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 | $0.00242 | $0.00242 |
| Opus 5 | $0.00121 | $0.00121 |
| Sonnet 5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
RulePort typescript-standards.instructions.md scanned grade A with 1 finding 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.

Expected in a hook, worth knowing in a rule or an instructions file.
- Minimize external dependencies. Usage of native `fs`, `path`, and `child_process` is preferred. What it actually says
TypeScript Standards
Syntax
- Use ES Modules (
import/export) for all TypeScript files. - Use
constfor variables that don't change,letfor those that do. Avoidvar. - Use String Interpolation (Template Literals) over concatenation.
- Use Interfaces for object definitions and public contracts.
- Use Explicit Return Types for public functions to ensure stable contracts.
Async Patterns
- Prefer
async/awaitover raw.then()chains. - Always wrap top-level await implementations or main execution logic in try/catch blocks.
Error Handling
- Scripts must exit with
process.exit(1)on fatal errors. - console.error messages should be prefixed with an emoji (e.g., ❌) for visibility in terminal logs.
Dependencies
- Minimize external dependencies. Usage of native
fs,path, andchild_processis preferred. yamlis the only strictly required 3rd party dependency for parsing.- Use
vitestfor testing.
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.

RulePort typescript-standards.instructions.md is an instructions file published in the GitHub repository lewiesnyder/RulePort (2 stars, last pushed 5mo ago), licensed MIT. It adds 242 tokens to every session, about $0.0012 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
