This skill creates task management documentation: docs/tasks/README.md (task management system rules) and docs/tasks/kanban_board.md (Linear integration with Epic Story Counters).

When to Use This Skill

This skill is a L2 WORKER invoked by ln-100-documents-pipeline orchestrator OR used standalone.

Use this skill when:

Creating task management documentation (docs/tasks/)
Setting up Linear integration and kanban board
Validating existing task documentation structure and content
Configuring Linear team settings (Team Name, UUID, Key)

Part of workflow: ln-100-documents-pipeline → ln-110-project-docs-coordinator → ln-120-reference-docs-creator → ln-130-tasks-docs-creator → ln-140-test-docs-creator (optional) → ln-150-presentation-creator

How It Works

The skill follows a 3-phase workflow: CREATE → VALIDATE STRUCTURE → VALIDATE CONTENT.

Phase 1: CREATE - Create tasks/README.md from template with SCOPE tags, workflow rules, Linear integration Phase 2: VALIDATE STRUCTURE - Auto-fix structural violations (SCOPE tags, sections, Maintenance, POSIX) Phase 3: VALIDATE CONTENT - Validate semantic content + special Linear Configuration handling (placeholder detection, UUID/Team Key validation, interactive user prompts)

Phase 1: Create tasks/README.md

Objective: Create task management system documentation from template.

When to execute: Always (first phase)

Process:

Check if tasks/README.md exists:

Use Glob tool: pattern: "docs/tasks/README.md"

If file exists:

Skip creation

Log: ✓ docs/tasks/README.md already exists (preserved)
Proceed to Phase 2
If NOT exists:

Continue to step 2

Create tasks directory:

Create the docs/tasks/ directory if it doesn't exist

Create tasks/README.md from template:

Copy template: references/tasks_readme_template.md (v2.0.0) → docs/tasks/README.md

Replace placeholders:

{{DATE}} → current date (YYYY-MM-DD)

Template contains:

SCOPE tags: 

Story-Level Test Task Pattern
Kanban Board Structure (Epic Grouping Pattern)
Linear Integration (MCP methods)
Maintenance section
Notify user:

If created: ✓ Created docs/tasks/README.md with task management rules

If skipped: ✓ docs/tasks/README.md already exists (preserved)

Output: docs/tasks/README.md (created or existing)

Phase 2: Validate Structure

Objective: Ensure tasks/README.md and kanban_board.md comply with structural requirements. Auto-fix violations.

When to execute: After Phase 1 completes (files exist or created)

Process:

2.1 Validate SCOPE tags

Files to check: docs/tasks/README.md, docs/tasks/kanban_board.md (if exists)

For each file:

Read first 5 lines
Check for  tag
Expected values:

tasks/README.md: 

kanban_board.md: 
If missing:

Use Edit tool to add SCOPE tag after first heading

Log: ⚠ Auto-fixed: Added missing SCOPE tag to {filename}

2.2 Validate required sections

Load validation spec:

Read references/questions.md
Extract section names from questions

For tasks/README.md:

Required sections (from questions.md):

"Linear Integration" OR "Core Concepts" (Linear MCP methods)

"Task Workflow" OR "Critical Rules" (state transitions)
"Task Templates" (template references)
For each section:

Check if section header exists (case-insensitive)

If missing:

Use Edit tool to add section with placeholder content

Log: ⚠ Auto-fixed: Added missing section '{section}' to tasks/README.md

For kanban_board.md (if exists):

Required sections:

"Linear Configuration" (Team Name, UUID, Key)

"Work in Progress" OR "Epic Tracking" (Kanban sections)
For each section:

Check if section header exists

If missing:

Use Edit tool to add section with placeholder

Log: ⚠ Auto-fixed: Added missing section '{section}' to kanban_board.md

2.3 Validate Maintenance section

Files to check: docs/tasks/README.md, docs/tasks/kanban_board.md (if exists)

For each file:

Search for ## Maintenance header in last 20 lines
If missing:

Use Edit tool to add at end of file:

## Maintenance

**Update Triggers:**
- When Linear workflow changes
- When task templates are added/modified
- When label taxonomy changes

**Last Updated:** {current_date}

Log: ⚠ Auto-fixed: Added Maintenance section to {filename}

2.4 Validate POSIX line endings

Files to check: docs/tasks/README.md, docs/tasks/kanban_board.md (if exists)

For each file:

Check if file ends with single newline character
If missing:

Use Edit tool to add final newline

Log: ⚠ Auto-fixed: Added POSIX newline to {filename}

2.5 Report validation summary

Log summary:

✓ Structure validation completed:
  tasks/README.md:
    - SCOPE tag: [added/present]
    - Required sections: [count] sections [added/present]
    - Maintenance section: [added/present]
    - POSIX endings: [fixed/compliant]
  kanban_board.md:
    - SCOPE tag: [added/present/skipped - file not exists]
    - Required sections: [count] sections [added/present/skipped]
    - Maintenance section: [added/present/skipped]
    - POSIX endings: [fixed/compliant/skipped]

If violations found: ⚠ Auto-fixed {total} structural violations

Output: Structurally valid task management documentation

Phase 3: Validate Content

Objective: Ensure each section answers its validation questions with meaningful content. Special handling for Linear Configuration (placeholder detection, user prompts, UUID/Team Key validation).

When to execute: After Phase 2 completes (structure valid, auto-fixes applied)

Process:

3.1 Load validation spec

Read references/questions.md
Parse document sections and questions
Extract validation heuristics for each section

3.2 Validate kanban_board.md → Linear Configuration (Special Handling)

Question: "What is the Linear team configuration?"

Step 3.2.1: Check if kanban_board.md exists:

Use Glob tool: pattern: "docs/tasks/kanban_board.md"
If NOT exists:

Log: ℹ kanban_board.md not found - skipping Linear Configuration validation

Skip to Step 3.3
If exists:

Continue to Step 3.2.2

Step 3.2.2: Read Linear Configuration section:

Read docs/tasks/kanban_board.md
Locate ## Linear Configuration section
Extract Team Name, Team UUID, Team Key values

Step 3.2.3: Placeholder Detection:

Check for placeholders:

Pattern: [TEAM_NAME], [TEAM_UUID], [TEAM_KEY]
If ANY placeholder present → Interactive Setup Mode
If NO placeholders present → Validation Mode

Interactive Setup Mode (if placeholders detected):

Prompt user for Team Name:

Question: "What is your Linear Team Name?"

Validation: Non-empty string
Example: "My Project Team"
Prompt user for Team UUID:

Question: "What is your Linear Team UUID?"

Format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Validation Regex: /^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/
If invalid:

Show error: "Invalid UUID format. Expected: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (lowercase hex)"

Re-prompt user
Example: "a1b2c3d4-e5f6-7890-abcd-ef1234567890"
Prompt user for Team Key:

Question: "What is your Linear Team Key (2-4 uppercase letters)?"

Format: 2-4 uppercase letters
Validation Regex: /^[A-Z]{2,4}$/
If invalid:

Show error: "Invalid Team Key format. Expected: 2-4 uppercase letters (e.g., PROJ, WEB, API)"

Re-prompt user
Example: "PROJ"
Replace placeholders:

Use Edit tool to replace in kanban_board.md:

[TEAM_NAME] → {user_team_name}

[TEAM_UUID] → {user_team_uuid}
[TEAM_KEY] → {user_team_key}
[WORKSPACE_URL] → https://linear.app/{workspace_slug} (if placeholder exists)
Set initial counters (if table exists):

Set "Next Epic Number" → 1

Set "Next Story Number" → 1
Update Last Updated date:

Replace [YYYY-MM-DD] → {current_date} in Maintenance section

Save updated kanban_board.md
Log success:

✓ Linear configuration updated:
  - Team Name: {user_team_name}
  - Team UUID: {user_team_uuid}
  - Team Key: {user_team_key}
  - Next Epic Number: 1
  - Next Story Number: 1

Validation Mode (if real values present, no placeholders):

Extract existing values:

Extract Team UUID from line matching: Team UUID: {value} or in table

Extract Team Key from line matching: Team Key: {value} or in table
Validate formats:

UUID: /^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/

Team Key: /^[A-Z]{2,4}$/
If validation fails:

⚠ Invalid format detected in Linear Configuration:
  - Team UUID: {uuid} (expected: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
  - Team Key: {key} (expected: 2-4 uppercase letters)

Fix manually or re-run skill to replace with correct values.

Mark as invalid but continue (don't block)

If validation passes:

✓ Linear Configuration valid (Team: {name}, UUID: {uuid}, Key: {key})

3.3 Validate tasks/README.md sections

Parametric loop for 3 questions (from questions.md):

For each question in:

"How is Linear integrated into the task management system?"
"What are the task state transitions and review criteria?"
"What task templates are available and how to use them?"

Validation process:

Extract validation heuristics from questions.md
Read corresponding section content from tasks/README.md
Check if ANY heuristic passes:

Contains keyword X → pass

Has pattern Y → pass
Length > N words → pass
If ANY passes → Section valid
If NONE passes → Log warning: ⚠ Section may be incomplete: {section_name}

Example validation (Question 1: Linear Integration):

Heuristics:
- Contains "Linear" or "MCP" → pass
- Mentions team ID or UUID → pass
- Has workflow states (Backlog, Todo, In Progress) → pass
- Length > 100 words → pass

Check content:
- ✓ Contains "Linear" → PASS
→ Section valid

No auto-discovery needed (workflow is standardized in template)

3.4 Validate kanban_board.md → Epic Tracking

Question: "Are Epics being tracked in the board?"

If kanban_board.md exists:

Validation heuristics:

- Has "Epic" or "Epics Overview" section header → pass
- Has table with columns: Epic, Name, Status, Progress → pass
- OR has placeholder: "No active epics" → pass
- Length > 20 words → pass

Action:

Read Epic Tracking or Epics Overview section
Check if ANY heuristic passes
If passes → valid
If none pass → log warning: ⚠ Epic Tracking section may be incomplete

If kanban_board.md does NOT exist:

Skip validation
Log: ℹ Epic Tracking validation skipped (kanban_board.md not found)

3.5 Report content validation summary

Log summary:

✓ Content validation completed:
  tasks/README.md:
    - ✓ Linear Integration: valid (contains "Linear", "MCP", workflow states)
    - ✓ Task Workflow: valid (contains state transitions)
    - ✓ Task Templates: valid (contains template references)
  kanban_board.md:
    - ✓ Linear Configuration: {status} (Team: {name}, UUID: {uuid}, Key: {key})
    - ✓ Epic Tracking: valid (table present or placeholder)

Output: Validated and potentially updated task management documentation with Linear configuration

Reference Files Used

Templates

Tasks README Template:

references/tasks_readme_template.md (v2.0.0) - Task management system rules with:

SCOPE tags (task management ONLY)

Story-Level Test Task Pattern (tests in final Story task, NOT scattered)
Kanban Board Structure (Epic Grouping Pattern with Status → Epic → Story → Tasks hierarchy)
Linear Integration (MCP methods: create_project, create_issue, update_issue, list_issues)
Maintenance section (Update Triggers, Verification, Last Updated)

Kanban Board Template:

references/kanban_board_template.md (v3.0.0) - Linear integration template with:

Linear Configuration table (Team Name, UUID, Key, Workspace URL)

Epic Story Counters table (Next Epic Number, Story counters per Epic)
Kanban sections: Backlog, Todo (✅ APPROVED), In Progress, To Review, To Rework, Done (Last 5 tasks), Postponed
Epic Grouping Pattern format (Epic header → 📖 Story → Task with indentation)
Placeholders for Epic/Story/Task entries

Validation Specification

questions.md:

references/questions.md (v1.0) - Validation questions for task management documentation:

5 sections (3 for tasks/README.md, 2 for kanban_board.md)

Question format: Question → Expected Content → Validation Heuristics → Auto-Discovery Hints → MCP Ref Hints
Special handling section for Linear Configuration (placeholder detection, UUID/Team Key validation)

Best Practices

Story-Level Test Task Pattern: Tests consolidated in final Story task, NOT scattered across implementation tasks
Epic Grouping Pattern: Epic context always visible, 0/2/4 space indentation (Epic → Story → Tasks)
Linear MCP: All task operations use Linear MCP methods (create_project, create_issue, update_issue)
SCOPE Tags: Include in first 3-5 lines of all documentation files
Idempotent: Can be invoked multiple times - checks file existence, preserves existing files, re-validates on each run

Documentation Standards

NO_CODE Rule: Task docs describe workflows, not implementations
Stack Adaptation: References must match project stack
Format Priority: Tables (states, transitions) > Lists > Text

Prerequisites

Orchestrator: ln-110-documents-pipeline (invokes this worker in Phase 3, Step 3.3)

Standalone usage: Creating task docs, re-validating, setting up Linear Configuration

Idempotent: Yes - checks file existence, re-validates, auto-fixes, updates Linear Configuration if placeholders detected
