What it does
Concept Synthesis is an agent skill from inbrainfun/inbrain. Deduplicate and synthesize raw concept stubs into a tiered intellectual map (T1 Canon to T4 Riff), tracing idea evolution across sources over time. Transforms thousands of raw concept pages into a curated intellectual fingerprint.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
Example prompts
- “/concept-synthesis”
What it can do on your machine
Read from SKILL.md and the folder at commit 5231990. 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 (its code samples are markdown and bash).
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
Concept Synthesis loads about 2k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 451 words of instructions outside code blocks.
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 451 words (~2,032 tokens).
“Many ingestion pipelines (signal-detector, idea-ingest, voice-note-ingest) create a concept page for every idea mentioned. Over months this produces:”

Questions about Concept Synthesis
What does Concept Synthesis do?
Deduplicate and synthesize raw concept stubs into a tiered intellectual map (T1 Canon to T4 Riff), tracing idea evolution across sources over time. Concept Synthesis is an agent skill from inbrainfun/inbrain. Deduplicate and synthesize raw concept stubs into a tiered intellectual map (T1 Canon to T4 Riff), tracing idea evolution across sources over time.
How do I install Concept Synthesis in Claude Code?
Run `npx skills add inbrainfun/inbrain --skill concept-synthesis -a claude-code`. Or copy the skill folder (skills/concept-synthesis in inbrainfun/inbrain) into .claude/skills/concept-synthesis in your project. Claude Code loads it when a task matches its description.
How do I install Concept Synthesis in Codex?
Run `npx skills add inbrainfun/inbrain --skill concept-synthesis -a codex`. Or copy the skill folder (skills/concept-synthesis in inbrainfun/inbrain) into .agents/skills/concept-synthesis in your project. Codex loads it when a task matches its description.
Can I use Concept Synthesis in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add inbrainfun/inbrain --skill concept-synthesis -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/concept-synthesis, .gemini/skills/concept-synthesis, .github/skills/concept-synthesis and .opencode/skills/concept-synthesis in your project.
What does Concept Synthesis need to run?
SKILL.md names no scripts, command-line tools or credentials: Concept Synthesis is instructions for the agent only.
Does Concept Synthesis access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Concept Synthesis safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Concept Synthesis use?
Concept Synthesis has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Concept Synthesis use?
About 2k tokens (SKILL.md is roughly 8.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Concept Synthesis?
Skills that share tags, products or a category with Concept Synthesis: Concept Synthesis (garrytan/gbrain, 31k stars), Edge Concept Synthesizer (tradermonty/claude-trading-skills, 3k stars), Research Synthesize (ruvnet/ruflo, 74k stars) and JavaScript Concept Page Workflow (leonardomso/33-js-concepts, 67k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Concept Synthesis?
inbrainfun (a GitHub user) maintains it in inbrainfun/inbrain, which has 142 GitHub stars. The repository holds 52 skills in this directory. The repository was last updated on July 17, 2026.
