What obsidian-wiki does

obsidian-wiki follows the compile-once knowledge base idea: the agent reads your sources and writes interlinked Markdown pages into an Obsidian vault you own, instead of re-answering from scratch each time. The core commands are wiki-setup, wiki-capture (save what you just worked out), wiki-ingest (documents, PDFs, transcripts, URLs), wiki-query (answers with wikilink citations), wiki-update (distill the repo you are in), plus wiki-lint, wiki-dedup, wiki-digest and wiki-narrate for upkeep and summaries.

A family of history-ingest skills mines past sessions from Claude Code, Codex, Copilot, Hermes, OpenClaw and Pi, and session-search helps find a conversation you cannot name. There are 40 skills averaging about 14 KB, some with a reference file, and an optional Python CLI installed with pip that also registers two session hooks (skip with --no-hooks). The Claude Code plugin install ships skills only. The README says no API key or network is needed because the vault is Markdown on disk. The pack also bundles a copy of a skill-creator toolkit with eval scripts. Quality depends on how well your agent follows long procedural prompts.

Good for

  • Keeping a persistent, searchable second brain in Obsidian
  • Turning past agent sessions and project docs into reusable notes
  • People who want memory stored as plain files they can read and diff

Not for

  • Teams that need a hosted or shared knowledge service
  • Users who do not use Obsidian or Markdown vaults

What's inside depth 3/5

40 skills averaging 14 KB with some reference files, a Python CLI and a bundled eval toolkit, but few scripts tied to the wiki skills themselves.

Security review

Review before installing

A set of Obsidian knowledge-vault skills that ingest your documents and past agent session logs (Claude, Codex, Copilot and others) into a markdown wiki. The pip-installed CLI registers session hooks by default unless you pass --no-hooks, the setup skill can fetch and register a Stop hook from the main branch, and an optional daily maintenance job installs a launchd, systemd or cron schedule. History ingestion reads other tools' local transcripts, and vault git sync pushes to a remote you choose.

Worth knowing

  • installs_hooksobsidian-wiki setup (pip/uv/pipx path) also registers two documented session hooks (session start and stop capture) by default; the README says to pass --no-hooks to skip them, and the wiki-setup skill asks before installing the Stop hook. The hook and CLI code are not in our files.README.md:48
  • Runs remote code at an unpinned versionIf the hook script is not found locally, the skill has the agent curl wiki-stop-capture.sh from the repo's main branch into ~/.config/obsidian-wiki/hooks, chmod +x it and register it as a Claude Code Stop hook; the skill asks the user first (line 267) and the file is not pinned to a commit..skills/wiki-setup/SKILL.md:298
  • Changes files outside your projectMerges a Stop hook into ~/.claude/settings.json, writes global config under ~/.config/obsidian-wiki, and daily-update/SKILL.md (line 136) installs a launchd agent, systemd user timer or crontab entry for a daily 9 AM maintenance run..skills/wiki-setup/SKILL.md:309
  • Installs packages or toolsInstall is pip install obsidian-wiki (or uv/pipx), which provides the CLI and hooks; the plugin route ships skills only.README.md:41
  • Relies on a CLI or package we could not reviewDepends on the obsidian-wiki Python CLI (setup, sync, sync-setup commands) and optionally qmd, none of whose code is in our files; obsidian-wiki sync stages, commits and pushes the vault to a git remote you configure (opt-in)..skills/wiki-setup/SKILL.md:360

What we checked

The repository (556 files) on Oct 29, 2026. Not a full review: 470 of 556 files were not downloaded (large repository; we reviewed the skill folders); we read 0 of 10 code files; it relies on code outside the repository: the obsidian-wiki PyPI package / CLI, scripts/daily-update.sh, hooks/wiki-stop-capture.sh and the session hooks (470 of 556 files were not downloaded); qmd CLI; history-ingest skills read local session stores of other agents (~/.claude/projects, Claude Desktop sessions, ~/.codex, Copilot, Hermes, OpenClaw, Pi) and distill them into the vault; they tell the agent to redact secrets, and this reading was not exercised.

NVIDIA SkillSpector static scan: 51 pattern hits (Rogue Agent 12, Agent Snooping 11, Supply Chain 10, Privilege Escalation 5, Dangerous Code Execution 3, Excessive Agency 3). The 51 hits include 10 'Concealed Executable Artifact' matches on the bundled skill-creator scripts, an 'ignore previous instructions' phrase inside wiki-ingest's trust-boundary section that tells the agent to treat sources as data, agent-config path mentions in history-ingest docs, and the skill-creator's os.environ copy for claude -p. Hook install, scheduler and curl steps are recorded as flags.

Can it run unattended?

Not really. Ingest and upkeep skills run on request and ask before including sensitive material; there is no autonomous loop.

FAQ

What is obsidian-wiki?

It is a set of 40 agent skills that build and maintain an Obsidian vault as a linked knowledge base. The agent ingests documents and chat history, then answers questions with wikilink citations.

How do I install obsidian-wiki?

Run pip install obsidian-wiki then obsidian-wiki setup --vault ~/brain, or install it as a Claude Code plugin with /plugin marketplace add Ar9av/obsidian-wiki. Then tell your agent to set up the wiki.

Does obsidian-wiki send my notes anywhere?

The README says there is no network, no API key and no vector store; the vault is local Markdown. Your agent's own model provider still sees whatever the agent reads.
