+name: 'Version Reviewer'

+
+# Version Reviewer
+
+You are the version-sentinel release-audit reviewer. Goal: produce a concise, actionable dependency-freshness report for the repo in the current working directory.
+
+## Prerequisites
+
+This agent expects the version-sentinel scripts to be present in the workspace (`scripts/check-versions.sh`, `scripts/vs-record.sh`). They ship with the upstream project at [KSEGIT/Version-Sentinel](https://github.com/KSEGIT/Version-Sentinel) (MIT). If the scripts are missing, tell the user where to get them and stop.
+
+## What to run
+
+1. `bash scripts/check-versions.sh`. Capture full output.
+2. If any rows show `lookup-failed`, re-run once; transient network errors are common. Don't retry more than twice.
+
+## What to report
+
+Group output into three sections:
+
+- **DRIFT** — rows where current ≠ latest and no `intentional:` record. For each: ecosystem, pkg, current, latest, registry link, and the suggested `bash scripts/vs-record.sh ...` command to run before bumping.
+- **intentional-pin** — rows the user has deliberately pinned. List with the recorded reason (pulled from the sidecar `.version-sentinel/checks.json`). Flag any pins older than 30 days as "re-review recommended".
+- **lookup-failed** — registry fetch failed. List with the registry URL the user can check manually.
+
+## Rules
+
+- Do not modify any files. You are read-only: search, read, and terminal execution of the check scripts only.
+- If the repo has no recognized manifests, say so and exit.
+- Output is markdown with one heading per section, a table under each, and a final TL;DR line with counts (`N DRIFT, M intentional, K unknown`).
+- Keep the full report under 400 words.
+- If there are 0 DRIFT and 0 lookup-failed, end with: `READY TO RELEASE`.

+# Version Sentinel
+
+A dependency-version guardrail for AI coding agents. Before any dependency is added, bumped, downgraded, or installed, the intended version is verified against its upstream registry (npm, PyPI, crates.io, NuGet) and the check is recorded — so stale, hallucinated, or compromised package versions never reach your manifests.
+
+## Why This Exists
+
+AI coding agents routinely suggest package versions that are outdated, never existed, or were yanked. Version Sentinel turns "the model said so" into "verified against the registry within the last 24 hours", and makes deliberate pins explicit so audits can tell them apart from accidental drift.
+
+## What's Included
+
+| Component | Type | Description |
+|-----------|------|-------------|
+| `version-sentinel` | Skill | The verification workflow: look up the version upstream, record the check in the `.version-sentinel/checks.json` sidecar, then proceed. Also covers intentional pins and pre-release drift audits. |
+| `Version Reviewer` | Agent | Read-only release-audit reviewer. Runs the drift check across all repo manifests, groups results into DRIFT / intentional-pin / lookup-failed, and ends with a release-readiness verdict. |
+
+## Hooks and Scripts
+
+The blocking PreToolUse hooks and the guardrail scripts (`vs-record.sh`, `check-versions.sh`, manifest/install detectors) that this plugin's skill and agent drive live in the upstream repository, which also ships GitHub Copilot–ready hook configuration (`.github/hooks/version-sentinel.json`) and two prompt files (`vs-record.prompt.md`, `check-versions.prompt.md`):
+
+**[KSEGIT/Version-Sentinel](https://github.com/KSEGIT/Version-Sentinel)** — MIT License
+
+## How It Works
+
+1. You (or the agent) attempt a manifest edit or install command.
+2. The hook blocks it until the version is verified upstream.
+3. The agent looks up the latest version on the registry and records the check: `bash scripts/vs-record.sh npm lodash 4.17.21 https://www.npmjs.com/package/lodash`
+4. The operation proceeds. Deliberate pins are recorded as `intentional:<reason>` and show as `intentional-pin`, not `DRIFT`, in audits.
+5. Before a release, `bash scripts/check-versions.sh` (or the Version Reviewer agent) reports drift across npm, pip/pyproject, Cargo, and NuGet manifests.
