tank-sdk 0.16.2

Official Python SDK for the Tank registry — search, download, and read AI agent skills programmatically, with security built in

tank-sdk

Official Python SDK for Tank — the security-first package manager for AI agent skills.

Search, download, read, and audit skills from the Tank registry. Designed for agent frameworks, notebook workflows, and any Python tool that wants to consume AI skills with provenance and integrity guarantees.

Install

pip install tank-sdk

For faster integrity verification, install the native extra:

pip install "tank-sdk[native]"

This installs tank-core — pre-built Rust wheels for Linux x86_64/aarch64, macOS x86_64/arm64, and Windows x86_64 (Python 3.11+). On unsupported platforms, pip will either build from source (requires a Rust toolchain) or fail. If you don't want the native dep, install the plain tank-sdk — every feature remains available via the pure-Python fallback.

Quick start

from tankpkg import TankClient

with TankClient() as client:
    results = client.search("nextjs")
    for skill in results.get("skills", []):
        print(skill["name"], skill["description"])

    skill = client.read_skill("@tank/nextjs")
    print(skill.content)

Authentication

The SDK reads ~/.tank/config.json (managed by the tank CLI) or the TANK_TOKEN environment variable. Login with:

tank login

Or pass a token explicitly:

TankClient(token="your-token")

Self-hosted registries

TankClient(registry_url="https://tank.your-company.com")

Or set TANK_REGISTRY_URL.

API

• search(query, *, page, limit) — search the registry
• info(name) — skill metadata
• versions(name) — list available versions
• version_detail(name, version) — full version record including scan_verdict, audit_score, integrity (SHA-512)
• download(name, version, *, dest) — download and verify tarball
• read_skill(name, version=None) — SKILL.md + references + scripts inline
• list_files(name, version=None) — file listing within a version
• read_file(name, version, path) — read a single file
• audit(name, version=None) — security scan verdict for latest or pinned version
• permissions(name, version=None) — resolved permission budget
• whoami() — authenticated user info
• star(name) / unstar(name) / get_star_count(name)

All methods raise typed exceptions: TankAuthError, TankNotFoundError, TankPermissionError, TankNetworkError, TankIntegrityError, TankConflictError.

Native acceleration

tank-sdk works fully in pure Python. Installing tank-sdk[native] pulls tank-core — Rust bindings that are wired in where it matters most today: SHA-512 integrity verification on TankClient.download(). The Rust core also exposes tarball extraction, semver resolution, and permission checks as primitives that are used by the Tank CLI and available for direct import as tankpkg_core.

Check whether native acceleration is active:

from tankpkg import has_native
print(has_native())  # True if tank-core is installed and loaded

When native acceleration is unavailable, tank-sdk falls back to hashlib.sha512 for integrity verification — same security guarantees, pure Python.
