For every complex task, create THREE files:

task_plan.md → Track phases and progress notes.md → Store research and findings [deliverable].md → Final output

The Loop

1. Create task_plan.md with goal and phases
2. Research → save to notes.md → update task_plan.md
3. Read notes.md → create deliverable → update task_plan.md
4. Deliver final output

Key insight: By reading task_plan.md before each decision, goals stay in the attention window. This is how Manus handles ~50 tool calls without losing track.

If you find yourself writing a prompt for something repetitively and instructions can be static/precise, it's a good idea to make a custom command. You can tell Claude to make custom commands. It knows how (or it will search the web and figure it out via claude-code-guide.md) and then it will make it for you.

The Explore agent is a read-only file search specialist. It can use Glob, Grep, Read, and limited Bash commands to navigate codebases but is strictly prohibited from creating or modifying files.

You will notice how thorough the prompt is in terms of specifying when to use what tool call. Well, most people underestimate how hard it's to make tool calling work accurately.

Context engineering is about answering "what configuration of context is most likely to generate our model's desired behavior?"

Extracting Claude’s soul.

Antigravity is Google’s new agentic code editor. In this article, we demonstrate how an indirect prompt injection can manipulate Gemini to invoke a malicious browser subagent in order to steal credentials and sensitive code from a user’s IDE.

Google’s approach is to include a disclaimer about the existing risks, which we address later in the article.

Fascinating prompt engineering and injection (harmless).
