At a glance

Refactoring using Remove Parameter in Java Language. An agent skill from github/awesome-copilot.

  • Tasks that involve Refactoring
  • SKILL.md covers Role, Code Before Refactoring 1:, Code After Refactoring 1: and Code Before Refactoring 2:, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Java Refactoring Remove Parameter is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Refactoring using Remove Parameter in Java Language

Its SKILL.md is about 740 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 Development, covering Refactoring. It works with Java. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Tasks that involve Refactoring

Example prompts

  • “/java-refactoring-remove-parameter”

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. 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 (its code samples are java).

    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

Java Refactoring Remove Parameter loads about 738 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 181 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~738

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.

Refactoring Java Methods with Remove Parameter

Role

You are an expert in refactoring Java methods.

Below are 2 examples (with titles code before and code after refactoring) that represents Remove Parameter.

Code Before Refactoring 1:

java
public Backend selectBackendForGroupCommit(long tableId, ConnectContext context, boolean isCloud)
        throws LoadException, DdlException {
    if (!Env.getCurrentEnv().isMaster()) {
        try {
            long backendId = new MasterOpExecutor(context)
                    .getGroupCommitLoadBeId(tableId, context.getCloudCluster(), isCloud);
            return Env.getCurrentSystemInfo().getBackend(backendId);
        } catch (Exception e) {
            throw new LoadException(e.getMessage());
        }
    } else {
        return Env.getCurrentSystemInfo()
                .getBackend(selectBackendForGroupCommitInternal(tableId, context.getCloudCluster(), isCloud));
    }
}

Code After Refactoring 1:

java
public Backend selectBackendForGroupCommit(long tableId, ConnectContext context)
        throws LoadException, DdlException {
    if (!Env.getCurrentEnv().isMaster()) {
        try {
            long backendId = new MasterOpExecutor(context)
                    .getGroupCommitLoadBeId(tableId, context.getCloudCluster());
            return Env.getCurrentSystemInfo().getBackend(backendId);
        } catch (Exception e) {
            throw new LoadException(e.getMessage());
        }
    } else {
        return Env.getCurrentSystemInfo()
                .getBackend(selectBackendForGroupCommitInternal(tableId, context.getCloudCluster()));
    }
}

Code Before Refactoring 2:

java
NodeImpl( long id, long firstRel, long firstProp )
{
     this( id, false );
}

Code After Refactoring 2:

java
NodeImpl( long id)
{
     this( id, false );
}

Task

Apply Remove Parameter to improve readability, testability, maintainability, reusability, modularity, cohesion, low coupling, and consistency.

Always return a complete and compilable method (Java 17).

Perform intermediate steps internally:

  • First, analyze each method and identify parameters that are unused or redundant (i.e., values that can be obtained from class fields, constants, or other method calls).
  • For each qualifying method, remove the unnecessary parameters from its definition and from all its internal calls.
  • Ensure that the method continues to function correctly after parameter removal.
  • Output only the refactored code inside a single java block.
  • Do not remove any functionality from the original method.
  • Include a one-line comment above each modified method indicating which parameter was removed and why.

Code to be Refactored:

Now, assess all methods with unused parameters and refactor them using Remove Parameter
