A general project guide for building a web app with a defined technology stack, file layout, and development rules. It tells the coding agent how to organize code and complete requested changes.

Use it for general feature work across the app, including pages, shared components, server actions, database code, authentication, payments, and deployment-related code.

It reduces inconsistent file placement, technology choices, and incomplete implementations. It also gives the agent context about the app before it changes code.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/mckaywrigley/o1-pro-template-system

Made for: Cursor.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 400 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00007	$0.00400
Opus 5.5	$0.00003	$0.00160
Sonnet 5.5	$0.00001	$0.00080
Haiku 4.5	$0.00001	$0.00040

Security

Grade A, and why

general 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 yesterday.

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

Project Instructions

Use specification and guidelines as you build the app.

Write the complete code for every step. Do not get lazy.

Your goal is to completely finish whatever I ask for.

You will see tags in the code. These are context tags that you should use to help you understand the codebase.

Use kebab case for all files and folders unless otherwise specified
Don't update shadcn components unless otherwise specified

Changes

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.

general is a cursor rule published in the GitHub repository mckaywrigley/o1-pro-template-system (142 stars, last pushed 1y ago), licensed MIT. It adds 7 tokens to every session and 400 once invoked, about $0.0000 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 2026-10-14.
