Convert technical books, docs, and PDFs into a unified agent skill your AI coding assistant can reference in Claude Code, Copilot CLI, or Amp.
Key features
- Multi-Format Ingest: Accepts PDF, EPUB, DOCX, Markdown, HTML, RTF, and MOBI as source material.
- Folder & Multi-Source Support: Bundle a directory of mixed documents into one unified skill rather than one file per skill.
- Agent Skills Standard Output: Produces skills that conform to the Agent Skills Open Standard so any compliant agent can load them.
- Assistant Compatibility: Works with Claude Code, GitHub Copilot CLI, and Amp out of the box.
- Token-Efficient Retrieval: Reports 24×–51× fewer tokens than dumping the source text into context.
- MIT-Licensed CLI: Ships as an installable command-line tool with open-source license and GitHub releases.
Best for
- Personal Study Reference: Convert a technical book you're reading into a skill your coding agent can quiz you on or cite while you code.
- Domain-Knowledge Onboarding: Package a company's PDF handbook or spec collection so new-hire agents can answer questions without human bandwidth.
- Framework Documentation: Turn a language or framework's PDF/HTML docs into a locally referenceable skill for offline agent use.
- Research Collection: Bundle a folder of papers into one skill so an agent can cross-reference them during writing sessions.
- Legacy System Playbook: Ingest older manuals or runbooks (RTF, DOCX) so agents helping with maintenance have grounded answers.

Coding-agent skill that forces action-first, numbered answers — kills the 'Great question! Let me think...' preamble in Claude Code, Codex, and friends.
Key features
- Action-First Output Rule: Every response leads with the next concrete action instead of preamble.
- Numbered Multi-Step Tasks: Coding tasks come back as numbered lists capped at 5 items each.
- Preamble & Closer Suppression: Eliminates 'Great question!', 'Hope this helps', and other filler.
- Specific Time Estimates: Forces the agent to answer with minutes rather than vague 'a bit' phrasing.
- One-Command Install: /i-have-adhd in Claude Code, $i-have-adhd in Codex, or persistent activation via ~/.claude/.i-have-adhd.
- Auto-Update in Claude Code: Claude Code fetches the skill from GitHub and keeps it up to date — no local clone needed.
- Multi-Language Skill Docs: README available in English, Simplified Chinese, Japanese, Korean, Vietnamese, and Portuguese (BR).
- Fork-and-Tune: Copy skills/i-have-adhd/SKILL.md, edit the 10 rules to taste, restart the agent, and re-invoke.
Best for
- Reduce Preamble Fatigue: Developers who lose time scanning past 'Great question!' openings get straight-to-the-point agent output.
- ADHD-Friendly Workflow: Neurodivergent developers get responses formatted the way their attention can actually consume.
- Terminal-First Sessions: Users driving Claude Code or Codex from a terminal want short, numbered instructions rather than essays.
- Team Style Standard: Teams adopt the skill so every developer's coding agent responds in the same terse format.
- Custom Response Rules: Fork the SKILL.md and hand-tune the 10 rules to fit an internal engineering culture or accessibility need.
