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 | $0.00000 | $0.00525 |
| Opus 5.5 | $0.00000 | $0.00210 |
| Sonnet 5.5 | $0.00000 | $0.00105 |
| Haiku 4.5 | $0.00000 | $0.00052 |
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.
How it starts
The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian
Obsidian vault = a normal folder on disk.
Use this only for explicit Obsidian vault workflows. For generic local docs, repo docs, or indexed knowledge lookup, prefer knowledge-search.
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 ships with it
2 files 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 Threat-Vector-Security/guardian-agent (13 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 525 tokens. 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.

intent-recognition
Load before you build any new kept workflow or Agent. It decides which one to build, or what to ask first. Classifies automation requests using two decisions: anchor (which primitive owns the top-level control flow — workflow-anchored, agent-anchored, needs-clarification, or out-of-scope) and embedsother (whether the…
debugging-executions
Debug failed or wrong-output workflow executions using executions tools. Load when the user reports execution failures, unexpected node output, empty parameter values after a successful run, or a node showing a red or failed expression error. Also load when a live run you started for the user fails with an error from…
planned-task-runtime
Handles system follow-up turns: planned-task-follow-up (synthesize, replan, build-workflow, checkpoint), background-task-completed, running-tasks context, and workflowbuildercreatetasks silence rules. Load whenever any of these tags appear or after calling workflowbuildercreatetasks.
suggest-automations
Offer the three most common automations for a user as a single-choice card, from your own knowledge of their team and their apps, then build the one they choose once they confirm, or offer more. The system preloads it on onboarding threads, where the opening card already asked the user about themselves. Use it on…
workflow-builder
Load before calling workflowbuilderbuildworkflow. Use for single-workflow work: new one-off workflows, existing-workflow edits, verification repairs, and workflow-local data tables. For any other new workflow, load intent-recognition first when it is listed. Write or edit a workspace source file, run workflow-sdk…
nx-plugin-for-aws
Scaffold and build cloud-native applications on AWS using @aws/nx-plugin generators. Use when the user wants to create workspaces, generate projects, or scaffold infrastructure with the Nx Plugin for AWS.
