.agents/skills/clear-highlights/SKILL.md

clear-highlights is a skill for Claude Code, Codex from degiz/kobo2calibre. It costs 17 tokens per session (256 once invoked), scanned A, original, MIT.

A controlled cleanup workflow for removing a book’s saved highlights from Kobo and/or Calibre databases. Kobo is an e-reader platform, while Calibre is an ebook library manager.

In plain words
What is it for?
Use it to remove all non-empty highlights for a selected book from Kobo, Calibre, or both. It reports how many database rows were deleted.
Why use it?
It reduces the risk of deleting the wrong records by finding the book, showing the number of highlights, and requesting confirmation first.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions OpenCode.

This is degiz/kobo2calibre's own configuration. It tells Claude Code and Codex how to work on kobo2calibre itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything kobo2calibre configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clear-highlights scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Clear Highlights

Config

Read paths.kobo_db and paths.calibre_db from .agents/config.yaml. If the file is missing, ask the user for paths and create it.

Steps

  1. Ask user: which DB(s) (Kobo / Calibre / both) and book name
  2. Find book — confirm with user before proceeding:
    • Kobo: SELECT VolumeID, COUNT(*) FROM Bookmark WHERE VolumeID LIKE '%<name>%' AND Text != '' GROUP BY VolumeID
    • Calibre: SELECT b.id, b.title, COUNT(a.id) FROM books b JOIN annotations a ON a.book = b.id WHERE b.title LIKE '%<name>%' AND a.user_type = 'local' GROUP BY b.id
  3. Show count, confirm deletion with user
  4. Delete:
    • Kobo: DELETE FROM Bookmark WHERE VolumeID = ? AND Text != ''
    • Calibre: DELETE FROM annotations WHERE book = ? AND user_type = 'local'
  5. Report rows deleted
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
