SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a lean, cost-aware dispatcher to orchestrate tiered model calls, minimizing runtime cost while preserving gate quality by using Haiku/Sonnet for planning and execution, with a post-gate fix loop and manifests for cost accounting.

Core Features & Use Cases

  • Two-file contract+sprints output (contract.md and sprints.jsonl)
  • Deterministic per-sprint execution using Haiku
  • Bare, cost-aware model calls with manifest-based reporting
  • Gate-based verification and surgical-fix loop
  • Use Case: Architects can plan a multi-sprint build and delegate execution to a cheaper model while preserving contract fidelity.

Quick Start

Place a spec.md in the skill directory, then run python3 dispatch.py to generate contract.md and sprints.jsonl and follow the gate results.

FAQPage Schema
How do I reduce LLM API costs for multi-sprint software builds?

Reduce LLM API costs for multi-sprint builds by using a tiered dispatch loop that writes a planning contract and delegates per-sprint execution to cheaper models like Haiku. This separates planning from execution to minimize runtime cost while maintaining gate quality.

What is tiered-build dispatch for software development?

Tiered-build dispatch is a cost-aware orchestration process that generates a contract and per-sprint briefs, then executes them using tiered LLM models. It applies to multi-sprint builds where planning, cost control, and verification are required.

How do I automate sprint planning and execution with Haiku and Sonnet?

Automate sprint planning and execution with Haiku and Sonnet by running a dispatch script that generates a contract and sprints file. The dispatcher uses Haiku for deterministic per-sprint execution and applies a surgical-fix loop after gate verification.

Best way to orchestrate multi-sprint builds while preserving contract fidelity?

The best way to orchestrate multi-sprint builds while preserving contract fidelity is a lean dispatch loop that writes a contract and per-sprint briefs, then executes them deterministically with cheaper models. A surgical-fix loop handles post-gate verification.

How do I track and log API costs for tiered LLM model calls?

Track and log API costs for tiered LLM model calls using manifest-based reporting generated during the dispatch loop. The dispatcher produces manifest logs that provide cost accounting for the bare, cost-aware model calls executed across sprints.

Does tiered-build dispatch work without external dependencies?

Yes, tiered-build dispatch works without external dependencies. You simply place a spec.md file in the skill directory and run the dispatch script to generate the contract and sprints payloads without requiring additional components.
