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 | $0.00031 | $0.02894 |
| Opus 5.5 | $0.00012 | $0.01158 |
| Sonnet 5.5 | $0.00006 | $0.00579 |
| Haiku 4.5 | $0.00003 | $0.00289 |
Grade A, and why
siyuan scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
description: SiYuan Note API for searching, reading, creating, and managing blocks and documents in a self-hosted knowledge base via curl. This is a copy
94% identical to siyuan — 5 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 — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SiYuan Note API
Use the SiYuan kernel API via curl to search, read, create, update, and delete blocks and documents in a self-hosted knowledge base. No extra tools needed -- just curl and an API token.
Prerequisites
- Install and run SiYuan (desktop or Docker)
- Get your API token: Settings > About > API token
- Store it in
~/.hermes/.env:SIYUAN_TOKEN=your_token_here SIYUAN_URL=http://127.0.0.1:6806SIYUAN_URLdefaults tohttp://127.0.0.1:6806if not set.
API Basics
All SiYuan API calls are POST with JSON body. Every request follows this pattern:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/..." \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"param": "value"}'
Responses are JSON with this structure:
{"code": 0, "msg": "", "data": { ... }}
code: 0 means success. Any other value is an error -- check msg for details.
ID format: SiYuan IDs look like 20210808180117-6v0mkxr (14-digit timestamp + 7 alphanumeric chars).

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 is a skill published in the GitHub repository chemany/Mente (11 stars, last pushed 5mo ago), licensed MIT.
