Handoff file check

Manual folder handoffs are prone to silent failures like zero-byte files, accidental duplicates, and missing assets. This skill automates the pre-delivery audit by generating a local file inventory and a handoff review based on SHA-256 hashes. It ensures your delivery folder matches your expected manifest before you send it to a client.

What it does

• Inventory generation creates a structured JSON map of all local files including size and SHA-256 hashes.
• Manifest reconciliation compares actual folder contents against a provided list of required and optional deliverables.
• Integrity checking flags zero-byte files that may have failed during export or transfer.
• Duplicate detection groups byte-identical files using hashes to identify redundant exports or assets.
• Review reporting produces a Markdown summary for stakeholders highlighting missing files and required owner decisions.

How it works

1. Define scope by providing a local delivery folder path and an optional list of expected filenames.
2. Execute audit using the internal Python helper to scan the directory and generate the handoff-inventory.json.
3. Analyze results to identify required_unverified paths, empty files, and hash-identical duplicates.
4. Generate report in handoff-review.md format, detailing exact discrepancies and providing a draft handoff note.

Frameworks & tools

This skill requires a Python 3.9+ execution environment. It uses standard filesystem operations and SHA-256 hashing to verify file integrity without external dependencies or internet access.

Why this beats prompting it yourself

Generic prompts often hallucinate file existence or fail to catch byte-level duplicates across deep directory structures. This skill uses a dedicated Python script to ensure 100% accuracy in file sizes and hashes, providing a verifiable audit trail that manual chat inspection cannot replicate.

Use cases

• Freelance handoffs to verify all website assets are present before client billing.
• Agency staging to ensure export folders don't contain zero-byte placeholders.
• Project archiving to identify and remove redundant byte-identical assets.
• Asset reconciliation to map loose file lists to actual directory structures.

Known limitations

Does not perform visual quality checks, malware scanning, or private data detection. Requires local file-reading permissions and Python 3.9+. Does not support cloud storage or wildcards in manifests.
