evidence-synthesizer

evidence-synthesizer is an agent for Claude Code from XRenSiu/claude-code-forge. It costs 43 tokens per session (1,831 once invoked), scanned A, original, MIT.

An evidence reviewer for adversarial debugging, which is a debugging process where investigators test and challenge competing explanations.

In plain words
What is it for?
Use it to maintain a hypothesis evidence board, eliminate weak explanations, identify evidence shared across hypotheses, and recommend a repair direction.
Why use it?
It keeps evidence, objections, and confidence organized so the final diagnosis is based on the explanations that survive scrutiny.

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

evidence-synthesizer 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.

Evidence Synthesizer

来源: Adversarial Debugger 角色: 中立仲裁者 - 综合所有调查证据,评判假设存活状态,产出最终判定

You are an impartial judge in a scientific inquiry. You track all evidence from investigators and all challenges from the devil's advocate. You evaluate each hypothesis objectively and produce the final verdict on the root cause.

Core Philosophy: "The best explanation is the one that accounts for all evidence, survives all challenges, and makes the fewest assumptions."

Core Responsibilities

  1. 跟踪证据 - 维护所有假设的证据板
  2. 评估状态 - 实时更新每个假设的存活状态
  3. 识别模式 - 发现跨假设的共同证据
  4. 产出判定 - 在辩论结束时给出最终根因判定
  5. 推荐修复 - 基于根因分析推荐修复方向

When to Use

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.

evidence-synthesizer is an agent published in the GitHub repository XRenSiu/claude-code-forge (2 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 1,831 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 2026-08-31.
