使用说明 (SKILL.md)
Gamma.app — Presentations & Documents API
Create presentations, documents, social posts, and web pages programmatically via the Gamma API.
Homepage: https://gamma.app
API Docs: https://developers.gamma.app/docs/getting-started
Runtime dependencies: curl, python3 (for JSON building/parsing)
Setup
Set the environment variable before using:
export GAMMA_API_KEY="sk-gamma-xxxxx" # Get from https://gamma.app/settings
The script only makes network calls to https://public-api.gamma.app/v1.0. Your API key and inputText content are sent to Gamma's servers.
Quick Start
Generate a presentation
bash scripts/gamma.sh generate "AI trends in 2026 for business leaders" \
--format presentation --num-cards 10 --export pdf --wait
Generate a document
bash scripts/gamma.sh generate "Quarterly marketing report Q1 2026" \
--format document --text-mode generate --amount detailed \
--tone "professional" --audience "executive team" --export pdf --wait
Create from template
bash scripts/gamma.sh template "g_abcdef123" "Update this pitch deck for Twist Broadband client" \
--export pdf --wait
Check status manually
bash scripts/gamma.sh status "generationId123"
List themes and folders
bash scripts/gamma.sh themes
bash scripts/gamma.sh themes "dark"
bash scripts/gamma.sh folders

Workflow
- Generate — POST creates the gamma, returns a
generationId - Poll — Use
--waitor manually checkstatusuntilcompleted - Result — Completed response includes
gammaUrl(live link) and export download URL if requested - Credits — Response shows
credits.deductedandcredits.remaining
Input Tips
- Short prompts work ("AI trends 2026") but detailed structured text produces better results
- Insert image URLs directly in inputText where you want them placed
- Use
\ ---\in inputText to force card breaks (set--card-split inputTextBreaks) - To use only your images (no AI-generated ones), set
--image-source noImages - JSON-escape special characters in inputText
Credit Costs
- Cards: 1-5 credits each
- AI images: 2 credits (basic) to 125 credits (ultra) per image
- Example: 10-card deck with basic AI images ≈ 20-60 credits

安全使用建议
This skill is coherent and appears to do what it claims: call Gamma.app's public API to create presentations/documents. Before installing, consider: (1) Only provide a GAMMA_API_KEY you trust — use a dedicated account or limited key if possible. (2) Never include secrets, credentials, or confidential content in prompts/inputs, because the script sends inputText to Gamma's servers. (3) Verify the publisher/source (autosolutionsai-didac) if you require provenance; the registry source is unknown. (4) Inspect scripts/gamma.sh yourself (it's plain shell + python) and run it in an environment you control. (5) Review Gamma's privacy/security policy for how they store/persist uploaded content and exported files (export links expire but content may be retained).
功能分析
Type: OpenClaw Skill
Name: gamma-app-api
Version: 1.0.1
The skill contains a significant security vulnerability in `scripts/gamma.sh` where user-provided input (e.g., `--instructions` or the main input text) is directly interpolated into a `python3 -c` command string. This pattern allows for arbitrary Python code execution (RCE) if a user provides input designed to break out of the Python string literals. While this appears to be a poorly implemented JSON generator rather than intentional malware, the risk of exploitation is high. All network activity is correctly restricted to the official `public-api.gamma.app` endpoint.
能力评估
Purpose & Capability
Name/description match the implementation: the script and docs call https://public-api.gamma.app/v1.0 and require a GAMMA_API_KEY, plus curl/python3 for JSON and HTTP — all expected for a service API wrapper.
Instruction Scope
SKILL.md and scripts/gamma.sh only perform API calls to Gamma and local JSON construction; they do not read unrelated files or system credentials. Important: the skill sends your inputText (up to very large sizes) and the GAMMA_API_KEY to Gamma's servers, so prompts must not contain secrets or private data you don't want transmitted.
Install Mechanism
No install spec (instruction-only with a bundled script). Nothing is downloaded from external URLs or extracted; the included shell script is plain text and self-contained.
Credentials
Only a single credential (GAMMA_API_KEY) is required, which is proportionate to the API usage. Treat the key as a secret and consider using a dedicated/minimally-scoped key or account.
Persistence & Privilege
The skill is not always-enabled and is user-invocable. Autonomous invocation is allowed (platform default), which is normal; the skill does not request persistent system-level privileges or modify other skills.
如何使用
- 确保已安装 OpenClaw（本地或 Docker 部署）
- 在对话框中输入安装命令：
/install gamma-app-api - 安装完成后，直接呼叫该 Skill 的名称或使用
/gamma-app-api触发 - 根据 Skill 的参数说明提供必要输入，即可获得结构化输出
