What it does

Sonar Coverage is an agent skill from SonarSource/sonarqube-agent-plugins, published by the product's own GitHub organization. Find files with low test coverage and inspect uncovered lines in a SonarQube project (project key optional when MCP integration already defines the default project)

Its SKILL.md is about 2.1k 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 Testing & QA, covering MCP servers and Test coverage. It works with Model Context Protocol and Docker. The repository describes itself as: SonarQube Plugin for AI Agents.

When your agent uses it

  • Tasks that involve MCP servers
  • Tasks that involve Test coverage

Example prompts

  • “/sonar-coverage”

Requirements

  • Docker
  • Pre-approved tools (allowed-tools): Read, Grep, Bash(docker ps:*), Bash(podman ps:*), Bash(nerdctl ps:*), Bash(sonar:*)

Workflow steps

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

  1. Resolve the project key (only when needed)
  2. Parse optional flags from the user-provided arguments
  3. Run the appropriate flow
  4. Next steps

What it can do on your machine

Read from SKILL.md and the folder at commit 6142e57. 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:

    • Read
    • Grep
    • Bash(docker ps:*)
    • Bash(podman ps:*)
    • Bash(nerdctl ps:*)
    • Bash(sonar:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • docker
    • podman

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.

    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

Sonar Coverage loads about 2.1k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 889 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 889 words (~2,052 tokens).

“Identify files with insufficient test coverage and pinpoint the exact lines that need tests.”
