Description
Generate AI-powered presentations, documents, and social posts using SkillBoss API Hub. Use when user asks to create a presentation, pitch deck, slide deck,...
Usage Guidance
Before installing: (1) Verify the correct API hostname with the skill author or official docs — SKILL.md documents api.skillbossai.com but the script sends requests to api.heybossai.com; this mismatch should be explained or corrected. (2) Confirm you trust the target domain (heybossai.com) and that SKILLBOSS_API_KEY is intended for use there. (3) Ensure required binaries (curl, jq) are available and consider reviewing the script locally to verify it only sends intended content and does not exfiltrate extra data. (4) Prefer running the skill in a sandbox or with a limited/test API key first, and compare responses/URLs (e.g., gamma.app export links) to expected provider behavior. If the author can confirm the correct API endpoint and why domains differ (or update the script to use the documented endpoint), the concern would be resolved; otherwise treat this as potentially unsafe.
Capability Analysis
Type: OpenClaw Skill
Name: toby-gamma
Version: 1.0.0
The skill bundle provides a legitimate interface for generating presentations via the SkillBoss API Hub. The shell script `scripts/gamma.sh` is well-structured, using `jq` to safely construct JSON payloads and prevent injection vulnerabilities. While there is a minor discrepancy between the API domains mentioned in the documentation (`api.skillbossai.com`) and the script (`api.heybossai.com`), the code logic is transparent, lacks obfuscation, and shows no signs of data exfiltration or malicious intent.

Capability Assessment
Purpose & Capability
The skill claims to use SkillBoss (api.skillbossai.com) and to generate Gamma URLs, which aligns with requesting SKILLBOSS_API_KEY. However, the included script uses API_BASE="https://api.heybossai.com/v1" (a different domain). The source/homepage are unknown, making the domain mismatch unexplained and suspicious.
Instruction Scope
SKILL.md instructs only to call the SkillBoss pilot endpoint and set SKILLBOSS_API_KEY, which is scoped correctly. The actual shell script does only API calls and JSON construction (no broad file or env harvesting), but it directs traffic to an unexpected endpoint (heybossai.com) rather than the documented skillbossai.com, creating a potential redirection/exfiltration risk.
Install Mechanism
There is no install spec (instruction-only), which is lower risk. However, the package includes a runnable script. The script relies on external binaries (curl and jq) but the skill metadata declares no required binaries — a mismatch that can cause runtime failures or hide implicit dependencies.
Credentials
The skill requires a single environment variable, SKILLBOSS_API_KEY, and the script uses that variable as a Bearer token for the API — this is proportionate to the stated purpose.
Persistence & Privilege
The skill does not request always:true, does not modify other skills, and does not persist credentials locally. It runs only when invoked, which is appropriate for this type of integration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install toby-gamma - After installation, invoke the skill by name or use
/toby-gamma - Provide required inputs per the skill's parameter spec and get structured output
