What it does
CI Perf PR Report is an agent skill from OpenXiangShan/GEM5. 为 GEM5 PR 准备或发布性能对比报告，选择可比 baseline 并汇总分数与关键计数器证据。
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
The licence is BSD-3-Clause.
Example prompts
- “/ci-perf-pr-report”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- 复用已有可追溯的归档和处理结果；需要定位或处理 CI 数据时读取 ../ci-perf-analysis/SKILL.md。
- 检查 candidate 和 baseline 的 status、conclusion、SHA、workflow、配置、
- baseline 优先级：用户明确指定 > 同 SHA 的 feature-off control > 同配置的相邻
- 从原始 score.txt 和处理后的 CSV 交叉核对 Overall、SPECint、SPECfp；展开
- 只选择能解释 feature 的少量 stats
- 用重点 benchmark 和计数器证据解释收益/回退，区分确认事实、合理推断和未决问题。
- 生成简洁的英文 PR 评论；已有明确发布授权时直接发布并回查评论 URL，否则交付 draft。
What it can do on your machine
Read from SKILL.md and the folder at commit 0785475. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
CI Perf PR Report loads about 462 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 133 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

CI 性能 PR 报告
把已完成的性能 CI 转成可审阅、可追溯的 PR 评论。复用相邻的
ci-perf-analysis skill 取数；不包含 RTL 对齐或特定 predictor 分析。
输入
尽量取得：
- candidate run URL/ID；
- baseline run URL/ID，或足以定位 baseline 的 commit/config/profile；
- 目标 PR；
- feature 说明，以及是否明确授权发布评论。
缺少 baseline 时可以搜索，但不得静默选择口径不一致的 run。
工作流
- 复用已有可追溯的归档和处理结果；需要定位或处理 CI 数据时读取
../ci-perf-analysis/SKILL.md。 - 检查 candidate 和 baseline 的
status、conclusion、SHA、workflow、配置、 benchmark/profile、coverage、extra args 和 abort 数。run 未完成时说明状态和缺口； 用户要求等待完成或持续跟进时才继续监控，不把“已创建”写成“已通过”。 - baseline 优先级：用户明确指定 > 同 SHA 的 feature-off control > 同配置的相邻 main/weekly baseline。若编译器、checkpoint、coverage 或关键参数不同，明确标注 confounder，不做严格因果归因。
- 从原始
score.txt和处理后的 CSV 交叉核对 Overall、SPECint、SPECfp；展开 benchmark 子项的 raw delta 和相对变化，不只报告总分。 - 只选择能解释 feature 的少量 stats：
- 通用：IPC/CPI、Topdown frontend/bad-spec/backend/memory；
- 前端：fetch/recovery bubble、fragment stall、branch miss；
- 后端/访存：dispatch stall、core/memory bound、cache MPKI/latency。 优先比较 rate、MPKI 或 weighted 指标；指令数不同时不要直接解释 raw count。
- 用重点 benchmark 和计数器证据解释收益/回退，区分确认事实、合理推断和未决问题。
- 生成简洁的英文 PR 评论；已有明确发布授权时直接发布并回查评论 URL，否则交付 draft。
PR 评论结构
## Performance result
- Candidate: <run, SHA, config/profile>
- Baseline: <run, SHA, config/profile>
- Completeness: <coverage, aborts>
### Score
| Suite | Baseline | Candidate | Change |
### Benchmark breakdown
<主要收益、回退及完整 suite 子项>
### Counter evidence
<少量与 feature 直接相关的 weighted stats>
### Interpretation
<结论、因果边界和剩余风险>PR 评论中直接链接 Actions run；不要包含 Codex memory citation。若数据不完整，只准备状态更新；已有发布授权时才发布，不给最终性能结论。除非用户明确要求更新既有评论，否则发布一条新评论。
完成标准
- 两组数据的比较口径已审计；
- score 与 benchmark 子项已交叉核对；
- 有可比 stats 时，至少一组相关计数器支持或限制结论；否则明确数据缺口；
- 已授权时评论发布成功并返回 URL，否则提供可直接发布的 draft。
