Tokna — Active Performance # Tokna AI Performance Engineer — Active Performance & Cost Engineering Cost Engineering

Optimize your AI development lifecycle for peak performance and minimal spend. This skill combines real-time turn optimization (latency, throughput, caching) with a final deep-structural audit to ensure your AI code and agent workflows are high-performance, engineering-grade, and cost-efficient.

Core Capabilities

1. Active Turn Optimization (Performance & Efficiency)

Automatically enforces engineering best practices during the development loop:

• Latency & Throughput Guard: Monitors token-per-second and suggests optimizations (like streaming or model-swapping) to maintain high-performance interaction.
• Prompt Caching Enforcer: Automatically applies ephemeral caching to system prompts and history, reducing latency and saving 90% on input costs.
• Selective Fetching: Intercepts data-heavy tools (browser, file-read) to enforce subset loading, preventing "context bloat" that slows down model reasoning.

2. Success Interceptor (The Performance Audit)

Automatically triggers a deep check before code is submitted.

• Stop Hook Performance Gate: When the model finishes a task, Tokna runs 220+ specialized Semgrep rules against the new code.
• Regression Detection: Catches performance and cost "smells" like unbounded loops, inefficient polling, missing TTLs, and uncompressed data transfers.
• Self-Correction Loop: Violations are fed back to the model for an automatic fix turn, ensuring you ship high-performance code by default.

Usage

Manual Scan

scan_repo.py <path> Force a manual audit of the current directory for all cost regression vectors.

Cost Analysis

analyze_cost.py <snippet_or_file> Analyze a specific piece of code or an LLM call configuration for cost risks.

Project Context

Vision: "Performance Engineering for the Agentic Era." Moat: Powered by Nick's experience in Capacity Engineering at Google and Salesforce. Rules are updated daily via the Tokna research pipeline.
