ekbatan: Skill for Codex

.agents/skills/ekbatan-examples/SKILL.md

ekbatan-examples is a skill for Codex from ekbatan-io/ekbatan. It costs 69 tokens per session (494 once invoked), scanned A, original, Apache-2.0.

A maintenance guide for example applications covering several Java frameworks, build systems, databases, and runtime variants.

In plain words
What is it for?
Use it when adding, updating, auditing, or verifying examples across Spring Boot, Quarkus, Micronaut, Gradle, Maven, relational databases, native images, sharding, sagas, or job workers.
Why use it?
It helps prevent changes in one example from making related examples inconsistent or using the wrong database or framework setup.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is ekbatan-io/ekbatan's own configuration. It tells Codex how to work on ekbatan 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 ekbatan 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

ekbatan-examples 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 10d 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.

What it actually says

Ekbatan Examples

Use this skill when a change affects example applications, example docs, example wiring, or consistency across the example matrix.

First Reads

  • ekbatan-examples/README.md.
  • The closest existing example for the same stack/build/dialect.
  • references/example-matrix.md.
  • Relevant framework docs under docs/wiring/, docs/database/, and docs/runtime/.

Matrix Discipline

When changing a base wallet behavior, check every affected axis:

  • Stack: Spring Boot, Quarkus, Micronaut.
  • Build: Gradle, Maven.
  • Dialect: PostgreSQL, MySQL, MariaDB.
  • Runtime: JVM and native-named examples.
  • Special cases: sharded PostgreSQL, saga, job worker.

Do not assume examples are generated unless you find a generator. Use rg and compare representative files directly.

Common Patterns

  • Keep domain/action/repository code semantically identical across stacks unless the stack requires wiring differences.
  • Keep dialect-specific provider classes correct: PostgreSQL uses PostgreSQL providers, MySQL uses MySQL providers, MariaDB uses MariaDB providers.
  • For action write serialization, acquire KeyedLockProvider in the caller around the full executor.execute(...) call.
  • Keep native examples aligned with their JVM equivalents unless native-image support requires a specific difference.
  • Keep README claims backed by source search.
  • Avoid updating generated or build output.

Workflow

  1. Identify the affected projects with find ekbatan-examples -mindepth 2 -maxdepth 2.
  2. Inspect one known-good example for each stack and dialect family before editing.
  3. Make the smallest mechanical cross-matrix edit possible.
  4. Run formatters for affected builds.
  5. Run representative compiles/tests first, then broader example verification when behavior is cross-cutting.
  6. If docs claim "all examples", prove it with rg or a small matrix script.

Use ekbatan-verification for the full example test matrix.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
