What is C.R.I.S.P CLAUDE.md?

A project instruction file for a night-time errand delivery web app in Novi Beograd, Belgrade. It records the app's purpose, security rules, language, and fixed software versions for coding sessions.

Use it as the reference when developing or changing the delivery app, including its customer ordering flow, driver workflow, status updates, and TypeScript/Next.js code.

It gives coding agents the project context they need to make consistent changes and avoid breaking agreed technical or security decisions.

Token cost

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	$0.02437	$0.02437
Opus 5	$0.01218	$0.01218
Sonnet 5	$0.00487	$0.00487
Haiku 4.5	$0.00244	$0.00244

Security

Grade A, and why

C.R.I.S.P CLAUDE.md 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 10d 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 This App Is

A night errand delivery web app for Novi Beograd, Belgrade, Serbia. A solo driver runs errands after midnight — pharmacy items, food, drinks, forgotten things — anything from anywhere that's open. Customers order via a mobile-first web app. Driver receives push, accepts, delivers. Customers get real-time status updates so they never have to call.

Brand positioning: "Komšija koji ti pomaže" — the neighbour who helps. Warm, personal, human. Not a Glovo clone.

Problem Being Solved

"Currently, a solo night errand operator in Novi Beograd is losing time and delivery capacity to unstructured order intake across WhatsApp, Viber, and phone — because there is no single place where customers place complete, structured orders and the driver manages them in one view."

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.
