Verify a candidate PR

Review the packet, the candidate diff, and relevant tests. Live comparison against a captured baseline is optional. No edits, no merges, no pushes.

1. Resolve the PR and its linked issue

PR=$(echo "$ARGUMENTS" | sed -E 's|.*/||; s|#||g' | grep -oE '^[0-9]+' | head -1)
[ -z "$PR" ] && { echo "Invalid input: '$ARGUMENTS'. Pass a PR number or URL." >&2; exit 1; }
REPO=stickerdaniel/linkedin-mcp-server

gh pr view $PR --repo $REPO --json title,body,baseRefName,headRefName,headRepositoryOwner,mergeable,mergeStateStatus,additions,deletions,changedFiles,maintainerCanModify,statusCheckRollup

Extract the linked issue number from the PR body (Closes #, Fixes #, Resolves #, or plain #N). Call it ISSUE. If multiple, ask which one is the verification target.

Read that issue's packet and comments.

2. Packet, diff, and tests

This path does not need /tmp/repro-issue-$ISSUE-main.json. Absence of a local baseline limits the live branch, not the whole PR verdict. Do not create fake success or failure files.

gh pr diff $PR --repo $REPO
gh pr view $PR --repo $REPO --json files --jq '.files[].path'

Hard flags (any one downgrades a clean live pass to concerns):

  • Locale-dependent detection: == "Connect", in ["Pending", "Follow"], contains("1st"), aria-label="..." with translated text. Attribute presence is the locale-independent signal.
  • LinkedIn class-name selectors: .entity-result__item, .artdeco-button__text. Minimal generic selectors only (a[href*="/jobs/view/"]).
  • Multiple navigations behind one PERSON_SECTIONS / COMPANY_SECTIONS entry.
  • Missing tests beside the canonical owner from docs/scraping-architecture.md.

A supplied capture or regression fixture can support a before-and-after claim within its scope. Protocol or startup failures are execution limits, not a pass.

This step is complete when the report can say whether the diff addresses the packet at this SHA, which audit flags apply, and whether a live comparison is still needed.

3. Optional live comparison

Only after an explicit yes, and only when a genuine captured baseline exists.

/2-repro-issue writes:

  • /tmp/repro-issue-<ISSUE>-main.json. Captured response
  • /tmp/repro-issue-<ISSUE>-meta.json. {tool, arguments, sha}

If either file is missing or empty, keep the packet-and-diff verdict. Offer the evidence-and-code path. A new live baseline requires approval.

Read sha from the meta file. Do not claim an on-main baseline merely because of the filename. Compare the same call and a sufficiently comparable account context before claiming a live fix.

if [ ! -s /tmp/repro-issue-$ISSUE-main.json ] || [ ! -s /tmp/repro-issue-$ISSUE-meta.json ]; then
  echo "No captured baseline. Keep the packet-and-diff verdict. Do not check out or call the server." >&2
  exit 0
fi
TOOL=$(jq -r .tool /tmp/repro-issue-$ISSUE-meta.json)
ARGS_JSON=$(jq -c .arguments /tmp/repro-issue-$ISSUE-meta.json)
BASE_SHA=$(jq -r .sha /tmp/repro-issue-$ISSUE-meta.json)
echo "Replaying: $TOOL($ARGS_JSON) from sha $BASE_SHA"

Guarded checkout. Leave the user's original branch or detached SHA intact. Clean up only processes and files this run created.

if [ -n "$(git status --porcelain)" ]; then
  echo "Worktree is dirty. Ask before checkout. Do not continue live comparison on a dirty tree." >&2
  exit 1
fi
CURRENT_REF=$(git symbolic-ref -q --short HEAD || git rev-parse HEAD)

git fetch origin "pull/$PR/head" || { echo "git fetch for PR #$PR failed, aborting before checkout." >&2; exit 1; }
PR_SHA=$(git rev-parse FETCH_HEAD)
git checkout --detach "$PR_SHA"

cleanup_verify() {
  rc=$?
  trap - EXIT INT TERM
  kill $SERVER_PID 2>/dev/null
  wait $SERVER_PID 2>/dev/null
  git checkout "$CURRENT_REF" 2>/dev/null
  rm -f /tmp/verify-pr-$PR.json /tmp/verify-pr-$PR-headers /tmp/verify-pr-$PR.log /tmp/verify-pr-$PR-init.json /tmp/verify-pr-$PR-initialized.json
  exit $rc
}
trap cleanup_verify EXIT INT TERM

Restart the server after checkout.

Capture and inspect both response bodies before tools/call. A protocol or validation error is an execution limit.

  -H "Accept: application/json, text/event-stream" \

Live outcomes: fixes in this environment, fixes with concerns, does not fix in this environment, execution limit. A success here never refutes a reporter failure on a different account.

4. Report

**PR #<PR>** (linked #<ISSUE>). <one-line PR title>
**Mergeable:** <CLEAN | DIRTY conflicts | BLOCKED>
**Scope:** <+X/-Y, N files>
**Packet/diff verdict:** <addresses the packet | does not address the packet | needs more evidence>
**Live verdict:** <optional, or skipped: no baseline>
**Audit flags:** <locale-dependent | DOM-class selectors | section-mapping violation | missing tests | none>
**Recommended next step:** <merge | request changes | take over via maintainer-edits | no live check needed>

Non-negotiables

  • Packet and diff first. Live comparison only after yes, with a genuine baseline.
  • Restart the server after checkout. Running workers hold stale code.
  • Do not push, edit the PR, or merge.
  • Leave the user's original branch or detached SHA intact.
  • Locale and DOM-class flags remain concerns even if a live call looks fixed on one target.
