synthesize-brief

synthesize-brief is a skill for Claude Code, Codex from understudy-ai/understudy. It costs 16 tokens per session (193 once invoked), scanned A, original, MIT.

A workflow for turning research findings and supporting files into a concise summary and short brief.

In plain words
What is it for?
It helps combine findings, highlights, limitations, and context into summary.json and brief.md files, with ratings for usefulness, polish, and first-use clarity.
Why use it?
It makes incomplete or scattered findings easier to turn into a clear, usable conclusion while noting uncertainty.

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

synthesize-brief 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 5d 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.

What it actually says

synthesize-brief

Overall Goal

Convert the exploration context into a concise verdict, summary packet, and short brief.

Inputs

  • findings.md
  • highlights.json
  • limitations.json
  • context.md

Outputs

  • summary.json
  • brief.md

Staged Workflow

  1. Merge the baseline and exploration findings into a concise summary.
  2. Score usefulness, polish, and first-run clarity.
  3. Write summary.json and brief.md.

Tool Route Options

  • shell for deterministic file generation
  • memory for reusing prior scoring language

Detailed GUI Replay Hints

  • None. This stage should stay artifact-first and deterministic.

Failure Policy

  • If findings are incomplete, produce a conservative summary with explicit uncertainty notes.
Changes

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.
