ai-product SKILL.md skillB
ai-product from ghosteken/agent-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ghosteken/agent-harness/ai-product@git:20260721.efafd9cPins git:20260721.efafd9c in mdr.lock. Pin the fingerprint instead.

Every product will be AI-powered. The question is whether you'll.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI Product Development Every product will be AI-powered. The question is whether you'll build it right or ship a demo that falls apart in production. This skill covers LLM integration patterns, RAG architecture, prompt engineering that scales, AI UX that users trust, and cost optimization that doesn't bankrupt you. ## Principles - LLMs are probabilistic, not deterministic | Description: The same input can give different outputs. Design for variance. Add validation layers. Never trust output blindly. Build for the edge cases that will definitely happen. | Examples: Good: Validate LLM output against schema, fallback to human review | Bad: Parse LLM response and use directly in database - Prompt engineering is product engineering | Description: Prompts are code. Version them. Test them. A/B test them. Document them. One word change can flip behavior. Treat them with the same rigor as code. | Examples: Good: Prompts in version control, regression tests, A/B testing | Bad: Prompts inline in code, changed ad-hoc, no testing - RAG over fine-tuning for most use cases | Description: Fine-tuning is expensive, slow, and hard to update. RAG lets you add …

How to install
mdr add ghosteken/agent-harness/ai-product@sha256:16a4aafed03f0907The line at the top of this page pins the label git:20260721.efafd9c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
