AEB builds small, independently usable tools that make automated decisions and failures easier to inspect, reverse, reproduce, and prove. Start with ResiliReplay when an MCP server works on the happy path but its recovery behavior is unknown.
Route. Transact. Verify. Replay. Probe. Prove.
| Need | Start here | Status | Concrete output |
|---|---|---|---|
| Preserve constraints while selecting an agent, model, or MCP route | GaugeMesh | 0.2.0 GitHub developer preview; crates.io unavailable | selected or denied decision and digest-bound conservation evidence |
| Isolate, inspect, accept, or roll back coding-agent edits | AgentTX | 0.2.0 GitHub alpha; npm remains 0.1.0 | transaction ledger, diff, risk report, and rollback receipt |
| Retry a frozen model only while an explicit verifier justifies it | Verifaxis | 0.2.0 GitHub research prerelease; PyPI unavailable | claim, verifier decisions, stopping reason, and offline-verifiable evidence |
| Inject and replay deterministic MCP failures | ResiliReplay | 0.7.0 released flagship | recovery evidence and an executable regression |
| Find a reproducible qualitative simulation transition | PhaseProbe | 0.3.0 released on PyPI | bracketed transition evidence, standalone verification, and generated pytest regression |
| Check a released Action from outside its source repository | ResiliReplay Action Smoke | evidence infrastructure | downstream workflow result and validated artifacts |
The tools exchange versioned files or invoke released CLIs at process boundaries; none requires the rest of the portfolio. The smoke repository is intentionally not a user-facing product.

With Node.js 22 or 24:
npx --yes resilireplay@0.7.0 mcp demo --keepThe credential-free local demo runs a clean MCP call, reproduces one deterministic failure, verifies
bounded recovery with no duplicate effect, generates and executes a regression, and keeps the
evidence under .resilireplay/demo/. See the
five-minute MCP guide
and the
independent Action smoke.
- Agent reliability: GaugeMesh routes while preserving declared constraints; AgentTX contains repository edits; Verifaxis evaluates explicit claims; ResiliReplay tests MCP recovery. Use only the stages the task actually needs.
- Scientific reliability: PhaseProbe brackets a qualitative transition and exports a pytest regression. Verifaxis or ResiliReplay belongs here only when a real verifier or failure-replay boundary is present.
- These tools provide evidence for their documented scopes; they are not security certifications.
- AgentTX does not sandbox a child process or reverse external side effects.
- GaugeMesh is a GitHub/GHCR developer preview and is not on crates.io. Verifaxis remains a research prototype distributed as a GitHub prerelease wheel, not through PyPI.
- AgentTX 0.2.0 is available from GitHub; the npm registry still serves 0.1.0 as latest.
- PhaseProbe requires the user to define a scientifically meaningful observable and predicate.
- ResiliReplay requires explicit ownership and approval before exercising remote or effectful tools.
