Tool Contract MigrationOperated by Reality Contact, LLC

Agent tool contracts

Migrate the tools your agents still call by their old names.

Request a free five-scenario drift map. Reality Contact, LLC traces the old and target contracts through prompts, programs, validators, runtime dispatch, and one working compatibility proof.

The example shows the migration record shape. A real proof uses the buyer's frozen old and target contracts.

A tool contract exists in more places than the runtime.

Prompts, generated programs, registries, typed clients, fixtures, cached schemas, and deployed workers can each carry a different version. Updating the dispatcher leaves old names and arguments active wherever those copies remain.

The visible failure may be tool-not-found, but invalid arguments, changed permissions, altered defaults, and incoherent retry behavior can come from the same migration. A patched prompt can hide one trace while leaving the contract disagreement intact.

The free map reconstructs five complete scenarios.

Each scenario shows the contract a caller saw, the call it produced, validation and dispatch results, semantic differences, recovery, and the exact acceptance condition for the target version.

One high-volume tool receives a working proof so the buyer can inspect the migration path. Private traces, prompts, schemas, and repositories move only after secure intake and written deletion terms.

What comes back from the record

A finished map of the old and target contracts across five representative scenarios, with the failing layer, semantic differences, migration decision, acceptance conditions, and one working compatibility proof for the highest-volume tool.

Turnaround: The free map arrives within three business days after complete contract snapshots, traces, and a safe test path are received.

The migration ends with canary and rollback evidence.

  1. Freeze

    The old and target contracts become versioned snapshots with names, schemas, semantics, permissions, errors, and owners.

  2. Migrate

    Prompts, programs, registries, clients, validators, and fixtures update from one explicit mapping.

  3. Prove

    Deterministic scenarios cover valid calls, failures, authorization, recovery, side effects, and completed tasks.

  4. Canary

    The buyer authorizes bounded traffic and retires the old path only after stop and rollback gates pass.

Why the check is free

The map is free because Reality Contact, LLC is measuring which tool-contract failures support a bounded migration and whether engineering teams want the complete canary and rollback implementation.

Operated by Reality Contact, LLC. Prices are in United States dollars, and refund conditions appear beside the paid implementation. This is software migration and technical testing, and it does not replace legal, security, privacy, compliance, or professional advice. The buyer owns tool semantics, credentials, permissions, caller communication, canary authorization, production release, and contract retirement.

Questions before you send anything

What do I send?

Do not send private schemas, prompts, traces, repositories, credentials, or links through the public form. A person will provide a secure intake method and written deletion terms before you share sensitive material.

What comes back for free?

A finished map of the old and target contracts across five representative scenarios, with the failing layer, semantic differences, migration decision, acceptance conditions, and one working compatibility proof for the highest-volume tool. The free map arrives within three business days after complete contract snapshots, traces, and a safe test path are received.

Where does the service stop?

Reality Contact, LLC implements and tests the migration, but does not invent target semantics, weaken authorization, approve external side effects, select production traffic, or retire a contract without buyer approval. The buyer approves the target semantics and caller set, runs the accepted canary scenarios, and retires the old contract only after compatibility and rollback gates pass. This is software migration and technical testing, and it does not replace legal, security, privacy, compliance, or professional advice.

Do all old calls receive an adapter?

No. An adapter is used only when the buyer confirms semantic equivalence; changed permissions or meaning require an explicit caller migration or a clear failure.

Can the suite prove every model response?

No. It proves stable contract events and the agreed scenarios, while model-dependent variation remains visible for bounded comparison and human review.
