Claude prompt for code generation: Error Taxonomy (2026 Playbook)
Claude · Code Generation · 2026 Playbook
You are a systems thinker using Claude for code generation, specifically error taxonomy.
Job: codes humans can use.
Audience: api design. Constraint: retry guidance.
Working style: current and tactical. Optimize for what works now, including evaluation loops.
Process:
1. Restate the brief in one sentence and list missing facts as questions.
2. Draft the artifact.
3. Stress-test it against the constraint.
4. Return a final version plus 3 numbered improvements.
Output contract: use headings, short paragraphs, and concrete examples. No filler. No invented statistics.
If information is missing, make the smallest reasonable assumption and label it.Use this Claude code generation template when api design need error taxonomy with the rule: retry guidance. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The 2026 playbook version uses current and tactical language and targets what works now, including evaluation loops.
When to use this prompt
Claude shines at code generation work when you state the observable outcome: codes humans can use. The 2026 Playbook framing keeps what works now, including evaluation loops visible while you edit. Bookmark this page if you run error taxonomy weekly.
Why this prompt works
- Centers codes humans can use so success is observable.
- Repeats the hard constraint: retry guidance.
- Asks for a self-check pass, which cuts hallucinated details.
- Locks the audience (api design) before style so tone stays honest.
- Forces an output contract: headings, examples, and a final version.
How to use it in Claude
Ask for a shorter version after the long one; compression reveals weak claims. Functions, refactors, tests, and architecture sketches. Keep that context in the thread when you iterate. Redact client names; keep structure. Slug error-taxonomy-playbook is your canonical URL for this brief. This 2026 Playbook path is for api design who care about codes humans can use. Name the success metric aloud: codes humans can use. If the draft cannot pass it, do not polish prose yet.
Run a constrained version and a wild version of error taxonomy. Keep structure from one and energy from the other. For error taxonomy in code generation, the failure mode is usually missing constraint. This prompt blocks that by design — especially "retry guidance". Expect two minutes customizing and two minutes editing for 2026 Playbook output. Anthropic models still need your facts for error taxonomy; they cannot invent metrics or brand rules. developers teams bookmark slug error-taxonomy-playbook when what works now, including evaluation loops matters.
Step-by-step
- Open Claude and paste the prompt block unchanged.
- Replace placeholders with your project facts (api design, offer, timeline).
- Confirm the constraint is still visible: retry guidance.
- Because this is the 2026 Playbook variant, prioritize what works now, including evaluation loops over length.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Error Taxonomy, 3 short sections, bullet list of recommendations, closing line that states retry guidance. Facts you supply appear; nothing invented.
Common mistakes
- Skipping the audience (api design) and hoping Claude infers it.
- Asking for error taxonomy plus three other jobs in one message.
- Pasting confidential data instead of redacted placeholders.
Expert notes
Anthropic users working on error taxonomy in code generation should treat "retry guidance" as non-negotiable. Functions, refactors, tests, and architecture sketches. When api design run the 2026 Playbook variant, they usually care about what works now, including evaluation loops more than length.
If text output feels generic, re-paste retry guidance as the first follow-up message — do not rewrite the whole prompt.
