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 | $0.00065 | $0.00678 |
| Opus 5 | $0.00032 | $0.00339 |
| Sonnet 5 | $0.00013 | $0.00136 |
| Haiku 4.5 | $0.00006 | $0.00068 |
Grade B, and why
devcontainer-setup 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

DevContainer Setup Skill
When to Use
- User asks to set up a DevContainer or development environment
- User mentions AI-ready development setup
- Project needs containerized development with multiple language runtimes
Instructions
Step 1: Create directory structure
mkdir -p .devcontainer/snowflake-ai-tools
Step 2: Copy templates
Copy these files from the skill templates folder:
| Source | Destination |
|---|---|
templates/devcontainer.json |
.devcontainer/devcontainer.json |
templates/snowflake-ai-tools/devcontainer-feature.json |
.devcontainer/snowflake-ai-tools/devcontainer-feature.json |
templates/snowflake-ai-tools/install.sh |
.devcontainer/snowflake-ai-tools/install.sh |
If no requirements.txt exists in project root, also copy:
| Source | Destination |
|---|---|
templates/requirements.txt |
requirements.txt |
Step 3: Make scripts executable
chmod +x .devcontainer/snowflake-ai-tools/install.sh
Step 4: Remind user to create host directories
Run this on their host machine before opening the devcontainer:
mkdir -p ~/.m2 ~/.npm ~/.cache/uv ~/.cargo ~/.snowflake ~/.claude ~/.cursor
Step 5: Remind user about config files
These should exist on the host:
~/.snowflake/connections.toml- Snowflake CLI config~/.claude/- Claude Code config
Template Locations
All templates are in this skill's templates/ folder:
What ships with it
6 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.

devcontainer-setup is a skill published in the GitHub repository sfc-gh-dflippo/snowflake-dbt-demo (33 stars, last pushed 25d ago), licensed Apache-2.0. It adds 65 tokens to every session and 678 once invoked, about $0.0003 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 2026-08-30.
