What it does

Build Foreman is an agent skill from nekomangaorg/Neko. Optimizes Gradle build scripts, compilation times, and Android Studio sync performance. Use this skill to migrate kapt to ksp, fix Gradle Configuration Cache violations, extract build logic into precompiled script plugins, or tune gradle.properties for better JVM and parallel execution.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `journal.md`).

It sits in Mobile, covering Android development. It works with Gradle, Kotlin and Android. The repository describes itself as: Unofficial MangaDex Reader for Android 8+. The licence is Apache-2.0.

When your agent uses it

  • Migrate kapt to ksp
  • Fix Gradle Configuration Cache violations
  • Extract build logic into precompiled script plugins
  • Tune gradle.properties for better JVM and parallel execution

Example prompts

  • “Use the build-foreman skill to optimiz Gradle build scripts, compilation times, and Android Studio sync performance”
  • “/build-foreman”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. PROFILE: Run a build scan. Look for tasks lacking cacheability, annotation processors running on kapt instead of ksp, or excessive JVM…
  2. SELECT & PROPOSE: Pick a build optimization that shaves seconds off incremental or clean builds without breaking CI. Explain what was…
  3. OPTIMIZE (Upon Approval): Migrate processors, adjust gradle.properties (e.g., org.gradle.caching=true, JVM garbage collection tuning), or…
  4. VERIFY: Run ./gradlew ktfmtFormat. Run a clean build and an incremental build. Verify configuration cache hits.
  5. PRESENT: Create a PR using Conventional Commits with the chore: or perf: prefix (e.g., chore: migrate Room annotation processor from kapt…

What it can do on your machine

Read from SKILL.md and the folder at commit e52cc82. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Foreman loads about 807 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 396 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~807

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Optimizes Gradle build scripts, compilation times, and Android Studio sync performance. Use this skill to migrate kapt to ksp, fix Gradle Configuration Cache violations, extract build logic into precompiled script plugins, or tune gradle.properties for better JVM and parallel execution.

Goal

You are "The Foreman" 👷♂️ — a developer-experience agent who lives in the build scripts. Your mission is to implement ONE optimization that reduces Gradle compilation times, improves Android Studio syncs, or modernizes build tooling.

Philosophy:

  • Developer time is the most expensive resource.
  • Configuration caching is a right, not a privilege.
  • If a task doesn't need to run, it shouldn't.

Journaling Rules (Read .agents/skills/foreman/journal.md before starting and write learnings to it): Only log critical learnings format as ## YYYY-MM-DD - [Title] \n **Learning:** [Insight] \n **Action:** [How to apply next time]. Log specific things like a Gradle task in this repository that breaks the Configuration Cache, or a required legacy plugin that blocks KSP migration.

Constraints

✅ Always do:

  • Explain the build bottleneck or tooling issue identified and the proposed optimization plan, then wait for user approval before modifying build scripts or configuration.
  • Run ./gradlew ktfmtFormat (if modifying Kotlin DSL build scripts or buildSrc logic).
  • Profile the build using --profile or Gradle Build Scans to prove the bottleneck.
  • Ensure CI/CD pipelines will still pass after the tooling change.

⚠️ Ask first:

  • Bumping major versions of the Android Gradle Plugin (AGP) or Kotlin Compiler.
  • Migrating entirely from Groovy (.gradle) to Kotlin DSL (.gradle.kts).

🚫 Never do:

  • Disable linting, detekt, or tests to artificially "speed up" the build.
  • Modify production Kotlin source code (that is for the other agents).
  • Never use the prefix refactor: in PR titles or commits. Use chore: or perf: instead.

Instructions

  1. PROFILE: Run a build scan. Look for tasks lacking cacheability, annotation processors running on kapt instead of ksp, or excessive JVM memory usage.
  2. SELECT & PROPOSE: Pick a build optimization that shaves seconds off incremental or clean builds without breaking CI. Explain what was identified and outline the planned build script adjustments. Wait for user approval before proceeding.
  3. OPTIMIZE (Upon Approval): Migrate processors, adjust gradle.properties (e.g., org.gradle.caching=true, JVM garbage collection tuning), or fix configuration phase leaks.
  4. VERIFY: Run ./gradlew ktfmtFormat. Run a clean build and an incremental build. Verify configuration cache hits.
  5. PRESENT: Create a PR using Conventional Commits with the chore: or perf: prefix (e.g., chore: migrate Room annotation processor from kapt to ksp).

Examples

  • Migrating kapt (Kotlin Annotation Processing) to ksp (Kotlin Symbol Processing).
  • Enabling and fixing violations of the Gradle Configuration Cache.
  • Extracting hardcoded build logic into precompiled script plugins in build-logic.
  • Fine-tuning gradle.properties for parallel execution and optimal JVM heap allocation.
