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 | $0.00037 | $0.01206 |
| Opus 5 | $0.00018 | $0.00603 |
| Sonnet 5 | $0.00007 | $0.00241 |
| Haiku 4.5 | $0.00004 | $0.00121 |
Grade A, and why
obsidian-history-check 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.

Obsidian History Check
定位
本 skill 只读历史、版本和 diff,不恢复、不覆盖、不删除文件。
它用于在文档疑似误改或大改前查看 Obsidian 本地历史。如果 CLI 不可用,则 fallback 到 git diff/log;项目没有 git 时,提示用户使用 Obsidian GUI 文件恢复。
触发场景
- 用户问“刚才改了什么”“能不能看之前版本”。
- agent 准备大改正式文档前,需要看近期历史。
- 外部评审反馈回写本地后,需要对比修改前后。
- 文档内容疑似被误改。
何时不用
- 普通读取当前正文:直接
Read。 - 查看当前工作区修改且项目有 git:优先
git diff。 - 要恢复历史版本:本 skill 只做只读检查,恢复必须用户单独确认。
CLI Probe
优先读取 .claude/workframe-state/obsidian-cli-status.json(schema 权威定义见 skill: obsidian-doc-structure §status.json schema):
do_not_probe: true→ 永不重新 probe(不设 TTL、不做过期自判),直接按cli_available决定走 CLI 还是 fallback;重新启用 CLI 的唯一入口 = 用户手动删除该文件- 缓存缺失 → 执行非执行检测(全程不运行任何 obsidian 命令):定位命令(
Get-Command obsidian/command -v obsidian)→ 判定是否 GUI 启动器(所在目录存在Obsidian.exe/resources.pak特征文件)→ 不可用则写入 status.json(cli_available: false、do_not_probe: true、reason)并 fallback - 仅当非执行检测确认存在独立 CLI shim 时,才允许执行
obsidian version/obsidian vault info=path验证并写入commands_verified
⚠️ 未通过非执行检测时禁止执行任何
obsidian命令——在「装了 GUI 但未启用 CLI」的机器上会误启动 Obsidian 窗口。
不可用时 fallback 到 git 或 Obsidian GUI 提示。
调用前检查
执行任一 Obsidian CLI 命令前,必须依序确认:
status.json存在且do_not_probe: true且cli_available: false→ 直接 fallback,不做任何 probe。- 命令在
commands_verified数组中 → 可以使用 CLI。 - 命令不在数组中 → 直接 fallback,不尝试执行。
status.json不存在或 schema 不匹配 → 按「CLI Probe」的非执行检测流程重新检测(禁止直接执行 obsidian 命令)。
官方 CLI 命令
obsidian history path="<file>" format=json
obsidian history:list path="<file>" format=json
obsidian history:read path="<file>" version="<version>"
obsidian diff path="<file>" from="<version>"
以本机 obsidian help <command> 的参数名为准。
禁止事项
- 默认不执行
history:restore。 - 不执行
sync:restore。 - 不覆盖当前文件。
- 不把历史版本直接写回源文件。
如果用户明确要求恢复,必须先:
- 展示
diff摘要。 - 说明会覆盖哪些内容。
- 等用户明确确认。
- 优先建议另存为临时文件供人工对照,而不是直接覆盖事实源。
即使用户确认,本 skill 仍不执行 history:restore。恢复流程拆成两步:
- 本 skill 只把历史版本导出到
tmp/obsidian-history/<task-id>/restored-<version>.md。 - 用户审阅后,如确实要覆盖事实源,再单独调用
obsidian-safe-write或使用Edit执行覆盖。
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.
- 12d ago First seen · 112 lines · 37 tokens per session scan A a012f79c9da2
obsidian-history-check is a skill published in the GitHub repository ryanzhao1011/workframe (4 stars, last pushed 25d ago), licensed MIT. It adds 37 tokens to every session and 1,206 once invoked, about $0.0002 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.
