Harnesses

The container includes /home/user/src/AGENTS.md with information about preinstalled tools.

Supported agents

Agent	Config file
amp	~/.config/amp/AGENTS.md
claude	~/.claude/CLAUDE.md
codex	~/.codex/AGENTS.md
gemini	~/.gemini/GEMINI.md
kilo	~/.kilocode/rules/*.md
opencode	~/.config/opencode/AGENTS.md
pi	~/.pi/agent/AGENTS.md
qwen	~/.qwen/QWEN.md
goose	~/.config/goose/AGENTS.md
kimi	~/.kimi/KIMI.md

Sharing the same AGENTS.md across harnesses

By default, each harness looks for its own config file (e.g. ~/.claude/CLAUDE.md, ~/.pi/agent/AGENTS.md). If you'd prefer a single AGENTS.md shared across all your agents, symlinks make this easy:

mkdir -p ~/.config/agents ~/.config/amp ~/.claude ~/.codex ~/.config/goose ~/.gemini \
         ~/.kimi ~/.kilocode/rules ~/.config/opencode ~/.pi/agent ~/.qwen

echo "Read ~/AGENTS.md if present." >> ~/.config/agents/AGENTS.md
ln -s ../../.config/agents/AGENTS.md ~/.config/amp/AGENTS.md
ln -s ../.config/agents/AGENTS.md    ~/.claude/CLAUDE.md
ln -s ../.config/agents/AGENTS.md    ~/.codex/AGENTS.md
ln -s ../.config/agents/AGENTS.md    ~/.config/goose/AGENTS.md
ln -s ../.config/agents/AGENTS.md    ~/.gemini/AGENTS.md
ln -s ../.config/agents/AGENTS.md    ~/.kimi/KIMI.md
ln -s ../../.config/agents/AGENTS.md ~/.kilocode/rules/AGENTS.md
ln -s ../../.config/agents/AGENTS.md ~/.config/opencode/AGENTS.md
ln -s ../../.config/agents/AGENTS.md ~/.pi/agent/AGENTS.md
ln -s ../.config/agents/AGENTS.md    ~/.qwen/AGENTS.md

You can skip any harness you don't use. Each agent works fine with its own config file too: nothing requires symlinks.

Sharing skills across harnesses

If you use multiple agents, you can share the same skills directory rather than copying skills into each harness's location:

mkdir -p ~/.config/agents/skills ~/.claude ~/.codex ~/.config/goose \
         ~/.gemini/antigravity ~/.kimi ~/.kilocode ~/.config/opencode ~/.pi/agent ~/.qwen

ln -s ../.config/agents/skills/          ~/.claude/skills
ln -s ../.config/agents/skills/          ~/.codex/skills
ln -s ../.config/agents/skills/          ~/.config/goose/skills
ln -s ../../.config/agents/skills/       ~/.gemini/antigravity/skills
ln -s ../.config/agents/skills/          ~/.gemini/skills
ln -s ../.config/agents/skills/          ~/.kimi/skills
ln -s ../.config/agents/skills/          ~/.kilocode/skills

Again, none of this is required. Each harness looks in its own directory by default.

Skills locations by harness:

Agent	Skills path
amp	~/.config/agents/skills/**/SKILL.md
claude	~/.claude/skills/<name>/SKILL.md
codex	~/.codex/skills/**/SKILL.md
gemini	~/.gemini/skills/<name>/SKILL.md
kilo	~/.kilocode/skills/<name>/SKILL.md
opencode	~/.config/opencode/skill/<name>/SKILL.md
pi	~/.pi/agent/skills/**/SKILL.md
qwen	~/.qwen/skills/<name>/SKILL.md
goose	~/.config/goose/skills/**/SKILL.md
kimi	~/.kimi/skills/<name>/SKILL.md
