Managing Prompts

Comprehensive prompt engineering for Claude 4.5: creation, analysis, optimization, guardrails, context management.

When to Use

  • User requests creating/analyzing/optimizing prompts
  • User asks if current logic should be extracted to prompt
  • User mentions: hallucinations, consistency issues, context optimization, prompt caching, chain-of-thought, XML tags
  • Context usage high and extraction would help
  • Outdated prompt techniques need Claude 4.5 updates

Core Workflows

Workflow 1: Analyzing Existing Prompts

Quick process:

  1. Read prompt file/content
  2. Load quick-reference.md for validation checklist
  3. Apply evaluation: structure, techniques, guardrails, context efficiency, Claude 4.5 optimization
  4. Categorize issues: critical | major | minor
  5. Generate recommendations with priority
  6. Output using output-formats.md#analysis-report template

Detailed evaluation: Load analysis-patterns.md

Common issues reference: quick-reference.md#common-issues

Workflow 2: Creating New Prompts

Quick process:

  1. Gather requirements: objective, success criteria, inputs/outputs, complexity, risk factors
  2. Select architecture: Load architecture-patterns.md, choose: simple_task | complex_reasoning | agent_workflow | multi_window
  3. Apply techniques: Load technique-reference.md for indexed lookup by need
  4. Add guardrails: Based on risk level, load guardrails-implementation.md for patterns
  5. Optimize context: Load context-optimization.md if >10K tokens
  6. Validate: Use quick-reference.md#quick-validation-checklist

Technique order:

  1. Clear instructions (explicit, contextual motivation, success criteria, output format)
  2. Examples (3-5 for complex tasks)
  3. Chain-of-thought (for reasoning tasks)
  4. XML tags (for structure)
  5. Role assignment, prefilling, template variables

Architecture selection:

  • Simple task: Clear objective, straightforward
  • Complex reasoning: Multi-step analysis, judgment
  • Agent workflow: Tool access, iterative, autonomous
  • Multi-window: >100K tokens, extended work

Guardrails by risk:

  • Low: Basic uncertainty permission
  • Medium: Examples + format spec
  • High: Quote-grounding + citations
  • Critical: Full stack (quotes, citations, knowledge restriction, CoT)

Context optimization:

  • Cache static content ≥1024 tokens
  • Place 20K+ docs at beginning
  • Remove Claude's existing knowledge
  • Quote-grounding for large docs
  • Split if >3 distinct subtasks

Workflow 3: Optimizing Existing Prompts

Quick process:

  1. Identify goal: reduce_tokens | improve_quality | increase_consistency | reduce_hallucinations | enable_caching | split_prompt
  2. Load optimization-strategies.md for before/after examples
  3. Apply transformation
  4. Measure improvement
  5. Document using output-formats.md#optimization-report

Quick optimization strategies:

  • Context reduction: Remove redundancy, cache static, quote-grounding, split if >3 subtasks
  • Quality: Add examples, CoT, explicit instructions, contextual motivation
  • Consistency: Format spec, prefilling, 3-5 examples
  • Hallucinations: Uncertainty permission, quote-grounding, citations
  • Caching: Identify ≥1024 static tokens, restructure, add cache_control

Decision aids: quick-reference.md#fast-decision-trees

Workflow 4: Updating Outdated Prompts

Quick process:

  1. Load migration-guide.md for Claude 3→4.5 patterns
  2. Identify outdated: insufficient explicitness, missing motivation, suggestion framing, no summary requests
  3. Apply updates preserving core logic
  4. Test and document

Common migrations:

  • Vague → Explicit instructions with specifics
  • No motivation → Add contextual reasoning
  • Suggestion framing → Action framing ("Improve this" not "Can you improve?")
  • No summaries → Explicit requests (4.5 less verbose by default)
  • No quality modifiers → Add "Give it your all" for creative tasks

Workflow 5: Deciding Logic Extraction

Quick process:

  1. Load extraction-decision-guide.md#decision-tree
  2. Evaluate criteria (6 for prompt, 6 for script)
  3. Score: 3+ = extract, <3 = keep inline
  4. Output using output-formats.md#extraction-decision template

Prompt extraction criteria (3+ to extract):

  • Reused across 3+ contexts
  • Needs prompt techniques (examples, CoT, XML)
  • Benefits from guardrails
  • Context optimization beneficial
  • Standardization needed
  • Complex (>200 tokens instructions)

Script extraction criteria (3+ to extract):

  • Deterministic/algorithmic
  • Computation-heavy
  • Unit testable
  • Reused across prompts
  • No reasoning required
  • Format conversion/validation

Keep inline: One-time, context-specific, simple, requires real-time interaction

Fast Reference System

For validation: quick-reference.md (quick checklist, common issues, decision trees, severity guide)

For technique lookup: technique-reference.md (indexed by use case, lookup table, application patterns, combinations)

For output templates: output-formats.md (analysis, optimization, extraction, creation, migration reports)

For detailed patterns:

  • extended-thinking-implementation.md (internal reasoning, budget management, batch processing, multi-round strategies)
  • prompt-chaining-architecture.md (sequential/parallel workflows, handoff patterns, orchestration, self-correction loops)
  • consistency-techniques.md (prefilling, Structured Outputs, format enforcement, advanced patterns)
  • claude-4-5-optimization.md (4.5-specific guidance: explicit instructions, context awareness, multi-context workflows, tool usage)
  • architecture-patterns.md (5 pattern types: simple task, complex reasoning, agent, multi-window, multi-context workflows)
  • guardrails-implementation.md (hallucination, consistency, security, character patterns, jailbreak prevention, prompt leak reduction)
  • context-optimization.md (token management, caching with model-specific minimums, document org, splitting, cache invalidation patterns)
  • optimization-strategies.md (11 before/after examples)
  • migration-guide.md (Claude 3→4.5 patterns, 10 migration examples)
  • extraction-decision-guide.md (decision trees, criteria, examples)
  • analysis-patterns.md (common issues, quality assessment, evaluation examples)

Claude 4.5 Critical Behaviors

Strengths: Long-horizon reasoning, context awareness, parallel execution, subagent delegation

Requirements: More explicit than Claude 3, contextual motivation, high-quality examples, action framing, explicit summary requests, quality modifiers

Optimization: Parallel tool guidance, clear success criteria, investigation before answering, aesthetic direction (UI), algorithm approach (code)

Quick Troubleshooting

Load quick-reference.md for detailed troubleshooting with fixes.

Common symptoms → Quick fixes:

  • Inconsistent outputs → Format spec + 3-5 examples
  • Hallucinations → Quote-grounding + uncertainty permission
  • High tokens → Cache static content, remove redundancy
  • Too concise (4.5) → Explicit detail requests
  • Suggests not implements (4.5) → Action framing
  • Stops early (4.5) → Reference token budget available

Tool Usage Pattern

Standard workflow:

  1. Identify which workflow (1-5)
  2. Load quick-reference.md for checklist/decisions
  3. Load technique-reference.md if need technique lookup
  4. Load detailed supporting file only when needed
  5. Use output-formats.md template for deliverable

Example - Analysis:

  1. Read prompt
  2. quick-reference.md → validation checklist
  3. technique-reference.md → identify techniques used
  4. analysis-patterns.md → detailed framework (if complex)
  5. output-formats.md#analysis-report → generate output

Example - Creation:

  1. Gather requirements
  2. technique-reference.md → select techniques by need
  3. architecture-patterns.md → get template for pattern type
  4. quick-reference.md → validation before finalizing
  5. output-formats.md#creation-summary → document (optional)

Example - Optimization:

  1. Identify goal
  2. quick-reference.md#fast-decision-trees → decide strategy
  3. optimization-strategies.md → get before/after pattern
  4. Apply and test
  5. output-formats.md#optimization-report → document

Validation Before Deployment

Load quick-reference.md#quick-validation-checklist

Essential checks:

  • [ ] Objective clear, success criteria defined
  • [ ] Instructions explicit (action framing for 4.5)
  • [ ] Output format specified
  • [ ] Examples if complex (3-5, diverse, identical structure)
  • [ ] CoT if reasoning required
  • [ ] XML if multiple components
  • [ ] Guardrails match risk level
  • [ ] Context optimized (caching, placement, splitting)
  • [ ] Claude 4.5 specificity (explicit, motivation, quality modifiers)

Golden test: "Would colleague understand with minimal context?"
