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 | $0.00046 | $0.01014 |
| Opus 5 | $0.00023 | $0.00507 |
| Sonnet 5 | $0.00009 | $0.00203 |
| Haiku 4.5 | $0.00005 | $0.00101 |
Grade A, and why
obsidian-markdown 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 6d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CIEL ADAPTATION: Obsidian Flavored Markdown
Create and edit valid Obsidian Flavored Markdown, which extends CommonMark and GFM with wikilinks, embeds, callouts, properties, comments, and math/diagram syntax. Standard Markdown (headings, bold, lists, tables, code blocks) is assumed knowledge; this skill covers only Obsidian-specific extensions.
Authoring Workflow
- Frontmatter: Add properties (title, tags, aliases) at the top of the file
- Content: Use standard Markdown for structure plus Obsidian-specific syntax below
- Links:
[[wikilinks]]for in-vault notes (auto-tracks renames);[text](url)for external URLs only - Embeds:
![[embed]]for inline content from other notes, images, or PDFs - Callouts:
> [!type]for highlighted information - Verify: Confirm the note renders correctly in Obsidian's reading view
Internal Links (Wikilinks)
[[Note Name]]— link to note[[Note Name|Display Text]]— custom display text[[Note Name#Heading]]— link to heading[[Note Name#^block-id]]— link to block[[#Heading in same note]]— same-note heading link- Define block IDs by appending
^block-idto a paragraph; for lists/quotes place the ID on a separate line after the block
Embeds
![[Note Name]]— embed full note![[Note Name#Heading]]— embed section![[image.png]]/![[image.png|300]]— image, optional width![[document.pdf#page=3]]— PDF page
Callouts
> [!note]— basic callout> [!warning] Custom Title— callout with custom title> [!faq]- Collapsed by default— foldable (-collapsed,+expanded)- Types:
note,tip,warning,info,example,quote,bug,danger,success,failure,question,abstract,todo
Properties (Frontmatter)
tags— searchable labels (also settable inline via#tag/#nested/tag)aliases— alternative note names for link suggestionscssclasses— CSS classes for styling- Tag rules: letters, numbers (not first char), underscores, hyphens, forward slashes
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.
