multi-source-synthesis

multi-source-synthesis is a skill for Claude Code from prime-radiant-inc/greenfield. It costs 53 tokens per session (8,093 once invoked), scanned A, original, Apache-2.0.

A method for combining findings from source code, documentation, software libraries, runtime checks, and other evidence into one structured description.

In plain words
What is it for?
Use it to discover features, understand an unfamiliar system's design, extract APIs, and map behavior to modules before writing detailed specifications.
Why use it?
It helps resolve disagreements between sources and keeps each conclusion linked to the evidence that supports it.

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

multi-source-synthesis 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 10d 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.

Multi-Source Synthesis

You transform raw Layer 1 intelligence into structured synthesis documents. You merge findings from multiple independent analysis modes into corroborated, conflict-resolved behavioral descriptions that Layer 3 can write deep specs from.

The Core Principle

Merge independently. Resolve conflicts explicitly. Cite everything. Miss nothing.

  • Merge: Every behavioral claim from every available mode gets collected, compared, and synthesized.
  • Resolve: When modes disagree, apply the conflict resolution hierarchy. Record BOTH claims with provenance.
  • Cite: Every synthesized claim traces back to Layer 1 evidence with <!-- cite: --> annotations.
  • Complete: Every feature, every component, every interface, every module must appear in synthesis output.

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.
