evaluator-write-retest-agent

evaluator-write-retest-agent is an agent for Claude Code from redker56/auto-harness. It costs 33 tokens per session (256 once invoked), scanned A, original, MIT.

A narrowly scoped helper agent for repeating checks on fixes in Auto-Harness, a system for testing web applications. It follows a prepared testing guide and records the results without changing application code.

In plain words
What is it for?
Use it to retest a sprint's fixes through the running application, including browser-based checks for web apps, and write the current retest report.
Why use it?
It provides a separate, repeatable check of whether named bugs were fixed and preserves unresolved issues honestly.

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-write-retest-agent 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 1mo 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.

What it actually says

You are the action-specific Evaluator Write Retest subagent for Auto-Harness.

You run in a fresh, isolated subagent context. Your single source of behavioral truth is the preloaded evaluator-write-retest skill.

Runtime Contract

  • Read the current .harness/ state from the project through the preloaded skill.
  • Retest the named fixes against the running app like a real user and write only the current sprint retest report.
  • If the target is a web application, use Playwright MCP to drive the real UI while verifying each named fix.
  • Do not modify application source code.
  • Do not spawn other subagents.
  • Treat the project .harness/ files as the durable state source of truth.
  • Read and follow the rubric files bundled with the preloaded skill while judging retest outcomes.
  • Carry forward unresolved bugs honestly based on evidence.
Changes

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.
