+
+# Check PR
+
+Analyze a pull request (GitHub), merge request (GitLab), or shelved changelist (Perforce) for review comments, status checks, and description completeness, then help address any issues found.
+
+## Inputs
+
+- **PR/MR/CL number** (optional): If not provided, detect the PR/MR for the current branch, or the default pending changelist for p4.
+
+## Instructions
+
+### 0. Detect platform
+
+First check if the user is working in a Perforce depot by looking for a `.p4config` file or `P4CLIENT`/`P4PORT` environment variables:
+
+```bash
+# Check for Perforce environment
+if p4 info >/dev/null 2>&1; then
+  VCS="perforce"
+else
+  # Fall back to git remote detection
+  REMOTE_URL=$(git remote get-url origin)
+  if echo "$REMOTE_URL" | grep -qi "gitlab"; then
+    VCS="gitlab"
+  else
+    VCS="github"
+  fi
+fi
+```
+
+For self-hosted GitLab instances whose hostname doesn't contain "gitlab", the user can override by passing `--vcs gitlab` as an input. For Perforce, the user can override by passing `--vcs perforce`.
+
+### 1. Identify the PR/MR/CL
+
+If a number was provided, use it. Otherwise, detect it:
+
+**GitHub:**
+```bash
+gh pr view --json number,headRefName,headRefOid -q '{number: .number, branch: .headRefName, head: .headRefOid}'
+```
+
+**GitLab:**
+```bash
+glab mr view --output json | jq '.iid'
+```
+
+**Perforce:**
+```bash
+# List pending changelists for the current user/client
+p4 changes -s pending -u $P4USER -c $P4CLIENT
+```
+
+Key field differences between platforms:
+- GitHub: `number`, `headRefName`, `headRefOid`
+- GitLab: `iid`, `source_branch`, `sha`
+- Perforce: changelist number (CL), `shelved` files for in-review CLs
+
+### 2. Fetch PR/MR/CL details
+
+**GitHub:**
+```bash
+gh pr view <PR_NUMBER> --json title,body,state,reviews,comments,headRefName,headRefOid,statusCheckRollup
+OWNER_REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+gh api "repos/$OWNER_REPO/pulls/<PR_NUMBER>/comments"
+gh api --paginate "repos/$OWNER_REPO/issues/<PR_NUMBER>/comments?per_page=100"
+```
+
+GitHub PRs are also issues, so general PR comments live on the issue comments endpoint. Greptile may edit a single general PR comment on each review cycle instead of creating a new review or comment. Always inspect the latest Greptile-authored general comment by `updated_at`, including any "Prompt to fix all with AI" section, before concluding that the PR is clear.
+
+**GitLab:**
+```bash
+glab mr view <MR_IID> --output json
+# Fetch discussions (inline diff comments are type "DiffNote"; general comments have null type)
+glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions"
+```
+
+For GitLab, paginate discussions if needed (add `?per_page=100&page=N`).
+
+**Perforce:**
+```bash
+# Get changelist description, files, and status
+p4 describe -s <CL_NUMBER>
+
+# Get shelved files (for in-review CLs)
+p4 describe -S <CL_NUMBER>
+
+# Get the diff of the shelved changelist
+p4 diff2 //...@=<CL_NUMBER> //...@=<CL_NUMBER>
+
+# List review comments (if using p4 review workflow)
+p4 review -c <CL_NUMBER>
+```
+
+Key Perforce CL fields:
+- `Change`: changelist number
+- `Status`: `pending`, `submitted`, `shelved`
+- `Description`: the CL description / commit message
+- `Files`: list of files in the CL
+
+### 3. Wait for pending checks
+
+Before analyzing, ensure all status checks have completed. If any checks are `PENDING` or `IN_PROGRESS` (GitHub) / `running` or `pending` (GitLab), poll every 30 seconds until all checks reach a terminal state.
+
+**GitHub:** poll `statusCheckRollup` from `gh pr view`.
+
+**GitLab:**
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/pipelines"
+```
+Pipeline statuses: `running`, `pending`, `success`, `failed`, `canceled`, `skipped`. Poll until no pipeline has `running` or `pending` status.
+
+**Perforce:** Perforce doesn't have built-in CI checks natively. If the team uses a review tool (Swarm, etc.) or an external CI triggered by shelve events, check the relevant system. Otherwise, proceed to analysis immediately.
+
+### 4. Require a fresh Greptile review for the current head
+
+For GitHub PRs, do not treat an existing Greptile review, comment, or summary as current unless it is tied to the PR's exact current `headRefOid`. This is especially important after pushing a new commit to an existing PR: a Greptile review on an older commit is stale, even if the PR still has a Greptile comment or prior review.
+
+Fetch the current head SHA immediately before the Greptile gate:
+
+```bash
+HEAD_SHA=$(gh pr view <PR_NUMBER> --json headRefOid -q .headRefOid)
+```
+
+Then inspect check-runs for that commit and require a completed Greptile run:
+
+```bash
+OWNER_REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+GREPTILE_CHECKS=$(gh api "repos/$OWNER_REPO/commits/$HEAD_SHA/check-runs?per_page=100" \
+  --jq '[.check_runs[] | select(.name | test("greptile"; "i"))]')
+
+# A run only counts as a valid fresh pass when it has completed AND concluded cleanly.
+# GitHub check-run conclusions: success, neutral, skipped, failure, timed_out,
+# cancelled, action_required, stale. Treat success/neutral as clean;
+# everything else (especially failure and action_required) must block.
+FRESH_GREPTILE_COMPLETED=$(echo "$GREPTILE_CHECKS" \
+  | jq '[.[] | select(.status == "completed")] | length')
+FRESH_GREPTILE_CLEAN=$(echo "$GREPTILE_CHECKS" \
+  | jq '[.[] | select(.status == "completed" and (.conclusion | IN("success","neutral")))] | length')
+FRESH_GREPTILE_BLOCKING=$(echo "$GREPTILE_CHECKS" \
+  | jq '[.[] | select(.status == "completed" and ((.conclusion | IN("success","neutral")) | not))] | length')
+
+if [ "$FRESH_GREPTILE_COMPLETED" = "0" ]; then
+  echo "Blocked: no completed Greptile review/check is tied to current PR head $HEAD_SHA."
+  echo "Request a fresh Greptile review against this head before marking the PR check done."
+  echo "Suggested trigger: gh pr comment <PR_NUMBER> --body \"@greptile review\""
+  exit 1
+fi
+
+if [ "$FRESH_GREPTILE_BLOCKING" != "0" ] || [ "$FRESH_GREPTILE_CLEAN" = "0" ]; then
+  echo "Blocked: Greptile completed on head $HEAD_SHA but did not conclude clean"
+  echo "(conclusion was failure/action_required/timed_out/cancelled/stale, or no clean run exists)."
+  echo "Address the findings, push, and re-run Greptile until it concludes success/clean on the new head."
+  exit 1
+fi
+```
+
+If a Greptile check exists for the current head but is still pending or in progress, wait for it with the same polling pattern used by `greploop` rather than proceeding from older review material. If no Greptile check appears for the current head after a reasonable wait, report the PR as blocked on a fresh Greptile review for `HEAD_SHA` and stop. Do not mark the check complete from PR comments, PR reviews, or Greptile summaries that cannot be associated with the current head SHA.
+
+For GitLab installations with Greptile integration, apply the same freshness rule against the MR's current head SHA:
+
+```bash
+# 1. Get the MR's current head SHA
+MR_SHA=$(glab mr view <MR_IID> --output json | jq -r '.sha // .diff_refs.head_sha')
+
+# 2. Find the latest pipeline for that EXACT sha, then the Greptile job within it.
+LATEST_PIPELINE_ID=$(glab api "projects/:fullpath/merge_requests/<MR_IID>/pipelines" \
+  | jq -r --arg sha "$MR_SHA" '[.[] | select(.sha == $sha)] | sort_by(.id) | last | .id // empty')
+
+if [ -n "$LATEST_PIPELINE_ID" ]; then
+  GREPTILE_JOBS=$(glab api "projects/:fullpath/pipelines/$LATEST_PIPELINE_ID/jobs" \
+    | jq --arg sha "$MR_SHA" '[.[] | select(.name | test("greptile"; "i"))
+        | {name, status, pipeline_sha: $sha}]')
+else
+  GREPTILE_JOBS='[]'
+fi
+
+GREPTILE_JOB_SUCCESS=$(echo "$GREPTILE_JOBS" \
+  | jq '[.[] | select(.status == "success")] | length')
+GREPTILE_JOB_BLOCKING=$(echo "$GREPTILE_JOBS" \
+  | jq '[.[] | select(.status != "success")] | length')
+
+# 3. If Greptile integrates via MR notes instead of a CI job, require the newest
+#    Greptile note to reference the current head sha and report a clean review.
+GREPTILE_NOTES=$(glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions?per_page=100" \
+  | jq --arg sha "$MR_SHA" '[.[].notes[]
+      | select(.author.username | test("greptile"; "i"))]
+      | sort_by(.updated_at // .created_at)')
+GREPTILE_NOTE_CLEAN=$(echo "$GREPTILE_NOTES" \
+  | jq --arg sha "$MR_SHA" 'if length == 0 then 0
+      elif ((last.body // "") | contains($sha) and test("Confidence Score:[[:space:]]*5/5|Confidence:[[:space:]]*5/5|\\b5/5\\b"; "i") and (test("Prompt To Fix|blocking issue|failed|action required"; "i") | not)) then 1
+      else 0 end')
+
+if [ "$GREPTILE_JOB_SUCCESS" = "0" ] && [ "$GREPTILE_NOTE_CLEAN" = "0" ]; then
+  echo "Blocked: no successful Greptile job or completed-clean current-head Greptile note is tied to MR head $MR_SHA."
+  exit 1
+fi
+
+if [ "$GREPTILE_JOB_BLOCKING" != "0" ]; then
+  echo "Blocked: at least one Greptile job for MR head $MR_SHA did not succeed."
+  exit 1
+fi
+```
+
+Block completion if, for `MR_SHA`, there is (a) no Greptile job or note at all (missing), (b) the newest Greptile job/note is tied to a different sha (stale), or (c) the Greptile job status is not `success`. A completed Greptile result for a different SHA is stale and must block completion.
+
+For Perforce installations with Greptile integration, apply the same rule using the CL's current shelved-revision identity and the Greptile webhook/review artifact tied to it; a Greptile result for an earlier shelf is stale and must block completion.
+
+### 5. Analyze the PR/MR
+
+Once all checks are complete, evaluate these areas:
+
+#### A. Status Checks
+
+- Are all CI checks passing?
+- If any are failing, identify which ones and the failure reason.
+
+#### B. PR/MR Description
+
+- Is the description complete and follows team conventions?
+- Are all required sections filled in?
+- Are there TODOs or placeholders that need updating?
+
+#### C. Review Comments
+
+- Inline code review comments that need addressing
+- Look for bot review comments (e.g. from `greptile-apps[bot]` on GitHub, or the Greptile bot user on GitLab, linters, etc.)
+- Human reviewer comments
+- **Perforce:** review comments from `p4 review` or external review tools
+
+#### D. General Comments
+
+- Discussion comments on the PR/MR
+- For GitHub, check the issue comments endpoint and use `updated_at` to catch bot comments edited in place. Greptile's latest edited summary can contain actionable items even when there are no new inline comments.
+- Bot comments (deploy previews, etc.) - usually informational
+- **Perforce:** CL description should include a clear summary, affected files rationale, and testing notes
+
+### 6. Categorize issues
+
+For each issue found, categorize as:
+
+| Category | Meaning |
+|---|---|
+| **Actionable** | Code changes, test improvements, or fixes needed |
+| **Informational** | Verification notes, questions, or FYIs that don't require changes |
+| **Already addressed** | Issues that appear to be resolved by subsequent commits |
+
+### 7. Report findings
+
+Present a summary table:
+
+| Area | Issue | Status | Action Needed |
+|------|-------|--------|---------------|
+| Status Checks | CI build failing | Failing | Fix type error in `src/api.ts` |
+| Review | "Add null check" - @reviewer | Actionable | Add guard clause |
+| Description | TODO placeholder in test plan | Actionable | Fill in test plan |
+| Review | "Looks good" - @teammate | Informational | None |
+
+### 8. Fix issues (if requested)
+
+If there are actionable items:
+
+1. Switch to the PR/MR's branch (git) or ensure files are open in the correct CL (Perforce) if not already.
+2. Ask the user if they want to fix the issues.
+3. If yes, make the fixes, then:
+
+**GitHub/GitLab:** commit and push:
+```bash
+git add <files>
+git commit -m "address review feedback"
+git push
+```
+
+**Perforce:** open files for edit, make changes, and re-shelve:
+```bash
+p4 edit <file>
+# make changes
+p4 shelve -f -c <CL_NUMBER>
+```
+
+### 9. Resolve review threads
+
+After addressing comments, resolve the corresponding review threads.
+
+**Perforce** - Perforce does not have a native "resolve thread" concept. Instead, mark comments as addressed by updating the CL description or by responding in the review tool being used (Swarm, etc.). If using `p4 review`:
+
+```bash
+# Mark files as reviewed after addressing feedback
+p4 review -c <CL_NUMBER>
+```
+
+**GitHub** - fetch unresolved thread IDs (paginate if needed - see [the GraphQL reference](references/graphql-queries.md)):
+
+```bash
+gh api graphql -f query='
+query($cursor: String) {
+  repository(owner: "OWNER", name: "REPO") {
+    pullRequest(number: PR_NUMBER) {
+      reviewThreads(first: 100, after: $cursor) {
+        pageInfo { hasNextPage endCursor }
+        nodes {
+          id
+          isResolved
+          comments(first: 1) {
+            nodes { body path }
+          }
+        }
+      }
+    }
+  }
+}'
+```
+
+If `hasNextPage` is true, repeat with `-f cursor=ENDCURSOR` to get remaining threads.
+
+Then resolve threads that have been addressed or are informational:
+
+```bash
+gh api graphql -f query='
+mutation {
+  resolveReviewThread(input: {threadId: "THREAD_ID"}) {
+    thread { isResolved }
+  }
+}'
+```
+
+Batch multiple resolutions into a single mutation using aliases (`t1`, `t2`, etc.).
+
+**GitLab** - fetch unresolved discussions (see [the GitLab API reference](references/gitlab-api.md)):
+
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions?per_page=100"
+```
+
+Filter for discussions where `"resolved": false`. Collect each discussion's `id`.
+
+Resolve each discussion individually (GitLab has no batch resolution):
+
+```bash
+glab api --method PUT \
+  "projects/:fullpath/merge_requests/<MR_IID>/discussions/<DISCUSSION_ID>" \
+  --field resolved=true
+```
+
+Repeat for each unresolved discussion ID.
+
+### 10. Multiple PRs/MRs/CLs
+
+If checking a chain of PRs/MRs/CLs, process them sequentially.
+
+**Perforce** - to check multiple changelists at once:
+```bash
+p4 changes -s pending -u $P4USER -c $P4CLIENT -l
+```
+
+## Output format
+
+Summarize:
+- PR/MR/CL title or description and current state
+- Platform detected (GitHub / GitLab / Perforce)
+- Status checks summary (passing/failing/pending) - or N/A for Perforce
+- Total issues found
+- Actionable items with descriptions
+- Items that can be ignored with reasons
+- Recommended next steps

+# GitLab API Reference
+
+Useful GitLab REST API calls for working with merge request discussions, using `glab api`.
+
+`glab api` automatically resolves `:fullpath` to the URL-encoded project path from the local git remote.
+
+## Fetch MR details
+
+```bash
+glab mr view <MR_IID> --output json
+```
+
+Key fields (compared to GitHub equivalents):
+- `iid` - internal MR number (use this, not `id`)
+- `source_branch` - equivalent to GitHub's `headRefName`
+- `sha` - HEAD commit SHA, equivalent to GitHub's `headRefOid`
+- `description` - equivalent to GitHub's `body`
+
+## Fetch all discussions (inline + general comments)
+
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions?per_page=100"
+```
+
+Paginate with `&page=2`, `&page=3`, etc. until the response array length is less than `per_page`.
+
+Each discussion object:
+- `id` - discussion ID (used for resolution)
+- `resolved` - `true` or `false`
+- `notes` - array of note objects
+
+Each note object:
+- `type` - `"DiffNote"` for inline diff comments, `null` for general comments
+- `author.username` - author's username
+- `body` - comment text
+- `position.new_path` - file path (for `DiffNote` type)
+
+## Filter for unresolved inline diff comments
+
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions?per_page=100" | \
+  jq '[.[] | select(.resolved == false and (.notes[0].type == "DiffNote"))]'
+```
+
+## Resolve a single discussion
+
+```bash
+glab api --method PUT \
+  "projects/:fullpath/merge_requests/<MR_IID>/discussions/<DISCUSSION_ID>" \
+  --field resolved=true
+```
+
+There is no batch resolution in GitLab - issue one PUT per discussion.
+
+## Fetch pipeline status for an MR
+
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/pipelines"
+```
+
+Pipeline statuses: `running`, `pending`, `success`, `failed`, `canceled`, `skipped`.
+
+## Fetch jobs for a specific pipeline
+
+```bash
+glab api "projects/:fullpath/pipelines/<PIPELINE_ID>/jobs"
+```
+
+Each job has `name`, `status`, `stage`, and `web_url`.
+
+## Fetch MR notes (general comments and bot reviews)
+
+```bash
+glab api "projects/:fullpath/merge_requests/<MR_IID>/notes?per_page=100"
+```
+
+Filter by `author.username` to find Greptile bot comments. The exact bot username depends on the Greptile installation - check the first Greptile comment to identify it.
+
+## Post a comment on an MR
+
+```bash
+glab mr note <MR_IID> --message "your message here"
+```
+
+Or via API:
+
+```bash
+glab api --method POST \
+  "projects/:fullpath/merge_requests/<MR_IID>/notes" \
+  --field body="your message here"
+```

+# GraphQL Queries Reference
+
+Useful GitHub GraphQL queries for working with PR review threads.
+
+## Fetch unresolved review threads (with pagination)
+
+```graphql
+query($cursor: String) {
+  repository(owner: "OWNER", name: "REPO") {
+    pullRequest(number: PR_NUMBER) {
+      reviewThreads(first: 100, after: $cursor) {
+        pageInfo {
+          hasNextPage
+          endCursor
+        }
+        nodes {
+          id
+          isResolved
+          comments(first: 3) {
+            nodes {
+              body
+              path
+              author { login }
+              createdAt
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+Pass `-f cursor=ENDCURSOR` on subsequent requests if `hasNextPage` is `true`.
+
+## Resolve a single review thread
+
+```graphql
+mutation {
+  resolveReviewThread(input: {threadId: "THREAD_ID"}) {
+    thread { isResolved }
+  }
+}
+```
+
+## Batch-resolve multiple threads
+
+Use GraphQL aliases to resolve several threads in one request:
+
+```graphql
+mutation {
+  t1: resolveReviewThread(input: {threadId: "THREAD_ID_1"}) {
+    thread { isResolved }
+  }
+  t2: resolveReviewThread(input: {threadId: "THREAD_ID_2"}) {
+    thread { isResolved }
+  }
+  t3: resolveReviewThread(input: {threadId: "THREAD_ID_3"}) {
+    thread { isResolved }
+  }
+}
+```
+
+## Fetch PR details (REST)
+
+```bash
+gh pr view <PR_NUMBER> --json title,body,state,reviews,comments,headRefName,statusCheckRollup
+```
+
+## Fetch inline review comments (REST)
+
+```bash
+OWNER_REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+gh api "repos/$OWNER_REPO/pulls/<PR_NUMBER>/comments"
+```
+
+## Fetch general PR comments edited in place (REST)
+
+General PR comments are issue comments. Greptile may update one summary comment repeatedly, so select by `updated_at` instead of `created_at`:
+
+```bash
+OWNER_REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+gh api --paginate "repos/$OWNER_REPO/issues/<PR_NUMBER>/comments?per_page=100" \
+  | jq -s 'add
+    | map(select(.user.login | test("greptile"; "i")))
+    | sort_by(.updated_at)
+    | last
+    | {author: .user.login, updated_at, body}'
+```
