deep-thinklisted

Structured sequential thinking engine for complex reasoning, multi-variable decisions, and strategy under uncertainty. Breaks problems into numbered thought steps with revision and branching support. Replaces the Sequential Thinking MCP server with visible, challengeable reasoning tailored to CEO decision-making. Engage this skill PROACTIVELY -- without waiting for the user to ask -- whenever a problem involves multi-variable decisions, contradictory signals, high-stakes reasoning, strategy under uncertainty, or when you catch yourself making unexamined assumptions. Use when the user says "think through this", "break this down", "reason through", "what are we missing", "think step by step", "structured thinking", "analyze this carefully", "help me think about", "deep think", or any request requiring deliberate multi-step reasoning before action. This is the thinking engine that precedes and sharpens every other skill.

# Deep Think Structured sequential reasoning engine. Breaks complex problems into visible, numbered thought steps -- with revision, branching, and maritime-framed recommendations. Every assumption surfaced. Every path explored. Every recommendation backed by the chain of reasoning that produced it. This skill replaces the Sequential Thinking MCP server. The key improvement: reasoning is visible and challengeable, not hidden inside tool calls. --- ## Variables - `problem` (required) -- The question, decision, or problem to think through - `depth` (optional) -- `quick` (3-5 steps), `standard` (6-10 steps, default), `deep` (10-15+ steps) - `context` (optional) -- Additional context, constraints, or files to reference --- ## Customization (optional, Phase 0) This skill is customization-aware (pilot). Before reasoning, resolve any per-exec overrides: `python "${CLAUDE_PLUGIN_ROOT}"/scripts/resolve_customization.py --skill .claude/skills/deep-think`. Apply any `activation_steps_prepend`, `persistent_facts` (facts to always honour, e.g. a preferred default depth or currency), and output-path overrides from the merged result. On any failure, proceed with the defaults below -- never block. Layout + authoring guide: `config/skill-custom/README.md`. --- ## When to Engage Proactively Activate this skill WITHOUT being asked when you detect any of these conditions: 1. **Multi-variable decisions** -- 3+ competing factors with no obvious weighting. Example: "Should we enter [a ne
