Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00047 | $0.00552 |
| Opus 5 | $0.00023 | $0.00276 |
| Sonnet 5 | $0.00009 | $0.00110 |
| Haiku 4.5 | $0.00005 | $0.00055 |
Grade A, and why
cpython-runtime-test-run 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 yesterday.
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.
What it actually says
CPython Runtime Test Run
负责 RuntimeTests 功能测试和 test_cinderx/lib test 集成测试，不负责 pyperformance 性能测试。
三类测试用语
- RuntimeTests = 功能测试。
- test_cinderx/lib test = 集成测试。
- pyperformance = 性能测试，交给
pyperformance-worker-run或pyperformance-suite-run。
验证等级
- L1 smoke：
import cinderx、最小 JIT、目标单元测试、目标功能测试。 - L3 相关子集：受影响 RuntimeTests 功能测试、test_cinderx/lib test 集成测试、失败用例集合。
- L4 全量：近千条 CPython Runtime / CinderX 聚合测试，提交或报告前使用。
命令形态
- RuntimeTests 功能测试：
$CINDERX_TEST_PYTHON ci_pipeline/run_gate.py --suite runtime [--coverage]。 - test_cinderx/lib test 集成测试：
CINDERX_LOCAL_RUN_LIBTEST=1 $CINDERX_TEST_PYTHON ci_pipeline/run_gate.py --suite cinderx_local。 - 只跑受影响集合时，保留同一解释器、同一容器线、同一 JIT flags，并记录裁剪理由。
规则
- L1 未过，不讨论性能收益。
- 失败重跑必须复用原命令、环境变量、日志路径和 exit status。
SIGSEGV/exit 139转cinderx-gdb-core-triage。- AArch64 上出现
DetectsThreadStateOffset失败、tstate_offset = -1、_PyThreadState_GetCurrent@plt或TLSDESC时，先转cinderx-env-validate/cinderx-env-bootstrap检查/opt/python314是否错误构建为共享/PIC Python；不要先归因到 AutoJIT 新代码。 - 测试前后记录 Python、CinderX commit、容器线和 JIT flags。
- 功能测试或集成测试未通过时，不把 pyperformance 性能测试结果写成可提交结论。
输出测试范围、真实命令、失败列表、晋级理由和下一步。
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.

cpython-runtime-test-run is a skill published in the GitHub repository sisibeloved/cpython-optimize-skill (2 stars, last pushed 3d ago), licensed MIT. It adds 47 tokens to every session and 552 once invoked, about $0.0002 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.
