What it does
Migrate Tags is an agent skill from benoror/obsidianos_work. Migrate body-level hashtags to frontmatter tags: lists so Bases can filter on them. Idempotent — leaves files that already have frontmatter tags alone.
Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Obsidian. The repository describes itself as: ObsidianOS - Work Vault. The licence is MIT.
Example prompts
- “/migrate-tags”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3c7923e. 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.
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
Migrate Tags loads about 850 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 382 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.

Migrate Tags
Usage
/migrate-tags— Scan vault, present a migration plan, prompt to confirm./migrate-tags <path>— Migrate a single file./migrate-tags <folder>— Migrate all.mdfiles under a folder./migrate-tags --dry-run— Show what would change without writing.
Why this skill exists
Obsidian supports two tag styles:
- Body tags:
#frontendwritten inline in note text. - Frontmatter tags: a YAML
tags:list at the top of the file.
Bases can filter on the frontmatter style (file.hasTag("frontend")) but not the body style reliably. Migrating one to the other makes tags queryable in Bases views — e.g. a "People with #mobile tag" view becomes trivial once everyone's @Name.md has tags: [mobile].
This skill is a one-shot migration utility plus an ongoing cleanup tool for new notes.
Workflow
Step 1: Discover candidates
Use obsidian tags format=json to enumerate all tags + their usage counts and source files. Identify files where:
- A body
#tagexists, AND - The same tag is NOT already present in frontmatter
tags:.
These are the migration candidates.
Step 2: Present the plan
Show a numbered table grouped by file:
| # | File | Body tags to migrate | Existing frontmatter tags |
|---|------|----------------------|---------------------------|
| 1 | Teams/People/@Jane Doe.md | #team-engineering, #backend | (none) |
| 2 | Teams/People/@John Smith.md | #team-engineering, #remote | (none) |
| 3 | Misc/Reading.md | #to-read, #book | (none) |Ask the user: "all", "1,2", "none", or per-file picks.
Step 3: Apply migration
For each confirmed file:
- Read the file body, collect all
#tagpatterns (respecting word boundaries —#tagnothttps://foo.com/path#section). - Use
obsidian property:set name=tags value='["a","b","c"]' type=list path="<file>"to write the frontmatter list. Iftags:already exists, merge (don't overwrite). See frontmatter-mutations. - Optionally remove the body
#tagpatterns (default: leave them — Obsidian indexes both, body tags don't hurt). Add a--strip-bodyflag for users who want clean bodies.
Show full SKILL.md (127 more words)Show less
Step 4: Verify
Run obsidian property:read name=tags path="<file>" on each migrated file to confirm the write. Spot-check that no tags were lost.
Step 5: Commit
See /commit. Commit message: chore: migrate body #tags to frontmatter tags: list (N files).
Important Notes
- Idempotent: re-running on already-migrated files is a no-op.
- Don't strip body tags by default — users may rely on visible tags in the body for in-note navigation. Opt-in via
--strip-body. - Tag normalization: leave tag names as-is. Don't auto-convert
#team-engineering→team-engineering(the leading#is stripped automatically; nothing else). - Nested tags (
#team/engineering) are preserved. - Tags inside code blocks are skipped — they're literal, not Obsidian tags.
- After running on People files,
People.baseper-team views can usefile.hasTag("team-X")as an alternative to thefile.hasLink(file("Teams/+X.md"))filter (which works but is more verbose).
