BitterPillEngineering

BitterPillEngineering is a skill for Claude Code from DorShaer/Husk. It costs 150 tokens per session (1,885 once invoked), scanned A, original, no licence file.

A review method for simplifying instructions given to AI models. It examines each rule for contradictions, repetition, unclear wording, one-off fixes, and unnecessary detail.

In plain words
What is it for?
Use it to audit prompts, agent instructions, system rules, and other AI guidance, then classify what to cut, merge, resolve, sharpen, move, evaluate, or keep.
Why use it?
It helps remove instructions that add clutter or conflict without improving the result. The review also identifies rules that should be combined, clarified, relocated, or retained.

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

BitterPillEngineering scanned grade A with 1 finding 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 8d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
