What problem does it solve?

This Skill helps theorem-proving agents quickly locate the right proof pattern, local lemma, or macro strategy when a direct argument is messy, unstable, or too slow to develop from scratch.

Core Features & Use Cases

  • Indexed proof lookup: Search by task shape, assumptions, desired move, tags, or material source ID.
  • Cooked proof playbooks: Use finalized proof entries instead of raw extraction notes, with clear adaptation guidance and failure modes.
  • Public-source traceability: Follow material IDs back to stable source mappings and cited papers when deeper context is needed.
  • Use case: If a proof needs regret decomposition, uncertainty gating, or error-bound localization, this Skill points to the matching reusable move and explains how to apply it.

Quick Start

Ask the proof-usage skill to find the best proof move for your theorem goal and assumptions.

FAQPage Schema
How do I find reusable proof strategies for regret decomposition and self-normalization arguments?

Reusable proof strategies for regret decomposition and self-normalization are found by searching indexed proof playbooks using task shape, assumptions, and desired moves. This delivers finalized proof entries with adaptation guidance instead of raw extraction notes.

What is the best way to locate local lemmas for determinant-based epoch control and error-bound localization?

Locating local lemmas for determinant-based epoch control and error-bound localization requires matching your task shape and assumptions against indexed proof patterns. This returns source-linked proof moves with clear failure modes and adaptation guidance.

Can I trace a proof pattern back to the original cited paper and source mappings?

Proof patterns are fully traceable back to original cited papers using stable material source IDs. This public-source traceability preserves attribution and provides deeper context when you need to verify the underlying theorem proving logic.

Does this proof search approach provide guidance on adapting macro strategies to specific theorem goals?

This proof search approach provides explicit adaptation guidance and failure modes for applying macro strategies to specific theorem goals. You receive cooked proof playbooks that explain how to apply the matching reusable move within your assumptions.

When should I use indexed proof lookup instead of developing a direct argument from scratch?

Use indexed proof lookup when a direct argument is messy, unstable, or too slow to develop from scratch. It quickly points to the matching reusable move and explains how to apply it for complex theorem proving tasks.
