Portable agent skills packaged once and exposed through multiple installation surfaces.

test-challenger is the normalized packaged name for the original test-challenge source skill.

.agents/skills/              # Canonical portable skills
.claude/agents/              # Generated Claude Code subagents
commands/skills/             # Generated Gemini CLI commands
scripts/install_skills.py    # Cross-runtime local installer
scripts/sync_adapters.py     # Regenerates Claude/Gemini adapters

python3 scripts/install_skills.py --target codex all

python3 scripts/install_skills.py --target claude-skills all

python3 scripts/install_skills.py --target claude-subagents all

gemini extensions install https://github.com/MV011/agent-skills

This installs the extension-backed commands:

• /skills:test-challenger
• /skills:comprehensive-pr-review

python3 scripts/install_skills.py --target universal all

That copies the canonical skills into ~/.agents/skills/, which is the shared install surface used by the open Agent Skills convention and similar toolchains.

After changing any SKILL.md, regenerate the Claude and Gemini wrappers:

python3 scripts/sync_adapters.py
