At a glance
Answers questions from a local Obsidian-style wiki by reading its index first, then the relevant pages, and replying with wiki-link citations instead of model memory.
- Asking what your notes say about a topic
- SKILL.md covers 核心目标, 触发场景, 降级策略 and 检索与综合流水线, plus 2 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Looking up a past decision recorded in the wiki
What it does
The skill triggers on /query or on natural questions about your notes, past decisions or knowledge base. The agent must start by reading wiki/index.md to find relevant entities, concepts, sources and syntheses, then read the best pages in full and answer with double-bracket page citations, quoting original text in block quotes and citing a page once at the start and end of a paragraph.
Answers from model memory are forbidden. If the wiki has nothing relevant, the agent has to say that the local knowledge base had no match before giving a general answer. A substantial answer, one longer than two paragraphs or comparative in nature, prompts a question about saving it as a synthesis page under wiki/syntheses, registered in the index, and every query ends with an entry appended to wiki/log.md in the format set by CLAUDE.md. The SKILL.md is written in Chinese.
When your agent uses it
- Asking what your notes say about a topic
- Looking up a past decision recorded in the wiki
- Getting an answer that cites wiki pages with double-bracket links
- Saving a valuable multi-paragraph answer as a synthesis page
Example prompts
- “/query my notes on the caching decision”
- “Look up what I decided last quarter about vendor selection in my knowledge base.”
- “Summarize what the wiki says about onboarding and offer to save it as a synthesis.”
Requirements
- A local wiki folder with wiki/index.md, wiki/log.md and a CLAUDE.md schema
What it can do on your machine
Read from SKILL.md and the folder at commit 18f4e71. 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
Wiki Vault Query loads about 383 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 97 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 97 words (~383 tokens).
- name
- query
- user-invocable
- true
