Task Validation Loop

If the user selects "Cancel — I'll switch first": output the switching commands above and stop. Do not proceed with the skill.

Step 0: Resolve Project Context

Before loading specs, ensure project context is resolved:

1. Monorepo check: Does .groundwork.yml exist at the repo root?
   • If yes → Is {{project_name}} non-empty?
     • If empty → Invoke Skill(skill="groundwork:project-selector") to select a project, then restart this skill.
     • If set → Project is {{project_name}}, specs at {{specs_dir}}/.
   • If no → Continue (single-project repo).
2. CWD mismatch check (monorepo only):
   • Skip if not in monorepo mode or if the project was just selected in item 1 above.
   • If CWD is the repo root → fine, proceed.
   • Check which project's path CWD falls inside (compare against all projects in .groundwork.yml).
   • If CWD is inside the selected project's path → fine, proceed.
   • If CWD is inside a different project's path → warn via AskUserQuestion:

     "You're working from <cwd> (inside [cwd-project]), but the selected Groundwork project is [selected-project] ([selected-project-path]/). What would you like to do?"

     • "Switch to [cwd-project]"
     • "Stay with [selected-project]" If the user switches, invoke Skill(skill="groundwork:project-selector").

   • If CWD doesn't match any project → proceed without warning (shared directory).
3. Proceed with the resolved project context. All {{specs_dir}}/ paths will resolve to the correct location.

Prerequisites

Before invoking this skill, ensure:

• Task list is complete ({{specs_dir}}/tasks/ directory or {{specs_dir}}/tasks.md exists)
• PRD exists ({{specs_dir}}/product_specs.md)
• Architecture exists ({{specs_dir}}/architecture.md)
• User has approved the task breakdown

Workflow

1. Gather Context

Collect inputs for the agents:

task_list     ← Read {{specs_dir}}/tasks.md (or {{specs_dir}}/tasks/ directory)
product_specs ← Read {{specs_dir}}/product_specs.md (or {{specs_dir}}/product_specs/ directory)
architecture  ← Read {{specs_dir}}/architecture.md (or {{specs_dir}}/architecture/ directory)
design_system ← Read {{specs_dir}}/design_system.md (if exists, optional)

Detection: Check for file first (takes precedence), then directory. When reading a directory, aggregate all .md files recursively.

1.5. Determine Active Agents

prd-task-alignment-checker and architecture-task-alignment-checker always run (their inputs are prerequisites).

Record skipped agents with verdict skipped.

2. Launch Validation Agents

Use Agent tool to launch all 3 agents in parallel:

Each returns JSON:

{
  "summary": "One-sentence assessment",
  "score": 0-100,
  "findings": [{"severity": "critical|major|minor", "category": "...", "task_reference": "TASK-NNN", "finding": "...", "recommendation": "..."}],
  "verdict": "approve|request-changes"
}

3. Aggregate Results

Present results in table format:

## Task List Validation Report

| Agent | Score | Verdict | Critical | Major | Minor |
|-------|-------|---------|----------|-------|-------|
| PRD Alignment | 92 | approve | 0 | 1 | 2 |
| Architecture Alignment | 88 | approve | 0 | 1 | 1 |
| Design Alignment | 85 | approve | 0 | 2 | 1 |

**Overall:** PASS / NEEDS FIXES

4. Autonomous Fix-and-Retry Loop

Rule: Continue this loop until ALL agents return approve.

On any request-changes verdict:

1. Log Iteration

   ## Validation Iteration [N]
   | Agent | Verdict | Findings |
   |-------|---------|----------|
   | ... | ... | ... |
   Fixing [X] issues...
   

2. Fix Each Finding - Apply each critical/major recommendation

   • Modify the relevant task file in {{specs_dir}}/tasks/ (or {{specs_dir}}/tasks.md if single-file)
   • Track what was changed
   • Note which finding each fix addresses

   Fix types:

   • requirement-not-tasked: Add new task for the requirement
   • component-mismatch: Update task's Component field
   • accessibility-missing: Add acceptance criteria to task
   • over-tasked: Remove task or add requirement to PRD (user decision)

3. Re-run Agent Validation — Re-launch ONLY agents that returned request-changes. Agents that approved retain their verdict unless the fix changed content in their domain:

   • PRD alignment checker: re-run if tasks were added/removed or requirements mapping changed
   • Architecture alignment checker: re-run if component assignments or technology references changed
   • Design alignment checker: re-run if accessibility criteria or design token references changed

   For agents NOT re-run, carry forward their previous approve verdict and score.

4. Check Results

   • ALL approve → PASS, return success
   • Any request-changes → Return to step 1

5. Stuck Detection

Track findings by key: [Agent]-[Category]-[TaskRef]

If same finding appears 3 times:

## Stuck - Need User Input

Issue persists after 3 attempts:

**[Agent] Finding description**
- Task: TASK-NNN
- Category: [category]
- Attempts:
  1. [what was tried]
  2. [what was tried]
  3. [what was tried]

I need clarification: [specific question]

• Use AskUserQuestion for guidance
• Apply fix based on user input
• Continue loop

Also escalate when:

• Conflicting requirements between PRD and architecture
• Missing information to create required task
• Scope decisions needed (add to PRD vs. remove task)

6. Return Result

On PASS:

## Task List Validation PASSED

All 3 agents approved after [N] iteration(s).

| Agent | Score | Verdict | Summary |
|-------|-------|---------|---------|
| PRD Alignment | 95 | APPROVE | All requirements covered |
| Architecture Alignment | 92 | APPROVE | Tasks follow architecture |
| Design Alignment | 90 | APPROVE | UI tasks include a11y |

Issues fixed:
- [Iteration N] Agent: Description

Coverage Summary:
- PRD Requirements: [X]% covered
- Architecture Components: All referenced
- Design System: [Applied/N/A]

Minor suggestions (optional):
- ...

Return control to calling skill (tasks skill).

Severity Reference

Edge Cases

No design system:

• Design agent still runs (checks accessibility)
• Note in summary: "Design system not found"

Agent returns error:

• Log the error
• Retry once
• If still fails, escalate to user

All agents approve immediately:

• Log success
• Return without iteration
