The Answer Computer — reasoning tools for brainstorming, planning, architecture design, and deep thinking
Strategic CTO advisor grounded in the CTO canon (Larson, Fournier, Majors, DHH, Fowler, Team Topologies, DORA, Cagan) and AI-era realities. Use when facing leadership, strategy, organizational, or stakeholder challenges — not code-level problems. Applies frameworks situationally, challenges framing before solving, produces concrete artifacts.
Infrastructure code review for Terraform/OpenTofu, Helm charts, Kubernetes manifests, Dockerfiles, and CI/CD pipelines. Runs validation pipelines and checks security contexts, resource limits, and deployment safety. Use when reviewing infrastructure changes.
Detective agent that follows evidence trails to find root causes, bugs, and hidden problems. Uses Sherlock (deduction), Poirot (psychology/intent), and Columbo (what's missing) lenses. Works on code, performance, architecture, data, and systems.
Performance-focused code review analyzing N+1 queries, algorithmic complexity, memory usage, scaling projections, and SLO compliance. Use when reviewing changes to hot paths, database queries, or performance-critical code.
Python-specialized code review with focus on type safety, async correctness, Pydantic validation, SQLAlchemy session handling, and FastAPI patterns. Use when reviewing PRs or files that are predominantly Python code (.py files).
Turn brainstorm decisions into user stories, architecture doc, and ADRs. Use after brainstorming to define WHAT to build and HOW it fits together. Standalone or pipeline-aware via env vars. Triggers: architect, stories, architecture, design, ADR, define stories, write stories.
Deep architectural review of a platform or product — cross-references code against claims, maps failure modes, evaluates scaling bottlenecks, and produces a decision-grade handoff document with ADRs. Use when: reviewing an existing system for scaling readiness, performing a CTO handoff, evaluating platform architecture for enterprise readiness, or auditing a codebase before a major migration. Triggers: architecture review, scaling review, platform review, CTO handoff, system audit, scaling analysis, architecture assessment, production readiness.
Collaborative discovery before planning. Explore the problem space, evaluate approaches, surface past work, and produce a structured brainstorm document. Triggers: brainstorm, explore, discovery, ideate, think through, what should we build, explore approaches.
Meta-skill that generates and refines SKILL.md files using the 12 prompting techniques as a quality checklist. The skill that writes skills. Triggers: craft skill, create skill, generate skill, write skill, skill template, meta prompt, improve skill, refine skill.
Strategic CTO advisor with structured sub-commands. Helps technical leaders navigate architecture decisions, organizational design, stakeholder communication, and AI-era challenges. Each sub-command applies a specific framework and produces a concrete artifact. Triggers: cto, pivot cost, hire case, decision map, tech strategy, team health, board prep, ai audit.

32 skills for AI coding agents. Five plugins. Works with Claude Code, Codex, OpenCode, Pi, and any tool supporting the agentskills.io standard. Named after The Hitchhiker's Guide to the Galaxy because the universe is absurd and your tools should at least have personality.
/plugin marketplace add ondrej-svec/heart-of-gold-toolkit
/plugin install deep-thought@heart-of-gold-toolkit
bunx @heart-of-gold/toolkit install --to codex
The Codex target also applies Codex-specific wording transforms for flagship shared skills so interactive flows like brainstorm and plan more strongly encourage Codex's structured user-input UI instead of falling back to plain text when richer selection UX is available. It also rewrites slash-command references in installed skill text — both plain (/plan, /work) and plugin-prefixed (/deep-thought:review, /marvin:compound) — to Codex-style $... skill invocations.
bunx @heart-of-gold/toolkit install --to opencode
# Option A: install the package directly in Pi to get skills + pi-native extensions
pi install npm:@heart-of-gold/toolkit
# Option B: install shared skills only into Pi's native skill directory
bunx @heart-of-gold/toolkit install --to pi
Important: choose one Pi install path or the other.
Do not use both the Pi package install and install --to pi at the same time, or Pi will report duplicate skill collisions on reload.
The CLI now refuses install --to pi when your Pi settings already reference @heart-of-gold/toolkit as a package. If you intentionally want both paths for debugging, rerun with --force.
Pi also discovers skills from the shared ~/.agents/skills/ location, so installs done with the OpenCode target are usable from Pi too.
When installed as a Pi package, Heart of Gold exposes Pi-native extension commands for the flagship workflows:
/deep-thought-brainstorm — start a brainstorm (collaborative discovery)/deep-thought-plan — start planning (research and produce a plan document)/deep-thought-architect — turn brainstorm decisions into stories and architecture docs/share-html — publish an HTML file or static site directory through the portable share-html skill/share-server-setup — set up or adopt the local share server through the portable share-server-setup skill/share-server-control — control the local share server lifecycle through the portable share-server-control skill/marvin-work — start executing a plan (with always-on safety guardrails)Pi package installs also include a Pi-only guided workflow enhancer for supported Heart of Gold skills. For brainstorm, plan, and architect, when the assistant asks a high-confidence structured question, Pi can upgrade it into a custom interactive TUI and feed the answer back into the same workflow. Shared skills remain plain-text portable in every other harness.
For extension debugging, Pi also exposes /deep-thought-guided-debug to toggle notices explaining when a guided prompt was extracted, skipped, dismissed, or answered.
The skills themselves enforce their own boundaries (read-only for brainstorm/plan, safe commands for work) via allowed-tools and prompt constraints — no manual mode switching needed.
The work extension also provides always-on guardrails that protect .env, .git/, and node_modules/ from edits, block git add . and destructive rm, and require confirmation for git push / npm publish.

Some skills in this repository can, when configured by the user, interact with personal services and local tooling such as:
Treat skills and helper scripts as executable automation, not passive text. Review their contents before installing them, especially for plugins like Guide and Babel Fish that can access personal data or third-party services.
Ten ways to think clearly about hard problems.
Brainstorm before you plan. Plan before you build. Investigate when something breaks. Review when it ships. Map where it could go when you can't see the futures yet. And when the stakes are high, simulate an expert panel that argues with itself until the right answer falls out.
