Verity plugins 0.1.0 — Claude Code and Codex
Verity plugins 0.1.0 provides separate native packages for Claude Code and Codex, each with the hosted MCP connection and three workflows: service-check, compare-marks, and explain-result.
Install
Claude Code:
claude plugin marketplace add erichare/verity@plugins-v0.1.0
claude plugin install verity@verityCodex:
codex plugin marketplace add erichare/verity@plugins-v0.1.0
codex plugin add verity@verityStart a new session and ask: “Use Verity to check service health and list the calibration references. Do not upload any scans.”
Downloads
verity-claude-0.1.0.zip: Claude Code plugin, skills, native manifest, MCP connection, licenses, and standalone marketplace.verity-codex-0.1.0.zip: Codex plugin with the same workflows and its own native manifest and standalone marketplace.SHA256SUMS: checksums for both ZIPs.
For ZIP installation, extract the appropriate archive into its own folder. Pass that folder's absolute path to the client's plugin marketplace add command, then install verity@verity with the command above. No monorepo checkout is required.
Both plugins connect to https://api.verity.codes/mcp. Comparison calls upload supplied scan contents to that service. Single-land bullet results are diagnostic only. Preserve named references, uncertainty, scope warnings, and refusals. Verity reports weight of evidence, not an identity or match verdict.

Source and verification
This release is pinned to commit 12de569b64eae33b7ab0a2eccf18ca5c0eba162c. Package tests, native Claude/Codex loading, Python/R/Rust suites, and the web build passed locally. All nine CI jobs and the CodeQL checks passed on that commit. The uploaded assets were downloaded and checksum-verified, and match the CI-built packages byte for byte. Claude installed the pinned public marketplace successfully in an isolated configuration. Codex's native loader recognized the fetched release, all three skills, and the MCP connection.
The accompanying project sweep is tracked in PR #169, pending the repository's required review. This plugin release does not deploy backend changes or publish a new codec version to PyPI or crates.io. It is a repository marketplace distribution, not an official Anthropic or OpenAI directory listing.
The source includes corrected X3P validity-mask decoding, which can change results for affected scans. Historical scientific figures have not been recomputed because the full source datasets were unavailable locally. See the decoder impact note.
