Unlimited Skills

Unlimited Skills is governed skill infrastructure for AI agent fleets. Its free MIT local core keeps large skill libraries out of standing context, retrieves the relevant capability on demand, and security-gates supported installation paths before skill files are copied.

This is v0.6.9, the stable pre-1.0 local core. Local use has no telemetry or hosted dependency. Business and Enterprise Fleet are separate hosted control-plane capabilities and are not required for local search or installs.

Use unlimited-skills==0.6.9 for the stable security-gated Fleet client. The 0.6.9rc12 candidate remains immutable release history.

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>=0.6.9"

For hybrid/vector search:

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

Optional Local Business Context

An owner can configure a private local JSON-over-stdio adapter so card-mode suggest returns the chosen skill plus cited business references. The public package ships the bounded transport and policy boundary—not a company database, credentials, or hosted dependency.

unlimited-skills context doctor --json
unlimited-skills context retrieve "current source-backed operating context" --json

Retrieved text is retrieval_only, treated as data rather than instructions, and marked internal. no_context never means verified absence. The Claude Code Stop hook never derives evidence from assistant prose. It only forwards an explicit, bounded signed receipt supplied by a trusted host field or an owner-controlled inbox. The private provider owns signature authentication, acceptance, quarantine, idempotency, and durable writes.

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 v0.6.9 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 release 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.
• No business provider is enabled by default. When explicitly configured, task queries and explicit signed completion receipts go only to that trusted local command.
• 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 Business and Enterprise Fleet capabilities are opt-in and separately operated; they are not required for the local core.
