Mpx Report Issue Or Bug

Report Issue or Bug

Track bugs and issues within the .mpx/ phase system. Parses bug reports, finds related phases, adds fix tasks to existing checklists or creates new bugfix phases.

Iron Law

DOCUMENTATION ONLY. This skill updates .mpx/ files (SPEC.md, ROADMAP.md, CHECKLIST.md). It NEVER modifies source code, configs, tests, or any non-.mpx/ file. No implementation. No code changes. No exceptions.

Usage

/mpx-report-issue-or-bug "Login form crashes when email contains + character"
/mpx-report-issue-or-bug "API returns 500 on empty payload"
/mpx-report-issue-or-bug   # Prompts for issue description

Prerequisites

• .mpx/SPEC.md must exist
• .mpx/ROADMAP.md must exist

Workflow

Step 1: Parse Issue

If issue provided as $ARGUMENTS, use it. If no argument, ask the user:

"Describe the bug or issue you want to track."

Extract from the description:

• Summary — one-line description
• Severity — critical / high / medium / low (default: medium)
• Affected area — component, feature, or module
• Reproduction steps — if provided

Step 2: Read MXP State

Read all relevant project files:

• .mpx/SPEC.md — Master requirements
• .mpx/ROADMAP.md — Phase overview + tracking
• .mpx/phases/*/CHECKLIST.md — Phase specs, tasks, and state

Note each phase's status (complete/incomplete), section headings, and scope.

Step 3: Find Related Sections

Keyword match the affected area against:

• Section headings in CHECKLIST.md files
• Task descriptions
• Scope items in each phase

Rank matches:

• Strong — direct keyword match in section heading or scope
• Weak — partial match in task descriptions
• None — no relevant match found

Step 4: Decide Placement

Use AskUserQuestion for weak-match decisions.

Step 5: Update Files

1. Update CHECKLIST.md (existing or new phase):

   • Add Fix: + Verify: task pair
   • Include severity tag in inline spec: [severity: high]
   • Fix: prefix distinguishes bug tasks from feature tasks

   Example tasks:

   - [ ] Fix: Login form crashes on emails with + character [severity: medium]
     > Email addresses containing + are valid per RFC 5321. The form validation regex rejects them incorrectly.
   - [ ] Verify: Login accepts emails with special characters (+, dots, hyphens)
   

2. Update ROADMAP.md:

• Update task counts/status for affected incomplete/blocked phase
• Keep completed phases as one-line records only
• Remove redundant completed-phase references unless required to explain an unblock dependency
• Add new bugfix phase entry when created

3. Update SPEC.md (critical/high severity only):

   • Add to ## Known Issues section (create section if missing)

4. New bugfix phase (when needed):

   • Naming: NN-bugfix-[area] (e.g., 04-bugfix-auth)
   • Create folder + CHECKLIST.md with standard structure
   • Add phase entry to ROADMAP.md

Step 6: Report

Issue Tracked Successfully!

Summary: [one-line description]
Severity: [severity]
Placement: [phase name] (new/existing)

Files Updated:
  - .mpx/phases/NN-name/CHECKLIST.md — Added fix + verify tasks
  - .mpx/ROADMAP.md — Updated task count
  - .mpx/SPEC.md — Added to Known Issues (if critical/high)

New Tasks:
  - [ ] Fix: [description]
  - [ ] Verify: [description]

Next: Run `/mp-execute mpx` to implement the fix.

Task Generation Rules

• Always generate a Fix + Verify task pair
• Fix: prefix marks bug-related tasks (vs feature tasks)
• Verify task confirms the fix works and doesn't regress
• Follow existing task style in the project
• Include severity tag inline: [severity: level]

Error Handling

• No SPEC.md: "No project found. Run /mpx-setup first."
• Empty description: "Please describe the bug or issue to track."
• Ambiguous area: Use AskUserQuestion to clarify affected component

Notes

• This skill modifies project files — changes can be reviewed with git diff
• Bug tasks use Fix: prefix to distinguish from feature tasks
• Critical/high issues are surfaced in SPEC.md Known Issues for visibility
• Completed phases are never reopened — new bugfix phase created instead
• ROADMAP concision policy: completed phase = one line; detailed status belongs to incomplete/blocked phases
