LLM Wiki Local API Skill

Talk to the user's locally-running LLM Wiki app over its built-in HTTP API. This is a standard JSON API — call it directly with whatever HTTP tool is already in your environment (curl, fetch, requests, http middleware, etc.). No client library to install, no SDK to learn.

Treat the wiki as a private, structured knowledge base the user has been curating: pages live as wiki/**.md, raw documents under raw/sources/, wikilinks form a graph.

When to invoke

Invoke only when the user is clearly referring to LLM Wiki specifically — by app name, by wiki framing, or by 知识库 framing. Concretely:

• asks a question framed as "what does my wiki / my knowledge base / 我的知识库 / LLM Wiki say about X"
• asks to "search my wiki / LLM Wiki project / 我的知识库 for X"
• references a wiki page by stem / title and wants to read or cross-link
• asks for the wiki graph / 知识图谱 / wiki overview / wiki structure
• has just added or edited files under the LLM Wiki source folder and wants ingest re-run / 重新索引
• says "use my wiki for context" / "ground your answer in my wiki" / "check my LLM Wiki"
• names a wiki project (by ID, by absolute path, or by current)

Do NOT invoke when the user says:

• "search my notes" without further qualification — likely Obsidian / Apple Notes / Notion / Logseq / Bear / etc.
• "find in my notebook" — likely Jupyter / OneNote / Notability
• "check my Obsidian / Notion / Roam / Logseq vault" — explicitly a different tool
• "look up my Anki / Readwise / Pocket" — different tool
• "search my files / my Documents folder" — generic filesystem, not the wiki
• general world knowledge, current events, or anything the user clearly wants from the open web

When in doubt about which knowledge tool the user means, ask: "Do you mean your LLM Wiki specifically, or another tool?" — don't silently call the LLM Wiki API on what might be an Obsidian vault.

Quick start

The whole API is plain HTTP + JSON. The fastest path:

BASE=http://127.0.0.1:19828
TOKEN="${LLM_WIKI_API_TOKEN:-<paste-from-Settings>}"
 

If you're writing TypeScript / JavaScript:

Python is the same shape — urllib.request, requests, httpx, whatever you already have. Don't install anything new.

Auth model

The API is localhost-only. The token is one of:

1. LLM_WIKI_API_TOKEN environment variable (if set, overrides UI)
2. The user's apiConfig.token saved via Settings → API Server
3. allowUnauthenticated: true mode (no token needed; rare, user opt-in only)

Always check /api/v1/health first — it returns { enabled, authConfigured, allowUnauthenticated, tokenSource }. If authConfigured: false && allowUnauthenticated: false, ask the user to open Settings → API Server → Generate new token. Do not proceed without auth being set up.

Three equivalent ways to send the token:

Never log or echo the token. Never put it in any URL the user can see in your output (Referer / shell history / logs all leak it).

Standard workflow

When the user asks "look it up in my wiki":

1. Resolve project (see Project resolution below).
2. Search: POST /api/v1/projects/{id}/search with { query, topK: 5..10 } → ranked hits (path, title, snippet, score, titleMatch, optional vectorScore, images). Inspect response.mode to know whether hybrid retrieval kicked in.
3. Read top hits: for each promising hit, GET /api/v1/projects/{id}/files/content?path=... for the full markdown. Or pass includeContent: true to the search to avoid the round-trip.
4. Cite + answer: synthesize an answer grounded in the read pages. Quote the path of each page you used so the user can verify and jump in-app.

Reading the score

The score field's scale depends on mode:

• mode: "keyword" — additive keyword score. Filename-exact hits are ~200; phrase-in-title ~50+; bag-of-tokens lands in single digits. Treat anything below ~5% of the top result as low-confidence.
• mode: "hybrid" or "vector" — RRF (Reciprocal Rank Fusion) score, typically in the 0.015–0.035 range. The absolute number is small; relative ordering is what matters. Use the per-result vectorScore (raw cosine 0–1) for "how strongly did the embedding match" if you need it.

Don't apply a fixed score threshold across modes. Sort by score descending and rely on relative gaps.

Project resolution

{id} in every project-scoped endpoint accepts four forms:

Decision tree for what the user said:

Cache the resolved id for the rest of the conversation — there's no need to re-GET /projects for every call. But if the user switches contexts mid-conversation ("now look in my Reading project"), re-resolve.

When the user is silent about which project, default to current and mention it once: "Looking in your active project (Research Notes)…". This avoids cross-project surprises.

For graph / cross-reference questions:

• GET /api/v1/projects/{id}/graph?limit=200 → { nodes: [{id, label, nodeType, path, linkCount}], edges: [{source, target, weight}] }
• Filter via ?q=term (substring of id/label, case-insensitive) and ?nodeType=entity|concept|...

For "I added new docs" requests:

• POST /api/v1/projects/{id}/sources/rescan → returns { queue: { tasks }, changedTasks: [...] }. Tell the user how many files changed. Actual ingest runs asynchronously via the desktop queue.

Endpoint contract (v1)

{id} accepts a UUID, an absolute filesystem path (URL-encoded), or the literal string current.

Error handling

Always treat the status code as the contract:

If the HTTP call itself fails (connection refused / ENOTFOUND): the desktop app is not running. Tell the user: "Launch LLM Wiki, then re-try."

Etiquette

• Cite paths. When you answer using wiki content, name the page: (from wiki/concepts/rope.md). The user uses these to verify and to jump in-app.
• Stay read-only by default. Only sources/rescan mutates state; everything else is reads. Don't invent write endpoints — they don't exist in v1.
• Don't dump full pages unless asked. Snippet + path is usually enough. Pull full content only when reasoning genuinely needs it.
• Respect the project boundary. The current project is the user's active context. Do not silently switch projects.
• Honor the rate limit. 120 req/sec is plenty for sequential work, but parallel page reads can burst close to it. Batch where the API allows (includeContent: true on search avoids N+1 reads).
• Never leak the token. Headers are safe; query params and your own output text are not.
