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.

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 | $0.00134 | $0.01061 |
| Opus 5 | $0.00067 | $0.00531 |
| Sonnet 5 | $0.00027 | $0.00212 |
| Haiku 4.5 | $0.00013 | $0.00106 |
Grade A, and why
accelint-ts-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 11d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
JavaScript and TypeScript Best Practices
Comprehensive coding standards for JavaScript and TypeScript applications, designed for AI agents and LLMs working with modern JavaScript/TypeScript codebases.
Note: This skill focuses on general best practices, TypeScript patterns, and safety. For performance optimization, use the accelint-ts-performance skill instead.
When to Use This Skill
This skill provides expert-level patterns for JavaScript and TypeScript code. Load AGENTS.md to scan rule summaries and identify relevant optimizations for your task.
How to Use
This skill uses a progressive disclosure structure to minimize context usage:
1. Start with the Overview (AGENTS.md)
Read AGENTS.md for a concise overview of all rules with one-line summaries organized by category.
2. Load Specific Rules as Needed
When you identify a relevant pattern or issue, load the corresponding reference file for detailed implementation guidance:
Quick Start:
- quick-start.md - Complete workflow examples with before/after code
General Best Practices:
- naming-conventions.md - Descriptive names, qualifier ordering, boolean prefixes
- functions.md - Function size, parameters, explicit values
- control-flow.md - Early returns, flat structure, block style
- state-management.md - const vs let, immutability, pure functions
- return-values.md - Return zero values instead of null/undefined
- misc.md - Line endings, defensive programming, technical debt
- code-duplication.md - Extract common patterns, DRY principle, when to consolidate
TypeScript:
- any.md - Avoid any, use unknown or generics
- enums.md - Use as const objects instead of enum
- type-vs-interface.md - Prefer type over interface
- bundler-paths.md - Use statically analyzable import and file-system paths for optimal bundling
What ships with it
21 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.
- 11d ago First seen · 88 lines · 134 tokens per session scan A fa7d87c215f1
accelint-ts-best-practices is a skill published in the GitHub repository gohypergiant/agent-skills (24 stars, last pushed yesterday), licensed Apache-2.0. It adds 134 tokens to every session and 1,061 once invoked, about $0.0007 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 2026-08-30.
