eval-report

eval-report is a skill for Claude Code, Codex from jmagly/aiwg. It costs 21 tokens per session (1,150 once invoked), scanned A, original, MIT.

A tool that combines agent evaluation results into a quality report. An evaluation result is a recorded check of how well an AI agent performed a task.

In plain words
What is it for?
Use it to produce Markdown or JSON reports, review scores by agent or category, find regressions, filter results by date, and generate improvement recommendations.
Why use it?
It makes scattered evaluation files easier to review and shows score changes, warnings, and agents that need attention. It can also compare results with an earlier report.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

eval-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Evaluation Report

Generate a quality report from accumulated evaluation results.

Research Foundation

  • REF-001: BP-9 - Continuous evaluation of agent performance
  • REF-002: KAMI benchmark methodology for real agentic task evaluation

Usage

/eval-report
/eval-report --output .aiwg/reports/quality-report.md
/eval-report --compare previous-report.json
/eval-report --mode sdlc --format json

Options

Option Default Description
--output stdout Output file path
--compare none Previous report to diff against
--mode all Agent category: sdlc, marketing, forensics, all
--format markdown Output format: markdown, json
--since none Only include results after this date (ISO 8601)
--threshold 0.85 Score below this triggers a warning

Process

  1. Collect Results: Read all eval-*.json files from .aiwg/reports/
  2. Aggregate Scores: Compute per-agent and per-archetype scores
  3. Detect Regressions: Compare against --compare baseline if provided
  4. Rank Agents: Sort by overall score, flag below-threshold agents
  5. Build Recommendations: Surface specific agents and archetypes needing attention
  6. Output Report: Write markdown or JSON to --output or stdout

Agents Needing Attention

# Agent Quality Report

**Generated**: 2026-04-01T10:30:00Z
**Agents Tested**: 58
**Overall Score**: 87%
**Regressions**: 2

## By Archetype

| Archetype | Pass Rate | Trend |
|-----------|-----------|-------|
| #1 Grounding | 92% | ↑ |
| #2 Substitution | 88% | → |
| #3 Distractor | 78% | ↓ |
| #4 Recovery | 90% | ↑ |

## Agents Needing Attention

| Agent | Score | Consecutive Failures | Issue |
|-------|-------|---------------------|-------|
| data-analyst | 72% | 3 | distractor-test |
| api-designer | 79% | 1 | latency regression (+40%) |

## Recommendations

1. Review `data-analyst` context filtering — failed distractor-test 3 consecutive runs
2. Investigate `api-designer` tool selection — latency regression
3. Increase distractor-test scenarios for marketing agents (78% pass rate below 80% target)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

eval-report is a skill published in the GitHub repository jmagly/aiwg (209 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 1,150 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
