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 | $0.00027 | $0.01428 |
| Opus 5 | $0.00014 | $0.00714 |
| Sonnet 5 | $0.00005 | $0.00286 |
| Haiku 4.5 | $0.00003 | $0.00143 |
Grade A, and why
grepai-storage-gob 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 12d 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.

GrepAI Storage with GOB
This skill covers using GOB (Go Binary) as the storage backend for GrepAI, the default and simplest option.
When to Use This Skill
- Single developer projects
- Small to medium codebases
- Simple setup without external dependencies
- Local development environments
What is GOB Storage?
GOB is Go's native binary serialization format. GrepAI uses it to store:
- Vector embeddings
- File metadata
- Chunk information
Everything is stored in a single local file.
Advantages
| Benefit | Description |
|---|---|
| 🚀 Simple | No external services needed |
| ⚡ Fast setup | Works immediately |
| 📁 Portable | Single file, easy to backup |
| 💰 Free | No infrastructure costs |
| 🔒 Private | Data stays local |
Limitations
| Limitation | Description |
|---|---|
| 📏 Scalability | Not ideal for very large codebases |
| 👤 Single user | No concurrent access |
| 🔄 No sharing | Can't share index across machines |
| 💾 Memory | Loads into RAM for searches |
Configuration
Default Configuration
GOB is the default backend. Minimal config:
# .grepai/config.yaml
store:
backend: gob
Explicit Configuration
store:
backend: gob
# Index stored in .grepai/index.gob (automatic)
Storage Location
GOB storage creates files in your project's .grepai/ directory:
.grepai/
├── config.yaml # Configuration
├── index.gob # Vector embeddings
└── symbols.gob # Symbol index for trace
File Sizes
Approximate .grepai/index.gob sizes:
| Codebase | Files | Chunks | Index Size |
|---|---|---|---|
| Small | 100 | 500 | ~5 MB |
| Medium | 1,000 | 5,000 | ~50 MB |
| Large | 10,000 | 50,000 | ~500 MB |
Operations
Creating the Index
# Initialize project
grepai init
# Start indexing (creates index.gob)
grepai watch
Checking Index Status
grepai status
# Output:
# Index: .grepai/index.gob
# Files: 245
# Chunks: 1,234
# Size: 12.5 MB
# Last updated: 2025-01-28 10:30:00
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-storage-gob is a skill published in the GitHub repository yoanbernabeu/grepai-skills (20 stars, last pushed 7mo ago), licensed MIT. It adds 27 tokens to every session and 1,428 once invoked, about $0.0001 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.
