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.

What it costs to keep this loaded
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 | $0.00036 | $0.00300 |
| Opus 5 | $0.00018 | $0.00150 |
| Sonnet 5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
obsidian-ref 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 11d 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.
What it actually says
Obsidian Reference Skill
This skill provides comprehensive technical references and standards for the Obsidian ecosystem.
Purpose
To provide a central source of truth for API usage, file formats, and design standards.
Scope
This skill covers:
manifest.jsonrequirements and validation- Obsidian API details and documentation
- Obsidian-specific file formats (Markdown, Properties, Canvas)
- UI text conventions and UX patterns
- Mobile and platform compatibility
Core Rules
- API Authority: The
obsidian.d.tsfile in the reference materials is the authoritative source for API details. - Terminology Consistency: Follow the "properties" and "Markdown" naming conventions strictly.
- Mobile First: Consider mobile compatibility for all UI and file-handling features.

What ships with it
8 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.
