What's new in v0.4

v0.4.0 replaces the single llm-mcp shim with direct backends and makes kairos an MCP server. Highlights:

• Direct model backends - stub, ollama, openai, anthropic, and openai_compat.
• MCP server mode - kairos mcp serve exposes seven tools to Cursor, Claude Desktop, and custom MCP clients.
• Safer default - KAIROS_LLM_BACKEND defaults to stub; mcp is removed with a clear migration error.
• Audit gates closed - Ruff, mypy, Bandit, strict pip-audit, Radon, Semgrep, MCP smoke, live Ollama, and KAI2 regression report are required CI checks.

Full migration notes: docs/UPGRADING.md. MCP setup: docs/MCP.md.

Install

pip install kairos-agent

That's it. By default kairos uses the deterministic stub backend. Point it at Ollama, OpenAI, Anthropic, or any OpenAI-compatible server when you want live model calls.

uv tool install kairos-agent

kairos looks at your task, queries its wiki of agent techniques, and tells you which pattern to run: RAG, ReAct, or Reflexion. Then it actually runs it.

Why kairos

You've read the LLM techniques. CoT, ReAct, Reflexion, ToT, HyDE, rerank — twenty patterns each with a paper, each with a use case, each easy to forget the morning you're three coffees into a real problem.

Most "LLM wikis" turn this into a static reading list. kairos turns it into a runtime decision. The wiki is the agent's playbook:

• Ingest raw sources (papers, transcripts, your own notes) → LLM-curated wiki pages.
• Query the wiki with natural language; answers cite real pages with [[wikilinks]].
• Lint for contradictions, stale claims, and gaps. The wiki gets smarter with every run.
• Run any task — kairos picks the right technique by reading its own wiki, then executes it.

Three patterns ship with working runners (RAG, ReAct, Reflexion). The other 18 are documented and ready to be promoted from doc-only to runnable. You can extend it.

Quickstart

# 1. Bootstrap a project. Copies 21 seed concept pages.
kairos init my-wiki && cd my-wiki

# 2. Ingest a source.
kairos ingest research/karpathy-llm-wiki-gist.md

# 3. Ask a grounded question.
kairos query "When should I use ReAct over RAG?"

# 4. Lint the wiki.
kairos lint

# 5. Run a task — kairos auto-selects the technique.
kairos run "Search the docs for caching, then summarize"

# 6. Or pick the technique manually.
kairos run "Iteratively refine this paragraph" --technique reflexion

Every run logs to .kairos/kairos.db (SQLite). Every page lives in plain markdown. Every wikilink survives git diff.

Three layers, mirroring Karpathy's LLM Wiki gist:

1. raw/ - your immutable inputs (papers, articles, transcripts). Source of truth.
2. wiki/ - LLM-generated, human-curated markdown pages. Lives in git.
3. AGENTS.md - the schema. Tells future LLM passes how the structure works.

See docs/architecture.md for the full diagram.

The wedge: executable wiki, not passive notes.

Per-project config lives in .kairos/config.toml. Run kairos doctor to see resolved values.

Roadmap

• v0.4 (now) — direct providers, kairos mcp serve, required audit gates.
• v0.5 — remove the compatibility kairos.llm.mcp_client import shim and expand provider cassettes.
• v1.0 — Plugin runners (pip install kairos-runner-tot), web preview server.

See CHANGELOG.md for what landed in each release.

The wiki pattern is straight out of Andrej Karpathy's LLM Wiki gist. The README structure follows jcode for the install-first / demo-first style. The technique catalog stands on the shoulders of every paper cited in the seed pages.
