goldenmatch: Instructions file for Codex

AGENTS.md

goldenmatch AGENTS.md is an instructions file for Codex, OpenCode from benseverndev-oss/goldenmatch. It costs 1,505 tokens per session, scanned A, original, MIT.

Repository instructions for Golden Suite, a monorepo containing tools for matching records that refer to the same entity and for checking data quality. It describes the project layout, supported languages, build process, tests, and known hazards.

In plain words
What is it for?
Use them to navigate the Python, TypeScript, Rust, dbt, and GitHub Actions parts of the project and to learn the relevant build, test, release, and package-specific guidance.
Why use it?
They provide a map of a large multi-language codebase before an agent edits a particular package or shared component.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is benseverndev-oss/goldenmatch's own configuration. It tells Codex and OpenCode how to work on goldenmatch itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything goldenmatch configures →

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

goldenmatch 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 8d 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.

Golden Suite monorepo — agent guide

Fast navigational map for any coding agent. This is the entry point; the deep operational lore (CI internals, incident post-mortems, release/publish mechanics, native-kernel gotchas) lives in CLAUDE.md and the per-package files listed below. Read those before doing package-specific work.

What this is

A polyglot monorepo for entity resolution and data-quality tooling. Six core products, each shipped across multiple language surfaces (Python, a TypeScript port, and pyo3-free Rust -core kernels with optional compiled accelerators). North Star: be the tool a developer reaches for by default for entity resolution — defaults are re-earned every release (context-network/foundation/project-definition.md).

Layout

packages/
  python/        uv workspace — members: packages/python/*
                 (excluded standalone: goldenmatch-kg, goldengraph, golden-suite)
  typescript/    pnpm + Turborepo workspace (TS ports + wasm runtime)
  rust/extensions/  cargo workspace — pyo3-free *-core kernels + *-native accelerators
  actions/       reusable GitHub Actions
  dbt/           dbt models
docs/            design docs, ADRs, specs (docs/superpowers/{specs,plans})
docs-site/       the published docs site (Mintlify)
context-network/ project foundation, decisions, discovery — read for "why"
scripts/         benches, gates, release tooling

Products: goldenmatch (ER core), goldencheck (data-quality scan), goldenflow (transforms), goldenpipe (pipeline compiler), infermap (schema/column mapping), goldenanalysis (cluster/quality analysis). Plus goldengraph (KG engine, standalone) and golden-suite (meta-package).

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.
