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 | $0.00081 | $0.00841 |
| Opus 5.5 | $0.00032 | $0.00336 |
| Sonnet 5.5 | $0.00016 | $0.00168 |
| Haiku 4.5 | $0.00008 | $0.00084 |
Grade A, and why
init-vault 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.

Initialize Obsidian Vault Context (大脑全景图初始化)
This skill establishes a structured context map for Obsidian second brain vaults using the PARA method (Projects, Areas, Resources, Archives). It creates CLAUDE.md files throughout the vault that serve as AI-readable navigation and context for knowledge work.
Quick Start
/init-vault # Full vault incremental update
/init-vault Areas/AI # Update specific module only
Core Principles
- Safety First: Read-only mode. Never modify original notes.
- Registry Pattern: Maintains root
CLAUDE.mdas vault routing table. - Dispatch Architecture: Recursively deploys
init-engineeragents to active PARA modules.
Workflow
Stage A: Terrain Scanning (Inventory)
Scan top-level directories (Projects, Areas, Resources, Archives):
- Identify all sub-modules (second-level folders)
- Check
.claude/index.jsonor modification time for incremental updates - Skip unchanged modules to optimize performance
Stage B: Distributed Execution (Iterative Dispatch)
Critical: Do not pass all paths to a single agent (causes tool call limits).
Loop through target modules and dispatch init-engineer in batches:
For each module (or batch of 3-5 modules):
- Call init-engineer agent with:
- module_path: <current_path>
- mode: "adaptive"
- Handle errors: log and continue, don't halt entire process
- Collect status reports from each agent
See references/init-engineer-spec.md for the agent specification.
Stage C: Aggregate Index
Update root CLAUDE.md with:
- Mermaid structure diagram: PARA topology visualization
- Active context links: List of just-updated module
CLAUDE.mdfiles - Global changelog: Summary of this initialization run
Safety & Boundaries
Read-Only Principle
- Read
.md,.canvas, and other text files only - Absolutely forbidden: Modify or delete any original notes
What ships with it
3 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.
- 1mo ago First seen · 101 lines · 81 tokens per session scan A 6e195da29600
init-vault is a skill published in the GitHub repository air-yan/obsidian_second_brain_skills (2 stars, last pushed 8mo ago), licensed MIT. It adds 81 tokens to every session and 841 once invoked, about $0.0003 per session on Opus 5.5. 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.
