hunt-a-prod-error skillA
hunt-a-prod-error is agent-read markdown (skill) from different-ai/openwork: A user saw internal_error, "Unexpected server error", a 500, or an opaque failure in a shipped OpenWork build. Find the cause from local logs and Sentry, name the regressing PR, file the issue, and reply where it was reported..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Skill: Hunt a Prod Error
An opaque error has two halves. Local logs say **where** (route, status,
timing, burst shape). Sentry says **what** (the exception and stack). You need
both before naming a cause; either alone produces a guess.
## 1. Local logs: where and how often
Desktop server log (OTLP JSON, one record per request):
```
~/Library/Application Support/com.differentai.openwork/logs/openwork-server.log{,.1}
```
Engine log: `~/.local/share/opencode/log/opencode.log`.
Tally 5xx by route, then compare against the same route family that did
**not** fail. A failure rate on one route and zero on its siblings isolates the
code path; a burst of failures in the same millisecond points at a shared
event (GC, rollover, socket), not per-request data.
```bash
rg '"status":5' ~/Library/Application\ Support/com.differentai.openwork/logs/openwork-server.log* \
| python3 -c 'import sys,json,re,collections; c=collections.Counter()
for l in sys.stdin:
a=json.loads(l)["attributes"]; c[(a["method"], re.sub(r"(ses|ws|msg)_[A-Za-z0-9]+", r"\1_*", a["path"]), a.get("error.code"))]+=1
[print(v,k) for k,v in c.most_common()]'
```

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
