exp-eval

exp-eval is a skill for Claude Code from Lambenthan/empiricalwiki. It costs 34 tokens per session (3,770 once invoked), scanned A, original, MIT.

An experiment-results review workflow that turns completed experiment findings into updates to research claims, ideas, and their relationship graph.

In plain words
What is it for?
Use it on completed experiments. It updates claim confidence and evidence, marks linked ideas as validated or failed when appropriate, records claim changes, and rebuilds graph context and open-question files.
Why use it?
It provides a structured decision about whether results support, partly support, reject, or fail to resolve a claim, instead of leaving findings disconnected from the research notes.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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

exp-eval 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.

/exp-eval

将已完成实验的结果转化为 wiki 知识更新。 Review LLM 作为 impartial judge(遵循 cross-model-review),独立评估实验结果对目标 claim 的影响。 4 种判决路径:supported → claim↑ + idea validated / partially_supported → 补充实验 / not_supported → claim↓ + idea failed / inconclusive → debug。 自动更新 claims 的 confidence 和 evidence、ideas 的 status、graph edges。

Inputs

  • experiment:wiki/experiments/ 中的 slug(status 必须为 completed
  • --auto(可选):自动模式,不暂停等待用户确认 wiki 更新(用于 /research 调用)

Outputs

  • wiki/claims/{slug}.md — 更新 confidence、status、evidence 列表
  • wiki/ideas/{slug}.md — 更新 status(validated/failed)、pilot_result、failure_reason
  • wiki/experiments/{slug}.md — 填充 ## Claim updates section
  • wiki/graph/edges.jsonl — 新增 supports/invalidates 边
  • wiki/graph/context_brief.md — 重建
  • wiki/graph/open_questions.md — 重建
  • wiki/log.md — 追加日志
  • VERDICT_REPORT(输出到终端)— 判决结果、wiki 变更摘要、下一步建议

Wiki Interaction

Reads

  • wiki/experiments/{slug}.md — 实验结果:outcome、key_result、metrics、Results section
  • wiki/claims/{target-claim}.md — 目标 claim 当前状态:status、confidence、evidence 列表
  • wiki/ideas/{linked-idea}.md — 关联 idea 当前状态
  • wiki/experiments/*.md — 同一 claim 的其他实验结果(综合评估)
  • wiki/graph/context_brief.md — 全局上下文
  • .claude/skills/shared-references/cross-model-review.md — 审稿独立性原则

Writes

  • wiki/claims/{target-claim}.md — 更新 status、confidence、evidence、date_updated
  • wiki/ideas/{linked-idea}.md — 更新 status、pilot_result、failure_reason、date_resolved
  • wiki/experiments/{slug}.md — 填充 ## Claim updates section
  • wiki/graph/edges.jsonl — 新增 supports 或 invalidates 边
  • wiki/graph/context_brief.md — 重建
  • wiki/graph/open_questions.md — 重建
  • wiki/log.md — 追加操作日志

Graph edges created

  • supports:experiment → claim(实验支持该 claim)— verdict = supported 或 partially_supported
  • invalidates:experiment → claim(实验否定该 claim)— verdict = not_supported

Workflow

前置

  1. 确认工作目录为 wiki 项目根(包含 wiki/raw/tools/ 的目录)
  2. 确认实验 status == completed(未完成的实验不能评判)

Step 1: 加载上下文

  1. 读取实验页面 wiki/experiments/{slug}.md
    • outcome(succeeded/failed/inconclusive)
    • key_result
    • target_claim slug
    • linked_idea slug
    • metrics 和完整 Results section
    • hypothesis

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.

exp-eval is a skill published in the GitHub repository Lambenthan/empiricalwiki (82 stars, last pushed 2mo ago), licensed MIT. It adds 34 tokens to every session and 3,770 once invoked, about $0.0002 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.
