oh-my-agent is a harness for checking whether coding agents actually completed their work by verifying tests, required artifacts, independent reviews, and recorded decisions. It is used across multiple agent runtimes to make workflow results auditable instead of relying on an agent's own report. The catalogue add-ons provide parts of its skills, agents, hooks, MCP integrations, instructions, and plugins.
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.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00110 | $0.04402 |
| Opus 5 | $0.00055 | $0.02201 |
| Sonnet 5 | $0.00022 | $0.00880 |
| Haiku 4.5 | $0.00011 | $0.00440 |
Grade C, and why
oma-slide scanned grade C with 1 finding 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 today.
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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Slide Agent — Animation-Rich HTML Deck Generator
Scheduling
Goal
Generate distinctive, anti-"AI slop" HTML presentation decks authored at a fixed 1920×1080 stage,
validate geometry deterministically via the oma slide CLI, and deliver self-contained bundles
exportable to PDF, PNG, and PPTX.
Intent signature
- User asks to create a slide deck, presentation, keynote, or series of slides.
- User provides a topic, outline,
.pptxto import, or existing deck to enhance. - User mentions slide, deck, pptx, keynote, 슬라이드, 발표자료, プレゼン, 幻灯片, 演示文稿.
- User mentions Canva, canva export, canva import, 캔바, キャンバ.
- Another skill needs a visual output artifact (e.g., a research result delivered as a deck).
When to use
- Creating a new presentation from a topic or outline
- Enhancing or reformatting an existing deck
- Generating per-slide HTML with animations and design-doctrine aesthetics
- Exporting a deck to PDF, PNG, or image-backed PPTX after generation
- Applying a named style preset or bold template to a deck
- Exporting a generated deck to Canva as a presentation
- Importing a Canva design as input for enhancement
When NOT to use
- Plain document creation (no slides needed) → use oma-backend or direct output
- Image generation alone → use oma-image directly
- Brand/design-system definition → defer to oma-design
- Deterministic CLI ops (validate/bundle/export) without generation → call
oma slideCLI directly - Long-form scrolling code-change explainer document → use oma-explanation (deck is a fixed 1920×1080 stage)
Expected inputs
- Topic, title, or outline (text or markdown)
- Optional:
.pptxfile to import (oma slide import pptx) - Optional: user-provided images/video in
./assets/ - Optional: slide count, density preference (sparse/balanced/dense), target audience
- Optional: named style preset or
oma slide style get <slug>reference - Optional: Canva design ID or URL for import
- Optional: acknowledgement that exported PPTX and Canva uploads are raster-backed when editable text is not required

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.

oma-slide is a skill published in the GitHub repository first-fluke/oh-my-agent (1,278 stars, last pushed today), licensed MIT. It adds 110 tokens to every session and 4,402 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
