jot

A single Obsidian note tool that sorts a short capture into today’s daily note or creates a longer note in the configured vault folder.

In plain words
What is it for?
Use it to append timestamped journal entries, logs, tags, or quick ideas, or to create titled notes with longer content.
Why use it?
It removes the need to decide which note workflow and command to use. If the Obsidian setup is missing, it tells you how to initialize it.

Token cost

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.

Security

Grade A, and why

jot 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.

jot — Capture or Note

Single triage skill. Decide the mode, then run the obsidian CLI directly — no sub-agent. Before any CLI call, invoke the obsidian:obsidian-cli skill to load exact syntax — never run obsidian help/--help to discover it. If .obsidian.yaml is missing, tell the user to run /obw:init and stop.

Mode selection

Inspect the user's input:

  • cap mode — short text (one line / a sentence), #tag tokens, no explicit title, journaling/log verbs. Goes to today's daily note.
  • note mode — explicit title, multi-line body, "create a note on X", document-shaped content. Goes to a vault folder (per .obsidian.yaml note config).
  • ambiguous — call AskUserQuestion with two options: "Quick capture (daily note)" and "New long-form note".

cap mode

Append a timestamped bullet to today's daily note. Nothing more. Daily note folder / filename / template are owned by Obsidian's Daily Notes core plugin.

  1. If body is empty, prompt for content.
  2. Compose bullet: - HH:MM — <body> (any #tag tokens stay inline — Obsidian indexes them automatically).
  3. Append the bullet to today's daily note via daily:append (creates the note if missing).
  4. Confirm with the appended line. Return [[<daily-note-basename>]].

Example: 記一下 #worklog 完成了 API-first 架構 draft- 14:32 — 完成了 API-first 架構 draft #worklog

note mode

Config (.obsidian.yaml):

vault: <VAULT_NAME>
note:
  default_folder: Inbox
  filename_strategy: title     # title | slug | timestamp-title
  1. Parse input:

    • title — required, first non-flag text.
    • --folder <path> — override default folder (vault-relative, reject leading / or ..).
    • --tag <tag> — repeatable, adds to frontmatter.
    • Trailing text after flags — optional initial body.
  2. Compute filename by kebab-casing the title (lowercase, whitespace/punctuation → -, collapse repeats). Keep Unicode characters intact.

    • title<kebab>.md
    • slug<kebab>-YYYYMMDD.md
    • timestamp-titleYYYYMMDD-<kebab>.md

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.

jot is a skill published in the GitHub repository musingfox/cc-plugins (2 stars, last pushed 2d ago), licensed MIT. It adds 84 tokens to every session and 848 once invoked, about $0.0004 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.
