Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/ksegit/version-sentinel/claude-mdgit clone --depth 1 https://github.com/KSEGIT/Version-SentinelWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00678 | $0.00678 |
| Opus 5 | $0.00339 | $0.00339 |
| Sonnet 5 | $0.00136 | $0.00136 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
Version-Sentinel CLAUDE.md scanned grade A with 1 finding 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 yesterday.
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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Version Sentinel
Claude Code plugin that hard-blocks dependency additions, bumps, and downgrades until a fresh, source-cited version check is recorded. Multi-agent: ships adapters for Claude Code (also covers z.ai GLM Coding Plan / ZCode, which reuse the Claude Code plugin format), Kimi Code, GitHub Copilot (VS Code), Gemini CLI, OpenAI Codex, and Zed.

hooks/gemini-hooks.json Gemini CLI hook definitions (SessionStart startup, BeforeTool, AfterTool) — separate because Claude's plugin loader rejects Gemini keys in hooks/hooks.json; Gemini only auto-loads hooks/hooks.json, so point/copy this file on Gemini install (upstream: google-gemini/gemini-cli#25630)

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.

Version-Sentinel CLAUDE.md is an instructions file published in the GitHub repository KSEGIT/Version-Sentinel (3 stars, last pushed 2d ago), licensed MIT. It adds 678 tokens to every session, about $0.0034 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
