slidepoise

slidepoise is a skill for Codex from henryhyw/slidecraft. It costs 103 tokens per session (5,917 once invoked), scanned A, original, MIT.

A skill for creating one editable, information-rich PowerPoint slide. It combines design guidance with tools that generate, measure, and reconstruct slide elements.

In plain words
What is it for?
It helps plan a slide, choose or create visual assets, build it with PptxGenJS, measure pixels with OpenCV, fit text, and review the final result.
Why use it?
It gives the assistant a defined process for making and visually reviewing a slide instead of relying only on automated checks.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions subagents; mentions Codex.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/resolve_config.py --base /absolute/path/to/slidepoise-home/config.json --profiles-root /absolute/path/to/slidepoise-home/profiles --session sessi.

Good fit It helps plan a slide, choose or create visual assets, build it with PptxGenJS, measure pixels with OpenCV, fit text, and review the final result.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

slidepoise 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 9d ago.

The scan reads SKILL.md. This mod also ships 33 executable files (runtime/js/scene_to_pptx.mjs, runtime/scripts/audit_powerpoint_text.py, runtime/scripts/measure_visual_scene.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SlidePoise

Act as the host Agent for one information-bearing slide. Own interpretation, communication design, resource choice, image-generation orchestration, every visual judgement, semantic mapping, peer/alignment reasoning, reconstruction intent, review, and acceptance. Use scripts only to collect deterministic evidence or perform deterministic construction, including measurement, geometry, text fitting, file/library operations, asset-sheet construction, raster extraction, rendering, and objective contract facts. Scripts never issue an overall stage verdict.

Absolute authority rule

If answering a question requires looking at the slide, look at the slide and reason visually. Never replace that judgement with a score, confidence threshold, object count, whitespace metric, file-exists check, or heuristic pass/fail.

OpenCV is mandatory pixel evidence. The Agent says what an object is, which region it owns, and which measured geometry needs correction. Code executes explicit decisions without discovering visual peers or choosing alignments.

Read before working

At the start of every run:

  1. Resolve the SlidePoise CLI once. Use slidepoise when it is on PATH. After the one-line GitHub setup, use ~/.slidepoise/python/bin/slidepoise on macOS or Linux and %USERPROFILE%\.slidepoise\python\Scripts\slidepoise.exe on Windows. Respect SLIDEPOISE_HOME when it is set. Run doctor and profile show with that CLI to locate the framework home and selected external profile. Use the same resolved command for every later slidepoise example in this skill.
  2. Read the external framework config, selected profile, and its selected Library Sets. Profiles, visual references, icons, and components never live inside this skill. Read references/profile-authoring.md when the user wants to create, modify, understand, or curate a guidance profile or its persistent resources.
  3. Resolve current-session overrides with scripts/resolve_config.py, passing the framework config and profiles root.
  4. Read references/workflow.md.
  5. Read references/runtime-host.md for ChatGPT/Codex image-generation/tool adaptation.
  6. Read references/human-approval.md and enforce the three hard user gates.
  7. Read references/resource-library.md before resource selection.
  8. Before semantic mapping/reconstruction, read references/visual-reasoning.md, references/connectors.md, and references/reconstruction.md.
  9. For raster artwork, intrinsic lettering, texture, or overlapping text, read references/raster-composition.md. Read references/illustration-refinement.md before considering an optional raster edit.
  10. Read references/case-studies.md when preserving a reusable example or preparing project showcase material. Save exact image prompts and their inputs/outputs during the run so a later case study can use real evidence.
  11. Read references/multi-agent-review.md when the host exposes subagents. Use its bounded, read-only reviews at the configured checkpoints.
  12. Read references/user-language.md before authoring user-facing prose, slide copy, Panel summaries, activity messages, or approval questions.

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.
