ASSERT AGENTS.md

Repository instructions for ASSERT, a local-first test system where written evaluation specifications become test cases for judging AI-agent behavior.

In plain words
What is it for?
Use them when writing evaluation specifications, generating cases, running targets, judging conversations or actions, or handling evaluation artifacts.
Why use it?
They provide the approved terminology, workflow, privacy rules, and source files so changes remain safe and consistent with the customer-facing preview.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ASSERT AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 327 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Adaptive Eval Agent Orientation

This file is for coding assistants such as GitHub Copilot, Claude Code, Cursor, and similar tools. It gives a short, customer-safe map of this preview repository.

What this repo is

Adaptive Eval is a local-first, spec-driven evaluation harness for AI agents. A developer writes an eval spec, the pipeline generates targeted test cases, runs them against a target, and judges the resulting inference outputs (conversations or agent actions) against the spec.

Use this mental model:

eval spec -> behavior categories -> test cases -> execute target -> judge -> artifacts

Safety and privacy rules

  • Never read, print, commit, summarize, or infer values from .env or other local environment files.
  • Use placeholder names such as AZURE_API_KEY, AZURE_API_BASE, azure_ad_token, and azure_ad_token_provider; never invent or expose credential values.
  • Do not recommend committing generated artifacts, local traces, .venv, logs, or .env files.
  • Treat this repo as a customer-preview distribution. Keep contributions customer-safe — avoid any internal-only planning, prioritization, or organizational content.

Authoritative files

Start with these files:

  • README.md - customer-facing overview and quickstart.
  • docs/quickstart.md - LangGraph travel planner walkthrough.
  • docs/targets/README.md - target decision tree (rendered by default when browsing docs/targets/).
  • docs/targets/callable.md - Python callable target for any agent or multi-agent system, with OpenTelemetry trace capture as the recommended integration path.
  • docs/targets/model-and-tools.md - Prompt Agent target (hosted model + system prompt + optional tool schema; runtime owns the tool-call loop).
  • docs/config/schema.md - current YAML schema reference.
  • examples/README.md - example selection guide.

Current preview terminology

Use the developer-friendly behaviors in prose, and mention current YAML keys when needed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
