deep-think

# 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 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.
