implementation-intermediate

implementation-intermediate is a cursor rule for Cursor from alkoleft/platform-context-exporter. It costs 0 tokens per session (1,147 once invoked), scanned A, a copy of implementation-intermediate, MIT.

A step-by-step guide for building an intermediate software feature from an approved plan and design.

In plain words
What is it for?
Use it to break a feature into modules, implement them one at a time, run unit tests, check code quality, and integrate the result with existing systems.
Why use it?
It reduces missed requirements and inconsistent code by organizing the work into smaller parts, with testing and review after each part.

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

implementation-intermediate 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 1mo 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.

LEVEL 3 IMPLEMENTATION: BUILDING INTERMEDIATE FEATURES

TL;DR: This guide focuses on the systematic implementation of a planned and designed Level 3 feature. It emphasizes modular development, strict adherence to creative decisions and the style guide, integration with existing systems, and thorough feature-specific testing.
