Prompt Analysis

✅ Successful Prompt Patterns

• Average body length: ~175 words
• 26% of merged PR bodies reference specific file paths/types (vs 13% for closed)
• Common verbs: fix, resolve, add, pin, include

1. PR Resolve Copilot detection alias on Luna-only catalogs and add larger-model fallbacks #74957: Resolve Copilot detection alias on Luna-only catalogs... → Merged
2. PR Pin DIFC and CLI proxy images to the gateway digest #74950: Pin DIFC and CLI proxy images to the gateway digest → Merged
3. PR Include detection reporting permissions in conclusion App tokens #74949: Include detection reporting permissions in conclusion App tokens → Merged

❌ Unsuccessful Prompt Patterns

• Average body length: ~145 words
• Fewer file references; investigative or verification-only tasks
• Issues: no concrete code change requested, [WIP] broad refactors

1. PR [WIP] Refactor functions exceeding length limits in various packages #74913: [WIP] Refactor functions exceeding length limits in various packages → Closed
2. PR Investigate clustered smoke-engine failures #74790: Investigate clustered smoke-engine failures → Closed
3. PR Verify reported command-injection findings are already mitigated #74788: Verify reported command-injection findings are already mitigated → Closed

Key Insights

• Specific targets win: merged prompts reference files twice as often as closed ones.
• Investigate/verify prompts often close without code change; broad refactors (77%) lag other categories.
• Context helps: merged bodies are slightly longer (175 vs 145 words).

Recommendations

1. DO: Name specific files/functions and the expected change.
2. DO: Include context such as error messages or findings (bug fixes: 90%).
3. AVOID: Broad multi-package refactors and investigate-only tasks; split into scoped changes.
