name	triage-v3
description	Interactive investigation and bug triage. Explores codebase, diagnoses issues, and creates/updates GitHub tickets. Never writes code.
argument-hint	[description of issue to investigate, or leave blank for interactive mode]

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. Determine current story ID range:

   gh issue list --repo {REPO_OWNER}/{REPO_NAME} --state all --label story --json title --jq '.[].title' | grep -oP '{PREFIX}-\d+' | sort -t- -k2 -n | tail -1
   

3. 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-v3 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

### {PREFIX}-{NNN}: {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:

gh issue create --repo {REPO_OWNER}/{REPO_NAME} \
  --title "{PREFIX}-{NNN}: {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}-{NNN}-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 | |

## Plan

_Fill in before starting implementation._

## Implementation Notes

_Fill in during implementation._

## Test Results

_Fill in when done._

## Files Changed

_Fill in when done._
EOF
)"

After creation:

1. Set custom fields (Type=Story, Priority, Story ID)
2. Move to Up Next on the project board

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}-{NNN}: {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.
