What it does

Eclipse Analyze is an agent skill from gradusnikov/eclipse-chatgpt-plugin. Analyze Java code using Eclipse JDT tools — type hierarchy, find references, call hierarchy, compilation errors, quick fixes, and import suggestions. Use this to understand code structure before making changes.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Codebase onboarding. It works with Java and Model Context Protocol. The repository describes itself as: Eclipse IDE as an MCP Server for AI Agents. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit b789344. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • mcp__eclipse-ide__getClassOutline
    • mcp__eclipse-ide__getMethodSource
    • mcp__eclipse-ide__getFilteredSource
    • mcp__eclipse-ide__getTypeHierarchy
    • mcp__eclipse-ide__findReferences
    • mcp__eclipse-ide__getMethodCallHierarchy
    • mcp__eclipse-ide__getCompilationErrors
    • mcp__eclipse-ide__getQuickFixes
    • mcp__eclipse-ide__getImportSuggestions
    • mcp__eclipse-ide__getJavaDoc

    …and 14 more on the same allowed-tools line.

    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

Eclipse Analyze loads about 1.6k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 625 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

Eclipse Code Analysis

Analyze Java code using Eclipse's JDT (Java Development Tools) infrastructure. These tools provide accurate, compiler-level analysis — not text-based guessing.

Reading Code Efficiently

These tools are designed to minimize context window usage. Follow the outline-first pattern:

  1. getClassOutline — Start here. Returns class declaration, field declarations, method signatures (no bodies), and inner types — all with line numbers and the first sentence of each member's Javadoc (an undocumented override reports its supertype's text, flagged javadocInherited). A 500-line class becomes ~30 lines. Provide fullyQualifiedClassName. Set includeFields=false to omit fields; javadoc=FULL renders whole comments, javadoc=NONE leaves them out.

  2. getMethodSource — After seeing the outline, read only the methods you need. Accepts comma-separated methodNames (e.g., "save,findById,delete"). Returns source with line numbers. Set includeJavadoc=false to skip doc comments. Use methodSignature to disambiguate overloads (e.g., "String" matches methods with a String parameter).

  3. getFilteredSource — Middle ground: returns the full source but collapses methods you don't need to their signatures. Provide methodNames to expand specific methods; all others are shown as one-line signatures with line ranges. Set excludeImports=true (the default) to collapse the import block. Line numbers always match the original file for accurate editing.

  4. getSource — Full source dump. Use only for small classes or when you need everything. Prefer the tools above to save context.

  5. readProjectResource — Read any file by path. Supports startLine/endLine for ranges, showLineNumbers=true for editing, and excludeImports=true to collapse Java import blocks.

Navigation & Understanding

  • getTypeHierarchy — Show supertypes, implemented interfaces, and subtypes for a class.
  • findReferences — Find all usages of a type, method, or field across the workspace. Essential before renaming or deleting.
  • getMethodCallHierarchy — Show callers and callees of a method. Use methodSignature for overloaded methods.
  • getJavaDoc — Rendered Javadoc (Markdown) of a type and each of its members, as the IDE hover shows it, inherited text included. memberName narrows it to one member's overloads; javadoc=SUMMARY gives first sentences only. getTypeHierarchy, searchTypes, searchMethods and getPackageSummary take the same javadoc parameter.
  • explainTypeResolution — Explain source-vs-binary resolution in one project, including classpath root/entry, source attachment, class file, and whether getSource will decompile.
  • gitReadFile — Read a project-relative text file at a Git revision or from INDEX without modifying the working tree.
  • gitDiff — Limit diffs with project-relative pathFilter values and optionally set ignoreWhitespace=true.

Error Analysis

  • getCompilationErrors — Get all compilation errors/warnings. Filter by projectName and severity (ERROR, WARNING, ALL).
  • getQuickFixes — Get available quick fixes for errors in a file. Optionally filter by lineNumber.
  • getImportSuggestions — Find import candidates for unresolved types.

Project Navigation

  • getProjectLayout — File/folder structure. Use scopePath and maxDepth for large projects.
  • getProjectProperties — Java version, source folders, output location, natures.
  • listProjects — All workspace projects with their natures.
  • getProjectDependencies — Maven dependencies for a project.
  • fileSearch — Plain text search across workspace files. Filter with fileNamePatterns.
  • fileSearchRegExp — Regex search across workspace files.
  • findFiles — Find files by glob patterns (e.g., *.xml, pom.xml).

Editor Context

  • getCurrentlyOpenedFile — Get the file currently active in the Eclipse editor.
  • getEditorSelection — Get the currently selected text/lines in the active editor.
  1. Orient: listProjects or getProjectLayout to find what you need
  2. Outline: getClassOutline to understand class structure
  3. Focus: getMethodSource to read specific methods, or getFilteredSource for full-but-collapsed view
  4. Analyze: getTypeHierarchy, findReferences, getMethodCallHierarchy as needed
  5. After edits: getCompilationErrors to verify, then getQuickFixes or getImportSuggestions to resolve
