DevOps workflows for Playwright - CI failure analysis, workflow debugging, and release operations.
Best practices for Marketo developed by Etumos
Free sample skill — installs with one command, no API key. Included so anyone (human or AI agent) can try the bkstr install flow and see the SKILL.md layout and bundle shape before purchasing a paid title.
Score an action-plan against a 5-dimension rubric (LLM-judge, Bedrock Sonnet 4.5) and exercise its parallel-execution orchestrator against deterministic mocked sub-agents. Produces a scorecard JSON for archival and a markdown report for human consumption. Use when iterating on the action-plan skill, tuning the rubric, or qualifying a new book for action-plan.
Convert any book (markdown content) into a structured action plan and execute the plan via parallel sub-agents. Use when the user wants to operationalize a book — turn its ideas into concrete, executable steps that run in parallel. Works on any book content: passed inline or fetched from bkstr.tmrwgroup.ai by slug.
A prescriptive, chapter-by-chapter guide to operating well as a senior engineer who ships. Eight chapters covering foundations, ownership, leverage, communication, debugging, decisions, learning, and sustainability. Designed to be consumed by humans AND by the action-plan skill (which turns each chapter into executable action items).
Use this skill to create, convert, or improve reference books for the agent bookstore — structured knowledge documents optimized for LLM agent consumption. Trigger whenever the user mentions "book", "reference doc", "context book", "knowledge base entry", "agent manual", or asks to package domain knowledge, technical specs, procedures, or policies into a format agents can ingest. Also trigger when converting existing human-readable docs (PDFs, wikis, READMEs, vendor docs, standards) into agent-optimized format. Applies to any token size from 1K quick-reference cards to 1M+ multi-volume technical manuals.
A self-contained execution reference for autonomous AI agents operating under formal quality controls. Adapted from ASME NQA-1 nuclear quality assurance standards (10 CFR 50 Appendix B) for AI agent workflows, this 15-chapter manual covers criticality classification, work decomposition, assumption documentation, design control, supply chain validation, independent verification, test control, nonconformance handling, revision control, and audit programs. Each chapter is scoped so an agent loading only the relevant chapter can complete the corresponding workflow. ~65,000 tokens; includes 5 appendices and a glossary. Use when you need agents that can prove their work — not just produce outputs, but produce outputs with traceable quality controls and audit trails.
Understand why developers leave, identify at-risk users before they churn, and win back those who've already left. No guilt trips or desperate discounts — just honest understanding and genuine value.
A Turkish-language operational guide to Docker and Docker Compose patterns — local-dev setups, networking modes, volume strategies, container security, and common anti-patterns.
A playbook for triaging Svelte compiler diagnostic-parity bugs — isolating the first owning failure, capturing it as a failing diagnostic test, and routing the follow-up to the right spec.
Repo-internal runbook for dispatching and auditing a TDD orchestrator subagent during vitest-agent dogfood sessions. Includes chain modes, handoff continuation, verification steps, and a catalog of common subagent failure patterns. Specific to the vitest-agent repo; not a general resource.
A diagnostic playbook for OpenClaw node-pairing failures across Android, iOS, and macOS — topology-first triage, canonical checks, root-cause map, and fast heuristics for QR/setup-code, route, and auth issues.
A short reference for the gifgrep CLI/TUI tool — searching Tenor and Giphy, browsing results in a terminal, downloading GIFs, and extracting stills or contact sheets.
