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 | $0.00052 | $0.01230 |
| Opus 5 | $0.00026 | $0.00615 |
| Sonnet 5 | $0.00010 | $0.00246 |
| Haiku 4.5 | $0.00005 | $0.00123 |
Grade A, and why
siyuan-sisyphus 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 yesterday.
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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SiYuan Sisyphus with the CLI
Use the narrowest scenario skill that matches the task. For unfamiliar fields, inspect siyuan-sisyphus list and siyuan-sisyphus help <tool> <action> before calling an action; live action help is the parameter-level source of truth.
Scenario routing

|---|---|
| Browse notebooks, documents, paths, IDs, and blocks | siyuan-sisyphus-browse-read |
| Create documents or edit blocks | siyuan-sisyphus-create-edit |
| Fulltext, SQL, backlinks, references, and replacement | siyuan-sisyphus-search-query |
| Attribute views, columns, rows, and cells | siyuan-sisyphus-database |
| Assets, extraction, and exports | siyuan-sisyphus-file-export |
| Staged Markdown/database import and migration | siyuan-sisyphus-import-migration |
| Semantic SVG and visual asset embedding | siyuan-sisyphus-visual-assets |
| Tags, decks, cards, and review | siyuan-sisyphus-tag-flashcard |
| Timeline nodes, snapshot comparison, and rollback | siyuan-sisyphus-timeline |
| Permissions, system information, and dangerous operations | siyuan-sisyphus-system-cli |
| Extension package trust, compatibility, and lifecycle verification | siyuan-sisyphus-system-cli |
| Rich Markdown, math, diagrams, and SiYuan markup | siyuan-markup-guide |
Tool choice
Prefer fs for ordinary human-readable workspace paths. Use document or block for IDs, storage paths, metadata, or block-granular changes. Use av for real databases rather than Markdown tables. Use timeline for named snapshots, document diffs, and rollback. Low-complexity feedback and mascot actions need no separate scenario skill.
The CLI, a raw MCP payload, and an Agent-generated call are invocation forms, not proof that Sisyphus strict-write handling ran. For a protected mutation, follow the selected runtime's current help and returned safety fields. The documented preflight, single-attempt transport, idempotency, and readback guarantees apply only when the call is routed through the active Sisyphus write coordinator with strict mode enabled. Do not infer kernel-level compare-and-swap or parity with native SiYuan and third-party calls.
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.

siyuan-sisyphus is a skill published in the GitHub repository yangtaihong59/siyuan-plugins-mcp-sisyphus (104 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 1,230 once invoked, about $0.0003 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.
