A bug-reproduction workflow that records a mobile app test as video and collects React Native logs and crash reports around the same attempt.

In plain words
What is it for?
Replaying described steps on an iOS simulator, saving a video, checking Metro output, checking recent crashes, and summarizing the evidence.
Why use it?
It creates a single evidence package for deciding whether a bug occurred and investigating what happened.

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

bug-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 2mo 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

Parse $ARGUMENTS as:

  • token 1 → UDID
  • token 2 → BUNDLE_ID
  • remaining text → bug description / repro steps

Execute in this exact order (await each call):

  1. record_start — saveTo /tmp/repro-<BUNDLE_ID>.mp4
  2. inspect_screen on the UDID — capture the starting state
  3. Author and call run_flow with an inline Maestro YAML that encodes the repro steps. Use only selectors from step 2.
  4. record_stop
  5. metro_logs — durationMs 4000, maxLogs 100 — capture console output around the repro
  6. crash_list — udid UDID, sinceHours 1 — check for new crashes

Summarize:

  • Did the bug reproduce? (REPRODUCED / NOT REPRODUCED / INCONCLUSIVE)
  • Video path + sizeBytes from record_stop
  • Relevant log lines (errors/warnings only)
  • Any new crash entry (exception type + top frame)
  • Root-cause hypothesis with evidence

If Metro is not running, note it and skip step 5 — do not fail the whole repro.

Changes

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.
