Which of the PR Types Shown Require Approval?
Understanding when a pull request (PR) must be signed off before it can be merged is a cornerstone of healthy collaborative development. Whether you are working in a small startup or a large enterprise, knowing the approval rules for each PR type helps teams avoid broken builds, security gaps, and unnecessary rework. This article breaks down the most common PR categories you’ll encounter in platforms like GitHub, GitLab, and Bitbucket, explains which of them demand formal approval, and offers practical guidance for setting up a workflow that balances speed with safety.
Introduction: Why PR Approval Matters
A pull request is more than a notification that code is ready; it is a contract between the contributor and the rest of the team. The approval step acts as a gatekeeper that verifies:
- Correctness – Does the change solve the intended problem without introducing bugs?
- Quality – Does it follow coding standards, include tests, and maintain readability?
- Security – Are there no accidental secrets, unsafe dependencies, or vulnerable patterns?
- Alignment – Does the work fit the current sprint, release plan, or architectural roadmap?
When a PR type is marked as “requires approval,” the team enforces that at least one designated reviewer (often a senior engineer, tech lead, or domain expert) must sign off before the merge button becomes active. Conversely, PR types that do not require approval are usually low‑risk, automated, or explicitly marked as drafts or work‑in‑progress Not complicated — just consistent. Took long enough..
Common PR Types and Their Typical Approval Rules
Below is a table summarizing the PR varieties you’ll most often see, together with the default approval expectation in a standard Git‑based workflow. Note that exact policies can be customized via branch protection rules, CODEOWNERS files, or CI‑gate configurations, but the defaults described here reflect industry‑wide conventions.
| PR Type | Typical Use Case | Default Approval Requirement | Why Approval Is (or Isn’t) Needed |
|---|---|---|---|
| Feature PR | New functionality developed on a feature branch | Yes (at least one approver) | Introduces user‑visible change; needs functional review and test verification. That said, |
| Bugfix PR | Patch for a reported defect | Yes (at least one approver) | Even small fixes can regress other areas; approval ensures the fix is correct and doesn’t hide the root cause. |
| Hotfix / Emergency PR | Urgent production fix, often branched from main or release |
Yes (often required, but may be expedited) | High risk if applied incorrectly; many teams require a fast‑track approval from a lead or on‑call engineer. Day to day, |
| Release PR | Prepares a version bump, changelog, and release notes | Yes (usually multiple approvers) | Touches versioning and packaging; mistakes can affect downstream consumers. So |
| Documentation PR | Updates to README, wiki, API docs, or guides | Sometimes (often optional) | Purely textual changes are low risk; many teams allow self‑merge after CI passes, but may still require a quick glance for accuracy. Worth adding: |
| Dependency Update PR | Bump of library versions (often generated by tools like Dependabot) | Conditional (depends on policy) | If the update is minor/patch and passes automated tests, some teams allow auto‑merge; major version bumps usually need human approval. |
| Refactor / Cleanup PR | Internal code restructuring without behavior change | Yes (often optional but recommended) | Refactors can be subtle; approval helps catch accidental logic changes or missing test updates. |
| Test‑Only PR | Adds or modifies unit/integration tests | Sometimes (often optional) | Pure test additions are safe, but approval ensures tests are meaningful and not just placeholders. |
| Draft / WIP PR | Work‑in‑progress, not ready for review | No (explicitly blocked from merging) | The draft status itself signals that the PR is not yet approvable; reviewers are invited to comment but cannot approve. |
| Chore / Misc PR | Build script tweaks, CI configuration, linting fixes | Sometimes (often optional) | Low risk, but many teams still require a quick sign‑off to avoid breaking the pipeline. |
Key Takeaway: All PR types that intend to modify production code (features, bugfixes, hotfixes, releases, refactors, and most dependency updates) typically require at least one formal approval. The only categories that commonly bypass approval are drafts, documentation‑only, test‑only, and certain dependency‑update or chore PRs—provided that automated checks (CI, linting, security scans) have passed and the team’s policy explicitly permits it.
No fluff here — just what actually works.
How Approval Requirements Are Enforced
Modern Git hosting platforms let you codify approval rules via branch protection and CODEOWNERS configurations. Here’s a typical setup that matches the table above:
-
Branch Protection Rules (applied to
main,release/*, andhotfix/*branches)- Require pull request reviews before merging.
- Set minimum number of approvers (e.g., 1 for feature/bugfix, 2 for release).
- Include status checks that must pass (CI build, unit tests, security scan).
-
CODEOWNERS File
- Define owners for specific paths (e.g.,
/docs/owned by the documentation team). - When a PR touches only those paths, the rule can be relaxed to optional review (if the team opts for “skip documentation approval”).
- Define owners for specific paths (e.g.,
-
Draft PR Mechanism
- Platforms automatically block merging while a PR is in draft mode.
- Reviewers can leave comments, but the “Approve” button stays disabled until the PR is marked ready for review.
-
Automation Bots (e.g., Dependabot, Renovate) * Can be configured to auto‑merge on minor/patch updates after CI passes.
- Major version bumps stay in a “requires approval” state unless the team explicitly whitelists them.
By combining these mechanisms, you create a tiered approval model where the rigor matches the risk level of each PR type.
When Approval Can Be Safely Waived
Even though the default is to require approval, there are legitimate scenarios where teams choose to bypass it:

WhenApproval Can Be Safely Waived
Even though the default is to require approval, there are legitimate scenarios where teams choose to bypass it. The key is that the waiver must be explicit, well‑documented, and backed by compensating safeguards that mitigate the added risk.
| Scenario | Why a Waiver Is Acceptable | Compensating Safeguard |
|---|---|---|
| Minor dependency bumps (patch or minor version) | The upstream project has a strict semantic‑versioning policy, and the change has been vetted by automated security scanners. In real terms, | Test suite must achieve ≥ 90 % coverage on the modified files, and the pipeline fails on any test regression. |
| One‑off hotfixes to production when a rollback is impossible | Immediate remediation is required to avoid service outage. Which means | A lint step that validates markdown links and structure runs on every PR; reviewers can rely on the bot to catch broken references. |
| Feature flags that are gated behind a toggle | The code path is never executed until the flag is turned on, allowing the team to ship early and validate in production. md` files | No runtime impact; the only risk is outdated information. |
| Test‑only changes (e.g. | ||
Documentation updates confined to /docs/ or `*.Think about it: , adding a unit test or fixture) |
Tests do not affect production code; they only increase coverage. | The flag must be merged only after a successful canary deployment and a post‑deployment health check. |
Bottom line: Waivers are permissible only when the risk surface is narrow, automated verification is exhaustive, and a clear rollback or mitigation path exists.
Building a dependable Approval Workflow
-
Define Clear Policy Thresholds
- Zero‑approval for low‑risk PRs (docs, tests).
- One‑approval for most feature and bug‑fix PRs.
- Two‑approval for release‑candidate and hotfix PRs.
-
make use of Branch‑Protection Settings * Enforce “require pull‑request reviews before merging”.
- Set “required status checks” to include unit tests, integration tests, and security scans.
-
Automate the “Ready‑to‑Merge” Gate
- Use a bot that automatically adds a “ready‑to‑merge” label once CI passes, all required reviewers have approved, and the PR is not a draft.
- The bot can then trigger a merge via the platform’s API, eliminating manual clicks.
-
Track Exceptions Transparently
- Maintain a lightweight log (e.g., a markdown file in the repo) that records every waived approval, the PR number, the reason, and the approver who signed off.
- Review this log during sprint retrospectives to spot patterns that may warrant policy adjustment.
-
Educate the Team
- Conduct a brief “approval‑policy 101” session at the start of each quarter.
- Provide cheat‑sheet diagrams that map PR type → required approvals → typical safeguards.
Frequently Asked Questions
| Question | Answer |

| What if a reviewer forgets to approve? | Treat it like a normal feature PR. That said, |
| **What if a PR passes CI but introduces a performance regression? ** | Include a performance‑testing job in the CI pipeline. Plus, ** |
| **Is there a way to “fast‑track” a PR during an incident?Most platforms allow a “re‑open” button for the author to ping the reviewer, but the merge will still be prevented until the approval is recorded. This is discouraged for high‑risk changes. Worth adding: if it fails, the PR will be blocked regardless of approvals. On top of that, | |
| **How do I handle a PR that adds a new feature flag? | |
| **Can a PR have “approval‑by‑default” for certain authors?Once the flag is merged, the code can be merged with a single approval because the flag prevents exposure to end users. Which means ** | The PR remains blocked. ** |
Conclusion Pull‑request approvals are not a one‑size‑fits‑all rule; they
are a dynamic process that should evolve alongside your team’s maturity and project needs. Because of that, implementing a structured approval workflow, as outlined above, provides a solid foundation, but it’s crucial to remain flexible and adapt based on your specific context. Which means regularly reviewing the exception log, soliciting feedback from the team, and adjusting policy thresholds are vital for maintaining an effective system. Don’t treat the approval process as a rigid gatekeeper, but rather as a mechanism to enhance code quality, reduce risk, and grow a culture of shared responsibility. Worth adding: ultimately, the goal isn’t simply to require approvals, but to guide the team towards producing reliable and reliable software. By combining clear policies with automated tools and ongoing communication, you can transform pull-request approvals from a potential bottleneck into a powerful contributor to your development process.
