Prompting and Task Execution — study note

Prompting and Task Execution — study note

Domain 1 of the Claude Certified Associate – Foundations exam (about 14% of scored items). Its four objectives ask you to write effective prompts, decompose complex requests, iterate toward better output, and adapt your strategy to the kind of task. This note summarizes what each topic teaches and the Anthropic pages behind it.

The brief: what a good prompt contains

Anthropic suggests picturing Claude as a newly hired contractor: capable, but with no context about you, your task or your organization. The prompt is the brief that supplies that context.

Part of the briefWhat it answersExample
Task and formWhat, and in what shape?Five bullet points, under 150 words
AudienceWho reads it?All staff
ReasonWhy does it matter?Read aloud, so avoid ellipses
ExamplesWhat does good look like?Three approved emails, marked

Test it with the golden rule: show the prompt to a colleague with minimal context. If they would be confused, Claude will be too.

Structuring bigger requests

  • Numbered steps when the order or completeness of the steps matters.
  • Tagged parts when a prompt mixes instructions, background, examples and pasted material: wrap each kind of content in its own tag, typed as plain text.
  • Draft → review against criteria → refine when you need to inspect intermediate output before moving on. (Claude handles most multistep reasoning internally, so stage only when you need the checkpoint.)

Iterating toward better output

SituationWhat to do
You cannot tell if a new version is betterAgree success criteria first, and a way to check them
The answer is close but not rightGive specific feedback in the same chat
You keep writing “don’t…” rulesSay what to do instead
The answer stops partwayAsk it to continue in the same chat; in a new chat, give Claude the previous prompt and response first
Content is fine but it is too slow or costlyA different model can sometimes improve speed and cost more easily than rewording

Choosing a strategy by task type

Task typeStrategy
Quick current factWeb search
Hard reasoning, no fresh dataReasoning without web search
Cited report from many sourcesResearch, ideally with extended thinking so Claude plans first
DraftingAudience, requirements and key points; send the whole text
AnalysisQuestion and focus areas up front; all the data in one message
BrainstormingAsk explicitly for range and ambition

What you can use depends on your plan and your organization’s settings; research needs web search turned on.

Common traps

  • Rewording a prompt with no agreed criteria, so no one can tell which version is better.
  • Sending material in pieces, so each reply covers only part of it.
  • Relying on Claude to infer that you want bold ideas, a particular reader or a particular format.
  • Treating technical requests (a spreadsheet formula, a setup checklist) as exempt from the brief: they need the inputs, the result and the form just as much.
