Usage Guidance
This skill appears internally consistent, but before installing: 1) only provide a PostSyncer personal access token with the minimal scopes you need (e.g., avoid granting write if you only need read), 2) treat POSTSYNCER_API_TOKEN as sensitive — store and rotate it like any API secret, 3) confirm that the connected social accounts in the PostSyncer app are the intended accounts (deletes and posts are supported), 4) be aware the skill will make network calls to https://postsyncer.com and may import media from external URLs you provide, and 5) if you prefer stricter control, disable autonomous skill invocation or restrict the token to a sandbox workspace first to test behavior.
Capability Analysis
Type: OpenClaw Skill
Name: postsyncer
Version: 2.1.1
The PostSyncer Social Media Assistant is a legitimate skill bundle designed to interface with the PostSyncer API for social media management. It provides comprehensive documentation for REST and MCP interactions with postsyncer.com, requiring only the POSTSYNCER_API_TOKEN. No evidence of data exfiltration, malicious execution, or prompt injection was found; the instructions even include safety best practices such as confirming destructive actions with the user.
Capability Assessment
Purpose & Capability
Name/description (social media management via PostSyncer) align with the declared requirement (POSTSYNCER_API_TOKEN) and the SKILL.md, which documents REST endpoints for workspaces, accounts, media, posts, folders, labels, campaigns, and analytics.
Instruction Scope
SKILL.md confines actions to calling postsyncer.com/api/v1 endpoints and explicitly instructs using the POSTSYNCER_API_TOKEN from the environment. It does not instruct reading unrelated files, other environment variables, or sending data to third-party endpoints outside postsyncer.com (except for importing media from user-provided external URLs, which is documented).
Install Mechanism
No install spec or code files are included (instruction-only), so nothing is written to disk or downloaded. This is low risk and appropriate for an API-integration skill.
Credentials
Only a single credential is required: POSTSYNCER_API_TOKEN (declared as primaryEnv). That is proportional and expected for an API-based social-media assistant. No unrelated credentials or config paths are requested.
Persistence & Privilege
The skill is not always-enabled (always: false) and uses the platform default allowing autonomous invocation; this is normal. It does not request elevated system persistence or modification of other skills' configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install postsyncer - After installation, invoke the skill by name or use
/postsyncer - Provide required inputs per the skill's parameter spec and get structured output
