Is the Agile V Behavioral skill free?

Yes. The skill itself is free from Agile-V/agile_v_skills. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Agile V Behavioral SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 4/5.

How do I install Agile V Behavioral?

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 Agile V Behavioral 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: 8.8/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 7c0cb42

Ran a real REQ side by side: without the skill I shipped a 4-class exception hierarchy and a configurable regex nobody asked for; with it, one traceable function plus explicit TC-0031 test cases — the exact anti-pattern its own docs warn against, eliminated in practice.

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

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 8/10

What Agile V Behavioral does

A behavioral guideline document for coding agents working under the Agile V traceability framework (REQ/ART/CR ids). It prevents four common LLM failure modes: silent assumptions, speculative over-engineering, scope creep on edits, and weak/unverifiable success criteria, and triggers when a user references Agile V, REQ/ART/CR ids, or asks to implement a requirement under that process.

How to install Agile V Behavioral

git clone https://github.com/Agile-V/agile_v_skills
cd agile_v_skills
mkdir -p ~/.claude/skills
cp -r agile-v-behavioral ~/.claude/skills/agile-v-behavioral

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Agile V Behavioral

/agile-v-behavioral Anti-pattern guardrails (no silent assumptions, no scope creep) for Agile V coding agents

It also activates on plain-language prompts like these:

Implement REQ-0031 without adding scope nobody asked for
Trace this change request to explicit test cases, no assumptions
Follow the Agile V process while implementing this requirement
