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 | $0.00090 | $0.00652 |
| Opus 5 | $0.00045 | $0.00326 |
| Sonnet 5 | $0.00018 | $0.00130 |
| Haiku 4.5 | $0.00009 | $0.00065 |
Grade A, and why
codian 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 5d 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
Codian Memory
把 Obsidian vault 作为长期记忆，支持读、写、摘要、分类。
脚本路径
Skill 自带的脚本在 <skill_dir>/scripts/obsidian_memory.py。
配置
首次使用 — 运行以下命令，输入你的 Obsidian vault 路径：
python3 <skill_dir>/scripts/obsidian_memory.py init
或者设置环境变量 OBSIDIAN_VAULT=/path/to/vault。
触发词
读取记忆/我之前做过什么把这个记住/以后记住/记录到更新会话总结/同步 Obsidian初始化 Codian
Workflow
1. 读取记忆
python3 <skill_dir>/scripts/obsidian_memory.py read --query "<关键词>" --logs-limit 3
完整读取（仅在用户明确要求时）：
python3 <skill_dir>/scripts/obsidian_memory.py read --full
2. 写入记忆
写入前先确认内容：
python3 <skill_dir>/scripts/obsidian_memory.py append \
--summary "<总结内容>" \
--tags "#memory" \
--source "当前 Hermes 会话" \
--keywords "key1, key2"
3. 生成项目摘要
python3 <skill_dir>/scripts/obsidian_memory.py project-summary --max-logs 20
4. 生成分类记忆
python3 <skill_dir>/scripts/obsidian_memory.py memory-categories --max-logs 80

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.

codian is a skill published in the GitHub repository zixiaomiao/Codian (5 stars, last pushed 3mo ago), licensed MIT. It adds 90 tokens to every session and 652 once invoked, about $0.0005 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 2026-08-31.
