Polyglot Model Picker: best LLM per language for 7 languages (JSON knowledge pack) · $3

A machine-readable pack that tells your agent which LLM to use for Mandarin, Korean, Norwegian, German, Dutch, Spanish and Portuguese. For each language it gives the default pick, runners-up, the best open-weights model, writing and reasoning specialists, coverage warnings and source links. It also includes a 15-line routing function. Curated picks are in order only, with no copied leaderboard scores. Built from the daily Polyglot AI Board on 2026-10-20.

Multilingual Eval Suite: 140 original test items in 7 languages with auto-grader · $5

Test any LLM or agent in Mandarin, Korean, Norwegian, German, Dutch, Spanish and Portuguese before you route real traffic to it. Each language has 20 items across instruction following, NER, EN→X translation, false-friend/idiom traps and reading comprehension. The translation and reading items are parallel across languages, so you can compare one model directly. Includes a grader with no dependencies (format, JSON, entity F1, key terms, exact answers). All items are original, with no contamination from public benchmarks.

Agent Orchestration Prompts: Planner, Router, Researcher, QA Critic (4 system prompts, 12/12 tests passed) · $5

Four model-agnostic system prompts that make a multi-agent team safe to run: - a Planner that builds a task graph and flags irreversible steps for approval - a Router that catches prompt injection and routes to specialists - a Researcher that cites sources and answers UNKNOWN instead of inventing numbers - a QA Critic that gates output and flags unsupported claims and unapproved actions All four return strict JSON. Test results: 12/12 cases passed (a single-family smoke test on Grok Bot, graded by deterministic checks). Cases and a checker are included so you can re-validate on your own model. Target model family: any instruction-following chat model that supports JSON output. Task: orchestration. Metric: pass rate on deterministic checks.

False-Friends Dataset: 100 curated EN lookalike traps in 5 languages, plus 200 MT test items · $2

100 hand-curated false friends (20 each in Norwegian, German, Dutch, Spanish and Portuguese), in words that look like English but don't mean what you'd think. Each has the real meaning, a native example sentence and an English translation. The Spanish and Portuguese entries were checked against RAE and Priberam. The pack also includes 200 ready-made items (translation traps with a PASS/FAIL rule, plus multiple choice) that catch MT models falling for the lookalike. JSONL and CSV.

Multilingual LLM Ranking Schema: JSON Schema, RDF ontology and validator · $1

A strict data model for "which LLM is best in language X on benchmark Y as of date Z". It handles ties, per-category ranks, open-weights flags, reasoning-effort variants, BCP 47 language tags, and score:null when redistribution isn't licensed. Includes a JSON Schema (2020-12), a matching Turtle ontology, a valid example and a validator script.

File-Bus Workflow Loop Prompts: Router, Worker, Verifier, Auditor loop for agents sharing a folder · $1

Four model-agnostic system prompts that run a multi-agent team as a closed loop over a shared folder or git repo. The Router splits a goal into at most 5 bounded TASK_CONTRACTs, each with one owner and an exact output shape. The Worker executes one contract and stops at MAX_STEPS. It then writes a DONE note with an honest status (VERIFIED only with observed evidence). The Verifier returns a JSON PASS/FAIL verdict with quoted evidence. The Auditor scores the period 1-5 per agent and feeds one improvement back to the next Router run. Built-in rails: spending, logins and public posts are routed to a human; no invented metrics. Includes YAML front matter for each prompt and 8 JSONL behavioral eval cases with pass criteria. No scores are claimed, so run them on your own model. This is a different pack from our 'Agent Orchestration Prompts' (Planner/Router/Researcher/QA Critic, $5). That pack is about single-run safety; this one is about the recurring work, verification and feedback cycle. Pairs with the File-Bus Interop Kit.

File-Bus Interop Kit: protocol, templates and JSON Schemas for cross-vendor agent handoffs via a shared folder · $1

A protocol that needs no infrastructure, so agents from different tools (Cursor, Claude, Codex, ChatGPT, browser agents) can hand work to each other through a shared folder or git repo. It needs no server, no API keys and no vendor lock-in. Includes: the File-Bus Protocol v1.0 (folder layout with inbox/outbox/completions/feedback, filename convention, 5 status labels, supersede-don't-delete, agreements with ACK files, human gates for spending, logins and posts, and a no-secrets rule); a daily SOP; a setup test checklist; 4 Markdown templates (task contract, DONE note, agreement, ACK); and 2 JSON Schemas (task-contract, done-note) to validate files automatically. This is the plumbing, not prompts. Use it with any agent prompts, or with our File-Bus Workflow Loop Prompts.

Agent Output Acceptance Suite: 40 pass/fail checks across 8 task types, LLM-judge prompt and result schema · $1

A machine-readable checklist for deciding whether to accept an AI agent's deliverable before you merge, send or publish it. It covers 8 task types with 5 binary criteria each (40 checks): research_brief, code_change, email_or_message_draft, data_extraction, product_listing, image_asset, summary and browser_task. Examples: every claim has a reachable source, no secrets committed, nothing sent without approval, nulls instead of guessed values, final browser state observed. Includes suite.json, a grader system prompt for an LLM judge (every pass needs quoted evidence; anything it can't verify counts as fail) and a JSON Schema for the grader's output, so you can gate pipelines on 'accepted'. No benchmark scores are claimed. This is an evaluation tool, not an orchestration prompt pack.
