Description
Schedule and manage social media posts across TikTok, Instagram, Facebook, X (Twitter), YouTube, LinkedIn, Threads, Bluesky, Pinterest, Telegram, and Google...
Usage Guidance
This skill appears to be what it claims: a PostFast API integration. Before installing, confirm you trust postfa.st and that the API key you provide has the minimum necessary privileges. Treat POSTFAST_API_KEY like a secret: store it in a secure secrets store (not a public repo), rotate it periodically, and avoid sharing the workspace key with untrusted agents. Be aware that the key can be used to publish, delete, or generate connect links for your workspace — if you need safer scope, ask PostFast whether scoped/limited keys or per-account tokens are available and prefer those. Also review PostFast rate limits and platform-specific posting limits (e.g., X API limits) to avoid accidental account restrictions. If you want higher assurance, validate the service by signing up at the listed homepage and checking your workspace dashboard and API key scopes before handing the key to the skill.
Capability Analysis
Type: OpenClaw Skill
Name: postfast
Version: 1.7.1
The PostFast skill bundle provides a comprehensive and legitimate interface for an AI agent to interact with the PostFast social media management SaaS (https://api.postfa.st). The documentation (SKILL.md and references/) and examples (examples/) detail standard API interactions, including account listing, multi-platform scheduling, and a secure 3-step media upload process using pre-signed S3 URLs. There is no evidence of malicious intent, data exfiltration, or unauthorized execution; all instructions are strictly aligned with the stated purpose of automating social media workflows.

Capability Assessment
Purpose & Capability
The skill claims to schedule/manage posts across many social platforms and only asks for a single POSTFAST_API_KEY and uses api.postfa.st / app.postfa.st endpoints; that is proportionate and expected for a SaaS API integration.
Instruction Scope
SKILL.md contains concrete curl examples and a 3-step signed-upload flow (get-signed-upload-urls → PUT to signed S3 URL → POST social-posts). It only references the declared env var (POSTFAST_API_KEY) and the documented PostFast endpoints; there are no instructions to read unrelated files, environment variables, or to send data to unknown endpoints.
Install Mechanism
This is an instruction-only skill with no install spec or downloads, so nothing is written to disk or fetched at install time — lowest install risk.
Credentials
Only POSTFAST_API_KEY is required and declared as the primary credential. That matches the documented API usage. Note: an API key typically grants workspace-level capabilities (scheduling, deleting, generating connect links) — the key's actual scope depends on PostFast's key model rather than the skill.
Persistence & Privilege
The skill is not 'always:true' and has no install hooks. disable-model-invocation is false (the platform default); the skill can be invoked autonomously by the agent, which is normal but means the agent could use the provided POSTFAST_API_KEY to act on your workspace while enabled.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install postfast - After installation, invoke the skill by name or use
/postfast - Provide required inputs per the skill's parameter spec and get structured output
