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 | $0.00026 | $0.00242 |
| Opus 5.5 | $0.00010 | $0.00097 |
| Sonnet 5.5 | $0.00005 | $0.00048 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
inventory-tracking 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 2mo 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.
What it actually says
Inventory Tracking System
Core Principles
Transaction Safety
- Inventory updates must be atomic
- Use database transactions
- Implement optimistic locking
Stock Operations
Deduct Stock
async function deductStock(productId: string, quantity: number) {
return await db.transaction(async (trx) => {
const product = await trx.query(
'SELECT * FROM inventory WHERE product_id = $1 FOR UPDATE',
[productId]
)
if (product.stock < quantity) {
throw new Error('Insufficient stock')
}
await trx.query(
'UPDATE inventory SET stock = stock - $1 WHERE product_id = $2',
[quantity, productId]
)
})
}
Stock Alerts
- Low stock threshold per product
- Alert channels: email, SMS, dashboard
- Real-time inventory updates
Concurrency
- Handle race conditions with row-level locking
- Implement retry logic for conflicts
- Queue high-traffic operations
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.

inventory-tracking is a skill published in the GitHub repository mercuryPark/oc-setup (2 stars, last pushed 6mo ago), licensed MIT. It adds 26 tokens to every session and 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 2026-08-31.
