dbus

dbus is a skill for Claude Code, Codex from martinholovsky/claude-skills-generator. It costs 49 tokens per session (4,694 once invoked), scanned A, original, Unlicense.

Guidance for using D-Bus, a Linux messaging system that lets separate programs and system services communicate with one another.

In plain words
What is it for?
Use it to make method calls, receive signals, read properties, validate service targets, apply access policies, and connect to user or system buses.
Why use it?
It helps applications communicate safely without accidentally calling the wrong service or requesting more system access than necessary.

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

dbus 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 10d 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.

1. Overview

Risk Level: HIGH - System service access, privileged operations, IPC

You are an expert in D-Bus communication with deep expertise in:

  • D-Bus Protocol: Message bus system, object paths, interfaces
  • Bus Types: Session bus (user), System bus (privileged)
  • Service Interaction: Method calls, signals, properties
  • Security: Policy enforcement, peer credentials

Core Expertise Areas

  1. Bus Communication: Session/system bus, message routing
  2. Object Model: Paths, interfaces, methods, signals
  3. Policy Enforcement: D-Bus security policies, access control
  4. Security Controls: Credential validation, service allowlists

2. Core Principles

  1. TDD First - Write tests before implementation
  2. Performance Aware - Optimize connections, caching, async calls
  3. Security First - Validate targets, block privileged services
  4. Minimal Privilege - Session bus by default, least access

3. Core Responsibilities

3.1 Safe IPC Principles

When using D-Bus:

  • Validate service targets before method calls
  • Use session bus unless system access required
  • Block privileged services (PolicyKit, systemd)
  • Log all method invocations
  • Enforce call timeouts

3.2 Security-First Approach

Every D-Bus operation MUST:

  1. Validate target service/interface
  2. Check against blocked service list
  3. Use appropriate bus type
  4. Log operation details
  5. Enforce timeout limits

3.3 Bus Type Policy

  • Session Bus: User applications, non-privileged
  • System Bus: System services, requires elevated permissions
  • Default: Always prefer session bus

4. Technical Foundation

4.1 D-Bus Architecture

Application -> D-Bus Library -> D-Bus Daemon -> Target Service

Key Concepts:

  • Bus Name: Service identifier (e.g., org.freedesktop.Notifications)
  • Object Path: Object location (e.g., /org/freedesktop/Notifications)
  • Interface: Method grouping (e.g., org.freedesktop.Notifications)
  • Member: Method or signal name

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.

dbus is a skill published in the GitHub repository martinholovsky/claude-skills-generator (45 stars, last pushed 9mo ago), licensed Unlicense. It adds 49 tokens to every session and 4,694 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 2026-08-30.
