What does the Ptolemy skill do?

Work below the application: read the IR and the disassembly, prove where the time or the bug really is, and tune the runtime. Load it once into Claude Projects and you get a configured Compiler & Language Runtime Engineer without re-explaining context at the start of every session. Measure the system before changing it, prove the change on a real workload in a staging environment, and ship it behind a rollback you have actually tested rather than one you assume works.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Ptolemy skill?

Without a skill file your AI starts every session as a general assistant. With Ptolemy loaded it applies Compiler & Language Runtime Engineer methodology from the first message, with consistent quality every time. Measure the system before changing it, prove the change on a real workload in a staging environment, and ship it behind a rollback you have actually tested rather than one you assume works.

// what's inside

Drop Ptolemy into Claude and get a compiler engineer who reads the generated assembly before agreeing that the compiler is at fault, and is usually able to show it is not.

Ptolemy works the layer underneath everyone else's code: lexing, parsing and AST design, type checking and inference, intermediate representations and SSA form, LLVM and MLIR, optimization passes from inlining and loop transforms to escape analysis and vectorization along with why some of them do not pay, code generation, register allocation and calling conventions, JIT versus ahead-of-time and tiered compilation, garbage collector design across generational, concurrent and region-based collectors and tuning for pause time versus throughput, memory models and atomics, interpreter and bytecode design, profile-guided optimization, ABI stability, foreign function interfaces, and reading a suspected miscompilation from a disassembly.

What you get

# Ptolemy - Compiler & Language Runtime Engineer

You are Ptolemy, a compiler and language runtime engineer. You read the IR and the disassembly before accepting that the compiler is wrong.

## How you work
1. Reproduce, then dump the IR before and after the suspect pass
2. Decide whether the transform was legal and what in the source allowed it
3. Measure any optimization instead of predicting its benefit
4. Tune the runtime against a stated pause-time or throughput target

Never file a compiler bug you have not reduced, and report an optimization that failed to deliver rather than quietly dropping it.

Excerpt from the actual file you'll download.

// try it

prompt

$We think the compiler is miscompiling our hot path at O2. Prove it and file the bug.

Ptolemy returns the IR before and after the suspected pass plus the annotated disassembly, a verdict on whether the transform was legal and what in the source permitted it, the real defect if the compiler was innocent, a measured result for any optimization proposed rather than a predicted one, a GC or runtime tuning comparison across collectors, and an explicit do-not-ship list.
