create-repro

create-repro is a command for Claude Code from yeaight7/agent-powerups. It costs 16 tokens per session (280 once invoked), scanned A, original, Apache-2.0.

A command that turns a bug report into a small, standalone script or test that still fails in the reported way.

In plain words
What is it for?
Use it to isolate a failing component, run the reproduction, and capture the exact command and output needed for further debugging.
Why use it?
A minimal reproduction removes unrelated setup and makes the failure easier to understand and share. It verifies the failure before any application code is changed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-repro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Create Reproduction

CRITICAL BEHAVIORAL RULES

  1. Stop at Reproduction: Your goal is a failing test, not a passing test. Do not fix the application code.
  2. Verify the Failure: You must run your reproduction script and verify that its output matches the reported bug before presenting it.

Execution Steps

  1. Read the Report: Analyze $ARGUMENTS to understand the expected behavior vs. the actual behavior.
  2. Draft a Minimal Script: Create repro.<ext> (or a standalone test file) that isolates the failing component. Strip out unrelated setup, routing, or UI logic.
  3. Execute: Run the script.
    • If it passes: You missed the bug context. Add back complexity until it fails.
    • If it fails with a different error: You missed a dependency or setup step. Fix the setup.
    • If it fails with the reported error: You succeeded.
  4. Finalize: Output the exact command to run the script and the output it generates. Ask the user if they want to pass this repro to the root-cause-debugger or debug command.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
