# Work Avoidance Techniques

## When to Use This Skill

Each technique answers a specific question:

| Technique | Question | Best For |
| ----------- | ---------- | ---------- |
| [Content Hashing](content-hashing.md) | "Is the content different?" | File comparisons, config sync |
| [Volatile Field Exclusion](volatile-field-exclusion.md) | "Did anything meaningful change?" | Version bumps, timestamps |
| [Existence Checks](existence-checks.md) | "Does it already exist?" | Resource creation (PRs, branches) |
| [Cache-Based Skip](cache-based-skip.md) | "Is the output already built?" | Build artifacts, dependencies |
| [Queue Cleanup](queue-cleanup.md) | "Should queued work execute?" | Mutex-locked workflows |

---


## Implementation

See the full implementation guide in the [source documentation](https://adaptive-enforcement-lab.com/patterns/efficiency/).

### Overview

Each technique answers a specific question:

| Technique | Question | Best For |
| ----------- | ---------- | ---------- |
| [Content Hashing](content-hashing.md) | "Is the content different?" | File comparisons, config sync |
| [Volatile Field Exclusion](volatile-field-exclusion.md) | "Did anything meaningful change?" | Version bumps, timestamps |
| [Existence Checks](existence-checks.md) | "Does it already exist?" | Resource creation (PRs, branches) |
| [Cache-Based Skip](cache-based-skip.md) | "Is the output already built?" | Build artifacts, dependencies |
| [Queue Cleanup](queue-cleanup.md) | "Should queued work execute?" | Mutex-locked workflows |

---


### Combining Techniques

Techniques can be layered for maximum efficiency:

```mermaid
flowchart TD
    subgraph layer1[Layer 1: Existence]
        Exists{Resource exists?}
    end

    subgraph layer2[Layer 2: Content]
        Hash{Content hash matches?}
    end

    subgraph layer3[Layer 3: Semantic]
        Volatile{Only volatile fields changed?}
    end

    subgraph action[Action]
        Skip[Skip]
        Execute[Execute]
    end

    Exists -->|Yes| Hash
    Exists -->|No| Execute
    Hash -->|Yes| Skip
    Hash -->|No| Volatile
    Volatile -->|Yes| Skip
    Volatile -->|No| Execute

| File distribution with version bumps | [Volatile Field Exclusion](volatile-field-exclusion.md) |
| OCI image rebuilds | [Content Hashing](content-hashing.md) |
| PR/branch creation | [Existence Checks](existence-checks.md) |
| Dependency installation | [Cache-Based Skip](cache-based-skip.md) |
| API state synchronization | [Content Hashing](content-hashing.md) |
| Generated file deployment | [Volatile Field Exclusion](volatile-field-exclusion.md) |
| Idempotent workflows with mutex locks | [Queue Cleanup](queue-cleanup.md) |
