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 | $0.00033 | $0.01355 |
| Opus 5 | $0.00016 | $0.00678 |
| Sonnet 5 | $0.00007 | $0.00271 |
| Haiku 4.5 | $0.00003 | $0.00136 |
Grade A, and why
flashcard 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 10d 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 — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flashcard Skill
This skill enables you to create and edit flashcards for spaced repetition learning. Flashcards are stored in markdown files with specific formatting rules.
Flashcard Structure
Flashcards can be defined in two styles:
Single-Line Style
A single-line flashcard uses :: or ::: as separators:
Question :: Answer— Standard flashcard (question on front)Question ::: Answer— Reversed flashcard (both sides can be swapped)
Examples:
What is the capital of France? :: Paris
The process of photosynthesis ::: Plants converting light energy into chemical energy
Multiple-Line Style
A multiple-line flashcard uses ? or ?? as separators:
Standard flashcard (?):
What are the three types of rock?
?
Igneous, sedimentary, and metamorphic
Reversed flashcard (??):
The Pythagorean theorem
??
a² + b² = c² in a right triangle
Desk Organization
Flashcards must always belong to a desk, indicated by tags prefixed with #flashcards:
Desk Tags
#flashcards/Math— All math flashcards#flashcards/Math/Addition— Specific topic within math#flashcards/History/WorldWar2— Multi-level desk hierarchy
Example:
#flashcards/Math/Addition
What is 2 + 2? :: 4
What is 15 + 27? :: 42
#flashcards/Math/Subtraction
What is 10 - 3? :: 7
What is 50 - 18? :: 32
Rules for Desk Tags
- Every flashcard must be below a desk tag (prefixed with
#flashcards) - Desk tags can have hierarchical paths using
/separator - All flashcards between one desk tag and the next (or end of file) belong to that desk
Sequential Review with @start/@end Markers
For flashcards that need to be reviewed in a specific order, use @start and @end markers:
Syntax
@start <Description>
Question 1 :: Answer 1
Question 2 :: Answer 2
Question 3 :: Answer 3
@end
- The
@startmarker must include a description - Flashcards between
@startand@endare always reviewed in sequence - Sequential groups must still be under a desk tag
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.

flashcard is a skill published in the GitHub repository googlicius/obsidian-steward (86 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 1,355 once invoked, about $0.0002 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 2026-08-30.
