Agent Benchmark Framework

Without benchmarks, we cannot know whether agent changes improve or degrade quality. This skill defines how to measure, track, and protect agent performance.

When to Activate

Before and after modifying any agent definition file
When adding a new skill that an agent depends on
Periodic quality audits (weekly/monthly)
When a user reports degraded agent output
Before promoting an agent from experimental to production

Core Concepts

Why Benchmarks Matter

Agent quality degrades silently. A prompt tweak that improves one response can break ten others. Without a baseline to compare against, every change is a guess. Benchmarks make quality visible and regressions detectable.

Benchmark Types

Type	Scope	Cost	Frequency
Prompt Benchmark	Single agent, single task	Low	Every agent change
Task Benchmark	End-to-end scenario	Medium	Feature changes
Regression Suite	All critical agents	High	Weekly / before release

Scoring Rubric Template

Each agent has its own rubric file. The template:

## [Agent Name] Scoring Rubric

### Completeness (0-30 points)
Did the agent find everything it should have found?

- Found all expected issues: 30
- Missed 1 non-critical issue: 22
- Missed 1 critical issue: 10
- Missed 2+ issues: 5
- Found nothing when issues exist: 0

### Accuracy (0-30 points)
Were the findings correct? No false positives?

- All findings verified correct: 30
- 1 false positive: 22
- 2 false positives: 12
- 3+ false positives: 5
- Majority of findings are wrong: 0

### Actionability (0-20 points)
Did the agent give concrete, implementable fixes?

- Clear fix with file/line reference: 20
- Clear fix without location: 14
- Vague suggestion (refactor this): 7
- No fix suggested: 0

### Format Compliance (0-20 points)
Did the output follow the agent's output contract?

- Matches contract exactly (VERDICT + sections): 20
- Minor deviation (missing one section): 12
- Major deviation (no VERDICT): 5
- Unstructured free text: 0

Ground Truth Format

Ground truth files define what a correct agent response must contain:

{
  "fixture": "missing-error-handling.ts",
  "agent": "code-reviewer",
  "required_findings": [
    {
      "id": "missing-try-catch",
      "severity": "HIGH",
      "description_contains": ["error handling", "try", "catch"],
      "location_hint": "fetchUserData"
    }
  ],
  "forbidden_findings": [],
  "required_verdict": "FAIL",
  "min_score": 70
}

Scoring Logic

How a Run Is Scored

1. Load fixture (input code / task)
2. Run agent with fixture as input
3. Parse agent output
4. Check required_findings: each found = +completeness points
5. Check forbidden_findings: each false positive = -accuracy points
6. Check verdict matches required_verdict
7. Check format follows output contract
8. Sum scores → final 0-100
9. Compare against min_score threshold

Score Interpretation

Score	Status	Action
90-100	EXCELLENT	No action needed
75-89	GOOD	Minor tuning optional
60-74	WARN	Investigate degradation
40-59	POOR	Agent needs rework
0-39	CRITICAL	Block deployment

Running Benchmarks

Run All Benchmarks

# Full suite
node ~/.claude/benchmarks/run.mjs

# Output: results/run-{timestamp}.json

Run Single Agent

# Benchmark one agent
node ~/.claude/benchmarks/run.mjs --agent code-reviewer

# With verbose output (shows actual vs expected per fixture)
node ~/.claude/benchmarks/run.mjs --agent code-reviewer --verbose

Compare Against Baseline

# Compare latest run against saved baseline
node ~/.claude/benchmarks/run.mjs --compare

# Compare specific run against specific baseline
node ~/.claude/benchmarks/run.mjs \
  --compare results/run-2026-03-26.json \
  --baseline baselines/code-reviewer-2026-03-01.json

Update Baseline

Only run this after verifying an improvement is real:

# Promote latest results to new baseline
node ~/.claude/benchmarks/run.mjs --baseline update

# Creates: baselines/{agent}-{date}.json

Regression Detection Rules

A regression is triggered when:

Score drops more than 10 points on any single fixture
Average score drops more than 5 points across all fixtures for an agent
A previously PASS fixture becomes FAIL
Format compliance drops below 80 (agent stopped following output contract)

Regression Report Format

REGRESSION DETECTED: code-reviewer

Fixture: sql-injection.py
  Baseline score:  88
  Current score:   61
  Delta:           -27 (CRITICAL)

  Missing finding: SQL injection in execute_query() line 14
  Root cause: Agent definition changed, removed security focus

  Recommendation: Revert agent change or add SQL injection examples

Metrics Tracked Per Agent

Metric	Formula	Target
accuracy	correct_findings / total_findings	>= 0.85
completeness	found_issues / total_issues	>= 0.90
false_positive_rate	false_positives / total_findings	<= 0.10
format_compliance	correct_format_runs / total_runs	>= 0.95
response_time_p50	median seconds to complete	<= 30s
response_time_p95	95th percentile seconds	<= 60s
token_usage_avg	average tokens per run	tracked only
pass_rate	fixtures scoring above min_score	>= 0.80

Per-Agent Benchmark Definitions

code-reviewer

Fixtures: 6 (2 missing error handling, 2 code smell, 1 SQL injection, 1 clean code) Pass threshold: 70/100 Critical findings: error handling, injection vulnerabilities, magic numbers Non-critical findings: naming conventions, comment quality

security-reviewer

Fixtures: 8 (hardcoded secrets, injection flaws, auth bypass, safe code) Pass threshold: 75/100 Zero tolerance: must find all HIGH/CRITICAL security issues Acceptable miss: LOW severity cosmetic issues only

verifier

Fixtures: 4 (passing build, type errors, failing tests, lint errors) Pass threshold: 80/100 Critical: must correctly identify PASS vs FAIL state Scoring focus: verdict accuracy over prose quality

sleuth (bug investigator)

Fixtures: 5 (null pointer, race condition, wrong logic, correct code) Pass threshold: 65/100 Critical: must identify root cause, not just symptom Scoring focus: root cause analysis depth

Benchmark Authoring Guide

Writing a Good Fixture

A good benchmark fixture is:

Realistic - Code that could exist in a real project
Focused - Tests one specific thing the agent should find
Unambiguous - The ground truth is objectively correct
Minimal - No unnecessary noise that could confuse the agent

Example: Good Fixture (code-reviewer)

// fixtures/code-reviewer/missing-error-handling.ts
// BENCHMARK: Agent must find missing error handling in fetchUser

async function fetchUser(id: string) {
  const response = await fetch(`/api/users/${id}`)
  const data = await response.json()
  return data
}

export default fetchUser

Ground truth:

{
  "required_findings": [{
    "severity": "HIGH",
    "description_contains": ["error handling", "network", "try"],
    "location_hint": "fetchUser"
  }],
  "required_verdict": "FAIL",
  "min_score": 70
}

Example: Bad Fixture (too complex)

Do not create fixtures with 10 different issues. The agent may find 7, miss 3, and you cannot tell if the misses are regressions or noise. One fixture = one primary concern.

Integration with Canavar

When a benchmark run produces a regression, log it to the Canavar error ledger:

node ~/.claude/hooks/dist/canavar-cli.mjs errors

Canavar cross-training means a regression in code-reviewer will inject a warning into all producer agents that use code-reviewer output, preventing cascading quality failures.

Quick Reference

# Before changing an agent:
node ~/.claude/benchmarks/run.mjs --agent code-reviewer --save-as before

# After changing the agent:
node ~/.claude/benchmarks/run.mjs --agent code-reviewer --compare before

# Full regression check:
node ~/.claude/benchmarks/run.mjs --compare --fail-on-regression

# Update baselines after confirmed improvement:
node ~/.claude/benchmarks/run.mjs --baseline update

Remember: A benchmark suite that is never run is decoration. Run benchmarks before every agent change. Protect quality proactively, not reactively.
