What it does

Siyuan MCP Tag Flashcard is an agent skill from yangtaihong59/siyuan-plugins-mcp-sisyphus. MCP playbook for SiYuan tags and flashcards. Use for inline tags, tag discovery and rename, deck discovery, card creation, due/new review, and safe removal.

It sits in Education, covering Study guides and flashcards and MCP servers. It works with Model Context Protocol. The repository describes itself as: 一个用于连接Agent与Siyuan的工具. The licence is MIT.

When your agent uses it

  • Tag discovery and rename
  • Tasks that involve Study guides and flashcards
  • Tasks that involve MCP servers

Example prompts

  • “/siyuan-mcp-tag-flashcard”

What it can do on your machine

Read from SKILL.md and the folder at commit d2ad534. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Siyuan MCP Tag Flashcard loads about 393 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 101 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~393

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

text
block(action="append", parentID="<doc-id>", dataType="markdown", data="#project# #project/phase1#")
text
tag(action="list", keyword="project")
text
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:

text
block(action="append", parentID="<doc-id>", dataType="markdown", data="## What is spaced repetition?\n\nReview just before forgetting.")
text
flashcard(action="get_decks")
text
flashcard(action="create_card", deckID="<deck-id>", blockIDs=["<heading-block-id>"])
text
flashcard(action="list_cards", scope="deck", deckID="<deck-id>", filter="due")
text
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.
