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

pptx-mcp-server 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 4d 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.

Skill Instructions

This skill guides you to use the repository’s PPTX MCP Server tools correctly and efficiently.

When to use this skill

Use this skill when the user asks to:

  • Read PPTX slide content (text/images/metadata/visibility)
  • Read/update speaker notes (especially translation + short/original formatting)
  • Perform multi-slide notes workflows (batch read + batch update, atomic)
  • Replace text in slide content or speaker notes (literal or regex)
  • Hide/show slides, or other slide management tasks
  • Diagnose MCP server health

Guardrails (apply to all tasks)

  • Do not change slide content/layout unless explicitly requested.
  • Do not add new slides unless explicitly requested.
  • Keep empty notes empty (do not invent notes for slides with empty notes unless asked).
  • Prefer batch tools for multi-slide work to minimize round trips and keep updates atomic.
  • Prefer safe zip-based notes editing tools for speaker notes updates to preserve animations/transitions.

Vietnamese speaker notes style (when generating Vietnamese notes)

  • Address the audience as “anh/chị” (not “bạn”, not “quý vị”).
  • Use “chúng ta” for shared actions/goals.
  • Keep sentences short, speakable, and conversational.
  • Required structure (two versions):
- Short version:
[Brief summary - 30-50% of original length]

- Original:
[Full content with all details and explanations]

Best-practice workflows

Batch translate/summarize speaker notes (recommended)
  1. Read notes in batch with read_notes_batch (use slide_range for consecutive slides).
  2. Generate content with the LLM (translation + short summary), preserving empties.
  3. Apply atomically with process_notes_workflow (formats into short/original and updates in one atomic operation).
Targeted notes update (single slide)
  • Read context with read_notes (or read_notes_batch), then update with update_notes.
  • If updating many slides, use update_notes_batch.

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.
