Agent Portability Checker 🔌

Audit an agent skill for platform lock-in. Auto-fixes what it can, flags what needs manual attention.

Why

Skills with hardcoded paths only work on one platform. This tool catches those issues and fixes them — making your skills work everywhere agents run.

When to Use

• "Is this skill portable?"
• "Make this skill cross-platform"
• "Check for hardcoded paths"
• "Prepare a skill for other agents"

How to Run

python3 scripts/audit.py <skill_dir>          # audit only
python3 scripts/audit.py <skill_dir> --fix    # auto-fix + audit
python3 scripts/audit.py <skill_dir> --json   # structured output

What It Checks

📍 Hardcoded paths     — platform-specific dirs like ~/.<platform>/ in scripts
🔧 SKILL_DATA_DIR      — env var support for data dir resolution
📦 XDG fallback        — ~/.config/<skill>/ fallback path
🔌 Platform CLI deps    — external binary dependencies (e.g. clawhub, gh)
🏷️  User-Agent strings — platform names in HTTP headers
📄 SKILL.md paths      — platform-specific path references in docs
🖥️  Headless setup     — OAuth scripts without --no-browser flag
🔑 Credential env vars — file-only credentials with no env var alternative

Output Example

❌ github-growth-tracker — 8 errors, 9 warnings (9 auto-fixable)

📍 Hardcoded Paths
  ❌ scripts/github_tracker.py:28: ~/.<platform>/ [auto-fix]
  ❌ scripts/github_tracker.py:31: ~/.<platform>/ [auto-fix]

🔧 SKILL_DATA_DIR: Not supported — scripts use hardcoded paths
🔧 XDG Fallback: Missing ~/.config/ fallback path

Two-Phase Flow

1. Audit — show all findings (auto-fixable + manual)
2. Fix — apply auto-fixes, show brief "what changed" confirmation

The agent reads the script output and formats it for the current channel. See

references/formatting.md

for Slack/WhatsApp/Discord styling.

Auto-Fixes

• Replaces

  ~/.<platform>/credentials/

  with

  $SKILL_DATA_DIR

• Replaces

  ~/.<platform>/workspace/data/<skill>/

  with

  $SKILL_DATA_DIR/<skill>/

• Strips platform names from User-Agent strings
• Replaces hardcoded paths in SKILL.md with

  <DATA_DIR>

  placeholder

⚠ Output styling is never modified. Emojis, formatting, and visual elements in script output are preserved exactly as-is.

Manual flags require human review (platform CLI deps, headless setup, env var alternatives).

Formatting

Read

references/formatting.md

for channel-specific styling (Slack, WhatsApp, Discord, terminal).

The Portability Pattern

Skills that work everywhere follow this:

1. Resolve data dir via $SKILL_DATA_DIR (set by agent platform)
2. Fall back to ~/.config/<skill>/ (XDG-compliant, works everywhere)
3. Accept credentials via env var OR file (env var preferred)
4. Output to stdout — no platform messaging APIs
5. Self-contained scripts — no platform SDK imports
