At a glance

A skill your agent uses when you need to generate a checklist document with Java system prompts from skills.xml, following the embedded section template and producing INVENTORY-SKILLS-JAVA.md.

  • You need to generate a checklist document with Java system prompts from skills.xml
  • SKILL.md covers Constraints, When to use this skill, Workflow and Reference
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Following the embedded section template and producing INVENTORY-SKILLS-JAVA.md

What it does

003 Skills Inventory is an agent skill from jabrena/plinth. Use when you need to generate a checklist document with Java system prompts from skills.xml, following the embedded section template and producing INVENTORY-SKILLS-JAVA.md. This should trigger for requests such as Create Java system prompts checklist; Generate INVENTORY-SKILLS-JAVA.md; Use @003-skills-inventory; Inventory Java cursor rule skills; List available Java system prompt skills. Part of Plinth Toolkit

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files and assets (for example `assets/java-skills-inventory-template.md` and `references/003-skills-inventory.md`).

It sits in AI & LLM Engineering, covering Prompt engineering and Agent instruction files. It works with Java. The repository describes itself as: Plinth is an AI-native engineering toolkit for modern Java enterprise SDLC, built around reusable Commands, Agents, Skills, and MCP Servers. The licence is Apache-2.0.

When your agent uses it

  • You need to generate a checklist document with Java system prompts from skills.xml
  • Following the embedded section template and producing INVENTORY-SKILLS-JAVA.md
  • Requests such as Create Java system prompts checklist
  • Generate INVENTORY-SKILLS-JAVA.md

Example prompts

  • “/003-skills-inventory”

What it can do on your machine

Read from SKILL.md and the folder at commit dca88dc. 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

003 Skills Inventory loads about 792 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 109 tokens; SKILL.md has 339 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~792
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

Create a Checklist with all Java steps to use with system prompts for Java

Create a comprehensive step-by-step checklist document for Java system prompts by following the embedded section template and deriving rows from plinth-skills-generator/src/main/resources/skills.xml.

What is covered in this Skill?

  • Inventory-driven checklist generation
  • Output file creation as INVENTORY-SKILLS-JAVA.md
  • Strict coverage of every effective skill id declared in skills.xml

Constraints

Follow the template sections exactly and use skills.xml as the single source of truth for skill rows.

  • DO NOT create additional sections beyond what the template defines
  • DO NOT add skill rows absent from skills.xml
  • DO NOT omit any skill declared in skills.xml
  • ONLY use the skillId attribute as the generated skill id when it exists
  • ONLY use the single reference-list/reference value as the generated skill id when skillId is absent
  • EDGE CASE: If the user goal is ambiguous, stop and ask a clarifying question before editing files or running project-wide commands
  • EDGE CASE: If required context, files, credentials, or tools are missing, report the blocker explicitly and ask whether to proceed with setup or fallback guidance
  • EDGE CASE: If requested changes conflict with project constraints or safety boundaries, explain the conflict and ask for user confirmation on the preferred trade-off

When to use this skill

  • Create Java system prompts checklist
  • Generate INVENTORY-SKILLS-JAVA.md
  • Use @003-skills-inventory
  • Inventory Java cursor rule skills
  • List available Java system prompt skills

Workflow

  1. Read the template and inventory source

Read references/003-skills-inventory.md and plinth-skills-generator/src/main/resources/skills.xml before generating output.

Step constraints:

  • Do not use cached or remembered template content
  • Preserve exact section structure from the reference
  • Use skillId when present; otherwise use the single reference name
  1. Generate inventory document

Create INVENTORY-SKILLS-JAVA.md at the requested output path, or in the project root when no explicit path is requested, with one row for every effective skill id declared in skills.xml.

  1. Validate inventory coverage

Verify that the generated file contains every effective skill id from skills.xml, contains no extra skill rows, and preserves all expected sections from the reference.
