# Agent Task Cost & Time Estimator Estimate the likely token consumption, API cost, and wall-clock time of an agent task **before** it is executed. Provide clear, conservative ranges rather than single numbers, and explain the assumptions. ## When to invoke - The user asks for a cost/token/time estimate before running an agent task. - The user wants to know "how expensive will this be?", "how many tokens will this use?", or "how long will this take?". - The user is deciding whether to proceed with a complex agent workflow. ## Inputs to collect 1. **Task description** — what the agent is asked to do. 2. **Target model** — e.g. `claude-sonnet-4`, `gpt-4o`, `claude-3-5-sonnet`, `gemini-2.5-pro`. 3. **Context size** — approximate tokens already in the conversation or repo context: - System prompt size - Relevant files / codebase tokens - Existing conversation history 4. **Complexity class** — choose one: - `simple` — single file edit, one-step answer, short explanation. - `medium` — multi-file read/modify, 2���4 tool calls, moderate reasoning. - `complex` — large refactor, multi-step debugging, agent loop with many tool calls. 5. **Expected output** — approximate length of the final response or code change. 6. **Tooling environment** — e.g. local CLI, cloud API, agent framework with built-in retries, parallel sub-agents. 7. **Currency** — default to USD unless the user asks otherwise. ## Estimation method ### 1.
