CodeRabbit's review of #16 landed after I merged it. All four findings were valid; two are real logic holes in the /upgrade skill that PR introduced.

My process error, plainly

I recorded the fallback review receipt on #16 while CodeRabbit's check read PENDING — Review queued. The doctrine says a bot being unavailable triggers the substitute pass; queued is not unavailable, it's slow. Earlier PRs in this batch genuinely were rate-limited, and I carried that assumption forward instead of re-reading the state. The gate behaved correctly — green, clean, receipt bound to the head — it just cannot know a queued review will land in two minutes.

Worth noting the mechanism can't fix this on its own: decide_done has no way to distinguish "no review is coming" from "a review is queued". A possible follow-up is for pr_watch to treat a configured bot's own status check sitting PENDING as a blocker rather than as informational when no receipt exists yet — happy to file that if you want it.

The four findings

1 (major) — /upgrade mutated before branching. Step 2 ran ./init.sh, which rewrites config, installs hooks, and renders docs, while the branch wasn't created until Step 3. Migration could land on whatever branch the operator was on — directly contradicting the skill's own "runs on a branch" guarantee. Branch creation moved ahead of the first mutation; the now-duplicate Step 3 branch command replaced with a git branch --show-current confirmation.

2 (major) — /upgrade ran a stale migrator. It fetched the current kit, then invoked the target repo's existing init.sh — the old one, lacking the new schema migrations. An upgrade would report success while applying none of them. That is precisely the silent-no-op class this whole stack has been removing, reintroduced in the tool meant to deliver the fixes. init.sh is now refreshed from the fetched kit before being run, with a chmod +x note since a plain copy can drop the executable bit (which is how #8's first CI run failed).

3 (minor) — em dash in a shell code block. python scripts/kit_doctor.py — stdlib only passes the em dash and the words as arguments if copy-pasted. Now a real # comment.

4 (major) — check_doc_budget.py crashed instead of exiting cleanly. A config with no doc_budgets section produced an unhandled KeyError traceback rather than the intended one-line error and exit 2.

One correction to the finding: CodeRabbit attributed this to "the new fail-loud get()", implying #16 introduced it. It didn't — devmodel_config.get was equally fail-loud with no default, and main() already caught only (FileNotFoundError, ValueError). The gap predates the kitconfig switch. Verified against HEAD~1. Valid bug regardless; now caught, with a subprocess-level regression test asserting exit 2 and no traceback.

Verification

188 tests pass. The manifest CI gate caught its own stale hash after I edited check_doc_budget.py — regenerated. Confirmed the fix empirically:

$ uv run scripts/check_doc_budget.py --config /tmp/nobudget.yaml
error: "required config key 'doc_budgets' not found (missing at 'doc_budgets')"
exit=2

The review landed AFTER the merge — I treated a queued bot as an unavailable one
and recorded the fallback receipt too early. Details in the PR body. All four
findings were valid; two are real logic holes in the /upgrade skill.

1. (major) /upgrade mutated before branching. Step 2 ran init.sh — which
   rewrites config, installs hooks, and renders docs — while the branch was not
   created until Step 3, so the migration could land on whatever branch the
   operator was on, contradicting the skill's own "runs on a branch" guarantee.
   Branch creation moved ahead of the first mutation; the duplicate step in
   Step 3 replaced with a confirmation.

2. (major) /upgrade ran a stale migrator. It fetched the current kit and then
   invoked the TARGET repo's existing init.sh — the old one, without the new
   schema migrations — so an upgrade would report success while applying none of
   them. The exact silent-no-op class this stack has been removing. init.sh is
   now refreshed from the fetched kit before being run, with a chmod +x note
   since a copy can drop the bit.

3. (minor) An em dash inside a shell code block in README became an argument if
   copy-pasted. Replaced with a real shell comment.

4. (major) check_doc_budget.py crashed with an unhandled KeyError on a config
   with no doc_budgets section, instead of the intended one-line error + exit 2.
   CodeRabbit attributed this to the new fail-loud get(); that attribution is
   wrong — devmodel_config.get was equally fail-loud and main() already caught
   only (FileNotFoundError, ValueError), so the gap predates the kitconfig
   switch. Valid bug either way, now caught, with a subprocess-level regression
   test asserting exit 2 and no traceback.

Manifest regenerated (the CI gate caught the stale hash, as designed).

Warning

Review limit reached

@topij, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 41 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Caught by the fallback review pass on this PR. init.sh resolves
docs/templates/*.tmpl relative to the WORKING DIRECTORY, so Step 2 ran the
refreshed migrator before Step 4 had copied the templates in — it prints
'note: template … missing — skipped' and seeds nothing.

Harmless noise for a repo whose narrative docs are already in use (they would
be left untouched regardless), but a PARTIALLY-adopted repo missing one of the
four docs would silently not get it seeded — and partial adoptions are the
common shape, not the exception.

Verified both directions: templates absent -> four 'skipped' notes and no
seeding; templates present -> seeded. Also corrected the claim that running the
fetched kit's init.sh in place is 'equivalent' — every path it reads resolves
against the working directory, so it needs the templates here either way.
