Domain experts publish their playbooks here — not as PDFs for humans, but as high-density, machine-first volumes your marketing-ops, QA, and DevOps agents fetch over a single API call. Measurably better work, per book.
Human books are optimized for the medium that reads them — cover, blurb, table of contents, long ramps into ideas, redundancy for retention. None of that helps a language model. bkstr publishes the same expertise as an agent reads it: dense, indexed, decision-shaped, token-efficient.
The shorthand — i bght bk frm bkstr — is the same idea you'd write longhand, with about half the context spent. That's what a well-edited agent-book delivers across an entire domain.
Sign up free. Read excerpts, lift scores, and the full table of contents before you buy.
One-time purchase per volume — $5 to $14. Stripe checkout.
Scope keys per agent, per book, per environment. Rotate without redeploy. A single GET returns the volume.
Per-book fetch logs, agent attribution, and the lift score we publish per title. Buy more shelves as you grow.
Pick a book or skill from the catalog and complete checkout.

Free books and skills install with no key. For paid items, create a key at /dashboard/api-keys and export it as $BKSTR_KEY.
One command — curl … | tar xz fetches the bundle and unpacks it straight into your agent's skills directory.
# Install docs-capture-sample-skill (free) — copy-paste, runs as-is on a fresh machine $ mkdir -p ~/.claude/skills && curl -sL https://bkstr.tmrwgroup.ai/api/install/docs-capture-sample-skill | tar xz -C ~/.claude/skills/
Prefer npm? npx -y @clawbot678/bkstr install docs-capture-sample-skill installs the same bundle with the bkstr CLI.
Paid items: prepend an export BKSTR_KEY=bks_… line and add -H "Authorization: Bearer $BKSTR_KEY" to the curl — full copy-paste command on the get-started guide.

Every volume on bkstr is run through the house style: chapter-level lift testing, token budgeting, decision-tree extraction, and a final pass with a human editor who's shipped the work.
Every volume is a one-time purchase between $5 and $14. Pay once, fetch as many times as your agents need. Updates within a major version are free — we email you when a new edition drops, and you decide whether to upgrade.
Checkout runs on Stripe's hosted page — we never touch your card data. Each volume produces one receipt; lifetime spend and Stripe payment IDs live in your billing dashboard.
