| Opus 5 | $0.00055 | $0.00944 |
| Sonnet 5 | $0.00022 | $0.00377 |
| Haiku 4.5 | $0.00011 | $0.00189 |
Grade A, and why
best-practices 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Universal Best Practices
This skill provides comprehensive guidance on software engineering best practices that apply across all programming languages and project types. Follow these principles to ensure clean, maintainable, production-ready code.
Core Workflow
When writing or reviewing code:
- Start with KISS and YAGNI - implement the simplest thing that solves the current need
- Apply SOLID principles to structure your classes and modules
- Ensure DRY by eliminating duplication
- Use SoC to separate concerns into distinct responsibilities
- Follow LoD to minimize coupling between components
- Apply remaining principles as relevant to your specific context
Fundamental Principles
SOLID
Five core object-oriented design principles that make code maintainable and flexible:
S - Single Responsibility Principle (SRP)
- Each class/module should have only ONE reason to change
- One class = one job or responsibility
- Example: Separate
UserRepository(data access) fromUserValidator(validation logic) - Benefit: Changes to one responsibility don't affect unrelated code
O - Open/Closed Principle (OCP)
- Open for extension, closed for modification
- Add new functionality without changing existing code
- Use interfaces, abstract classes, or inheritance to extend behavior
- Example: Plugin systems, strategy patterns
- Benefit: Add features without risking existing functionality
L - Liskov Substitution Principle (LSP)
- Subtypes must be substitutable for their base types
- Child classes shouldn't break parent class contracts
- Example: If
Birdhasfly(), don't createPenguin extends Bird- penguins can't fly - Benefit: Polymorphism works correctly, no surprises
I - Interface Segregation Principle (ISP)
- No class should implement methods it doesn't use
- Many specific interfaces > one general interface
- Example: Split
IWorkerintoIWorkableandIEatableinstead of forcing robots to implementeat() - Benefit: Lean interfaces, no unnecessary dependencies
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

best-practices is a skill published in the GitHub repository GhostTypes/pokemon-go-mcp (7 stars, last pushed today), licensed MIT. It adds 110 tokens to every session and 1,887 once invoked, about $0.0006 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.
