sonar-review

sonar-review is a skill for Claude Code from sananthanarayan/skilldrop. It costs 217 tokens per session (4,034 once invoked), scanned A, original, MIT.

A code-review skill that scans recently changed files with Sonar, a code-quality analysis tool, and produces a structured report with a quality-gate result and severity levels.

In plain words
What is it for?
Use it before merging changes to check changed files for Sonar findings, including bugs, security concerns, and maintainability problems.
Why use it?
It turns scanner output into an actionable pre-merge review, showing which changed lines have reported issues and which Sonar rules apply.

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

sonar-review scanned grade A with 1 finding 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sonar-review

You run a Sonar scan against the user's just-changed code and produce a structured pre-merge compliance report. The artifact is a markdown review the user acts on — not raw scanner output, not a quiet "scan complete".

This skill is the Sonar-flavored counterpart to devils-advocate: same shape (severity-tagged findings, file:line evidence, concrete fixes, verdict on top), but the rules come from Sonar's catalog and the verdict comes from the project's quality gate, not your judgment.

Works against both deployment modes — the mode is detected from sonar-project.properties, not asked:

Mode Detection Host Token env
SonarQube server No sonar.organization line $SONAR_HOST_URL (set by user) $SONAR_TOKEN
SonarCloud sonar.organization=<key> present https://sonarcloud.io (fixed) $SONAR_TOKEN

The API endpoints are identical between the two — only the host differs. If the user is jumping in cold and the repo isn't wired up, run sonar-onboard first.

How to respond

  1. Detect the mode. First thing — read sonar-project.properties and check for a sonar.organization= line:

    • Present ⇒ SonarCloud. Host is https://sonarcloud.io (don't read $SONAR_HOST_URL).
    • Absent ⇒ SonarQube server. Host comes from $SONAR_HOST_URL.

    Use the detected mode for every subsequent step. Don't ask the user — the properties file is the source of truth.

  2. Verify the environment before scanning. Checks differ by mode:

    Check Applies to If missing
    sonar-project.properties at repo root both Stop. Tell the user to run sonar-onboard first — there's no project config to scan against.
    sonar-scanner on PATH both Stop. Print the install hint (see step 3). Do not attempt to install it.
    SONAR_TOKEN env var set both Stop. Tell the user to export it from their Sonar account → Security → Tokens.
    SONAR_HOST_URL env var set server only Stop. Tell the user to export it (e.g. export SONAR_HOST_URL=https://sonar.company.com).

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.
