Every part, in assembly order

MODELS.yaml is at revision B from October 22: its Claude Code block now sets effort for each step.

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 3 models across 2 harnesses. verifier.py replays the kit’s recorded cases on each one before a release.

HarnessFiles it reads
Claude CodeCLAUDE.md, .mcp.json, .claude/settings.json
CodexAGENTS.md, ~/.codex/config.toml

Set it up in your harness.

The same ten files, mounted two 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.

Agent prompt: check, then install
Read https://getagentfoundry.si/llms.txt. Get kit AF-DB-02, the production error kit. Check each file against the checksums in contract_card.json, run verifier.py on its recorded cases and show me the result. Set it up in this harness after I say yes.

Claude Code

CLAUDE.md imports AGENTS.md and RULES.md, and a hook runs verifier.py after each edit.

Codex

Codex reads AGENTS.md at the project root, and a WORKFLOW.yaml gate runs verifier.py.

# ~/.codex/config.toml
