unlimited-skills 0.6.6

A local skill retrieval library for coding agents: lexical search, vector sidecar search, warm daemon mode, and learning-loop logs.

Unlimited Skills

Unlimited Skills is a local-first skill memory and retrieval layer for coding agents. It keeps large skill libraries out of the agent context and retrieves the small, relevant skill context only when it is useful.

This is v0.6.6 of the free MIT local core. There is no telemetry, no hosted dependency for local use, and nothing for sale in this release. The project is still pre-1.0, so APIs and JSON output may change before 1.0.

Use unlimited-skills==0.6.6 or newer after this release is published. The 0.6.0 package was uploaded to PyPI but was not tagged or released because the published verifier caught a CLI contract issue after upload.

Install

pip install unlimited-skills
unlimited-skills quickstart

To avoid earlier uploaded-but-not-current artifacts explicitly, pin the accepted v0.6 alpha floor:

pip install --upgrade "unlimited-skills>=0.6.6"

For hybrid/vector search:

pip install "unlimited-skills[vector]"
unlimited-skills vector-reindex

What Quickstart Proves

unlimited-skills quickstart is the first-value path for a clean install:

• imports the bundled ECC and Superpowers packs when your local library is empty;
• indexes the local skill library;
• runs a first search so you can see retrieval working;
• measures local MCP context savings when a Claude Code config is available;
• prints local next steps without uploading prompts, schemas, configs, or skill bodies.

The package smoke for this release verifies the wheel in a fresh virtual environment: unlimited-skills --version, quickstart, suggest, mcp savings, feedback prepare, learning-summary --events, and roi receipt all run from the installed package. The v0.6.6 package smoke also verifies retrieval precision and onboarding from a clean wheel install: weak matches stay silent, mixed-language prompts request an English-keyword rescue, quickstart completes missing bundled collections without touching local skills, and the source release-gate verifier passes.

Measured, Not Promised

Current release-gate measurements on the bundled library:

• skill retrieval eval: top-1 0.933, top-3 0.967, false positives 0;
• MCP lab benchmark: 90,420 bytes of direct tool schemas versus 1,268 bytes behind the Unlimited Tools gateway.

Your local results depend on your installed skills and MCP servers. Run unlimited-skills mcp savings --json to measure your own configuration.

Local-First Boundaries

• No telemetry or automatic uploads.
• No skill execution by the library.
• The Claude Code prompt hook may start the optional warm-search daemon on loopback; it never binds LAN/remote or uploads prompt data. Set UNLIMITED_SKILLS_NO_AUTOSERVE=1 only for restricted runtimes.
• No paid, hosted, Team, Pro, Business, or Enterprise feature is required for local search, quickstart, suggestion, indexing, or MCP savings.
• Hosted/registered catalog and team surfaces are early alpha paths documented in the repository; they are not required for the local core.
