fix-sonar-issues

fix-sonar-issues is a skill for Claude Code, Codex from vepo/issues. It costs 33 tokens per session (457 once invoked), scanned A, original, Apache-2.0.

A local static-analysis maintenance skill for Java projects. Static analysis checks source code for compiler warnings, reliability problems, and maintainability issues without running the application.

In plain words
What is it for?
Use it to compile the project, inspect diagnostics, and repair issues such as empty exception handlers, debug output, unused code, deprecated APIs, and duplicated literals.
Why use it?
It fixes common code-quality findings while preserving behavior and avoiding any connection to SonarCloud or its credentials.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fix-sonar-issues scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are an expert Java developer working on Issues. Fix all issues surfaced by local static analysis — the same class of problems SonarCloud flags, without calling SonarCloud or using any token.

Align with .cursor/rules/static-analysis.mdc: local checks only.

Follow this loop — do not ask for confirmation before editing.

1. Discover issues (local)

mvn -B compile -Dmaven.compiler.showWarnings=true -Dmaven.compiler.showDeprecation=true

Scan IDE diagnostics: ReadLints on changed src/main/java and src/test/java.

Do not call SonarCloud API.

2. Prioritize

  1. Compile errors, failing verify
  2. Reliability smells: empty catches, System.out, printStackTrace
  3. Compiler + linter warnings: unused code, deprecations
  4. Maintainability: cognitive complexity, duplicated literals

3. Fix strategies

Theme Safe approach Avoid
Unused imports / dead code Remove after confirming zero references Deleting public API
Exception handling SLF4J + rethrow or IssuesException Empty catch
Test smells Fix assertion or setup @Disabled, weakened assertions
HTTP contract Use *Request/*Response records VO/DTO suffix

Never: weaken workflow validation; delete tests to green CI.

4. Verify each batch

mvn formatter:format
mvn -B verify

5. Log every change

Append to reports/sonar_fix_log-{sequential}-{dd-MM-yyyy-HH-mm-ss}.md.

6. Stop when

  • mvn verify passes
  • ReadLints clean on touched files

Print ✅ Local static analysis clean! and summarize.

Start the loop now.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fix-sonar-issues is a skill published in the GitHub repository vepo/issues (8 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 457 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
