- 132 > "📐 Technical mode selected — using Docling for structure-aware extraction (tables, code blocks, formulas preserved as markdown). This takes ~1.5s per page, so expect a few minutes for longer sources. Starting now…"
+ 132 > "📐 Technical mode selected — PDFs attempt Docling for layout-aware extraction. EPUBs and other formats use their existing text extractors; code, tables, and formulas may lose structure. Check each source's `extraction_method` and `fallback_reason` in metadata.json for the actual extraction path."
- 463 Read the corresponding section of the extracted `full_text.txt` (use character offsets or grep for chapter headings).
+ 463 Read the corresponding section of the extracted `full_text.txt` using top-level `chapter_ranges` from `metadata.json` when present (`start_line`/`end_line` are 1-based inclusive, for `sed`/`Read`); otherwise grep for chapter headings. (`sources[].chapter_ranges` use the same fields but line numbers in that source's text only, not the consolidated `full_text.txt`.)
+ 613 - Full text: `<output_text from metadata.json>` — grep it for depth the chapter files omit (local extraction, not shipped)

How it works

book-to-skill

When your agent uses it

Converts books and documents (PDF, EPUB, DOCX, HTML, Markdown, plain text, RTF, MOBI/AZW with Calibre) into structured agent skills, extracting frameworks, mental models, principles, techniques, and anti-patterns. Use when the user wants to study a document through GitHub Copilot CLI, Amp, Claude Code, Hermes Agent, OpenCode, or OpenClaw, apply an author's frameworks while working, or build a reusable knowledge base from a file.

The playbook

Philosophy
Modes of Operation
Skill Locations
Step 0 — Out-of-scope check
Step 1 — Validate input
Step 1.5 — Identify content type
Step 2 — Extract text from the source documents
Step 2.5 — Pre-flight cost estimate
Step 2.6 — REPL-style access for large books (> 50k tokens)
Step 3 — Analyze book structure
Step 4 — Ask purpose (Full Conversion only)
Step 5 — Determine skill name
Step 6 — Create skill directory structure
Step 7 — Generate chapter summaries
Reference Tables *(technical books only — omit if BOOK_TYPE=text)*
Worked Example *(DEPTH=study only — omit for DEPTH=reference)*
Key Takeaways

Step 9.5 — Scan the generated skill
Step 10 — Cleanup and report
Step 11 — Publish the generated skill to GitHub (optional)

Cross-agent notes (informational; ignored by host agents):
  - Compatible skill roots: GitHub Copilot CLI (~/.copilot/skills, ~/.agents/skills,
    .github/skills, .claude/skills, .agents/skills), Amp (.agents/skills,
    ~/.config/agents/skills, ~/.config/amp/skills), Claude Code (~/.claude/skills),
    Hermes Agent ($HERMES_HOME/skills, .hermes/skills, .agents/skills),
    OpenClaw (${OPENCLAW_STATE_DIR:-~/.openclaw}/skills, .agents/skills, skills/;
    ~/.agents/skills only with the default state).
    OpenCode (~/.config/opencode/skills, ~/.claude/skills, .opencode/skills,
    ~/.agents/skills, .agents/skills).
  - `allowed-tools` is intentionally omitted to stay agent-neutral: Copilot CLI uses
    `shell`/MCP-server names, Claude uses `Bash`/`Read`/`Write`/`Glob`/`Grep`, Amp
    adds `shell_command`. The skill needs shell (to run extract.py) and file
    read/write — each host will prompt for those on first use.

**One command, any host** — the [`skills` CLI](https://skills.sh) resolves the repo, detects the root `SKILL.md`, and installs the complete skill (including `scripts/extract.py` and `tools/`) into the skills folder of every host you select:
