AI workflow cost token auditor
Example session with this skill installed
Audit my current customer support agent workflow. I am seeing high costs on the 'triage' step. The logs and prompt templates are in /docs/support-agent-v2/. Run this manually, no connectors.
- Read your context and instructions
- Compiled the ai workflow cost
Audit complete for customer support agent v2. I identified three primary drivers for the high triage costs, centered on redundant context and model over-provisioning.
AI Workflow Cost Audit: Support Agent Triage
| Waste Pattern | Observation | Recommended Action | Est. Savings |
|---|---|---|---|
| Context Stuffing | System prompt (4k tokens) is sent with every single triage request. | Implement Prompt Caching for the system instructions and few-shot examples. | 40-60% |
| Model Misrouting | Using GPT-4o for binary intent classification (Support vs. Billing). | Route initial classification to GPT-4o-mini or Haiku 3.5. | 80-90% |
| Retry Bloat | 15% of requests retry on JSON parse errors due to weak formatting instructions. | Add a Pydantic-style schema check and improve formatting directives to reduce retries. | 10-15% |
Strategic Roadmap
Immediate: Route Tier 1. Move the initial triage classification to a smaller model. This handles 90% of requests at 1/20th the cost.
2.
Short-term: Enable Caching. Modify the API call to flag the system prompt and static few-shot examples as cacheable headers.
3.
Mid-term: Eval Implementation. Deploy the included pass-fail rubric to ensure GPT-4o-mini classification accuracy matches the current GPT-4o baseline.
Next steps
- Review the
evals_rubric.mdI generated in your workspace to verify classification accuracy. - Update
triage_config.jsonwith the new model routing logic. - Monitor for 'cache_hit' tokens in your provider dashboard over the next 24 hours.

About this skill
Scaling LLM features often leads to runaway API bills and inefficient token usage. This skill audits existing AI workflows to find waste patterns like context stuffing and model misrouting without compromising output quality.
What it does
- Waste detection Flags oversized system prompts, redundant retries, and expensive models used for simple tasks.
- Cost mapping Builds detailed spend breakdowns by workflow step, model, and context window usage.
- Architecture optimization Evaluates routing alternatives such as prompt caching, smaller-model extraction, and batch processing.
- Quality safeguarding Defines eval sets and pass-fail rubrics to ensure cost cuts do not trigger regressions.
- Strategic roadmapping Provides prioritized implementation steps and monitoring plans for long-term spend control.
How it works
- Inventory phase The user provides workflow definitions, prompt templates, and logs via files or text.
- Waste analysis The skill scans for high-cost patterns including low cache reuse and unnecessary agent fan-out.
- Architecture comparison It simulates cost savings for alternative routing and retrieval strategies.
- Recommendation It delivers a prioritized roadmap with a quality-risk matrix for each change.
Frameworks & tools
Works with patterns derived from LiteLLM, promptfoo, and LangGraph. Compatible with environment-specific connectors for GitHub, CRMs, and ticketing systems.
Why this beats prompting it yourself
Writing a simple prompt rarely catches architectural waste like multi-agent redundancy or missing caching layers. This skill applies systematic practitioner-level tradeoffs and enforces a strict quality gate before any cost-saving measure is recommended.
Use cases
- Auditing a high-traffic SaaS chatbot to reduce monthly API overhead.
- Optimizing data extraction pipelines that currently use expensive frontier models for basic parsing.
- Refactoring complex agentic workflows to eliminate redundant context stuffing in loops.
- Justifying a move from frontier models to fine-tuned or smaller-scale routed architectures.
Known limitations
Requires either exported logs or manual workflow descriptions to be effective. It cannot pull live pricing for custom enterprise contracts unless data is provided.
How to use
Skills on Agensi run inside your AI agent. Copy the prompt, paste it into your agent, and it connects to Agensi and installs this skill for you. If a payment is needed, your agent shows it to you first.
