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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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()]'

How to install
mdr add different-ai/openwork/hunt-a-prod-error@sha256:5b69ac0e282279e5The line at the top of this page pins the label git:20260921.bbe08f8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
