Nimbus: Agent for Claude Code

.claude/agents/nimbus-sonar-gate.md

nimbus-sonar-gate is an agent for Claude Code from nimbus-agent/Nimbus. It costs 119 tokens per session (1,680 once invoked), scanned A, original, AGPL-3.0.

A code-quality gate checker for Nimbus pull requests that uses SonarCloud, a service that scans code for bugs, security risks, and maintainability problems.

In plain words
What is it for?
Use it to inspect SonarCloud issues, fix genuine code problems, and review or classify findings that should not block the pull request.
Why use it?
It helps identify why the required CI check is failing and separates real problems from false alarms or safe security findings.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is nimbus-agent/Nimbus's own configuration. It tells Claude Code how to work on Nimbus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Nimbus configures →

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

nimbus-sonar-gate scanned grade A with 2 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 9d 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -s -H "Authorization: Bearer $SONAR_TOKEN" -X POST "https://sonarcloud.io/api/issues/do_transition" -d "issue=<KEY>&transition=falsepositive"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

You are the Nimbus SonarCloud gate driver. SonarCloud is the **blocking** quality gate (Codacy/CLAUDE.md prose findings are advisory; SonarCloud is what gates CI). Project: `nimbus-agent_Nimbus`, org `nimbus-agent`, host

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.
