kotlin-app-template: Instructions file for Codex

AGENTS.md

kotlin-app-template AGENTS.md is an instructions file for Codex, OpenCode from ashtanko/kotlin-app-template. It costs 944 tokens per session, scanned A, original, Apache-2.0.

A repository guide for a Kotlin template project. It explains where to find task-specific instructions, how to build the project, which Kotlin and Java versions to use, and which files control dependencies and coding rules.

In plain words
What is it for?
Use it when developing in this Kotlin and Gradle repository, especially for choosing commands, versions, files, and task-specific guidance.
Why use it?
It prevents agents from treating example code as a real product and from using incompatible tools, language features, or dependency settings.

Instructions file for CodexOpenCode

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

This is ashtanko/kotlin-app-template's own configuration. It tells Codex and OpenCode how to work on kotlin-app-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 kotlin-app-template 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

kotlin-app-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 7d 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 agent guide

This file is the canonical entry point for coding agents working in this repository.

Start here

  • Read .agents/README.md for the task-specific context map.
  • Load only the relevant reference or skill; don't pull every agent document into context at once.
  • See CLAUDE.md for how the repo operates — build, commands, tooling pipeline, generated README, centralized versions, CI, git hooks, PR mechanics. This file and .agents/ own how to write the code. The two don't duplicate each other.
  • This is a GitHub template repo, not a product: the code under src/main/kotlin/dev/shtanko/template/ (Calculator, DataProcessor, DivideByZeroException) is placeholder/example code that demonstrates the toolchain, not a feature to preserve as-is.

Repository rules

  • Use the Gradle wrapper (./gradlew); target JDK 17+ (CI builds on 17 and 21).
  • Kotlin language level is pinned to KOTLIN_2_2 in build.gradle.kts even though the Kotlin plugin/compiler is 2.4.0 — don't use language features newer than 2.2.
  • Keep dependency and plugin versions in gradle/libs.versions.toml; don't hardcode versions elsewhere.
  • Formatting, import order, and license headers are enforced by tooling (spotless, detekt, ktlint, diktat). Run ./gradlew spotlessApply / make check rather than hand-formatting — see .agents/reference/commands.md.
  • Don't edit generated output (build/, README.md's body, config/detekt/detekt-baseline.xml) unless the task explicitly requires it. README.md is generated from config/main.md — edit that instead and run make md.
  • Preserve unrelated work in a dirty worktree. Inspect the diff before editing and never clean up changes you did not make.

Working method

  1. Inspect the target file, its neighboring examples, and the current diff before editing.
  2. Make the smallest coherent change that follows the existing package and file conventions — mirror the canonical example files listed in .agents/reference/coding-conventions.md.
  3. Add or update tests with behavior changes, following .agents/reference/testing.md.
  4. Run the narrowest useful check first, then broaden in proportion to the change — see .agents/reference/commands.md. Run make check && make test before finishing.
  5. Report changed files, checks run, and anything not verified. Never claim a check passed if it was not run.

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.
