The problem

Your agents keep making the same mistakes.

Your team has spent months building conventions — how to write migrations, how to handle API versioning, how to structure tests. That knowledge lives in your heads, in scattered CLAUDE.md files, in code review comments that get forgotten.

Every Claude Code session starts from zero.The agent doesn't know your rules until something goes wrong. Then someone opens a PR that violates three conventions at once and the review becomes a lecture.

The alternative — stuffing everything into CLAUDE.md — costs thousands of tokens per session whether the agent needs it or not. You're paying for context that's irrelevant 90% of the time.

📂
Scattered CLAUDE.md files
Every repo has its own version. They drift, contradict each other, and nobody knows which one is canonical.
🪙
Token waste on every session
Loading all your conventions upfront costs tokens whether they're relevant or not. You pay for context the agent ignores.
🔁
Same mistakes, every session
The agent doesn't know your team changed the migration pattern last month. It uses the old one. Again.
👤
Knowledge lives in heads, not systems
Senior engineers review AI output and catch violations by memory. That doesn't scale and burns out the people you can't afford to lose.
How it works

From scattered files to one source of truth.

Three steps. Under four minutes to set up. Works with every project you already have.

1
Author your skills
Write skills and rules in plain markdown — or import your existing CLAUDE.md files. Organize them by scope: org-wide, team, or project-specific. Set which ones load automatically and which are available on demand.
2
Connect your project
Run syphin init in any project directory. Syphin installs the MCP server and writes a config file. Claude Code picks it up automatically — no other setup required. Works in monorepos too.
3
Watch it work
The agent searches your registry before starting work, loads only what's relevant, and follows your conventions — session after session. The Sessions tab shows exactly what got loaded, what got searched, and what happened.
Live demo

From terminal to live session in 90 seconds.

This is what actually happens when a developer opens Claude Code in a Syphin-connected project.

Features

Everything your team needs to build with confidence.

The whole system, not just a file host.

🔍
Semantic skill search
Agents find relevant skills by describing what they're doing — not by guessing the right keyword. The same vector search powers both agent discovery and human authoring.
Token-efficient
🏗️
Scope inheritance
Rules cascade from org → workspace → project. Define your Python conventions once at the org level. Override for specific teams or projects. No duplication.
📡
Live session telemetry
See exactly what every agent loaded, searched, and ignored — session by session. The Sessions tab tells you whether your skills are actually working.
⚡
Local caching
Skill bodies are cached on the developer's machine after the first load. Published versions are immutable — the cache never expires. Fast offline, fast always.
🔗
GitHub integration
Relevant skills surface as PR comments. CLAUDE.md files sync automatically. New repos get connected without anyone thinking about it.
Builder+
📊
Skill A/B testing
Split-test description variants and measure which version gets loaded more often. Turn "does this rule work?" from a guess into a number.
Team+
✍️
Description quality linter
Skills only work if agents can find them. The linter scores your descriptions in real time and shows you what queries will surface each skill.
🔄
Review workflows
Draft, review, approve, publish. Skills go through the same deliberate process as your code — with inline comments and full version history.

Public registry
Browse and import community skills for Prisma, Stripe, FastAPI, React, and more. Contribute your own. Syphin's quality bar means you can actually trust what you import.

What teams are saying.

“We had 14 different CLAUDE.md files across our repos, each one a month out of date. Syphin replaced all of them with one place our whole team actually keeps current.”

“The Sessions tab is what sold me. I can see exactly which skills Claude loaded for any given task. It turned a black box into something I can actually tune.”

“I'm not a developer but I use Claude Code every day to build features. Syphin made it so the agent already knows how our team builds things — I don't have to explain it every session.”
