agent-stack-template: Instructions file for Codex

AGENTS.md

agent-stack-template AGENTS.md is an instructions file for Codex, OpenCode from krivoox/agent-stack-template. It costs 2,198 tokens per session, scanned A, original, MIT.

A set of project instructions for a production-style multi-tenant web application template, where one application serves multiple organizations or customers. It tells agents how to classify requests and which guides to read.

In plain words
What is it for?
Renaming and adapting the template, choosing the right workflow for a request, and using the included projects feature as a reference before removing it.
Why use it?
It gives agents consistent rules for working in an unfamiliar template and helps prevent them from treating its custom Next.js setup like a standard project.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is krivoox/agent-stack-template's own configuration. It tells Codex and OpenCode how to work on agent-stack-template 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 agent-stack-template configures →

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

agent-stack-template 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 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.

How it starts

The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is NOT the Next.js you know

This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in node_modules/next/dist/docs/ before writing any code. Heed deprecation notices.

Agent guide

Rename this product in src/lib/app-config.ts, package.json and this file. Everything else is already generic.

What this repository is

A production-shaped starting point for a multi-tenant web application, built so that coding agents produce consistent work without being told the same things twice. Conventions live in files an agent reads automatically, not in a person's head.

The included projects feature is a reference vertical slice, not a product. Read it, copy its shape, then delete it.

Every turn

Classify before opening a file. Open one matching guide. Do not read the other playbooks, and do not start from the layer walkthrough until the type is known.

The request is… Do this Do not
A problem, audience or outcome, no spec product-manager → spec Draft write product code
Spec exists but is Draft, or has open questions resolve with the user; domain-architect if the rules are non-trivial write product code
Spec Accepted or Shipped, new behaviour with a domain rule new-feature.md skip the spec
Spec Accepted or Shipped, new behaviour with no domain rule (wiring, copy, layout only) new-feature.md, skip domain tests and domain/ invent a domain/ function so TDD has a target
Spec and code disagree say which is wrong; fix that one invent a third rule
Current behaviour is wrong bugfix.md start a feature
Same behaviour, new shape refactor.md change a spec rule
Tooling, deps, CI, env, docs-only chore.md sneak in behaviour; write a domain test
Copy, layout, existing actions ui-ux-developer put rules in React; TDD the markup
Infra, migrations, deploy, secrets devops-engineer run destructive commands unasked
The change does not touch domain/ and adds no business rule TDD does not apply. npm run verify is the gate invent a test or a domain wrapper

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.
