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 | $0.00000 | $0.00657 |
| Opus 5.5 | $0.00000 | $0.00263 |
| Sonnet 5.5 | $0.00000 | $0.00131 |
| Haiku 4.5 | $0.00000 | $0.00066 |
Grade D, and why
install-taskmaster scanned grade D with 3 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 1mo 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.

How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Check if Task Master is installed and install it if needed.
This command helps you get Task Master set up globally on your system.
Detection and Installation Process
-
Check Current Installation
# Check if task-master command exists which task-master || echo "Task Master not found" # Check npm global packages npm list -g task-master-ai -
System Requirements Check
# Verify Node.js is installed node --version # Verify npm is installed npm --version # Check Node version (need 16+) -
Install Task Master Globally If not installed, run:
npm install -g task-master-ai -
Verify Installation
# Check version task-master --version # Verify command is available which task-master -
Initial Setup
# Initialize in current directory task-master init -
Configure AI Provider Ensure you have at least one AI provider API key set:
# Check current configuration task-master models --status # If no API keys found, guide setup echo "You'll need at least one API key:" echo "- ANTHROPIC_API_KEY for Claude" echo "- OPENAI_API_KEY for GPT models" echo "- PERPLEXITY_API_KEY for research" echo "" echo "Set them in your shell profile or .env file" -
Quick Test
# Create a test PRD echo "Build a simple hello world API" > test-prd.txt # Try parsing it task-master parse-prd test-prd.txt -n 3
Troubleshooting
If installation fails:
Permission Errors:
# Try with sudo (macOS/Linux)
sudo npm install -g task-master-ai
# Or fix npm permissions
npm config set prefix ~/.npm-global
export PATH=~/.npm-global/bin:$PATH
Network Issues:
# Use different registry
npm install -g task-master-ai --registry https://registry.npmjs.org/
Node Version Issues:
# Install Node 18+ via nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
nvm install 18
nvm use 18
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.
