  • Explicit requests: explore project

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Spring Explore is an agent skill from Amplicode/spring-skills. Explores a Spring Boot application and builds primary context: tech stack, module structure, domain entities, REST endpoints. Triggers on explicit requests: "explore project", "describe project", "project overview", "what is this project", "project structure", "tech stack", "give me context about the project", or whenever you need to understand the project before starting any task.

Its SKILL.md is about 4.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `references/ddd-model-based-on-jpa.md`, `references/deep-model-based-on-jpa.md` and `references/entity-components.md`).

It sits in Backend & APIs, covering Backend development, REST APIs and MCP servers. It works with Spring Boot, Model Context Protocol and JetBrains IDEs. The repository describes itself as: Amplicode Agent Tools.

When your agent uses it

  • Explicit requests: explore project
  • Describe project
  • Project overview
  • What is this project

Example prompts

  • “explore project”
  • “describe project”
  • “project overview”
  • “/spring-explore”

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Predict involvement from the user's request
  2. Define exploration goal and select paths
  3. Load references
  4. Build unified exploration plan
  5. Execute exploration plan via subagent
  6. Build exploration report
  7. 5 — Formulate implicit assumptions
  8. Decide on next cycle

What it can do on your machine

Read from SKILL.md and the folder at commit bf19b3c. 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

    Links to these hosts (documentation or services it may open):

    • amplicode.ru

    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

Spring Explore loads about 4.1k tokens when it runs, and up to ~8.8k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 1,408 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.8k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,408 words (~4,058 tokens).

“This skill is part of the Spring Agent Toolkit and is designed to work with the Spring MCP server (provided by the Amplicode IntelliJ plugin). Before doing anything else, check your tool list for any Spring MCP tool — they…”
