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 | $0.00042 | $0.01004 |
| Opus 5 | $0.00021 | $0.00502 |
| Sonnet 5 | $0.00008 | $0.00201 |
| Haiku 4.5 | $0.00004 | $0.00100 |
Grade A, and why
siyuan-sisyphus-system-cli 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 12d 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.
This is a copy
89% identical to siyuan-mcp-system-safety — 42 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SiYuan System and Safety with the CLI
Start with a connectivity check and inspect live help before unfamiliar actions.
siyuan-sisyphus system get-version --json
siyuan-sisyphus system get-current-time --json
siyuan-sisyphus notebook get-permissions --json
Notebook permissions are rwd, rw, r, and none. Missing content can mean permission filtering rather than absence. Record the current value before proposing a permission change.
Confirmation boundary
Obtain explicit approval before notebook/document/block deletion or move, bulk replacement, asset upload or deletion, local-path export, tag/card removal, permission changes, and workspace path disclosure. State the exact target and consequence. A prior request to inspect or diagnose is not approval to mutate.
siyuan-sisyphus system conf --mode 'summary' --json
siyuan-sisyphus system network --json
siyuan-sisyphus system notify --msg 'Task complete' --level 'info' --timeout '5000' --json
siyuan-sisyphus extension list --no-refresh --json
Extension trust and lifecycle verification
Treat an extension package as executable third-party code. Keep these checks separate; passing one does not prove the next one:
- Static package check: inspect the package metadata and required files, exact
minAppVersion,backends,kernels, andfrontendsvalues, then review the source, entrypoint, handlers, and cleanup paths. A package validator can catch malformed or incompatible files, but it cannot prove that SiYuan loaded the package. - Actual loading: inspect the current runtime inventory and the user-visible enabled state. A package being present, discoverable, or statically valid is not evidence that its
onloador kernel entrypoint ran. - Registration and unregistration: for an approved live check, verify the lifecycle-owned surface after enablement (for example a frontend Agent action or plugin MCP tool), then disable/unload it and verify the same name is gone. Confirm that DOM nodes, listeners, timers, RPC methods, and MCP tools are cleaned up; the official
siyuan-sisyphus help extension listbridge only reports tools exposed by SiYuan's/mcpregistry and is not a substitute for frontend UI evidence. - Reload and functional readback: use the supported reload path, then repeat discovery and one harmless surface-specific interaction. Check that the new behavior works once, old registrations are absent, and no duplicate handlers remain. Do not treat a refreshed tool list as proof that a plugin UI or desktop-only code path works.
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-system-cli is a skill published in the GitHub repository yangtaihong59/siyuan-plugins-mcp-sisyphus (104 stars, last pushed 2d ago), licensed MIT. It adds 42 tokens to every session and 1,004 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to siyuan-mcp-system-safety, differing in 42 lines, and is treated as a copy.
