AI Agent Reliability Sprint

Ai Agent Tool Call Id Validation

Stop MiniMax M2.1 API HTTP 400 rejections caused by tool_result tool_id mismatches

Your AI agent dispatches tool calls, but the MiniMax API rejects the responses with:
invalid_request_error: invalid params, tool result's tool id(...) not found (2013)
The server cannot validate the tool_id your agent references. This is a session state mismatch — not a connectivity issue.

What you get

1

Tool ID Lifecycle Audit Report

PDF, 12-18 pages. Documents the exact point where your agent's tool_id generation diverges from MiniMax's expectations. Includes annotated session traces and failure tree analysis.

2

Deterministic Replay Fixture

Python test case that deterministically reproduces the HTTP 400 rejection. Can be run locally to validate fixes without hitting the live API.

3

State Map Implementation YAML

Configuration template showing how to cache and persist tool_id values across conversation turns. Prevents ID regeneration that causes the 2013 error.

4

Pre-Flight Validation Schema

YAML contract check that validates tool_result payloads before submission. Catches malformed tool_id references before they hit the MiniMax API.

5

Reference Patch Diff

Annotated diff file showing the exact code changes needed in openclaw (or equivalent agent) to fix tool_id persistence. Includes rollback instructions.

How it works

Day 1 Session trace ingestion + failure mode mapping
Day 2 Replay fixture development + root cause isolation
Day 3 State map schema design + pre-flight validator build
Day 4 Reference patch implementation + internal QA
Day 5 Artefact delivery + 30-minute walkthrough call

Frequently Asked

What if my agent isn't openclaw?

The replay fixture and state map implementation are agent-framework-agnostic. The principles apply to any AI agent that manages tool call IDs across conversation turns. The reference patch targets openclaw specifically, but the diff methodology transfers to other frameworks.

What data do you need from me to start?

At minimum: (1) a sample HTTP 400 response payload showing the tool_id error, and (2) your agent's tool call dispatch code or a snippet of the session where the mismatch occurs. If you have full request/response logs, that's better but not required.

Does this fix the underlying MiniMax API issue?

No — this sprint fixes your agent's handling of tool_id lifecycle. If MiniMax has changed validation rules in 2026, the pre-flight validator and state map will adapt to those rules. The artefacts are designed to be updated if the API specification changes.

Is there a guarantee the fix will work?

The deliverables are production-grade artefacts based on the confirmed GitHub issue (#76) in the MiniMax-M2 repository. The replay fixture ensures you can validate the fix independently before deploying. Walkthrough on Day 5 covers implementation guidance.
