Review limit reached

@don-petry, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 40 minutes and 12 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

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 credits.

🚦 How do rate limits work?

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

For paid Pro and Pro+ PR reviews, CodeRabbit uses rolling per-developer review limits. Reviews become available again as older review attempts age out of the rolling limit window.

Code Review

This pull request introduces scripts/mcp_connectivity_check.sh and its corresponding BATS tests to provide a durable, affirmative MCP connectivity assertion monitor. The review feedback identifies a critical issue where the script could prematurely exit under set -euo pipefail if grep finds no matching handshake lines, and suggests appending || true to the pipeline. Additionally, the reviewer recommends adding an explicit dependency check for jq to prevent silent failures, and points out a redundant assertion in the test suite.

::warning::[claude] model claude-sonnet-4-6 throttled (rc=1) — trying next in chain
The background `find` for bats completed with no results — confirming bats isn't installed locally, consistent with relying on the green CI `bats` check. No further action needed; the thread is replied and resolved, and the work is complete.

Auto-rebase failed — merge conflict — this branch has conflicts with main that must be resolved.

dev-lead will attempt to resolve this automatically. If it cannot, a follow-up comment will explain what needs manual attention.

To resolve manually instead:

git fetch origin
git merge origin/main
# resolve conflicts, then:
git add .
git commit
git push

Summary

Additive MCP/Context7 connectivity monitor for the daily PR-review health check (#903, part of #676). Adds scripts/mcp_connectivity_check.sh (pure, unit-tested helpers + an I/O main() that probes the configured server via the same engine.sh flags), a 248-line bats suite, a hashFiles-guarded step in daily-pr-review-health.yml, and the new bats file in lint.yml. Code is clean, well-scoped, and a no-op for non-MCP repos.

Linked issue analysis

Closes #903 — implements the durable, affirmative MCP-connectivity assertion the issue calls for (fails the health check when MCP is configured but unreachable; no-ops otherwise). Substantively addressed.

Findings

• All three gemini-code-assist review threads are RESOLVED and the fixes are present in the head commit:
  • HIGH: success-signal grep pipeline under `set -euo pipefail` now appends `|| true` (and classify uses grep only inside `if`).
  • MEDIUM: an explicit `command -v jq` guard now errors instead of silently skipping the assertion.
  • LOW: redundant test assertion noted (cosmetic; non-blocking).
• coderabbitai APPROVED at the reviewed head SHA; SonarCloud Quality Gate passed (0 new issues).
• Blocker: the PR is `CONFLICTING` / `DIRTY` — a live merge conflict with `main`. Auto-rebase failed (comment 2026-06-22T05:40) and dev-lead returned no-changes. The conflict must be resolved before this can merge.

CI status

All required checks green: Lint, ShellCheck, bats, unit-tests, validate-agent-profiles, gh-aw-compile, CodeQL (actions+python), SonarCloud, Secret scan (gitleaks), AgentShield, Holdout Guard, Test-Deletion Guard. Dependency-audit ecosystem jobs and dependabot-automerge SKIPPED as expected. Merge state is DIRTY (conflict with main).

Automated review — APPROVED ✓

Risk: MEDIUM
Reviewed commit: f7053fca944db12a5f09734cc058a7a130ebc635
Review mode: triage-approved (single reviewer)

Summary

Refactors scripts/mcp_connectivity_check.sh into pure, unit-tested helpers (classify_mcp_output / mcp_check_is_failure / derive_allowed_tools / mcp_check_report) plus an I/O main(), and wires the daily health-check step behind a hashFiles('.github/review-mcp.json') guard. Net +354/-326 across 4 files; CI-only monitoring tooling.

Linked issue analysis

Closes #903 (part of #676). The PR delivers the durable, affirmative MCP/Context7 connectivity assertion the issue calls for: it drives the configured server(s) through the same flags engine.sh uses (--mcp-config --strict-mcp-config --debug mcp) and fails the daily health check when MCP is configured but unreachable. .github/review-mcp.json is present in the repo, so the new hashFiles guard fires and the monitor actually runs rather than no-opping.

Findings

No blocking findings.

• Advisory bot (gemini-code-assist) had flagged a set -euo pipefail premature-exit on the handshake grep, a missing jq dependency guard, and a redundant test assertion. The current head incorporates the fixes: '|| true' terminates the handshake-emit pipeline, an explicit jq guard returns 1 with ::error::, and a 'main: jq missing' test covers it.
• Deliberate, internally-consistent behavior changes vs. the prior version: (a) an explicitly-set-but-missing REVIEW_MCP_CONFIG now no-ops (exit 0) instead of fail-loud (exit 1) — moot in practice behind the workflow hashFiles guard; (b) classify_mcp_output returns CONNECTED when any handshake is present even if a later line shows a failure (handshake-wins). For the single-server Context7 use case this is fine; worth a note only if multi-server configs are later added.
• Security: no secrets/credentials; cfg/allowed/model passed positionally to claude/jq (no shell injection); workflow change is an if-guard tightening plus adding the bats file to the lint list — no GitHub Actions security smells.

CI status

All required checks green: shellcheck/ShellCheck, bats, unit-tests, Lint, CodeQL (actions+python), Secret scan (gitleaks), SonarCloud, AgentShield, validate-agent-profiles, holdout-guard, guard. dependency-audit ecosystem jobs and dependabot-automerge correctly SKIPPED. CodeRabbit check state SUCCESS.
