Toolkit Validation

Validate frontmatter metadata across workspace files.

What This Does

Checks frontmatter in:

• •Handovers (sessions/*.md)
• •Plans (plans/*.md)

Validates:

• •Required fields are present
• •Field naming follows snake_case convention
• •Date formats are YYYY-MM-DD
• •Status values are valid
• •File naming follows YYYY-MM-DD-* pattern

Validation Philosophy: Frictionless

Hard Stop (Exit 1):

• •Missing required fields (session_id, plan_id, etc.)
• •Invalid field names (camelCase, PascalCase when snake_case required)
• •Malformed frontmatter structure

Suggestions Only (Exit 0):

• •Missing optional fields
• •Recommendations for improvement
• •Best practice reminders

Goal: Catch critical errors without blocking workflow for stylistic preferences.

When to Use

• •Before archiving handovers
• •Before graduating plans
• •During code reviews
• •As part of CI/CD checks
• •When teaching Toolkit conventions

Usage

# Validate all workspace files
/toolkit-validate

# Validate specific file
/toolkit-validate sessions/2026-02-01-feature.md

# Dry run (show what would be checked)
/toolkit-validate --dry-run

What Gets Checked

Handover Files (sessions/*.md)

Required Fields:

• •session_id (string, matches filename pattern)
• •context (string)
• •status (enum: draft|in_progress|paused|completed)
• •last_updated (YYYY-MM-DD)

Optional Fields:

• •previous_session (string)
• •continued_in (string)
• •blockers (array)
• •next_steps (array)
• •related_files (array)

Plan Files (plans/*.md)

Required Fields:

• •plan_id (string, matches filename pattern)
• •status (enum: draft|in_progress|decided|archived)
• •last_updated (YYYY-MM-DD)

Optional Fields:

• •related_to (string)
• •decision (string)

Script Files (*.sh)

Required in Comments:

• •Script name
• •Purpose description
• •Created date (YYYY-MM-DD)

Optional:

• •Author
• •Status

Implementation

When invoked, this skill runs the scripts/validate-frontmatter.sh script included as an asset in this directory.

The validator:

1. •Scans target files
2. •Extracts frontmatter
3. •Validates required fields
4. •Checks field naming conventions
5. •Verifies date formats
6. •Reports errors and suggestions
7. •Exits with appropriate status code

Example Output

🔍 Validating Toolkit workspace files...

✓ sessions/2026-02-01-feature.md
  All required fields present

✗ sessions/2026-02-02-bug-fix.md
  ERROR: Missing required field 'session_id'

⚠ plans/2026-02-03-design.md
  SUGGESTION: Consider adding 'decision' field for clarity

Summary: 2 valid, 1 error, 1 suggestion
