dsh-obsidian-vault

Obsidian vault tools for DeepSeek Harness.

An Obsidian vault is a folder of Markdown files. This plugin lets the agent work on that folder directly: read and search notes, create and edit them, manage YAML frontmatter, query by tag, and rename notes without breaking the [[wikilinks]] that point at them. Obsidian does not need to be running and no Obsidian plugin is required.

Install

dsh plugin --profile web add dsh-obsidian-vault

Or straight from GitHub:

dsh plugin --profile web add github:jinferth/dsh-obsidian-vault

Restart the profile, then confirm the tools loaded:

dsh --profile web --dump-config

Configure the vault

The vault is resolved automatically:

1. config.vaultPath in cordis.patch.yml
2. the OBSIDIAN_VAULT environment variable
3. the vault Obsidian last opened, read from its own registry (%APPDATA%\obsidian\obsidian.json on Windows, ~/Library/Application Support/obsidian/obsidian.json on macOS, $XDG_CONFIG_HOME/obsidian/obsidian.json on Linux)

To pin one vault, add a config block:

- insert:
    - id: obsidian-vault
      name: dsh-obsidian-vault
      config:
        vaultPath: '/home/me/Obsidian'
        maxResults: 200

maxResults (default 200) caps how many notes obsidian_list and obsidian_search return at once.

Tools

Tool	What it does
obsidian_info	Absolute vault path, whether it exists, note count. Call this first when unsure which vault is connected.
obsidian_list	List notes, optionally limited to a folder or filtered by a glob (Projects/**, *.md).
obsidian_read	Read one note by vault-relative path; .md may be omitted. Line numbers match obsidian_edit.
obsidian_search	Search note titles and bodies, literally or with regex.
obsidian_new	Create a note with optional frontmatter. Refuses to overwrite an existing note.
obsidian_append	Append Markdown to the end of a note, creating it when absent.
obsidian_edit	Four modes: replace (literal, must be unique unless replaceAll), replaceLines, insertLines, deleteLines.
obsidian_frontmatter	get / set / delete one frontmatter key without touching the body.
obsidian_query	Find notes by frontmatter properties, tags and path; tags are ANDed.
obsidian_move	Move or rename a note and, by default, rewrite every wikilink in the vault that points at it.
obsidian_delete	Move a note into the vault's .trash folder instead of unlinking it.
obsidian_insert_image	Copy an image into the vault and reference it from a note.
obsidian_batch	Run several of the above as one transaction: if any step fails, earlier steps are rolled back.

Safety behaviour

• Paths stay inside the vault. Absolute paths and .. traversal are rejected with a VaultPathError, so a malformed tool call cannot touch the rest of the disk.
• Application state is off limits. .obsidian/, .trash/ and .git/ are never listed, searched or written.
• Writes are atomic. Content goes to a temporary file which is then renamed over the target, so an interrupted run cannot truncate a note.
• Encoding is preserved. A CRLF file stays CRLF and a BOM stays a BOM; an edit does not turn one field into a whole-file diff in Git.
• Deletion is recoverable. obsidian_delete moves the note into .trash.

Compatibility with DeepSeek Harness releases

Harness is in developer preview and its plugin API may change. This plugin is built to survive that:

• It imports nothing from @deepseek-ai/*. All imports are Node built-ins. There is no dependency range that a Harness release can invalidate, and no lockfile to drift.
• It touches exactly one host surface: ctx.tools.register(definition). Tool schemas are plain data objects, not values produced by a version-pinned helper such as defineTool.
• It degrades instead of throwing. If the tool registry is missing, or the host rejects one definition, the plugin logs a message naming the contract it expected and keeps the rest of the profile running. It never fails the boot.
• No vault configured is not a crash. Tools explain how to configure one instead of throwing during load.

If a future release does change the tool contract, the failure mode is a [dsh-obsidian-vault] ... line in the log naming what broke, not a dead profile.

Tests

npm test

Runs 25 checks against a throwaway vault: tool registration, create/read/edit, frontmatter fidelity, CRLF and BOM preservation, wikilink rewriting on move, .trash deletion, path-escape rejection, and the compatibility behaviour above. No network, no Obsidian, no real vault.

中文速览

把 Obsidian 笔记库交给 Agent 操作：列出、检索、新建、按行号片段编辑、读写 frontmatter、按标签查询；重命名笔记时自动改写全库双链；删除进 .trash 可恢复。 写入是原子的，保留 CRLF 与 BOM。插件不导入任何 @deepseek-ai/* 包，只调用 ctx.tools.register，因此 Harness 升级不会因依赖版本范围把插件打挂；即使宿主 接口变动，也只是日志里出现一行提示，不会让 profile 起不来。

装好后如果提示未配置库：在 Obsidian 里打开一次库，或设置 OBSIDIAN_VAULT， 或在 cordis.patch.yml 里写 config.vaultPath。
