Usage Guidance

This skill appears to do what it says: it sends provided content to SkillBoss (api.heybossai.com) and returns a URL for the generated presentation. Before installing, consider: 1) Trust and scope of SKILLBOSS_API_KEY — only provide an API key with limited scope and rotate/revoke if compromised. 2) Privacy: any content you pass (including pasted files) is transmitted to the external service; do not send secrets or sensitive PII. 3) Missing dependency declaration: the script uses curl, jq, and bash — ensure those are present or examine/adjust the script before running. 4) Source reputation: the package owner and homepage are unknown; if you need stronger assurance, verify the SkillBoss domain and service privacy/terms, or run the script in an isolated environment. If any of these raise concerns, do not install or provide real API credentials until you can validate them.

Capability Assessment

ℹ Purpose & Capability

Name/description match the behavior: the script and SKILL.md call SkillBoss (api.heybossai.com) to generate presentations. The skill only requires SKILLBOSS_API_KEY, which is appropriate. Minor inconsistency: the manifest declares no required binaries, but the included script clearly depends on common CLI tools (curl, jq, bash).

✓ Instruction Scope

SKILL.md and scripts limit actions to building a JSON payload from provided content and sending it to SkillBoss /v1/pilot. The runtime instructions do not read unrelated system files or other environment variables. They do allow sending arbitrary content (user-supplied or file contents) to an external API — expected for this purpose but a privacy consideration.

ℹ Install Mechanism

No install spec is provided (instruction-only), which reduces install-time risk. However, the skill does include an executable script file; there is no declared install step or dependency declaration. This is low mechanistic risk but still requires trusting the included script content.

✓ Credentials

Only SKILLBOSS_API_KEY is required and used. That is proportionate to the stated functionality. The script does not request additional unrelated credentials or config paths.

✓ Persistence & Privilege

always is false and the skill does not attempt to modify other skills, system config, or persist credentials beyond reading SKILLBOSS_API_KEY at runtime. It does not request elevated privileges.

How to Use
