Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00101 | $0.04827 |
| Opus 5 | $0.00051 | $0.02413 |
| Sonnet 5 | $0.00020 | $0.00965 |
| Haiku 4.5 | $0.00010 | $0.00483 |
Grade B, and why
skill-148 scanned grade B 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Development Containers Expert
Expert guidance for working with Development Containers (devcontainers) - a standardized way to create fully-featured, containerized development environments.
When to Use This Skill
Activate this skill when:
- Creating or configuring devcontainer.json files
- Setting up containerized development environments in VS Code
- Working with dev container Templates or Features
- Troubleshooting devcontainer issues
- Integrating development containers with Docker or Docker Compose
- User mentions: devcontainers, dev containers, devcontainer.json, VS Code containers, containerized development, or development environment setup
What Are Development Containers?
A development container (dev container) is a running Docker container with a well-defined tool/runtime stack and its prerequisites. The configuration is defined in a devcontainer.json file that tells VS Code (or other supporting tools) how to access or create a development container.
Key Benefits:
- Consistency: Same environment for all developers
- Repeatability: Quickly recreate environments
- Isolation: Separate tools/libraries per project
- Onboarding: New developers get productive faster
- CI/CD Integration: Same environment for local dev and testing
The Specification: Dev containers follow the open Development Containers Specification maintained by the devcontainers community.
Prerequisites

System Resources
- Minimum: 1 GB RAM
- Recommended: 2 GB RAM and 2-core CPU
Installation Steps
Windows/macOS:
- Install Docker Desktop from https://www.docker.com/products/docker-desktop

- Install VS Code from https://code.visualstudio.com/
- Install the Dev Containers extension from the VS Code Extensions marketplace
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.

skill-148 is a skill published in the GitHub repository legendtkl/agentic-skill-router (5 stars, last pushed 3mo ago), licensed MIT. It adds 101 tokens to every session and 4,827 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
