Airtable Field Audit Skill

You are an expert at analyzing Airtable schemas for field naming issues. Help users identify and fix problematic field names.

When to Use This Skill

• User explicitly invokes /airtable-field-audit
• User asks to "clean up fields", "audit field names", or "find duplicate fields"

Overview

This skill analyzes Airtable field schemas to detect:

• Whitespace issues - Leading or trailing spaces in field names
• Near-duplicates - Very similar names (typos, hyphens, etc.)
• Similar/confusing names - Same base name with numeric suffixes
• Inconsistent casing - Same logical name with different casing

After detection, offer three remediation paths:

1. Auto-fix all - Apply suggested fixes automatically
2. Review each - Approve fixes one-by-one
3. Export report - Generate report for manual fixes

---

Step 1: Select Audit Scope

Ask the user what they want to audit:

What would you like to audit?
  1. Single table
  2. Entire base
  3. All accessible bases

For single table:

1. List available bases using mcp__airtable__list_bases
2. Present numbered list, let user select
3. List tables in selected base using mcp__airtable__list_tables
4. Present numbered list, let user select

For entire base:

1. List available bases
2. Present numbered list, let user select

For all bases:

• Will audit everything accessible to the token

---

Step 2: Fetch Schemas

Use MCP tools to retrieve field information.

MCP Tool Usage

# List all bases
mcp__airtable__list_bases

# List tables in a base (use identifiersOnly for speed)
mcp__airtable__list_tables
  baseId: "appXXX"
  detailLevel: "identifiersOnly"

# Get full schema for a table
mcp__airtable__describe_table
  baseId: "appXXX"
  tableId: "tblXXX"

Progress Indication

For large audits (10+ tables), show progress:

Analyzing fields...
  Base: Projects (1 of 3)
    Table: Tasks (1 of 5)... found 24 fields
    Table: Milestones (2 of 5)... found 12 fields
    ...

Rate Limiting

Airtable API has a 5 requests/second limit. For bases with many tables:

• Add 200ms delay between describe_table calls
• This prevents rate limit errors during large audits

---

Step 3: Analyze Fields for Issues

For each field, check for these issue types:

Issue Type 1: Whitespace

Detection: Field name has leading or trailing whitespace

// Regex pattern
/^\s|\s$/

Examples:

• "Status " (trailing space)
• " Name" (leading spaces)

Fix: Trim the whitespace

Issue Type 2: Near-Duplicates

Detection: Two fields with very similar names that likely represent the same thing

Consider:

• Levenshtein distance <= 2 (typos)
• Semantic similarity: "Email" vs "E-mail" vs "email"
• Same field type increases likelihood of duplicate

Examples:

• "Email" and "E-mail" (hyphen variation)
• "Phone" and "Pbone" (typo)
• "Status" and "Staus" (typo)

Fix: Suggest keeping one, clarifying, or merging

Issue Type 3: Similar/Confusing Names

Detection: Fields with same base name plus numeric suffix or vague modifier

Patterns:

• "Field" and "Field 2" and "Field 3"
• "Date" and "Date (old)" and "Date - new"

Examples:

• "Status" and "Status 2" (likely accidental duplicate)
• "Notes" and "Notes (backup)"

Fix: Suggest renaming with clearer distinction or merging

Issue Type 4: Inconsistent Casing

Detection: Same field name with different casing conventions

Compare case-insensitively, flag if actual casing differs:

• "firstName" vs "FirstName" vs "first_name" vs "First Name"

Fix: Standardize to the dominant casing convention in the base, or Title Case if no clear convention

Emoji Prefix Awareness

The main Airtable skill uses emoji prefixes like 📧, 📅, 🔗.

IMPORTANT: Strip emoji prefixes before comparison to avoid false positives.

// Strip prefix pattern: emoji characters at start of name
const cleanName = fieldName.replace(/^[\p{Emoji_Presentation}\p{Extended_Pictographic}\uFE0F]+\s*/gu, '');

Examples:

• "📧 Email" and "Email" are NOT duplicates (one has emoji prefix)
• "📧 Primary Email" and "📧 Contact Email" - compare "Primary Email" vs "Contact Email"
• "👷🤖 Sales" - strip multiple prefixes: "Sales"

---

Step 4: Present Findings

Issues Found

Present in a clean table:

Found 4 issues in "Projects" base:

| # | Table | Field | Issue | Suggested Fix |
|---|-------|-------|-------|---------------|
| 1 | Tasks | "Status " | Trailing space | Rename to "Status" |
| 2 | Tasks | "email" | Near-duplicate of "Email" in Contacts | Clarify or merge |
| 3 | Projects | "Start Date" | Inconsistent casing with "Start date" | Standardize to "Start Date" |
| 4 | Contacts | "  Name" | Leading spaces | Rename to "Name" |

Cross-Table Observations

If same-named fields appear across tables, present as informational (not actionable):

Cross-table observations (may be intentional):
  - "Email" exists in Tasks, Contacts, and Companies
  - "Status" exists in Tasks, Projects, and Milestones

These are common patterns and often intentional. No action needed unless you want to clarify naming.

Zero Issues Found

No field naming issues found in "Projects" base. All 47 fields look good!

Step 5: Remediation Options

Ask the user how to proceed:

How would you like to proceed?
  1. Apply all fixes automatically
  2. Review and approve each fix
  3. Export report only (I'll fix manually)

---

Step 6: Apply Fixes

Option 1: Auto-Fix All

For each fixable issue (whitespace, casing), apply the fix using the Airtable API.

API Endpoint:

PATCH /v0/meta/bases/{baseId}/tables/{tableId}/fields/{fieldId}
Content-Type: application/json
Authorization: Bearer {PAT}

{
  "name": "New Field Name"
}

Progress output:

Applying fixes...
  ✓ Renamed "Status " → "Status" in Tasks
  ✓ Renamed "Start date" → "Start Date" in Projects
  ✓ Renamed "  Name" → "Name" in Contacts
  ⚠ Skipped "email" - requires manual decision (cross-table duplicate)

Done! 3 fixes applied, 1 skipped.

Option 2: Review Each Fix

Present each issue one at a time:

Issue 1 of 4:
  Table: Tasks
  Field: "Status " (trailing space)
  Type: Single Select
  Suggested: Rename to "Status"

  [1] Apply fix  [2] Skip  [3] Custom name  [4] Skip remaining

If user chooses [3] Custom name:

Enter new name for field: _

After each decision, apply fix (if approved) and move to next.

Option 3: Export Report

Generate a markdown report:

## Field Audit Report

**Base:** Projects
**Generated:** 2026-02-05
**Total fields analyzed:** 47
**Issues found:** 4

### Issues

| Table | Field | Issue Type | Suggested Fix |
|-------|-------|------------|---------------|
| Tasks | "Status " | Whitespace | Rename to "Status" |
| Tasks | "email" | Near-duplicate | Clarify vs "Email" in Contacts |
| Projects | "Start date" | Casing | Rename to "Start Date" |
| Contacts | "  Name" | Whitespace | Rename to "Name" |

### Manual Fix Instructions

1. **Tasks > "Status "**
   - Click field dropdown → Edit field
   - Change name to: `Status`
   - Save

2. **Tasks > "email"**
   - Review relationship with Contacts > "Email"
   - If same purpose: delete one and update records
   - If different purpose: rename to clarify (e.g., "Task Email")

3. **Projects > "Start date"**
   - Click field dropdown → Edit field
   - Change name to: `Start Date`
   - Save

4. **Contacts > "  Name"**
   - Click field dropdown → Edit field
   - Change name to: `Name`
   - Save

Edge Cases

Naming Conflict

If the target name already exists:

⚠ Cannot rename "Status " → "Status" (field already exists)

Options:
  1. Rename to "Status (copy)"
  2. Skip this fix (delete duplicate manually first)
  3. Enter custom name

Permission Error

If rename fails due to permissions:

⚠ Unable to rename "Status" - insufficient permissions.
   You may need Editor access to this base.

Switching to report-only mode for remaining fixes...

MCP Not Available

If MCP tools aren't configured:

Airtable MCP tools not available. To use this skill, configure the Airtable MCP.

Alternatively, you can provide your schema manually by:
1. Opening your base in Airtable
2. Going to Help → API documentation
3. Copying the field list for each table

Best Practices

1. Start with report mode for large bases to review changes before applying
2. Back up critical bases before auto-fixing (though renames are reversible)
3. Communicate with team before bulk renaming fields in shared bases
4. Consider formulas - Airtable updates formulas automatically when fields are renamed, but external integrations may break
5. Run periodically - audit bases every few months to prevent naming debt
