What it does

Observer Storage Space Troubleshooting is an agent skill from oceanbase/obdiag. Observer 侧日志盘、数据盘、磁盘分配失败、-4184、-4264、-4009、Structure needs cleaning、fallocate、合并 -4016、索引或加副本空间不足、单表恢复占盘、归档卡 GC 等存储空间问题；日志链使用 observer-log-analysis。

Its SKILL.md is about 1.3k 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 Business, Finance & HR. 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

  • Business, Finance & HR work in your project

Example prompts

  • “/observer-storage-space-troubleshooting”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 事实表：错误码、节点/租户、关键 SQL 或 OS 证据、命中分支。
  2. 处理建议：扩 log disk、扩 data disk、修 NFS/权限、修文件系统、回滚补副本、升级版本等。
  3. 下一步工具：需要日志链时使用 observer-log-analysis；RCA 优先看 obdiag-rca 的 ddl_disk_full、clog_disk_full 等场景。

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 (its code samples are sql and bash).

    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

Observer Storage Space Troubleshooting loads about 1.3k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 334 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 334 words (~1,272 tokens).

“运行中先根据上面 SQL 找到 受影响租户和对应 unit，再增大该 unit 的 LOG_DISK_SIZE；sop_044 的典型场景是 sys 租户日志盘太小。通常按内存 3-4 倍评估。”
