A repository-wide instruction guide for go-authcrunch, a Go library that provides authentication, authorization, and accounting features. It describes the project structure, important packages, scripts, coding rules, and testing guidance.

In plain words
What is it for?
Use it as the general starting point when working anywhere in the go-authcrunch repository, especially when locating authentication, identity, authorization, UI, or command-line code.
Why use it?
It gives coding agents the shared context needed to make changes in the right package and follow the repository's established rules.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads ~/.codex paths; mentions Codex.

This is greenpau/go-authcrunch's own configuration. It tells Codex and OpenCode how to work on go-authcrunch 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 go-authcrunch 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

go-authcrunch 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 28d 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.

Repository Guidelines

Project Summary

go-authcrunch is a Go library for AuthCrunch Authentication, Authorization, and Accounting (AAA) security functions. It provides the core runtime used for authentication portals, authorization gatekeepers, identity stores, identity providers, single sign-on providers, user registration, messaging, credentials, and cryptographic key handling.

The top-level authcrunch.Config and Server wire together the repository's major packages. Authentication portal behavior lives mostly under pkg/authn, authorization policy and gatekeeper behavior under pkg/authz, identity store dispatch under pkg/ids, identity provider dispatch under pkg/idp, local and LDAP stores under pkg/ids/local and pkg/ids/ldap, OAuth and SAML providers under pkg/idp/oauth and pkg/idp/saml, and crypto key management under pkg/kms.

The repository also includes the standalone authdb HTTP server in cmd/authdb, the authdbctl management CLI in cmd/authdbctl, embedded portal/profile UI assets under pkg/authn/ui, shared identity and user data models under pkg/identity, user registration under pkg/registry, messaging providers under pkg/messaging, i18n helpers under pkg/translate, and test fixtures under testdata. Canonical HTTP API YAML and the Scalar reference live in assets/openapi/; cmd/openapi and internal/openapi own validation, generated JSON and the local reference server.

Scripts and Automation

Use scripts-and-automation to choose, run, or document Makefile targets, repository scripts, build/test/report workflows, generated artifacts, dependency automation, or release/version procedures.

HTTP-facing changes must evaluate the YAML contract in the same change; the scripts router delegates this workflow to openapi-generation.

make test uses pinned tested; make ci-check is the complete quality gate. make release, make minor-release, make fast-release, and make fast-minor-release publish commits and tags and are only run when an actual release is requested.

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.
