 ### Script CLI changes
 
+- Added Phase 23 `skills/agent-security/scripts/preflight.py` to run config-risk, exposure scoring, and prompt-injection signal checks together for local and CI smoke jobs, with JSON default, Markdown summaries, `--format sarif`, `--strict`, and fail-closed missing inputs.
 - Added `--format sarif` to `skills/agent-security/scripts/flag_prompt_injection_signals.py` and `skills/agent-security/scripts/score_prompt_injection_exposure.py` for GitHub Code Scanning while keeping JSON as the default.
 - Added additive JSON/SARIF finding `fingerprint` values plus `--compare-reports` and `--fail-on-new` to `skills/agent-security/scripts/config_risk_summary.py` for stored-report regression gates.
 - Replaced ad-hoc ZIP packaging with reproducible `scripts/package_skills.py`, deterministic `dist/MANIFEST.json` release metadata, and a non-mutating `--check` drift gate while preserving `./package-skills.sh`.

 ## Phase 23: Combined local preflight CLI
 
-**Status:** Planned
+**Status:** Shipped
 **Goal:** Provide a single dependency-light preflight command that runs config-risk, exposure scoring, and prompt-injection signal checks together for local and CI smoke jobs.
 
+### Completed
+
+1. Added `skills/agent-security/scripts/preflight.py` wrapping the three existing scanner CLIs via subprocess with JSON default output.
+2. Added `--format markdown|sarif` combined summaries and `--strict` fail-on-high-risk gates without changing child scanner defaults.
+3. Missing `--config` / `--text` inputs fail closed with empty stdout.
+4. Documented local/CI smoke usage in README, `docs/ci-integration.md`, and `skills/agent-security/SKILL.md`.
+
 ## Implementation order
 
 1. Finish or merge PRs that already cover roadmap work before starting duplicate branches.
