Introducing Breadcrumb: A Total Recall & Context Engine for your Mac

Breadcrumb is an AI-powered plugin designed specifically for developers. It acts as a comprehensive record of your Mac's activity, serving as a sophisticated context manager that allows you to dictate rules, shortcuts, and scopes for your AI assistants.

📂 Managing Context via "Scopes"

A scope is essentially a folder tied to a specific set of behavioral rules. When you are working within a scoped directory, the associated rules are applied to your AI automatically.

Scope PathRule CountNote Count
/ (Global)2288
/acme2870
/myapp91269
/personal04

Compatible with: claude, chatgpt, cursor, and opencode.


🖥️ Visual Memory & Screen Awareness

Your AI no longer guesses; it remembers exactly what appeared on your screen. For instance, if you were managing local snapshots, the AI knows the exact state of your system:

System Context Example: To view your current snapshots, you can execute: tmutil listlocalsnapshots /

To wipe them clean, use: tmutil deletelocalsnapshots /

Note: These are currently consuming 197 GB197\text{ GB}197 GB of disk space.

📅 Chronological Awareness

Breadcrumb tracks your day so your AI understands your workflow.

Standup Summary (09:32):

  • Priority: Ella needs a walkthrough of the retailer bug as soon as possible.

The most intense focus period was the 3h 40m spent on the landing page during the afternoon.


🔄 Seamless Session Continuity

When a long conversation becomes too bloated and the AI gets overwhelmed, Breadcrumb allows a new chat to pick up exactly where the previous one stalled.

  • Session: Landing page footer →\rightarrow→ 15:19 · 1h 42m · 38 turns
    • (a) Continue →\rightarrow→ (a?) More info
  • Session: Loyalty dashboard totals →\rightarrow→ Yesterday · 3h 10m · 64 turns
    • (b) Continue →\rightarrow→ (b?) More info
  • Session: Speaker elimination →\rightarrow→ Tuesday · 55m · 19 turns
    • (c) Continue →\rightarrow→ (c?) More info
  • (s) View all other sessions

🛠️ Rules and Shortcuts

Dynamic Rule Creation

If you correct your AI, Breadcrumb suggests turning that correction into a permanent rule.

Proposed Rule: Never push main “Never push main, merge, publish, or release without my explicit word.”

One-Word Shortcuts

Any repetitive workflow or complex instruction can be condensed into a single keyword.

  • Example Workflow:
    • 15m →\rightarrow→ Standup
    • 4h 10m →\rightarrow→ Loyalty dashboard
    • 4h 20m →\rightarrow→ BUG-292
    • Total: 8h 45m
  • Action: Would you like to make this a one-word shortcut?

🔒 Privacy & Local Architecture

Breadcrumb operates on the principle that Privacy=Local Processing+Encryption\text{Privacy} = \text{Local Processing} + \text{Encryption}Privacy=Local Processing+Encryption.

  • Local Intelligence: Transcription, speaker identification, and daily organization are handled by models running directly on your Mac.
  • Zero Data Transfer: No data is sent to the developers. The only communication is a daily update check that contains no identifying information.
  • No Voiceprints: Speaker naming is derived from on-screen visual cues, not biometric voice data.
  • Granular Control: You can explicitly exclude specific apps, websites, or sensitive phrases from being recorded.
