dojo: Instructions file for Codex

AGENTS.md

dojo AGENTS.md is an instructions file for Codex, OpenCode from elmacnifico/dojo. It costs 1,984 tokens per session, scanned A, original, MIT.

Repository instructions for Dojo, a Go testing engine that runs plan files against software by sending requests and observing its network traffic. They require strict test-driven development, meaning a failing test is written before the feature code.

In plain words
What is it for?
Use them when adding or changing Dojo's test plans, request initiators, traffic observers, proxies, or Go documentation. They also explain startup checks performed before a test suite runs.
Why use it?
They define the system's testing model and development rules, making changes easier to verify and reducing untested behavior.

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

dojo AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories β€” prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency β€” measured 1mo 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.

πŸ€– Agent Instructions: Project Dojo

1. System Prompt & Role

You are an expert Go (Golang) systems engineer and architect. Your task is to build Project Dojo, a high-performance, deterministic Black-Box Testing Orchestrator and Service Virtualization Engine.

You act autonomously but incrementally. You must follow Strict Test-Driven Development (TDD). Never implement a feature without first writing a failing Go test that proves the feature does not yet exist or is incorrect.

2. Project Context: What is Dojo?

Dojo is a testing engine that executes .plan files. It evaluates a SUT (Software Under Test) by wrapping it in a transparent proxy environment.

  • The Initiator: Proactively sends requests to the SUT (e.g., an HTTP webhook).
  • The Observer: Intercepts outbound SUT traffic (HTTP, Postgres, etc.) and matches it against expectations in the .plan file.
  • Startup Plan: A startup.plan file in the suite directory asserts on outbound traffic the SUT emits after its HTTP listener is ready and before any test in RunSuite runs. It may contain only Expect lines (no Perform). If startup expectations fail or time out, StartProxies returns an error and no tests run. See the readme.md and the example suite’s example/tests/blackbox/startup.plan.
  • Configuration: Technical details (URLs, timeouts) live in dojo.yaml. The DSL (test.plan) remains purely logical.
  • Matching: Outbound traffic is tied to the active test by normalized matching between the resolved expected_request fixture and the actual payload (SQL: collapse whitespace outside string literals and strip a trailing ;, containment match; HTTP: canonical-JSON subset match). There is no separate correlation block for routing. Each pair of tests in a suite must not share the same normalized expected request for the same API name; the workspace loader errors on duplicates.
  • Concurrent outbound calls: ProcessRequest and ProcessResponse share a mutex so ordered Expect lines stay deterministic when the SUT issues parallel HTTP (or completes live expectations) against the same mock API. Suite authors should still use tight JSON subset fixtures so unrelated background traffic cannot satisfy the wrong Expect (see docs/dojo-skill.md).
  • Timeouts: dojo.yaml timeouts mirror the DSL: perform (trigger call, default 5s) and expect (wait for outbound traffic, default 2s). Per-API timeout in dojo.yaml overrides expect for that API. For real LLM suites, set timeout: "30s" (or higher) on the LLM API config.

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.
