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 | $0.00229 | $0.00229 |
| Opus 5 | $0.00114 | $0.00114 |
| Sonnet 5 | $0.00046 | $0.00046 |
| Haiku 4.5 | $0.00023 | $0.00023 |
Grade A, and why
naming-conventions 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.
This is a copy
97% identical to naming-conventions — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
File Naming Conventions
Kebab Case for File Names
All files in this project should use kebab-case for naming. This means:
- All lowercase letters
- Words separated by hyphens
- No spaces or underscores
- No PascalCase or camelCase
Examples:
✅ Good:
base-tool.tsgoogle-search-tool.tsexit-loop-tool.tsllm-agent.tsmemory-service.ts
❌ Bad:
BaseTool.tsGoogleSearchTool.tsexit_loop_tool.tsLlmAgent.tsmemoryService.ts
Class and Interface Naming
While files use kebab-case, TypeScript classes and interfaces should still follow standard conventions:
- Classes and Interfaces: PascalCase (e.g.,
class BaseTool,interface ToolConfig) - Methods and Properties: camelCase (e.g.,
runAsync(),getDeclaration())
Implementation Note
This standardization helps maintain consistency across the codebase and aligns with common TypeScript ecosystem practices.
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.

naming-conventions is a cursor rule published in the GitHub repository HeiSir2014/duckduckgo-mcp-server (3 stars, last pushed 5mo ago), licensed MIT. It adds 229 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to naming-conventions, differing in 2 lines, and is treated as a copy.
