I'm posting Claude Certified Architect exam notes in public.

Domain 2 so far:
• 2.1 Tool Interface Design
• 2.2 Structured Error Responses
• 2.3 Tool Distribution & Tool Choice
• 2.4 MCP Server Integration

If you are sitting the exam, or wiring Claude to real tools, follow along.

I post the trap, the rule, and the config — not a syllabus dump.

Full 2.4 article is up. Next posts break out the bits that show up on the exam.

The fastest way to blow your context window:

“Let me read the entire codebase first.”

Hundreds of files. Most of them irrelevant.

The exam wants this instead:

1. Grep for the function, class, error, or feature
2. Read only the relevant files
3. Follow imports and exports
4. Grep again for consumers and wrappers

🎯 Discover first. Read second.

Expand only when you have a reason.

Every file in your context should earn its seat.

@IndianTechGuide @grok what’s the limit ? Same branch atm & other branch atm ?

[X Sparkler ✨ @X_Sparkler]

Don’t **Read an entire file and Write it back**
just to rename a function.

**Edit** is the default for targeted changes.

Give Claude the **old text** and the **new text**.
It changes only that specific part.

If Edit says the match isn’t unique:

1. **Widen the anchor** → add more surrounding text
2. Use **`replace_all: true`** → if every match should change
3. **Read + Write** → only if needed

⚠️ A non-unique Edit is not a failed Edit.

Your anchor was just too short.

🎯 **Escalation:**

**Edit → Widen the anchor → `replace_all` → Read + Write**

@trq212 @grok summary?

[X Sparkler ✨ @X_Sparkler]

@arthamegayasa @bot @grok @grok ??

[X Sparkler ✨ @X_Sparkler]

@arthamegayasa @bot @grok @grok free trail not enough for 15 mins ?

[X Sparkler ✨ @X_Sparkler]

@TJeparskis Haha let’s see 👀😅

[X Sparkler ✨ @X_Sparkler]

Grok Bot is now more widely available 🚀

[Grok Bot @bot]

We're making Grok Bot more widely available.

All SuperGrok Plus, Cursor Pro+, and Cursor Teams subscribers now have access.

We're also offering a free trial with limited usage for all other users.

[X Sparkler ✨ @X_Sparkler]

Will try updating & let’s see 👀

[OpenCode @opencode]

if you've been using Ox Alpha and dealing with network errors, upgrade to OpenCode 1.18.21

it will retry unknown stops automatically and should make things more usable

now stop slacking and hit that 100T number

@debs_obrien 😅🫡🫡 nice

[X Sparkler ✨ @X_Sparkler]
