Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00063 | $0.00705 |
| Opus 5 | $0.00032 | $0.00352 |
| Sonnet 5 | $0.00013 | $0.00141 |
| Haiku 4.5 | $0.00006 | $0.00071 |
Grade A, and why
obsidian scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian
Work with Obsidian vaults — they are just folders of plain Markdown files.
When to Use
✅ USE this skill when:
- "Search my notes for X"
- "Create a new note about Y"
- "Find all notes tagged with Z"
- "Move this note to a different folder"
- "List my recent notes"
When NOT to Use
❌ DON'T use this skill when:
- Notion pages → use
notionskill - Non-Markdown documents → use appropriate file tools
- Obsidian plugin settings → edit
.obsidian/config directly - Google Docs → use
google_workspaceskill
Vault Location
Obsidian vaults are normal folders on disk. Common locations:
- macOS:
~/Documents/Obsidian/,~/Library/Mobile Documents/... - Linux:
~/Documents/Obsidian/,~/Notes/ - Windows:
%USERPROFILE%\Documents\Obsidian\
On macOS, vault paths are tracked in:
~/Library/Application Support/obsidian/obsidian.json
Commands
Find the vault path
python {skill_path}/obsidian_vault.py locate
Search note titles
python {skill_path}/obsidian_vault.py search "query"
Search note content
python {skill_path}/obsidian_vault.py search-content "query"
Create a new note
python {skill_path}/obsidian_vault.py create "Folder/Note Title" --content "# My Note\n\nContent here"
List notes in a folder
python {skill_path}/obsidian_vault.py list "folder/path"
List recent notes
python {skill_path}/obsidian_vault.py recent --limit 10
Direct file editing
Since Obsidian notes are plain Markdown, you can always edit them directly:
# Read a note
cat ~/Documents/Obsidian/MyVault/Notes/example.md
# Append to a note
echo "## New Section" >> ~/Documents/Obsidian/MyVault/Notes/example.md
Obsidian will pick up changes automatically.
Wikilinks
Obsidian uses [[wikilinks]] for inter-note links. When moving or renaming
notes, consider updating links in other files that reference the moved note.
Notes
- Vault = normal folder; no special tools needed for basic operations
- Config lives in
.obsidian/(workspace + plugin settings) — usually don't touch - Avoid writing to hidden dot-folders via Obsidian URI
- Multiple vaults are common (work/personal, iCloud/local)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

obsidian is a skill published in the GitHub repository ericwang915/PythonClaw (41 stars, last pushed 24d ago), licensed MIT. It adds 63 tokens to every session and 705 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
