bear-notes

A command-line tool for creating, reading, searching, and updating notes in Bear, a note-taking app for macOS. Some actions require Bear to be running and an access token.

In plain words
What is it for?
Use it to create notes, open notes by ID, append text, list tags, and find notes through tags.
Why use it?
It lets developers manage Bear notes from scripts and terminal workflows instead of switching to the app for every change.

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

bear-notes 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 2d 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.

Origin

This is a copy

95% identical to bear-notes — 4 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.

Bear Notes

Use grizzly to create, read, and manage notes in Bear on macOS.

Requirements

  • Bear app installed and running
  • For some operations (add-text, tags, open-note --selected), a Bear app token (stored in ~/.config/grizzly/token)

Getting a Bear Token

For operations that require a token (add-text, tags, open-note --selected), you need an authentication token:

  1. Open Bear → Help → API Token → Copy Token
  2. Save it: echo "YOUR_TOKEN" > ~/.config/grizzly/token

Common Commands

Create a note

echo "Note content here" | grizzly create --title "My Note" --tag work
grizzly create --title "Quick Note" --tag inbox < /dev/null

Open/read a note by ID

grizzly open-note --id "NOTE_ID" --enable-callback --json

Append text to a note

echo "Additional content" | grizzly add-text --id "NOTE_ID" --mode append --token-file ~/.config/grizzly/token

List all tags

grizzly tags --enable-callback --json --token-file ~/.config/grizzly/token

Search notes (via open-tag)

grizzly open-tag --name "work" --enable-callback --json

Options

Common flags:

  • --dry-run — Preview the URL without executing
  • --print-url — Show the x-callback-url
  • --enable-callback — Wait for Bear's response (needed for reading data)
  • --json — Output as JSON (when using callbacks)
  • --token-file PATH — Path to Bear API token file

Configuration

Grizzly reads config from (in priority order):

  1. CLI flags
  2. Environment variables (GRIZZLY_TOKEN_FILE, GRIZZLY_CALLBACK_URL, GRIZZLY_TIMEOUT)
  3. .grizzly.toml in current directory
  4. ~/.config/grizzly/config.toml

Example ~/.config/grizzly/config.toml:

token_file = "~/.config/grizzly/token"
callback_url = "http://127.0.0.1:42123/success"
timeout = "5s"

Notes

  • Bear must be running for commands to work
  • Note IDs are Bear's internal identifiers (visible in note info or via callbacks)
  • Use --enable-callback when you need to read data back from Bear
  • Some operations require a valid token (add-text, tags, open-note --selected)

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.
