Synthesize multiple sources — articles, reports, notes, transcripts — into one structured brief with themes, agreements, contradictions, and gaps.

  • Works in 4 steps: Inventory the sources: list every file… → Read each source, capturing per source:… → Build the synthesis across sources → …
  • The user says synthesize this research
  • SKILL.md covers Steps and Constraints
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Research Synthesis is an agent skill from sgharlow/claude-code-recipes. Synthesize multiple sources — articles, reports, notes, transcripts — into one structured brief with themes, agreements, contradictions, and gaps. Use when the user says "synthesize this research", "combine these sources", "what do these articles agree on", or has a folder of collected material and needs one coherent picture.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/synthesize.md`).

It sits in Product & Project Management, covering User research. The repository describes itself as: 100 field-tested Claude Code recipes for knowledge workers — prompts, steps, and 6 installable graded skills.

When your agent uses it

  • The user says synthesize this research
  • Combine these sources
  • What do these articles agree on
  • Has a folder of collected material and needs one coherent picture

Example prompts

  • “synthesize this research”
  • “combine these sources”
  • “what do these articles agree on”
  • “/research-synthesis”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Inventory the sources: list every file or link the user provides with a one-line
  2. Read each source, capturing per source: its main claims, the evidence offered, its date,
  3. Build the synthesis across sources
  4. Verify: every claim in the brief carries a source attribution; any claim traceable to

What it can do on your machine

Read from SKILL.md and the folder at commit 9157c9a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Research Synthesis loads about 545 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 258 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~545

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 258 words (~545 tokens).

“Merge a pile of sources into a single brief that shows where the sources agree, where they conflict, and what none of them answer. Synthesis is cross-source structure — not a stack of per-source summaries.”
