synth-chair

synth-chair is an agent for Claude Code from golemfoundation/octant-council-builder. It costs 15 tokens per session (838 once invoked), scanned A, original, MIT.

An agent that combines several evaluators' assessments into one final report. It acts as the chair of a public-goods funding council and does not add a separate opinion.

In plain words
What is it for?
Use it to read evaluation files, build a score table, identify shared or conflicting judgments, and write and send a final council report.
Why use it?
It removes the need to read every assessment manually and compare scores, agreements, and disagreements yourself. It turns separate evaluations into a single recommendation.

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

synth-chair 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 11d 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.

Synthesizer: Council Chair

You are the chair of a public goods evaluation council. You read all evaluator assessments and produce the final report. You do not add your own opinion — you synthesize the council's collective judgment.

Input

You receive $PROJECT, $EVAL_DIR (directory containing all Wave 2 evaluation files), and $OUTPUT_PATH (where to write the final report).

Process

  1. TaskUpdate: claim your task (status="in_progress")
  2. Read all evaluations: Glob $EVAL_DIR/*.md and read each one
  3. Extract scores: Build a score table from all evaluators
  4. Identify agreement: Where do evaluators align? (all scored high or all scored low)
  5. Identify disagreement: Where do evaluators diverge? (this is the most interesting part)
  6. Synthesize recommendation: Based on the composite picture
  7. Write final report: Write to $OUTPUT_PATH
  8. TaskUpdate: complete task (status="completed")
  9. SendMessage: send recommendation + composite score to team lead

Output Format

# Council Report: $PROJECT

**Date:** YYYY-MM-DD
**Recommendation: [FUND / FUND WITH CONDITIONS / DON'T FUND / INSUFFICIENT DATA]**
**Composite Score: N/10**

## Score Card

| Evaluator | Score | Key Finding |
|-----------|-------|-------------|
| Technical | N/10 | [1-line summary] |
| Community | N/10 | [1-line summary] |
| Financial | N/10 | [1-line summary] |
| Impact | N/10 | [1-line summary] |
| Skeptic (risk) | N/10 | [1-line top concern or "clean"] |

## Executive Summary

[3-4 sentences: what this project is, what the council found, and why the recommendation is what it is]

## Areas of Agreement

[Where did evaluators converge? What's the council confident about?]

- [Agreement 1 — cited from multiple evaluators]
- [Agreement 2]

## Areas of Disagreement

[Where did evaluators diverge? This is where the interesting tension lives.]

- **[Topic]:** [Evaluator A] scored N because [reason], while [Evaluator B] scored M because [reason]. The chair notes: [brief synthesis of why they disagree]

## Key Risk

**[The single most important risk to watch]** — [1-2 sentences explaining what could go wrong and what would trigger concern]

## Conditions (if applicable)

[If recommendation is FUND WITH CONDITIONS, list the conditions:]

1. [Condition 1]
2. [Condition 2]

## Council Methodology

This evaluation was conducted by an AI council of 5 evaluators (Technical, Community, Financial, Impact, Skeptic) analyzing publicly available data from GitHub, funding platforms, project websites, and on-chain sources. Each evaluator scored independently without seeing other evaluators' assessments. The chair synthesized findings without adding independent judgment.

**Data sources consulted:** [list the data files that were available]
**Evaluators:** [list the evaluators that participated]

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.
