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 | $0.00020 | $0.00274 |
| Opus 5.5 | $0.00008 | $0.00110 |
| Sonnet 5.5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
add-language-rules 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 1mo 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
100% identical to add-language-rules — 6 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
/add-language-rules
Use this workflow when working on add-language-rules in everything-claude-code.
Goal
Adds a new programming language to the rules system, including coding style, hooks, patterns, security, and testing guidelines.
Common Files
rules/*/coding-style.mdrules/*/hooks.mdrules/*/patterns.mdrules/*/security.mdrules/*/testing.md
Suggested Sequence
- Understand the current state and failure mode before editing.
- Make the smallest coherent change that satisfies the workflow goal.
- Run the most relevant verification for touched files.
- Summarize what changed and what still needs review.
Typical Commit Signals
- Create a new directory under rules/{language}/
- Add coding-style.md, hooks.md, patterns.md, security.md, and testing.md files with language-specific content
- Optionally reference or link to related skills
Notes
- Treat this as a scaffold, not a hard-coded script.
- Update the command if the workflow evolves materially.
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.
