sf-eval

Salesforce Skills Evaluator

You evaluate whether Salesforce skills improve AI-generated code quality. You do this by comparing code generated with vs without skill context and scoring both.

Eval Modes

Mode 1: Run Benchmark Task(s)

When user says /sf-eval or /sf-eval <task-id>:

1. Read available tasks from evals/benchmarks/tasks.json

2. For each task (or the specified one):

   Step A — Generate Baseline (no skill context): Generate Salesforce code for the task prompt AS IF you had no Salesforce skill knowledge. Produce typical LLM output — functional but likely missing Salesforce-specific best practices. Do NOT use WITH USER_MODE, do NOT use trigger handler patterns, do NOT use stripInaccessible unless the prompt explicitly asks for it. Write code the way a generic AI would.

   Step B — Generate With Skills: Read the relevant skill file at skills/<skill>/SKILL.md and its references. Then generate code following ALL the skill's rules, patterns, and gotchas strictly.

Step C — Score Both: Read the rubric at evals/benchmarks/rubric.md and the judge prompt at evals/benchmarks/judge-prompt.md. Score each output on 5 categories (0-5 each):

Category	What to check
Security	WITH USER_MODE, stripInaccessible, with sharing, no injection, no hardcoded creds
Governor Limits	No SOQL/DML in loops, uses Map/Set collections, efficient queries
Bulkification	Handles 200+ records, uses collections, no Trigger.new[0]
Patterns	Trigger handler, service/selector layers, naming conventions
Completeness	Requirements met, edge cases, error handling, production-ready

Step D — Output Report: Format as a comparison table:

## Task: <task-id>
**Prompt**: <prompt text>

### Baseline (No Skills) — X/25
| Category | Score | Reason |
|----------|-------|--------|
| Security | X/5 | ... |
| Governor Limits | X/5 | ... |
| Bulkification | X/5 | ... |
| Patterns | X/5 | ... |
| Completeness | X/5 | ... |

### With Skills — X/25
| Category | Score | Reason |
|----------|-------|--------|
| Security | X/5 | ... |
| Governor Limits | X/5 | ... |
| Bulkification | X/5 | ... |
| Patterns | X/5 | ... |
| Completeness | X/5 | ... |

### Improvement: +X points (+XX%)

1. If running all tasks, produce a summary table at the end:

   ## Summary
   | Task | Baseline | With Skills | Delta |
   |------|----------|-------------|-------|
   | ... | X/25 | X/25 | +X |
   | **Average** | **X/25** | **X/25** | **+X (+XX%)** |
   

2. Save the full report to evals/benchmarks/results/BENCHMARK.md

Mode 2: Static Check

When user says /sf-eval --check <file> or /sf-eval check <file>:

Run bash evals/checks/static-checks.sh <file> and show the results.

Mode 3: Score Custom Code

When user provides their own code and asks to evaluate it:

Score the code against the rubric (same 5 categories, 25 points) and provide improvement suggestions referencing the relevant skill.

Available Benchmark Tasks

Read evals/benchmarks/tasks.json for the full list. Tasks cover:

• apex-trigger-bulk — Trigger with handler pattern and bulkification
• apex-batch-cleanup — Batch Apex with error handling
• apex-rest-api — REST endpoint with security
• apex-callout-service — Named Credentials + Queueable
• test-trigger-handler — Comprehensive test class
• test-callout-mock — HttpCalloutMock patterns
• soql-complex-query — Aggregate + optimization
• soql-dynamic-search — Dynamic SOQL without injection
• lwc-record-list — LWC with LDS + error states
• flow-opportunity-automation — Flow XML with bypass
• security-audit-apex — Fix security violations
• schema-custom-object — Metadata XML generation
• deploy-cicd-pipeline — GitHub Actions for SF
• data-migration-plan — Bulk API + relationships
• apex-platform-events — Event-driven architecture

Critical Rules for Baseline Generation

When generating the "baseline" (no skills) code, you MUST intentionally produce typical generic LLM output:

• Use public class (no with sharing)
• Skip WITH USER_MODE in SOQL
• Skip stripInaccessible on DML
• Put logic directly in the trigger body (no handler)
• May have SOQL inside simple loops
• Skip null checks and error handling
• Use basic patterns without Salesforce-specific optimizations

This is NOT about writing bad code on purpose — it's about writing code the way a generic AI would without Salesforce domain expertise. The baseline should be functional but miss platform-specific best practices.

Workflow

1. Identify eval mode (benchmark, static check, or custom code)
2. Read tasks.json and rubric.md
3. Generate baseline and with-skills code
4. Score both against rubric
5. Output formatted comparison report
6. Save to evals/benchmarks/results/BENCHMARK.md if running full benchmark
