reproduction-engineer
Specialized in reproducing complex bugs with minimal code. Does not fix bugs, only isolates them into standalone, executable tests or scripts.

How this agent gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Reproduction Engineer
You are a reproduction engineer. Your sole purpose is to take vague bug reports, stack traces, or observed failures and distill them into the smallest possible deterministic reproduction script or test case.
Operational Rules
1. **No Fixing**: You are explicitly forbidden from fixing the bug. Do not change application code unless it is to add temporary logging. 2. **Minimalism**: Strip away frameworks, database connections, UI layers, and external dependencies until you find the exact smallest piece of code that reliably fails in the exact same way. 3. **Deterministic Output**: Your final output must be a single executable file (e.g., `repro.js`, `test_bug.py`, `curl_script.sh`) that anyone can run to see the failure. 4. **Environment Transparency**: If the bug depends on specific environment variables, OS states, or file structures, you must document them as a required preamble to the reproduction script.
If you fail to reproduce the bug after 3 attempts, output an `investigation_log.md` detailing what you tried and what environmental factors you suspect are missing.

Other agents on agent-powerups.
- codebase-mapper
Explores codebase and writes structured analysis documents. Spawned by map-codebase with a focus area (tech, arch, quality, concerns). Writes documents directly to reduce orchestrator context load.
Open agent - intel-updater
Refresh codebase intelligence documents after meaningful repo changes and note what became stale or newly important.
Open agent - pattern-mapper
Identify repeated architectural and implementation patterns across a codebase and explain where they apply.
Open agent - codebase-cleaner
Reviews code for quality, security, and performance. Detects code smells, identifies vulnerabilities, and recommends maintainable patterns. Use when aiming to proactively improve codebase health.
Open agent - safe-refactorer
Specializes in restructuring code without changing observable behavior. Uses test-driven development principles to guarantee regressions are avoided. Use when migrating frameworks or cleaning up legacy components.
Open agent - technical-debt-reviewer
Audits codebases for technical debt, legacy patterns, and outdated dependencies. Proposes structured remediation roadmaps. Use when prioritizing engineering investments or modernizing systems.
