deepthinking-mcp

Structured reasoning for Claude Code, in one plugin: an MCP server (34 modes, 13 tools, meta-reasoning, taxonomy classification) plus the /think and /think-render slash commands, 14 reasoning skills covering 46 modes, and the visual-exporter subagent. Absorbed deepthinking-plugin on 2026-08-03.

This plugin runs code on your machine — it starts local MCP servers. The exact commands are listed below; read them before installing.

What it installs

Skills (14)

  • think-academic

    Academic research reasoning methods — Synthesis (integrating sources, literature review, multi-source coherence), Argumentation (Toulmin model with claim/warrant/backing/qualifier/rebuttal), Critique (peer-review style evaluation, strengths/weaknesses, Socratic questions), and Analysis (systematic d

  • think-advanced

    Advanced runtime reasoning methods — Recursive (self-referential decomposition, base case + recursive case, halting), Modal (possibility, necessity, alethic/epistemic/deontic modalities, possible-worlds semantics), and Stochastic (probability distributions, Monte Carlo sampling, random processes). U

  • think-analytical

    Advanced analytical reasoning methods — Analogical (cross-domain mapping, structural similarity), FirstPrinciples (fundamental decomposition, axiom derivation), MetaReasoning (strategic oversight of your own reasoning process), and Cryptanalytic (code-breaking, pattern extraction, weighted Decibans

  • think-causal

    Causal reasoning methods — Causal analysis (cause-effect mechanisms, causal graphs, confounders) and Counterfactual reasoning (what-if scenarios, alternative histories, intervention analysis). Use when the user invokes `/think causal` or `/think counterfactual`, or asks about cause-and-effect relati

  • think-core

    Core reasoning triad — Inductive, Deductive, and Abductive. Use when the user invokes `/think inductive`, `/think deductive`, or `/think abductive`, or asks to generalize from examples, derive conclusions from rules, or find the best explanation for observations.

  • think-engineering

    Engineering and algorithmic reasoning methods — Engineering (design trade-offs, constraint-driven decisions, reliability/performance/cost trade-offs) and Algorithmic (CLRS algorithm categories, complexity analysis, data structure selection, problem-to-algorithm matching). Use when the user invokes `

  • think-frameworks

    Analytical framework reasoning methods — 5W1H, SWOT, 5 Whys, Fishbone, PESTLE, Force Field, Decision Matrix, Pareto, Stakeholder, Cost-Benefit, Risk Assessment, Gap Analysis. Use when the user invokes `/think <framework>` or asks for structured problem definition, strategic analysis, root-cause, pri

  • think-mathematics

    Mathematical, physical, and computational reasoning methods — Mathematics (proofs, algebra, calculus), Physics (tensors, conservation laws, symmetries), and Computability (Turing machines, decidability, complexity classes). Use when the user invokes `/think mathematics`, `/think physics`, or `/think

  • think-probabilistic

    Probabilistic reasoning methods — Bayesian inference and Evidential reasoning. Use when the user invokes `/think bayesian` or `/think evidential`, or asks about updating beliefs with evidence, computing posterior probabilities, weighing multi-source evidence, or probabilistic inference under uncerta

  • think-scientific

    Scientific and structural reasoning methods — Scientific Method (hypothesis formation, experiment design, falsifiability), Systems Thinking (feedback loops, 8 systems archetypes, leverage points), and Formal Logic (propositional/predicate logic, formal proofs, soundness). Use when the user invokes `

  • think-standard

    Standard sequential, information-theoretic, and hybrid reasoning methods. Use when the user invokes `/think sequential`, `/think shannon`, or `/think hybrid`, or asks to break down a complex task into ordered steps, decompose uncertainty systematically, or compose multiple reasoning modes for a cros

  • think-strategic

    Strategic reasoning methods — Game Theory (Nash equilibria, payoff matrices, cooperative/non-cooperative games), Optimization (objective functions, constraints, feasible regions), and Constraint Satisfaction (CSP formulation, arc consistency, backtracking). Use when the user invokes `/think gametheo

  • think-temporal

    Time-aware reasoning methods — Temporal (event sequences, time intervals, causation across time) and Historical (source evaluation, pattern detection across historical episodes, precedent analysis). Use when the user invokes `/think temporal` or `/think historical`, or asks about event ordering, tim

  • think

    Route a reasoning task to the appropriate thinking mode. Use when the user invokes `/think <mode?> "<problem>"` or asks for structured reasoning, critical analysis, Bayesian inference, causal analysis, inductive/deductive reasoning, hypothesis formation, analytical frameworks (5W1H, SWOT, 5 Whys, Fi

Slash commands (2)

  • /deepthinking-mcp:think-render

    Render the most recent structured thought output (from /think) as a diagram or document. Usage: /think-render [format] where format is mermaid, dot, ascii, json, markdown, graphml, html, tikz, uml, modelica, dashboard, latex-math, csv, svg, or png (defaults to mermaid).

  • /deepthinking-mcp:think

    Apply a structured reasoning method to a problem. Usage: /think [mode] \"<problem>\" where mode is any of the 46 available modes or omitted for auto-recommend.

Subagents (1)

  • visual-exporter

    Convert a structured deepthinking thought into diagram source code. Use when the user asks to visualize, render, draw, or diagram the output of a recent /think invocation. Supports 13 formats: mermaid, dot, ascii, json, markdown, graphml, html, tikz, uml, modelica, latex-math, csv, and dashboard (in
