Verify MEGA — $ARGUMENTS

Overview

Run all 5 MEGA Close Gates on a ticket (or audit all recently-closed MEGAs). Prevents false Dones on multi-phase tickets.

Mode Detection

• If $ARGUMENTS is --all-done-7d: Audit mode — scan all MEGAs marked Done in last 7 days
• If $ARGUMENTS is CAB-XXXX: Single mode — verify one MEGA ticket

Step 1: Fetch MEGA Data

Single Mode

linear.get_issue("CAB-XXXX", includeRelations=true)

Extract:

• title — verify contains [MEGA] or has children
• children.nodes[] — list of sub-tickets with id, identifier, state.name, estimate
• estimate — total points

If no children → report: "CAB-XXXX is not a MEGA (no children). Use standard close flow."

Audit Mode

linear.list_issues(
  teamId: "<LINEAR_TEAM_ID>",
  filter: { state: { name: { eq: "Done" } }, updatedAt: { gte: "<7 days ago>" } }
)

Filter results to only MEGAs (title contains [MEGA] or has children). Run gates on each.

Step 2: Gate 0 — Decomposition Invariant

• Check: children.nodes.length > 0
• Pass: MEGA has sub-tickets
• Fail: "MEGA has no sub-tickets. Run /decompose CAB-XXXX first."

Step 3: Gate 1 — Per-Phase PR Evidence

For each child ticket in Done state:

linear.list_comments(issueId: "<child_id>")

Check that at least one comment contains PR # or PR [#.

• Pass: All Done children have PR evidence
• Fail: List children missing PR references: "CAB-XXXX: no PR evidence found"

Step 4: Gate 2 — All Sub-Tickets Done

Check each child's state.name:

• Pass: ALL children have state.name == "Done" or state.name == "Canceled"
• Fail: List non-Done children with their current state:

  CAB-1351: In Progress
  CAB-1352: Todo

Step 5: Gate 3 — Live Verification

Based on the MEGA's component scope:

• API changes: curl -s https://api.gostoa.dev/health → expect 200
• UI/Portal: curl -s https://console.gostoa.dev or curl -s https://portal.gostoa.dev → expect 200
• Gateway: curl -s https://mcp.gostoa.dev/health → expect 200
• Docs: curl -s https://docs.gostoa.dev → expect 200
• Cross-component: verify all affected endpoints

If automated verification is not possible, prompt the user: "Gate 3 requires manual verification. Please confirm the target is working: [endpoint/site]"

Step 6: Gate 4 — No Stale Children

Check no child is stuck in non-terminal state:

• Pass: Zero children in "In Progress", "Todo", or "Blocked"
• Fail: List stale children (these should be either Done or explicitly descoped)

Step 7: Render Verdict

Format

## MEGA Verification: CAB-XXXX — [Title]

| # | Gate | Status | Detail |
|---|------|--------|--------|
| 0 | Decomposition | ✅/❌ | N sub-tickets |
| 1 | PR Evidence | ✅/❌ | N/M children have PRs |
| 2 | All Done | ✅/❌ | N/M children Done |
| 3 | Live Verification | ✅/❌ | endpoint status |
| 4 | No Stale Children | ✅/❌ | N stale |

**Verdict**: Go / Fix

If Go (all gates pass)

1. Mark parent MEGA as Done on Linear:

   linear.update_issue(id, state="Done")

2. Post comprehensive completion comment:

   linear.create_comment(issueId, body="MEGA completed — all 5 gates passed.\n\nSub-tickets:\n- CAB-1350: Done (PR #578)\n- CAB-1351: Done (PR #582)\n- CAB-1352: Done (PR #590)\n\nLive verification: ✅ [endpoint] responding")

3. Log: MEGA-GATE-PASS | task=CAB-XXXX gates=5/5

If Fix (any gate fails)

1. Keep parent MEGA In Progress (do NOT mark Done)
2. Post audit comment listing gaps:

   linear.create_comment(issueId, body="MEGA verification failed — X/5 gates passed.\n\nFailing gates:\n- Gate 1: CAB-1352 missing PR evidence\n- Gate 2: CAB-1352 still In Progress\n\nAction required: complete remaining work before closing.")

3. Log: MEGA-GATE-FAIL | task=CAB-XXXX missing=<gate_numbers>
4. List remediation steps for each failing gate
