OpenAgent is a self-hostable personal AI assistant that combines language models, document-based retrieval, and autonomous agent loops. It lets people connect model providers and their own knowledge bases, then have agents browse the web, run code, use computers, and call MCP-compatible tools.
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 5.1 | $0.00022 | $0.00635 |
| Opus 5.5 | $0.00009 | $0.00254 |
| Sonnet 5.5 | $0.00004 | $0.00127 |
| Haiku 4.5 | $0.00002 | $0.00064 |
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 1mo 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.
This is a copy
91% identical to obsidian — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Obsidian
Obsidian vault = a normal folder on disk.
Vault structure (typical)
- Notes:
*.md(plain text Markdown; edit with any editor) - Config:
.obsidian/(workspace + plugin settings; usually don’t touch from scripts) - Canvases:
*.canvas(JSON) - Attachments: whatever folder you chose in Obsidian settings (images/PDFs/etc.)
Find the active vault(s)
Obsidian desktop tracks vaults here (source of truth):
~/Library/Application Support/obsidian/obsidian.json
obsidian-cli resolves vaults from that file; vault name is typically the folder name (path suffix).
Fast “what vault is active / where are the notes?”
- If you’ve already set a default:
obsidian-cli print-default --path-only - Otherwise, read
~/Library/Application Support/obsidian/obsidian.jsonand use the vault entry with"open": true.
Notes
- Multiple vaults common (iCloud vs
~/Documents, work/personal, etc.). Don’t guess; read config. - Avoid writing hardcoded vault paths into scripts; prefer reading the config or using
print-default.
obsidian-cli quick start
Pick a default vault (once):
obsidian-cli set-default "<vault-folder-name>"obsidian-cli print-default/obsidian-cli print-default --path-only
Search
obsidian-cli search "query"(note names)obsidian-cli search-content "query"(inside notes; shows snippets + lines)
Create
obsidian-cli create "Folder/New note" --content "..." --open- Requires Obsidian URI handler (
obsidian://…) working (Obsidian installed). - Avoid creating notes under “hidden” dot-folders (e.g.
.something/...) via URI; Obsidian may refuse.
Move/rename (safe refactor)
obsidian-cli move "old/path/note" "new/path/note"- Updates
[[wikilinks]]and common Markdown links across the vault (this is the main win vsmv).
Delete
obsidian-cli delete "path/note"
Prefer direct edits when appropriate: open the .md file and change it; Obsidian will pick it up.
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 the-open-agent/openagent (5,710 stars, last pushed yesterday), licensed Apache-2.0. It adds 22 tokens to every session and 635 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to obsidian, differing in 2 lines, and is treated as a copy.
