# BitterPillEngineering

Find the instructions your model never needed in the first place

## What this does

Instruction files for AI tend to grow: rules pile up, some contradict, some the model would do anyway. This goes through them and asks of each rule whether a smarter model would need it, then sorts them into keep, cut, merge, and the rest. Reach for it when your setup file has quietly got long and you are not sure what still earns its place.

### Top 3 things it does for you

- Audit a bloated instruction file for dead weight
- Check a single file's rules quickly
- Decide which rules to cut, merge, or sharpen

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About BitterPillEngineering

This audits an AI instruction set for over-prompting. The core test it applies is simple: would a smarter model make this rule unnecessary?

Every rule goes through five questions - does the model already do this, does it contradict something, is it redundant, was it a one-off fix, is it vague - and then gets classified as CUT, RESOLVE, MERGE, EVALUATE, SHARPEN, MOVE or KEEP.

There are two ways to run it: Audit across a full system, reporting token savings, or QuickCheck against a single file. The principle behind it is that less scaffolding produces better output. It is not for attacking the logic of an idea; its own notes send you to RedTeam for that.

## Questions

### Is BitterPillEngineering safe to install?

AIR scanned this exact version of BitterPillEngineering and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 47df8eebf08d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/bitterpillengineering.

### How do I install BitterPillEngineering?

Open https://airmarket.ai/app/bitterpillengineering on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/danielmiessler/LifeOS/tree/47df8eebf08d78a3ef5851ec2f9b751bae6558fb/LifeOS/install/skills/BitterPillEngineering. Install from that link, not the branch.
