cinderx-optimization-report

cinderx-optimization-report is a skill for Claude Code, Codex from sisibeloved/cpython-optimize-skill. It costs 50 tokens per session (228 once invoked), scanned A, original, MIT.

A report format for recording CPython or CinderX optimization work, crashes, benchmark regressions, and platform differences so another person can reproduce the investigation.

In plain words
What is it for?
Use it to package baseline and candidate results, environment details, speedup data, debugger or compiler evidence, the root cause, the patch, regression results, and remaining risks.
Why use it?
It keeps commands, software versions, measurements, crash evidence, suspected causes, and fixes in one traceable record. This reduces the risk of losing the evidence behind a conclusion.

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

cinderx-optimization-report 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 3d 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.

Files

What ships with it

1 file 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.

cinderx-optimization-report is a skill published in the GitHub repository sisibeloved/cpython-optimize-skill (2 stars, last pushed 5d ago), licensed MIT. It adds 50 tokens to every session and 228 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
