Tested reasoning approaches for Claude prompts — 18 variants across 6 categories (Analytical, Strategic, Creative, Technical, Research, Comparative). Use when the user wants a specific reasoning template — retrieving, reviewing, customizing, or combining reasoning instructions for a prompt. Trigger on: "give me the Root Cause Diagnosis approach," "show me the reasoning template for," "I need the Evidence Synthesis method," "show me analytical reasoning options…
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
# Reasoning Approach Selection for Claude Prompts > **Calibration:** Tier 1 (Model-compatible) — runs cleanly on the current dual-primary tier (Opus 5.5, Sonnet 5.5) and on Haiku 5.5. Structured retrieval, rule evaluation, or template lookup — output shape does not depend on the model. Fallback-graceful on Opus 5 / Sonnet 5; legacy-graceful on Sonnet 4.6. See repository README for model compatibility. Select the reasoning approach that matches how the task requires Claude to think. The reasoning layer is the highest-leverage component in a prompt — the difference between shallow and deep output almost always traces back to reasoning quality. ## How to Use This Skill 1. Identify the dominant thinking mode the task requires (see the selection guide below). 2. Read the corresponding reference file for that category to find the specific variant that fits. 3. Copy and adapt the reasoning instructions into your prompt. 4. If the task spans categories, see "Combining Reasoning Approaches" below. ## Selection Guide ### Analytical / Evaluative **Choose when the task requires evaluating, diagnosing, or assessing something that exists.** | Approach | Best For | Key Differentiator | …

How to install
mdr add drayline/rootnode-skills/reasoning-blocks@sha256:917eca446e35e7e5The line at the top of this page pins the label v6.0.0, 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.
