What it does
Obdiag Performance is an agent skill from oceanbase/obdiag. 性能类采集与主机 IO：ASH、AWR、perf 火焰图、sysstat、磁盘 IO。在用户说卡顿、慢、会话堆积、要看 ASH/AWR/火焰图或主机负载时使用；与 observer-sql-analysis、observer-log-analysis 互补。
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering SQL. It works with SQL. The repository describes itself as: obdiag (OceanBase Diagnostic Tool) is designed to help OceanBase users quickly gather necessary information and analyze the root cause of the problem.
When your agent uses it
- Tasks that involve SQL
Example prompts
- “/obdiag-performance”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- gather_ash：设定与现象匹配的时间窗；看等待类、top SQL。
- 若需历史报告包：gather_awr（时间窗与租户/集群参数按环境）。
- 若怀疑主机资源：gather_sysstat；若怀疑磁盘：tool_io_performance。
- 完成标准：已能说明「主要等待/资源瓶颈」或已明确需 observer-sql-analysis / observer-log-analysis 跟进。
What it can do on your machine
Read from SKILL.md and the folder at commit e912c58. 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.
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
Obdiag Performance loads about 642 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 161 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.
SKILL.md
Its licence (MulanPSL-2.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 161 words (~642 tokens).
