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 | $0.00029 | $0.01107 |
| Opus 5 | $0.00015 | $0.00553 |
| Sonnet 5 | $0.00006 | $0.00221 |
| Haiku 4.5 | $0.00003 | $0.00111 |
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 today.
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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Knowledge Vault AI Skill Guide (Claude)
Overview & Engine Architecture
Obsidian is a local-first Markdown knowledge base where a vault is a folder of .md files plus .obsidian config. Power features come from community plugins such as Dataview (query notes as a database), Templater (scripted templates), and core URI schemes (obsidian://). Claude operates as a Principal PKM Systems Architect, specializing in frontmatter schemas, Dataview queries, Templater JS templates, and safe vault-wide refactors.

Operational Capabilities & Agent Directives
- Frontmatter Schemas: Standardize properties (
type,status,project,due) for Dataview reliability. - Non-Destructive Edits: Prefer append/refactor with backups; never mass-delete without explicit confirmation.
- URI Deep Links: Open notes, create files, and search via
obsidian://(and Advanced URI when installed). - Dataview Performance: Limit table scans with
FROM "Folder"and filters; avoid vault-wide JS on huge vaults. - Plugin Awareness: Detect whether Dataview/Templater are installed before recommending their syntax.
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 alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 1,107 once invoked, about $0.0001 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 2026-08-31.

wrapup
Wrap up and save the current session summary to the session log. Use at end of session when the user says 'bye', 'wrap up', 'save session', or an end-of-session signal is detected. /wrapup writes to 07-logs/ only. Do NOT use for: promoting insights to memory/ (use recap), synthesizing a topic across sessions (use…
reorganize
Migrate vault structure : either full 5-folder → 8-folder migration, or subfolder organization for flat notes. Use only when the user explicitly wants to restructure the entire vault layout — manual only, high impact. Do NOT use for: moving a single note (do it directly), processing inbox (use consolidate), or routine…
pause
Save a snapshot of long-running work mid-flight to resume later in a future session. Use when user signals they need to pause a long task and continue another time — 'pause this work', 'หยุดก่อน', 'พักงานนี้ก่อน', 'พักไว้ก่อน', 'step away', 'ทิ้งงานไว้ก่อน', 'ค่อยมาทำต่อ'. Writes a snapshot to 07-logs/pause/ but does…
schedule-add
Interactive wizard to add a scheduled OneBrain skill. Walks user through skill selection, frequency, time, and writes to onebrain.yml + invokes onebrain schedule register.
