Harden one or more providers' live test suites until they are stable — repeat full suite runs with a leak census after each, root-cause every failure and leak (provider bug first, then distilled patch, then test, timeouts last), make every name and stage deterministic and isolated per user and worktree, and stop only when consecutive runs are green and clean. Use for "harden cloudflare", "harden the aws provider", "/harden gcp neon", "make the X suite stable…
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.

# Harden a provider's test suite
A suite is hardened when it passes **two consecutive full runs** and the
account census after each run shows nothing left behind. One green run proves
little: most of what this skill finds only shows up in some runs — eventual
consistency, retries that leak, other users or worktrees deploying the same
names, an API that sometimes ignores a write.
The arguments name the providers (`cloudflare`, `aws gcp`, …). You own the
runs, the fixes, the census and the commits. Work in this checkout, one test
process at a time. Fixes land in the branch you are on (the release PR when
prepare-release invoked you). The user merges; you never do.
## The loop
1. **Run the provider's full suite once.** Detach it and write its output to
a numbered file, then census:
```sh
pnpm test:integration test/<Provider> --profile testing > /tmp/harden/run-N.out 2>&1
pnpm nuke --profile testing --include '<Provider>.*' --dry-run --no-input > /tmp/harden/census-N.out
echo "run N: $(grep '^Tests:' /tmp/harden/run-N.out)" >> /tmp/harden/stability.log
```
Keep `stability.log` as the table you report: one line per run, plus what
the census found.
…
The line at the top of this page pins the label git:20261104.43bf0ba, 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.
