/deep-think — Maximum Cognitive Effort Protocol

Goal: Activate the highest level of cognitive architecture for complex, multi-step, or ambiguous tasks where quality matters more than speed. Time: 5-15 minutes depending on complexity tier. When to use: Architecture decisions, multi-system changes, irreversible actions, anything where being wrong is expensive.

This is NOT /reason. /reason = "follow the reasoning engine checklist" (fast, lightweight). /deep-think = "maximum effort with structured thinking, research, gap analysis, multi-perspective debate, and adversarial review" (slow, thorough).

Complexity Gate (decide first)

Before starting, classify the task:

Tier	When	Phases Used
SIMPLE	Quick but thorough — single-domain analysis, clear question	Phases 1 + 5 only
MEDIUM	Research + analysis — multi-source synthesis, comparison	Phases 1-5
COMPLEX	Full adversarial — architecture decisions, multi-system changes, irreversible actions	All 8 phases

Phase 1: ORIENT (Memory + Context)

Load ALL available context before forming any opinion.

1. Read project memory if available (e.g., MEMORY.md, SESSION.md, or status logs)
2. Read known pitfalls and gotchas for the target domain (e.g., knowledge/gotchas.md if present)
3. Read the most relevant local knowledge, READMEs, or chunk files
4. Query any active workspace memory system (e.g., Honcho or agentmemory) when recent session continuity is needed
5. Check conversation logs or history for prior attempts or context on this topic
6. Identify which projects, modules, or systems are involved

If any tool fails: Note "degraded mode" and continue with available sources. Do NOT stall.

---

Phase 2: QUESTION (Challenge the Request)

Before solving, challenge the problem statement itself.

1. Use a sequential thinking or reasoning tool (such as sequential-thinking MCP, if available) to decompose the problem into component parts
2. Ask explicitly:
   • "Is this the right question? Is there a better framing?"
   • "What assumptions are embedded in this request?"
   • "What would go wrong if I do the obvious thing?"
   • "Has this been attempted before? What happened?"
3. If the framing reveals a deeper issue, address THAT instead

---

Phase 3: RESEARCH (Evidence Collection)

Gather evidence from multiple sources. Do NOT rely on training data alone.

1. Run web searches for current best practices, official documentation, and known issues
2. Use available documentation search tools (such as Context7 MCP, if available) for any referenced libraries, frameworks, or APIs
3. Check repository skills and custom workspace procedures (e.g., under .agent/skills/ or similar locations)
4. Load domain-specific context or chunk files using workspace routing maps (e.g., WORKSPACE-AUTOMAP.md or equivalent)
5. Review workspace-specific conventions and code style files (e.g., knowledge/conventions.md or local READMEs) for established patterns

Rule: Every factual claim must trace to a retrieved source, not memory.

---

Phase 4: AUDIT (Gap Analysis)

For architecture and system tasks. Skip for pure analysis questions.

1. What exists? List all relevant files, tools, configs currently in place
2. What SHOULD exist? Based on research and requirements, what's the ideal state?
3. What's the delta? Enumerate every gap between current and ideal
4. What's stale? Cross-reference sources for contradictions and outdated information
5. What's broken? Check tool health, file integrity, reference validity

---

Phase 5: SYNTHESIZE (Multi-Perspective Analysis)

Evaluate the problem from multiple expert perspectives.

1. Council of Experts — consider the problem as:
   • A Lead Developer: Is this technically sound? What are the edge cases?
   • A Business/Product Strategist: Does this serve the core project objectives and business outcomes?
   • A UX/Ops Pro: Is this maintainable? Will it create friction?
2. Reconcile conflicts between perspectives and sources
3. Produce a structured recommendation with:
   • The recommended approach
   • The key tradeoff
   • The risk if wrong
   • The success criteria

---

Phase 6: PLAN (Surgical Execution Design)

Break the recommendation into executable steps.

1. Decompose into the smallest possible steps — each independently verifiable
2. Run the 5-step Pre-Action Verification Protocol on EACH step:
   • Are assumptions stated?
   • Am I targeting the correct file/resource?
   • Is scope minimal?
   • Is action reversible?
   • What are the success criteria?
3. Define measurable success criteria for the overall task
4. Sequence steps so failures are caught early (dependencies first)

---

Phase 7: EXECUTE + VERIFY (Work → Check → Correct)

Execute the plan one step at a time.

1. One step at a time. Verify output after each step before proceeding.
2. Work → Verify → Self-Correct loop. Do not assume success.
3. Anti-Bulk Enforcement: Use the most surgical edit mechanism available. Never rewrite files unless creating from scratch.
4. 80% Confidence Threshold: If confidence drops below 80% on a high-stakes decision, STOP and ask the user/product owner for input.
5. Follow Karpathy Doctrine: surgical, minimal, explicit.

---

Phase 8: CHALLENGE (Adversarial Self-Review)

After producing the result, attack it.

1. Re-read the original request word by word. Did you actually answer THE question?
2. What did you miss? What would a senior expert critique about this output?
3. Would you stake your reputation on this? If not, what needs to change?
4. Edge cases: What happens under unusual conditions? Empty inputs? Scale? Concurrent use?
5. Save key learnings to the appropriate memory layer:
   • Debugging insights → update known gotchas (e.g., knowledge/gotchas.md)
   • New patterns → update conventions/standards (e.g., knowledge/conventions.md)
   • Decisions made → update decisions log (e.g., knowledge/decisions.md)
   • Recent continuity worth reusing soon → write a milestone/handoff breadcrumb to the workspace memory system (e.g., Honcho or agentmemory)

What This Workflow Does NOT Do

• It does NOT replace /reason for quick analysis — use /reason for fast reasoning engine activation.
• It does NOT save session state — that's /wrap.
• It does NOT consolidate memory — that's /dream.
