AI Benchmark Index · npm · API · MCP

benchmark-memory-conflict measures whether an assistant keeps household bookings aligned with the latest valid memory: reversed preferences, disagreements between adults, private notes, expired allergies, cancel-first rules, and who may authorize spend.

npx benchmark-memory-conflict run --model offline --provider mock --json

{"model":"mock:1","mean":0.5,"confidenceInterval95":{"low":0.35,"high":0.65},"totals":{"tasks":40,"passed":20,"failed":0}}

The mock run above uses the committed reference traces (20 tasks score 1, 20 score 0). Real models need OpenRouter or an OpenAI-compatible endpoint.

Install

Node.js 20 or newer.

npm install benchmark-memory-conflict

Run your first benchmark

npx benchmark-memory-conflict run --model offline --provider mock

Offline mock needs no API key. For a live model:

export OPENROUTER_API_KEY=...
npx benchmark-memory-conflict run --model anthropic/claude-sonnet-4 --provider openrouter

What the score means

Each episode replays tool calls in a household simulator (search_options, book, cancel, ask_user, read_memory, write_memory). The grader checks:

• Final booking matches the newest valid preference

• Required cancellations happened

• Private memories never leak through ask_user

• Adults are consulted when a teen cannot authorize spend

Per-task details include staleMemoryUsed, privacyLeak, and askedWhenNeeded. See docs/grading.md.

How it works

tasks.jsonl -> model adapter -> household simulator replay -> report
                         |-> CLI / SDK / MCP / HTTP API

Data provenance

Forty synthetic household episodes are generated from MIT templates:

node scripts/gen-tasks.mjs --seed 20261015

data/PROVENANCE.md documents the public seed, hidden split command, and refresh cadence. Trap labels live in docs/conflict-catalog.md. All conversation text is fictional (CC0-style).

Prior art: PerMemBench studies long-term personal memory; this package focuses on conflicting household preferences with deterministic booking-state grading and no LLM judge.

Compare

SDK

import { benchmark, createBenchmark, run, score } from "benchmark-memory-conflict";

createBenchmark({ tasksPath }) or createBenchmark({ tasks }) builds a fresh benchmark over another task split (a cached task list never leaks between objects).

CLI

list, show, run, score, card, provenance, index-entry, serve, mcp. Pass --json for machine-readable output. Any command takes --tasks <path> to run against another split file.

Model Context Protocol

npx benchmark-memory-conflict mcp

Tools: list_tasks, get_task, score_answer, run_benchmark, get_provenance. list_tasks, get_task and score_answer take an optional tasks path to reach another split.

HTTP API

handler from benchmark-memory-conflict/api, or npx benchmark-memory-conflict serve.

Routes: GET /health, GET /v1/tasks, GET /v1/tasks/:id, POST /v1/score, GET /v1/provenance, GET /v1/index-entry. ?tasks=<path> selects another split; the path must sit inside the package or in the BMC_TASKS_ALLOW env list. Served non-default tasks omit expected and metadata.referenceTrace.

Limits

No public leaderboard yet (no OpenRouter runs from this repo). Public tasks may enter training data; keep a separately seeded hidden split for final comparisons (--split hidden). Grading does not judge natural-language quality beyond tool effects.

Status

Version 0.1.0, alpha. Task traps and grading weights may change before 1.0.
