What is it for?
Preparing, validating, publishing, tagging, and announcing an explicitly requested Bex Security release.
Why use it?
They enforce matching versions, a clean main branch, safe Git history, and protected handling of registry credentials.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions AGENTS.md; mentions Codex.

This is bex-co/bex-security's own configuration. It tells Claude Code how to work on bex-security itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything bex-security configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Release Bex Security

Publish one immutable @bex-co/bex-security version from main. A successful release has the same version in sdk/typescript/package.json, npm, the bex-v<version> Git tag, and the GitHub release.

Preconditions

  1. Read the repository AGENTS.md instructions and review all material that will become public.

  2. Require a clean worktree on main. Never stash, discard, amend, rebase a published commit, or force-push.

  3. Fetch origin and the canonical openai/codex-security upstream. Bring local main to origin/main with a fast-forward only.

  4. Confirm sdk/typescript/package.json names @bex-co/bex-security, points to the Bex repository, and retains codex-security only as a compatibility bin.

  5. Authenticate to the public npm registry. When .env provides NPM_TOKEN, load it without printing it and pass it only through the process environment:

    env "npm_config_//registry.npmjs.org/:_authToken=$NPM_TOKEN" npm whoami --registry=https://registry.npmjs.org
    

    Do not create or commit an npm credentials file.

Choose The Version

Resolve the merged upstream baseline with git merge-base main upstream/main. Read the upstream package version from that commit rather than claiming an unmerged upstream release.

  • Versions are <upstream-version>-bex.<release-number>.
  • Use .1 for the first Bex release on a new upstream version.
  • Otherwise increment the greatest published Bex release number for that exact upstream version.
  • Never reuse, overwrite, deprecate, or unpublish a version.
  • If npm already contains the intended version, enter recovery mode: do not bump or publish it again; verify the archive and complete only missing Git or GitHub release metadata.

Update these fields together:

  • version
  • bex.upstreamVersion
  • bex.upstreamCommit
  • .github/bex-release-notes.md release marker, heading, summary, highlights, and upstream base

Release notes must describe user-visible Bex behavior generically. Do not copy private scan targets, findings, credentials, customer context, local paths, or unreviewed commit messages into public metadata.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
