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 | $0.00047 | $0.00380 |
| Opus 5.5 | $0.00019 | $0.00152 |
| Sonnet 5.5 | $0.00009 | $0.00076 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
siyuan-mcp-tag-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 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.

What it actually says
Manage SiYuan Tags and Flashcards with MCP
Create tags by writing #tag# into Markdown. Create flashcards with the flashcard action so both riff registration and block metadata remain consistent.
block(action="append", parentID="<doc-id>", dataType="markdown", data="#project# #project/phase1#")
tag(action="list", keyword="project")
tag(action="rename", oldLabel="old-tag", newLabel="new-tag")
Flashcard workflow
Create or identify a heading block, discover the target deck, then register the block as a card:
block(action="append", parentID="<doc-id>", dataType="markdown", data="## What is spaced repetition?\n\nReview just before forgetting.")
flashcard(action="get_decks")
flashcard(action="create_card", deckID="<deck-id>", blockIDs=["<heading-block-id>"])
flashcard(action="list_cards", scope="deck", deckID="<deck-id>", filter="due")
flashcard(action="review_card", deckID="<deck-id>", cardID="<card-id>", rating=3)
Ratings are 1 through 4, with larger values representing easier recall. Do not imitate flashcard creation with block attributes alone. Before removing a tag or card, show the exact label, deck, and block IDs and obtain approval. Newly written tags and headings may need a short indexing delay before discovery actions show them.
What ships with it
1 file 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.
