claude_harness_eng_v1: Agent for Claude Code

.claude/agents/evaluator.md

evaluator is an agent for Claude Code from cwijayasundara/claude_harness_eng_v1. It costs 29 tokens per session (1,462 once invoked), scanned A, original, no licence file.

A skeptical checking agent that runs the application and tests its sprint contract, the agreed list of work and conditions for completion. It uses API tests, Playwright interactions, and schema validation, which checks that data follows the required structure.

In plain words
What is it for?
Use it to check application behavior through APIs and browser actions and to validate response or data schemas.
Why use it?
It tests the running result against explicit criteria instead of trusting that the implementation is complete.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is cwijayasundara/claude_harness_eng_v1's own configuration. It tells Claude Code how to work on claude_harness_eng_v1 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude_harness_eng_v1 configures →

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

evaluator scanned grade A with 1 finding 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 12d 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.

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.
