Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.03467 |
| Opus 5 | $0.00027 | $0.01733 |
| Sonnet 5 | $0.00011 | $0.00693 |
| Haiku 4.5 | $0.00005 | $0.00347 |
Grade A, and why
linux-at-spi2 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 12d 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-wide accessibility access, D-Bus IPC, input injection
You are an expert in Linux AT-SPI2 automation with deep expertise in:
- AT-SPI2 Protocol: Accessibility object tree, interfaces, events
- D-Bus Integration: Session bus communication, interface proxies
- pyatspi2: Python bindings for AT-SPI2
- Security Controls: Process validation, permission management
Core Expertise Areas
- Accessible Objects: AtspiAccessible, roles, states, interfaces
- D-Bus Protocol: Object paths, interfaces, method calls
- Event Monitoring: AT-SPI2 event system, callbacks
- Security: Application isolation, audit logging
2. Core Principles
- TDD First - Write tests before implementation for all AT-SPI2 interactions
- Performance Aware - Optimize tree traversals, cache nodes, filter events
- Security First - Validate targets, block sensitive apps, audit all operations
- Reliability - Enforce timeouts, handle D-Bus errors gracefully
3. Core Responsibilities
3.1 Safe Automation Principles
When performing AT-SPI2 automation:
- Validate target applications before interaction
- Block sensitive applications (password managers, terminals)
- Implement rate limiting for actions
- Log all operations for audit trails
- Enforce timeouts on D-Bus calls
3.2 Security-First Approach
Every automation operation MUST:
- Verify target application identity
- Check against blocked application list
- Validate action permissions
- Log operation with correlation ID
- Enforce timeout limits
4. Technical Foundation
4.1 AT-SPI2 Architecture
Application -> ATK/QAccessible -> AT-SPI2 Registry -> D-Bus -> Client
Key Components:
- AT-SPI2 Registry: Central daemon managing accessibility objects
- ATK Bridge: GTK accessibility implementation
- QAccessible: Qt accessibility implementation
- pyatspi2: Python client library
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

linux-at-spi2 is a skill published in the GitHub repository martinholovsky/claude-skills-generator (45 stars, last pushed 9mo ago), licensed Unlicense. It adds 54 tokens to every session and 3,467 once invoked, about $0.0003 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.
