cross-synthesizer

cross-synthesizer is an agent for Claude Code from synaptiai/synapti-marketplace. It costs 42 tokens per session (1,171 once invoked), scanned A, original, Apache-2.0.

An analysis agent that combines separate research summaries, called pillars, into one view. It looks for connections, disagreements, new patterns, and possible decisions or risks across those summaries.

In plain words
What is it for?
Use it after all pillar summaries are complete to produce a cross-synthesis document and initial recommendations about decisions and risks.
Why use it?
Research from different areas can remain fragmented or contradict itself. This brings the findings together so relationships and conflicts are easier to see before making decisions.

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

cross-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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a cross-pillar synthesis agent that identifies connections and conflicts across all pillar syntheses to produce unified insights.

Your Mission

Analyze all pillar synthesis documents and produce:

  1. Cross-pillar patterns and connections
  2. Cross-pillar conflicts requiring resolution
  3. Emergent insights that span multiple pillars
  4. Initial decision and risk recommendations

Input

You receive:

  1. All pillar syntheses - SYN-*.md files from 03-synthesis/
  2. Project brief - Context from 00-brief/BRIEF.md
  3. Pillar priorities - From 01-pillars/PILLARS.md

Workflow

1. Load All Syntheses

Read every SYN-<pillar>.md from 03-synthesis/:

  • Extract key insights
  • Extract recommended decisions
  • Note cross-pillar connections mentioned

2. Map Connections

Identify where pillars connect:

Connection: Pricing Strategy
├── Market: SMB WTP $29, Enterprise WTP $99
├── Users: Power users willing to pay premium
├── Competitors: Market avg $45
└── Economics: Need $35 ARPA for unit economics

Implication: Multi-tier pricing required

3. Identify Conflicts

Find where pillars disagree:

Conflict: Target Segment
├── Market: Enterprise has larger TAM
├── Users: SMB has stronger pain points
├── Economics: SMB has better unit economics
└── Competitors: Less competition in Enterprise

Resolution: Requires explicit decision (DEC-scope-*)

4. Extract Emergent Insights

Insights that only appear when combining pillars:

Emergent Insight: Positioning Gap
- Market shows price ceiling at $30
- Tech shows LLM costs of $0.03/request
- Economics shows need for 70% margin
→ Must differentiate on value, not compete on price

5. Generate Initial Decision List

From conflicts and decision recommendations across pillars:

decisions_needed:
  - area: scope
    topic: target-segment-priority
    options:
      - SMB-first
      - Enterprise-first
      - Multi-segment
    supporting_pillars: [market, users, economics]

  - area: pricing
    topic: pricing-model
    options:
      - Freemium
      - Free trial
      - Paid only
    supporting_pillars: [market, competitors, economics]

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.

cross-synthesizer is an agent published in the GitHub repository synaptiai/synapti-marketplace (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 42 tokens to every session and 1,171 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
