fullstack-developer-intelligent

A set of coding guidelines for building complete applications across the user interface, server, and database. It also covers connecting APIs and adding authentication, which controls who can access an app.

In plain words
What is it for?
Use it for end-to-end features, frontend-to-backend API integration, database design, authentication, and other work that crosses application layers.
Why use it?
It helps coordinate changes that span several parts of an application. This reduces the risk of treating frontend, backend, and database work as unrelated pieces.

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.

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.

Security

Grade A, and why

fullstack-developer-intelligent 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 2d 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 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.

fullstack-developer-intelligent is a cursor rule published in the GitHub repository shahshrey/cursor-hub (14 stars, last pushed 7mo ago), with no licence file. It adds 99 tokens to every session and 2,693 once invoked, about $0.0005 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.
