Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00031 | $0.00918 |
| Opus 5 | $0.00015 | $0.00459 |
| Sonnet 5 | $0.00006 | $0.00184 |
| Haiku 4.5 | $0.00003 | $0.00092 |
Grade A, and why
grepai-installation 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GrepAI Installation
This skill covers all methods to install GrepAI on any platform.
When to Use This Skill
- Installing GrepAI for the first time
- Upgrading an existing GrepAI installation
- Building GrepAI from source
- Verifying a successful installation
Prerequisites
- macOS/Linux: Terminal access
- Windows: PowerShell
- From source: Go 1.24+ installed
Installation Methods
Method 1: Homebrew (macOS - Recommended)
The easiest way to install on macOS:
# Add the tap and install
brew install yoanbernabeu/tap/grepai

- Automatic updates with
brew upgrade grepai - Clean uninstall with
brew uninstall grepai - Manages dependencies automatically
Method 2: Shell Script (Linux/macOS)
Universal installation script:
# Download and run the installer
curl -sSL https://raw.githubusercontent.com/yoanbernabeu/grepai/main/install.sh | sh
# Verify installation
grepai version
What the script does:
- Detects your OS and architecture
- Downloads the appropriate binary
- Installs to
/usr/local/bin/ - Sets executable permissions
Method 3: PowerShell (Windows)
Native Windows installation:
# Run in PowerShell (Admin recommended)
irm https://raw.githubusercontent.com/yoanbernabeu/grepai/main/install.ps1 | iex
# Verify installation
grepai version
Note: You may need to adjust execution policy:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Method 4: Build from Source
For developers or custom builds:
# Clone the repository
git clone https://github.com/yoanbernabeu/grepai.git
cd grepai
# Build the binary
make build
# Install globally
sudo mv ./bin/grepai /usr/local/bin/
# Verify installation
grepai version
Requirements:
- Go 1.24 or later
- Make (optional, can use
go builddirectly)
Verifying Installation
After installation, verify everything works:
# Check version
grepai version
# Output: grepai version 0.24.0
# Check available commands
grepai --help
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.
