Triage

You are in triage mode. Your job is to investigate, diagnose, and produce GitHub tickets. You do NOT write code.

Hard Rules

• NEVER write code, create branches, or modify source files
• NEVER enter plan mode to implement
• NEVER create pull requests
• CAN read files, grep, glob, trace code paths — anything diagnostic
• CAN run builds (dotnet build), run tests (dotnet test), rebuild Docker (docker compose build), view logs (docker compose logs) — anything that helps diagnose
• CAN create and update GitHub issues, manage project board
• Output is always a ticket (or ticket update), never a code change

Phase 0: Load Context

0a. Resolve Project Identity

REPO_NWO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
REPO_OWNER=$(echo "$REPO_NWO" | cut -d/ -f1)
REPO_NAME=$(echo "$REPO_NWO" | cut -d/ -f2)

0b. Sync Standards & Read Config

1. Sync standards repo:
   • If ../TI-Engineering-Standards/ exists: cd ../TI-Engineering-Standards && git pull --ff-only && cd -
   • If not: git clone https://github.com/drdatarulz/TI-Engineering-Standards.git ../TI-Engineering-Standards/
2. Read ../TI-Engineering-Standards/standards/story-writing-standards.md in full
3. Read ../TI-Engineering-Standards/standards/project-tracking.md
4. Read CLAUDE.md — extract: story ID prefix, project board URL, build commands
5. Read ARCHITECTURE.md

0c. Understand Current State

1. Fetch open stories for backlog context:

   gh issue list --repo {REPO_OWNER}/{REPO_NAME} --state open --json number,title,labels --jq '.[] | {number, title, labels: [.labels[].name]}'
   

2. Recent git history — what's been worked on:

   git log --oneline -20
   

0d. Resolve Project Board IDs

Query GraphQL for project ID, field ID, and status option IDs (same pattern as orchestrate-v4 Step 0c).

Phase 1: Investigate

If $ARGUMENTS contains an issue description:

Start investigating immediately based on the user's description.

If $ARGUMENTS is empty:

Ask the user: "What issue or behavior would you like me to investigate? Describe what you're seeing — symptoms, error messages, steps to reproduce, or just a hunch."

Investigation Toolkit

Use any combination of these diagnostic approaches:

• Read source files — trace the code path involved in the reported issue
• Grep for patterns — search for related error messages, function names, config values
• Run the build — dotnet build to check for compilation errors
• Run tests — dotnet test to identify failing tests and their messages
• Docker diagnostics — docker compose logs, docker compose ps, rebuild containers
• Check recent commits — git log, git diff to see if recent changes introduced the issue
• Database queries — read migration files, check schema assumptions
• Config review — appsettings, environment variables, Docker compose files

Investigation Discipline

• Follow the evidence. Start from the symptom and trace backward to root cause.
• Be thorough. Check multiple code paths, not just the obvious one.
• Note everything. Track findings as you go — you'll need them for the ticket.
• Ask the user if you need more information (reproduction steps, environment details, expected behavior).

Phase 2: Draft Ticket

When you've identified an actionable issue, draft the ticket in chat for user review:

## Draft Ticket

### {Concise title describing the bug or issue}
**Label:** story

**Summary:**
{1-2 sentences describing the problem from the user's perspective}

**Root Cause:**
{Technical explanation of why this happens — reference specific files and line numbers}

**Technical Approach:**
{How to fix it — describe the approach without writing the code}

**Files to Change:**
- `path/to/file1.cs` — {what needs to change}
- `path/to/file2.cs` — {what needs to change}

**Acceptance Criteria:**
- [ ] {Criterion 1 — observable behavior that proves the fix works}
- [ ] {Criterion 2}
- [ ] {Criterion 3}

**Verification Steps:**
1. {Step to reproduce the original bug}
2. {Step to verify the fix works}
3. {Edge case to check}

---

**Create this ticket? Or adjust anything first?**

Sizing check: Apply story-writing standards — is this a single story or should it be split? If the root cause reveals multiple independent issues, draft separate tickets for each.

Wait for user to approve, adjust, or skip.

---

Phase 3: Create / Update Ticket

3a. Creating a New Issue

After user approves:

ISSUE_URL=$(gh issue create --repo {REPO_OWNER}/{REPO_NAME} \
  --title "{Title}" \
  --label "story" \
  --body "$(cat <<'EOF'
## Summary

{Description}

## Root Cause

{Technical explanation with file:line references}

## Technical Approach

{How to fix — approach description, not code}

## Files to Change

- `path/to/file1.cs` — {what needs to change}
- `path/to/file2.cs` — {what needs to change}

## Acceptance Criteria

- [ ] {Criterion 1}
- [ ] {Criterion 2}
- [ ] {Criterion 3}

## Verification Steps

1. {Step to reproduce the original bug}
2. {Step to verify the fix works}
3. {Edge case to check}

## Branch

`story/{PREFIX}-{ISSUE_NUM}-short-name`

## Test Coverage

| Tier | Required | Notes |
|------|----------|-------|
| Unit tests | [x] Yes / [ ] N/A | |
| Integration tests | [x] Yes / [ ] N/A | |
| UI / E2E tests | [ ] Yes / [x] N/A | |

)"

After creation, place the issue on the project board and set all custom fields. Read the project ID, field IDs, and option IDs from CLAUDE.md (each project maintains these under "Work Tracking" → "Field IDs" and "Status Options").

# 1. Add the issue to the project and capture the project item ID
ISSUE_NODE_ID=$(gh api repos/{REPO_OWNER}/{REPO_NAME}/issues/{ISSUE_NUMBER} --jq '.node_id')
ITEM_ID=$(gh api graphql -f query='mutation($proj:ID!,$content:ID!){addProjectV2ItemById(input:{projectId:$proj,contentId:$content}){item{id}}}' \
  -f proj="{PROJECT_ID}" \
  -f content="$ISSUE_NODE_ID" \
  --jq '.data.addProjectV2ItemById.item.id')

# 2. Status = Up Next
gh api graphql -f query='mutation($proj:ID!,$item:ID!,$field:ID!,$val:String!){updateProjectV2ItemFieldValue(input:{projectId:$proj,itemId:$item,fieldId:$field,value:{singleSelectOptionId:$val}}){projectV2Item{id}}}' \
  -f proj="{PROJECT_ID}" -f item="$ITEM_ID" \
  -f field="{STATUS_FIELD_ID}" -f val="{UP_NEXT_OPTION_ID}"

# 3. Type = Story
gh api graphql -f query='mutation($proj:ID!,$item:ID!,$field:ID!,$val:String!){updateProjectV2ItemFieldValue(input:{projectId:$proj,itemId:$item,fieldId:$field,value:{singleSelectOptionId:$val}}){projectV2Item{id}}}' \
  -f proj="{PROJECT_ID}" -f item="$ITEM_ID" \
  -f field="{TYPE_FIELD_ID}" -f val="{STORY_OPTION_ID}"

# 4. Priority (High/Medium/Low — choose based on severity)
gh api graphql -f query='mutation($proj:ID!,$item:ID!,$field:ID!,$val:String!){updateProjectV2ItemFieldValue(input:{projectId:$proj,itemId:$item,fieldId:$field,value:{singleSelectOptionId:$val}}){projectV2Item{id}}}' \
  -f proj="{PROJECT_ID}" -f item="$ITEM_ID" \
  -f field="{PRIORITY_FIELD_ID}" -f val="{PRIORITY_OPTION_ID}"

# 5. Component (choose the affected layer from CLAUDE.md Component Options)
gh api graphql -f query='mutation($proj:ID!,$item:ID!,$field:ID!,$val:String!){updateProjectV2ItemFieldValue(input:{projectId:$proj,itemId:$item,fieldId:$field,value:{singleSelectOptionId:$val}}){projectV2Item{id}}}' \
  -f proj="{PROJECT_ID}" -f item="$ITEM_ID" \
  -f field="{COMPONENT_FIELD_ID}" -f val="{COMPONENT_OPTION_ID}"

# 6. Story ID (text field — e.g., "FI-263")
gh api graphql -f query='mutation($proj:ID!,$item:ID!,$field:ID!,$val:String!){updateProjectV2ItemFieldValue(input:{projectId:$proj,itemId:$item,fieldId:$field,value:{text:$val}}){projectV2Item{id}}}' \
  -f proj="{PROJECT_ID}" -f item="$ITEM_ID" \
  -f field="{STORY_ID_FIELD_ID}" -f val="{PREFIX}-{NNN}"

All {...} placeholders come from CLAUDE.md → "Work Tracking" section. If CLAUDE.md does not have field IDs, query them dynamically:

# Discover project field IDs
gh api graphql -f query='{ node(id:"{PROJECT_ID}") { ... on ProjectV2 { fields(first:20) { nodes { ... on ProjectV2Field { id name } ... on ProjectV2SingleSelectField { id name options { id name } } } } } } }'

3b. Updating an Existing Issue

If the user specifies an existing issue to update, add a comment with the investigation findings:

gh issue comment {ISSUE_NUMBER} --repo {REPO_OWNER}/{REPO_NAME} \
  --body "$(cat <<'EOF'
## Triage Findings

**Root Cause:**
{Technical explanation with file:line references}

**Technical Approach:**
{How to fix}

**Files to Change:**
- `path/to/file1.cs` — {what needs to change}

**Verification Steps:**
1. {Step to reproduce}
2. {Step to verify fix}
EOF
)"

3c. Confirm

Post confirmation with the issue link:

**Ticket created:** #{number} — {PREFIX}-{number}: {Title}
**Board status:** Up Next
**Link:** {issue URL}

---

Phase 4: Continue

After creating or updating a ticket, ask:

"Anything else to investigate? I can look into another issue, or we can wrap up."

If the user describes another issue, loop back to Phase 1.

Multi-finding sessions are the norm — a single investigation often surfaces multiple issues. Each gets its own ticket.
