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 | $0.00026 | $0.02242 |
| Opus 5.5 | $0.00010 | $0.00897 |
| Sonnet 5.5 | $0.00005 | $0.00448 |
| Haiku 4.5 | $0.00003 | $0.00224 |
Grade A, and why
grepai-languages 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 7d 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 — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GrepAI Supported Languages
This skill covers the programming languages supported by GrepAI for indexing and call graph analysis.
When to Use This Skill
- Checking if your language is supported
- Configuring language-specific settings
- Understanding trace capabilities per language
- Troubleshooting language-related issues
Supported Languages Overview
GrepAI indexes files with a built-in list of extensions (source code, config and documentation). Other extensions can be added with chunking.custom_extensions. Binary files, minified files (such as *.min.js) and files larger than 1 MB are skipped.

Language Configuration
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.

grepai-languages is a skill published in the GitHub repository yoanbernabeu/grepai-skills (20 stars, last pushed 8d ago), licensed MIT. It adds 26 tokens to every session and 2,242 once invoked, about $0.0001 per session on Opus 5.5. 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.
