Workflow Optimization

Workflow Optimization Knowledge Base

When to Use This Skill

• Creating any Claude Code artifact
• Optimizing existing artifacts
• Validating artifact quality
• Reviewing workflow configurations

Core Optimization Principles

1. Minimal Signal Principle

Goal: Smallest possible set of high-signal tokens that maximize desired behavior.

Token Budgets:

Test Each Line:

1. Can Claude infer this from code? → Remove
2. Does this change Claude's behavior? → Keep if yes
3. Is this project-specific? → Keep if yes
4. Will this become stale? → Reference external doc instead

2. Attention Budget Optimization

"Lost in the Middle" Effect: Models pay less attention to content in the middle of long contexts.

Placement Strategy:

┌─────────────────────────┐
│ CRITICAL RULES (first)  │ ← Maximum attention
├─────────────────────────┤
│ Details & examples      │ ← Moderate attention
├─────────────────────────┤
│ Edge cases              │ ← Lower attention
├─────────────────────────┤
│ CRITICAL RULES (repeat) │ ← Attention rises at end
└─────────────────────────┘

Bookend Pattern: Repeat critical instructions at both START and END of artifact.

3. Specificity Over Generality

❌ Vague (Low Value):

Follow best practices for error handling.

✅ Specific (High Value):

Error handling:
- Catch specific exceptions (never bare `except:`)
- Log with context: logger.error("Failed to X", {userId, error})
- Re-raise after logging unless recoverable
- Pattern: src/core/errors.py

4. Action-Oriented Framing

❌ Descriptive (Passive):

Tests should be written before merging.

✅ Imperative (Active):

Run `npm test` and verify all pass before committing.

Optimization Patterns by Artifact Type

Commands

Frontmatter Optimization:

---
allowed-tools: [Minimal set needed - principle of least privilege]
argument-hint: [Clear format, e.g., "[file] [--flag]"]
description: [<80 chars, verb phrase: "Generate X for Y"]
---

Body Structure:

# [Purpose - 3-5 words]

$ARGUMENTS contains: [exact format expected]

## Process
1. [Step] - [brief instruction]
2. [Step] - [brief instruction]

## Output
[Exact format specification]

## Constraints
- [Non-negotiable rule]
- [Non-negotiable rule]

Tool Scoping Patterns:

Read-only analysis: Read, Glob, Grep
Code generation: Read, Write, Glob, Grep
Code modification: Read, Write, Edit, MultiEdit, Glob, Grep
Limited shell: Bash(npm:*), Bash(git:*)
Full shell: Bash (use sparingly)

Skills

Description Formula:

[What] + [Domain/Technology] + "Use when" + [Triggers]

Example:

PostgreSQL query optimization patterns. Use when writing complex queries, 
debugging slow queries, or designing schemas for PostgreSQL databases.

Structure:

# [Skill Name]

## When to Use
- [Explicit trigger 1]
- [Explicit trigger 2]

## Patterns
### [Pattern Name]
[Example with explanation]

### Anti-Pattern: [Name]
[Bad example]
Why: [Reasoning]

Agents

Role Definition:

## Identity
You are a [specific title] with [years] experience in [domain].
Your expertise: [bullet list of 3-4 specific skills]

## Mission
[Single sentence: what you do and why]

Tool Scoping by Agent Type:

CLAUDE.md

Priority Order:

1. Commands (developers use these daily)
2. Warnings (prevent costly mistakes)
3. Architecture (context for decisions)
4. Conventions (code consistency)

Compression Techniques:

# Before (verbose)
## Database
We use PostgreSQL as our primary database. All database operations
should go through the ORM layer using Sequelize. Direct SQL queries
should be avoided except in special circumstances.

# After (compressed)
## Database
PostgreSQL via Sequelize ORM. Direct SQL only in `src/db/raw/`.

Hooks

Performance Rules:

• Hooks run on EVERY matching operation
• Keep commands fast (<5 seconds)
• Use || true for non-critical hooks
• Avoid network calls in hooks

Common Patterns:

// Auto-format (most common)
{"type": "command", "command": "prettier --write $CLAUDE_FILE_PATHS || true"}

// Lint check
{"type": "command", "command": "eslint $CLAUDE_FILE_PATHS --fix || true"}

// Type check (TypeScript)
{"type": "command", "command": "tsc --noEmit 2>/dev/null || true"}

Anti-Patterns to Avoid

1. Prompt Stuffing

❌ Including everything "just in case"
✅ Include only what changes behavior

2. Aspiration Documentation

❌ "We're moving toward microservices..."
✅ "Monolith with service layer. Events in src/events/."

3. Generic Boilerplate

❌ "Follow TypeScript best practices"
✅ "strict: true, prefer type over interface, Zod for runtime"

4. Implicit Context

❌ "Use the standard pattern"
✅ "Use pattern from src/services/base.ts"

5. Conflicting Instructions

❌ "Prioritize speed. Prioritize readability. Prioritize security."
✅ "Priority: (1) correctness, (2) security, (3) readability, (4) speed"

6. Over-Constraint

❌ "Never use any external libraries"
✅ "Prefer stdlib; new deps need justification in PR"

Validation Checklists

Command Validation

• Description <80 chars

Workflow Architecture Patterns

Linear Pipeline

Input → Step1 → Step2 → Step3 → Output

Best for: Sequential transformations

Parallel Fan-Out

        ┌→ Agent1 ─┐
Input ──┼→ Agent2 ──┼→ Aggregator → Output
        └→ Agent3 ─┘

Best for: Independent analyses

Conditional Branching

Input → Classifier ─┬→ PathA → Output
                    └→ PathB → Output

Best for: Type-dependent processing

Iterative Refinement

Input → Generate → Validate ─┬→ Output (if valid)
                             └→ Refine → Validate (loop)

Best for: Quality-sensitive outputs

Metrics for Success

Optimization Success Indicators:

• Token usage reduced by 30%+
• First-attempt success rate >80%
• No conflicting instructions
• All artifacts pass validation
• Documentation enables updates
