2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its author says it does
Copied from the file, not written here
Use when the user asks a research question, wants to explore a topic, compare options, or needs to investigate something before making a decision. Sets up a structured research folder with living documents and uses sub-agents for parallel exploration. Use when: user says "research X", "look into Y", "compare A vs B", "what are our options for", "investigate", "explore", or asks a question that needs multiple sources to answer well.

The Rule
Write things down as you go. Chat history is not memory. After 20+ turns you won't remember turn 3. The file system is your working memory.
Setup
When a research topic arrives:
- Create a kebab-case folder for the topic (e.g.
oauth-token-refresh/) - Create
summary.mdimmediately. This is the living document. Update it as you go, not at the end. - Ask the user for depth:
- Quick - a few searches, one file with the answer
- Standard - multiple sources, structured summary, key findings (default)
- Deep dive - comprehensive exploration, comparisons, trade-off analysis
The File System
| File | Purpose |
|---|---|
summary.md | Living synthesis. Always exists, always current. Lead with the answer. |
notes.md | Raw findings, quotes, data points. Write as you discover, not at the end. |
sources.md | URLs with one-line annotations. Every claim should be traceable. |
scratch.md | Hypotheses, open questions, thinking out loud. |
comparison.md | Side-by-side analysis when comparing options. |
Keep it flat. No build system, no subdirectories, just markdown.
The Loop
GATHER CONTEXT -> SYNTHESIZE -> VERIFY -> REPEAT
Gather
- Preview large sources before loading them. Filter before reading.
- Save relevant quotes and data points to
notes.mdas you find them. - Log every URL to
sources.mdwith a one-line annotation.
Synthesize
- Update
summary.mdafter each significant finding, not at the end. - If context gets confused: read the topic folder files to recover state. Don't replay the conversation.
Verify
- Are sources credible and recent? Do they agree or conflict?
- Does the synthesis actually answer the question?
- Are claims sourced? Are uncertainties called out explicitly?
Use the right tool level
| Need | Use |
|---|---|
| Specific lookup (one page, one fact) | Tools directly (WebFetch, Grep, Read) |
| Filter/parse/chain operations | Bash with pipes, save intermediates to files |
| 2+ independent questions in parallel | Sub-agents, each with a focused sub-question and a file path to save results to |
Sub-agent guidance
| Depth | Sub-agents |
|---|---|
| Quick | None. Just do it inline. |
| Standard | Optional. When 2+ independent threads exist. |
| Deep dive | Expected. Fan out, then synthesize their results. |
Each sub-agent gets: one specific sub-question, a file path to save results to (in the topic folder), and any relevant context (point to files, don't paste walls of text).
Writing Style
- Write like you're explaining to a smart colleague, not writing a textbook
- Lead with the answer or recommendation, then back it up
- Use tables for comparisons
- Include code snippets when they clarify faster than prose
- If something is uncertain or contested, say so explicitly
- End every
summary.mdwith a "So what?" section: what should we actually do with this?
