slidesync

A command-line tool that synchronizes Slidev Markdown presentations with Google Slides. Slidev is a way to write slide decks in Markdown, and the sync keeps Google Slides content editable instead of turning it into images.

In plain words
What is it for?
Use it to push a `.slidev.md` deck to Google Slides, pull an existing deck back into Markdown, or check that a round trip preserves the deck.
Why use it?
It removes the need to manually copy changes between a version-controlled Markdown deck and its Google Slides version.

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

slidesync 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

slidesync

Sync a Slidev markdown deck to/from Google Slides, building native Slides objects (title/body/bullets/tables/positioned images, brand-styled text boxes) — so the result stays editable, not a flat image. pull reconstructs the markdown from those native objects; roundtrip proves the loop is stable.

Packaged at github.com/DJRHails/slidesync (PyPI: slidesync). Run with uvx slidesync — no install needed.

Auth (no setup)

Borrowed from gog: OAuth client id/secret resolved cross-platform from ~/.config/gogcli/credentials.json (Linux/XDG), falling back to ~/Library/Application Support/gogcli/credentials.json (macOS) — and the keyring-password file at either location — mirroring gog's own resolution. Refresh token via gog auth tokens export. The stored token already carries slides+drive scopes. Requires the Slides API enabled on the gog Cloud project. The account defaults to gog's default account (override with --account or $SLIDESYNC_ACCOUNT).

Commands

Command Purpose
slidesync push <file.slidev.md>... [--deck ID] [--new "Title"] [--anchor SLIDE] [--prune] [--force] md -> Slides (rejected if it would discard live Slides edits; --force overrides)
slidesync pull <deckId> --out <file.md> [--all] Slides -> md (--all includes non-managed slides)
slidesync sync <file.slidev.md>... [--deck ID] [--prune] reconcile with the live deck: capture comment threads as <!-- @Author: ... -->, write live edits back into the markdown, push local changes; conflicts print three-way diffs and exit 1
slidesync comments <deckId> list comment threads as JSON (page anchor, author, content, replies)
slidesync roundtrip [--keep] self-test: push a sample, pull, assert identical
slidesync layouts <deckId> list a deck's theme layouts + placeholders
slidesync make-templates <deckId> inject legacy in-deck {{token}} template slides

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.
