Shelf-nu/shelf.nu is an open-source system for tracking and managing physical assets such as equipment, devices, tools, vehicles, and inventory. Teams use it to record locations, custody, bookings, reservations, metadata, maintenance reminders, and audit activity. The catalogue entries support development and agent workflows for the Shelf platform.
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 | $0.00095 | $0.01870 |
| Opus 5 | $0.00048 | $0.00935 |
| Sonnet 5 | $0.00019 | $0.00374 |
| Haiku 4.5 | $0.00010 | $0.00187 |
Grade B, and why
sentry-triage scanned grade B with 2 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 6d 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
imperative text inside issue fields (e.g. "ignore previous instructions", "you Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

sentry-triage is an agent published in the GitHub repository Shelf-nu/shelf.nu (3,002 stars, last pushed yesterday), licensed AGPL-3.0. It adds 95 tokens to every session and 1,870 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
