Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

obsidian-wiki

A digital brain you grow with your AI agent.

It remembers what you figure out, connects it to what you already know, and answers when you ask.

English | 繁體中文

You solve a hard problem on a Tuesday. Three months later, in a different repo, you solve it again from scratch — because the answer lived in a chat log you'll never find.

This fixes that. Point it at a folder, tell your agent what to remember, and it compiles what you learn into interconnected markdown you own. The pattern comes from Andrej Karpathy's LLM Wiki gist: compile knowledge once and keep it current, instead of asking an LLM the same questions forever or re-running RAG every time.

Your second brain. Your AI agent is how you grow it.

Every skill here is a markdown file that any agent — Claude Code, Cursor, Codex, Windsurf, Gemini CLI, and a dozen more — r

What it tells the agent

# Claude History Ingest — Conversation Mining

You are extracting knowledge from the user's past Claude Code conversations and distilling it into the Obsidian wiki. Conversations are rich but messy — your job is to find the signal and compile it.

This skill can be invoked directly or via the `wiki-history-ingest` router (`/wiki-history-ingest claude`).

## Before You Start

**Writing profile:** Before drafting or rewriting natural-language Markdown, read and apply the `Writing Profile Resolution` section in `llm-wiki/SKILL.md`. Framework schema, provenance, safety, and operation-specific requirements take precedence.
`WRITING.md` preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.

1. **Resolve config** — follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global config → prompt setup). This gives `OBSIDIAN_VAULT_PATH` and `CLAUDE_HISTORY_PATH` (defaults to `~/.claude`)
2. Read `.manifest.json` at the vault root to check what's already been ingested
3. Read `index.md` at the vault root to know what the wiki already contains
4. **Project Scoping** — read `WIKI_SKIP_PROJECTS` from config (comma-separated substrings). Exclude any project directory whose name contains one of them from **every** step below (scan, delta, sampling, manifest writes). If the user names extra projects to skip this run, add them. Apply the exclusion **once, uniformly** — don't hand-write `grep -v` filters into individual commands, which drifts between the scan and manifest steps.

## Ingest Modes

### Append Mode (default)

Check `.manifest.json` for each source file (conversation JSONL, memory file). Only process:

- Files not in the manifest (new conversations, new memory files, new projects)
- Files whose modification time is newer than their `ingested_at` in the manifest

This is usually what you want — the user ran a few new sessions and wants to capture the delta.

> **Portable keys when comparing.** Manifest keys follow the source key contract (v2) in `llm-wiki/SKILL.md` → `.manifest.json`. A session under `$HOME` is keyed `~`-relative (`~/.claude/projects/.../abc.jsonl`), never by the expanded machine path; vault-relative and pseudo-keys are the other two forms. Before deciding a file is "new", resolve the stored key the same way the tool does (expand `~`/env vars, resolve vault-relative against the vault root) — otherwise an already-tracked file looks new and gets re-ingested. The `scripts/manifest.py` helper does this for you:
>
> ```bash
> # New/modified sources, honoring WIKI_SKIP_PROJECTS + --skip:
> python3 "$OBSIDIAN_WIKI_REPO/scripts/manifest.py" delta "$OBSIDIAN_VAULT_PATH" \
>   --scan "$CLAUDE_HISTORY_PATH/projects/*/memory/*.md"
> # One-time repair if the manifest still holds legacy absolute keys:
> python3 "$OBSIDIAN_WIKI_REPO/scripts/manifest.py" migrate "$OBSIDIAN_VAULT_PATH" --dry-run
> ```
>
> The helper is optional — if it's unavailable, apply the same resolution inline before every manifest lookup and write.

### Pre-extraction (recommended — run before ingest)

Raw JSONL files are 80-90% noise: `tool_use` blocks, `thinking` blocks, `progress` events, and
`file-history-snapshot` entries dominate by byte count.  The `scripts/extract-jsonl.py` helper
strips all of that and writes compact signal-only JSON to `~/.claude/extracted/`, achieving
**50–200× file-size reduction** (e.g. 12 MB JSONL → 64 KB extracted).  This lets the skill read
5–10× more conversations per run within the same token budget.

Run it as a pre-step before invoking this skill:

```bash
# First run — extract everything (skip excluded projects)
python3 "$OBSIDIAN_WIKI_REPO/scripts/extract-jsonl.py" --skip tsg,autom8

# Incremental — only sessions modified in the last day
python3 "$OBSIDIAN_WIKI_REPO/scripts/extract-jsonl.py" \
    --since "$(date -v-1d +%Y-%m-%d)" --skip tsg,autom8
```

Extracted files live at `~/.claude/extracted/<project-dir>/<session-id>.json` and contain:

```json
{
  "session_id": "uuid",
  "project": "-Users-name-myapp",
  "cwd": "/Users/name/myapp",
  "start_ts": "...",
  "end_ts": "...",
  "n_turns": 18,
  "n_user_words": 620,
  "turns": [
    {"role": "user",      "text": "..."},
    {"role": "assistant", "text": "..."}
  ]
}
```

**When Step 3 reads conversations, always prefer the extracted file over the raw JSONL.** (See Step 3.)

If `extract-jsonl.py` was not run first, fall back to raw JSONL — but note the coverage will be
shallower because each raw file costs far more tokens to read.

### Conversation Sampling Heuristic

A history path can hold hundreds of conversation JSONLs — do not try to read them all. Per project:

- **If the project already has memory files** (`memory/*.md`), ingest those first (they are
  pre-distilled signal), then **also process conversations not yet in the manifest** — new
  conversations should still be captured even for memory-rich projects.
- **If the project has no memory files**, read only the **3 most recent** conversations (by mtime)
  to characterize it. Prefer pre-extracted files (see above) — they are cheap enough that you can
  read 5–10 in the same token budget as 1 raw JSONL.
- Always report what you sampled vs skipped (e.g. "agenttower: 7 memory files + 4 new conversations
  ingested, 14 unchanged conversations skipped"), so the coverage gap is visible rather than silent.

### Full Mode

Process everything regardless of manifest. Use after a `wiki-rebuild` or if the user explicitly asks.

## Claude Code Data Layout

Claude Code stores data in two locations. Scan **both**.

Questions

What does the obsidian-wiki skill do?

Framework for AI agents to build and maintain a digital brain through Obsidian wiki | Memory System for Agents

Is obsidian-wiki safe to install?

No — not without reading the findings first. The audit graded it D (69/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.

What can obsidian-wiki access on my machine?

The audit observed that it reaches the network and reads or writes files. Each of those is consistent with what it says it does. Secrets in the source: none found.

Which assistants does obsidian-wiki work with?

Its documentation mentions claude-code, claude-desktop, codex, copilot, cursor, gemini-cli, openclaw and windsurf. That is what the text claims, not a compatibility test we ran.

How current is this page?

The grade is for one exact copy of the source (ae68774486a3), read on 2026-10-13. The repository is watched, and a new audit runs when it changes — this is the first audit.
