What does the Devika skill do?

Cut LLM cost and latency: routing, caching, prompt slimming and batching, with quality held on every change. Load it once into Claude Projects and you get a configured LLM Cost & Latency Optimizer without re-explaining context at the start of every session. Build and evaluate against a held-out test set in a development or staging environment, add guardrails, cost and rate limits, and human review, and roll out behind evals and monitoring before serving agents or LLM features in production.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Devika skill?

Without a skill file your AI starts every session as a general assistant. With Devika loaded it applies LLM Cost & Latency Optimizer methodology from the first message, with consistent quality every time. Build and evaluate against a held-out test set in a development or staging environment, add guardrails, cost and rate limits, and human review, and roll out behind evals and monitoring before serving agents or LLM features in production.

Token accounting and a cost model that finds the big line items
Model routing/cascades and prompt slimming
Exact, prefix and semantic caching with thresholds
A quality gate on every cost cut, with before/after numbers

Teams with a big LLM bill or slow endpoints who want cost and latency down without quality loss.A senior LLM engineer bills $130+/hr, this is one file, yours forever.

// what's inside

Drop Devika into Claude and get a senior cost and latency optimizer who cuts spend and tail latency while measuring quality on every change.

Devika cuts the cost and latency of LLM features without wrecking quality: token accounting and cost modeling, model routing and cascades (cheap model first, escalate on low confidence), prompt slimming (shorter prompts, fewer and better few-shots, output-length control, structured output), caching (exact, prefix and semantic with thresholds), batching, retrieval trimming, streaming for perceived latency, and quantization tradeoffs, always with a quality gate so you never trade cost for silent quality loss. Tools like LiteLLM, Helicone, Langfuse and tiktoken, without lock-in. Measure quality on a held-out set for every cost cut.

# Devika - LLM Cost & Latency Optimizer

You are Devika, a senior LLM Cost & Latency Optimizer. You measure quality on every cost cut.

## How you work
1. Account for tokens and cost; find the big line items
2. Route/cascade, slim prompts, cap output
3. Cache (exact, prefix, semantic); batch where you can
4. Hold a quality gate; report cost, latency and quality before/after

Never trade cost for silent quality loss. Measure quality on a held-out set for every change before production.

Excerpt from the actual file you'll download.

// try it

prompt

$Our classification endpoint costs $9k/month and is slow. Cut cost and latency without losing accuracy.

Devika returns a cost-breakdown table, a routing + caching + prompt-slimming plan, code for the cascade router, cost calc and semantic cache, and a before/after table (cost/req and p95 down, accuracy held within tolerance).
