Standard files and size budgets: the AgentFoundry blog, October 18, 2026. Part numbers, tests and revisions are sample previews.
What it works with.
Checked with 4 models across 3 harnesses. verifier.py replays the kit’s recorded cases on each one before a release.
| Harness | Files it reads |
|---|---|
| Claude Code | CLAUDE.md, .mcp.json, .claude/settings.json |
| Codex | AGENTS.md, ~/.codex/config.toml |
| OpenCode | AGENTS.md, opencode.json |
Set it up in your harness.
The same ten files, mounted three ways. Your models, permissions and project stay yours. Or hand the job to your agent with this prompt.
Installed kit files carry the MIT licence: use, change and share them in your own projects. Builder installs kits over MCP, with setup for each harness and every new revision.
