Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00122 | $0.06878 |
| Opus 5 | $0.00061 | $0.03439 |
| Sonnet 5 | $0.00024 | $0.01376 |
| Haiku 4.5 | $0.00012 | $0.00688 |
Grade A, and why
powerpoint-cli 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 479 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PowerPoint Automation with pptcli
Preconditions
- Windows host with Microsoft PowerPoint installed (2016+)
- Uses COM interop — does NOT work on macOS or Linux
- Requires
pptcli.exeon PATH (dotnet tool install --global Sbroenne.PowerPointMcp.CLI)
How pptcli Works — a Background Daemon, Not a Cold Start Per Command
Launching PowerPoint and tearing it down again can take 90-150 seconds. To avoid paying that
cost on every single CLI invocation, pptcli keeps one PowerPoint instance alive in a small
background daemon (pptcli service run), auto-started the first time you open or create a
session, and reused by every subsequent command that references the same session id — even
though each command is a separate OS process.
Workflow Checklist
| Step | Command | When |
|---|---|---|
| 1. Session | session create/open |
Always first |
| 2. Slides | slide add-blank |
If needed |
| 3. Edit content | See command reference below | Shapes, text, tables, charts, images, media, notes |
| 4. Save & close | session close --save |
Always last |
CRITICAL RULES (MUST FOLLOW)
Rule 1: NEVER Ask Clarifying Questions
Execute commands to discover the answer instead:
| DON'T ASK | DO THIS INSTEAD |
|---|---|
| "Which file should I use?" | pptcli session list |
| "How many slides does the deck have?" | pptcli slide get-count -s <id> |
| "How many shapes are on this slide?" | pptcli shape get-count -s <id> --slide-index N |
You have commands to answer your own questions. USE THEM.
Rule 2: Always End With a Text Summary
NEVER end your turn with only a command execution. After completing all operations, always provide a brief text message confirming what was done. Silent command-only responses are incomplete.
Rule 3: Session Lifecycle
Creating vs Opening Files:
# NEW file - use session create
pptcli session create C:\decks\demo.pptx # Creates file + returns session ID
# EXISTING file - use session open
pptcli session open C:\decks\demo.pptx # Opens file + returns session ID
What ships with it
18 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

powerpoint-cli is a skill published in the GitHub repository sbroenne/mcp-server-powerpoint (19 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 6,878 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
