Is the Knowledge Cutoff Awareness skill free?

Yes. The skill itself is free from imkohenauser/antigravity-starter-ja. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Knowledge Cutoff Awareness SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Knowledge Cutoff Awareness?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Knowledge Cutoff Awareness with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 4c9b086

Actually ran the bundled node scripts/get_date.js live: correctly returned the real system date (verified against session context) and computed +3 weeks accurately, versus a baseline model answer that has no ground truth for 'today' and would have to guess or hedge.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Knowledge Cutoff Awareness does

Runs a bundled node scripts/get_date.js wrapper around the system clock to return the true current date/time in ISO 8601 or human-readable form, with simple relative-offset arithmetic (+1d, -2w, yesterday). Triggers on any question involving today's date, elapsed/remaining time, or recent events that could otherwise be answered from a stale training cutoff.

Commands — how to trigger Knowledge Cutoff Awareness

/knowledge-cutoff-awareness Grounds the agent in the real current date via a small Node script instead of guessing from training data.

It also activates on plain-language prompts like these:

What's today's actual date, not your training cutoff guess?
Tell me exactly what date it'll be three weeks from now
Is three weeks from today going to land after August 1st?
