Sammy
Works in VS Code, Cursor & every fork

A full-stack AI/ML engineer in your editor

Sammy Coding Agent doesn't just autocomplete. It consults and implements — RAG, agents, evals, guardrails, model selection — and scaffolds production AI bots on the Sammy framework, end to end, right where you work.

Sammy — Coding Agent

Add retrieval over my PDF manuals so users get grounded answers.

Loaded skill: rag-architecture

Designed pipeline — chunking → embeddings → pgvector

Wrote lib/rag/ingest.ts

Wrote app/api/chat/route.ts

Ran eval — answers grounded with citations

Reviewing changes…

Done. RAG is wired and passing — try a question.

What it does

Not a chatbot — an engineer

Consult it on the hard AI/ML decisions, then have it implement them in your codebase.

Skills, on demand

Expert playbooks — RAG, agent design, evals, guardrails — load only when your task needs them, so every turn stays fast and focused.

Current docs, not stale memory

It fetches live library docs to code against today's APIs and versions — past the model's knowledge cutoff, not from memory.

RAG architecture

Chunking, embeddings, vector store, retrieval + rerank, and grounded generation with citations — designed and wired in your repo.

Agent design

Tool schemas, routing, approval and safety, retries, context budgeting — the patterns that actually hold up in production.

Evals that gate

Golden sets, LLM-as-judge rubrics, and CI regression gates so your assistant's quality is measured, not hoped for.

Builds bots on Sammy

The moat: scaffold → wire your tools → eval a production AI bot on the Sammy framework, end to end, from inside the editor.

Approval-gated edits

Every write and command is previewed and gated. Read-only steps run free; nothing changes on disk without your OK.

Self-review built in

After real work, a fast critic re-checks the result and corrects concrete mistakes before the agent calls it done.

The moat

It builds on the Sammy platform — so you can ship the bot, not just prototype it

The agent is the front door. Behind it is the Sammy framework and cloud: model routing, billing, and a runtime your AI bots actually run on. Ask the agent to build a bot and it scaffolds the config, wires your tools, and evaluates it — on the same platform you deploy to.

// the bot-builder workflow, run for you

sammy init — scan the codebase

sammy generate — tools + agents

wire to your APIs — approval-gated

sammy eval — score & refine

✓ Production AI bot, on the platform you deploy to

Straight about scope

What it will and won't do

Implements

Implements in your workspace

RAG, agents, eval harnesses, guardrails, observability, and full-stack streaming AI features — written and wired in your repo.

Writes

Writes the scripts it can't run

Fine-tuning, dataset-prep, and serving configs (LoRA/PEFT, vLLM/TGI). It authors them — it can't run GPU training in your editor.

Note

Honest about the model

Built on fast open models, so it's text-only today — no image input yet. It tells you when something needs your infra or a human call.
