Security plugins

Claude Code and Codex plugins their authors filed under "security". All categories.

Out-of-band Claude Code Stop / SubagentStop hook judges that block 30 LLM dark patterns at the closeout boundary: false-success without evidence, sycophancy, paternalism, permission-loops, vibe time estimates, fake recall, fake stats, fake citations, count-vs-enumeration self-consistency drift, context loss after compaction, multi-agent rollup failures, power-user polish failures, and unreachable new symbols (advisory). Deterministic verdicts, no network calls, no model in the verdict path, Apache-2.0, paper-grade claim ledger.

hawkscan-ci

claudecodex

Configure HawkScan in your CI/CD pipeline. Provider-agnostic: detects GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure Pipelines, Bitbucket, Buildkite, and other CI systems from repo files, edits the pipeline file in place, and prompts for HAWK_API_KEY storage (CI-native secrets store or external secrets manager).

Lets Claude run commands that ask for a password (sudo, ssh, git): a pane inside Claude Code asks you, and the password never reaches the model

GoneTone/cc-askpass 16

Claude-native, governed offensive-OSINT and external attack-surface platform for authorized security teams: multi-agent recon across web/API, identity, cloud, secrets, and people/breach intelligence, with deterministic scope, evidence, and approval controls, a governed agent-to-agent orchestrator, and human-reviewed findings for hand-off to validation and pen-testing. It is not an exploitation framework and does not perform intrusive testing.
