Description
Post to X (Twitter) using the OpenTweet API. Create tweets, schedule posts, publish threads, upload media, run an evergreen queue, search inspiration tweets,...
Usage Guidance
This skill appears coherent with its purpose, but it can publish and schedule posts on your behalf — only provide an OPENTWEET_API_KEY you trust and that is scoped appropriately. If possible, test with a non-critical or throwaway X account first. Understand that the skill can publish immediately, schedule posts, enable auto-retweets, and access analytics for connected accounts; revoke the API key if you see unexpected activity. Verify OpenTweet's service and terms (https://opentweet.io) before granting access.
Capability Analysis
Type: OpenClaw Skill
Name: opentweet-x-poster
Version: 1.2.1
The skill bundle provides a legitimate interface for the OpenTweet API to manage X (Twitter) posts, including scheduling, media uploads, and analytics. The instructions in SKILL.md focus on functional API usage and include proactive safety guardrails, such as requiring user confirmation before publishing and preventing automated loops, with no evidence of malicious intent or data exfiltration.

Capability Assessment
Purpose & Capability
Name/description describe posting, scheduling, media uploads, threads, analytics and the skill only requires an OPENTWEET_API_KEY and documents REST calls to https://opentweet.io — this credential and the described endpoints are consistent with the claimed purpose.
Instruction Scope
SKILL.md contains explicit API requests (GET/POST/PUT) to OpenTweet endpoints, guidance to check subscription/limits, and instructions for uploads and scheduling. It does not instruct reading local files, unrelated environment variables, or sending data to non-OpenTweet endpoints. Note: the actions allowed (posting, scheduling, auto-retweeting, evergreen queues) are powerful and will publish to user accounts when used.
Install Mechanism
No install specification or code is bundled (instruction-only). No downloads or package installs are requested, so there is no install-time code risk.
Credentials
Only OPENTWEET_API_KEY is required and declared as the primary credential. That is proportionate for an API-based posting/scheduling skill; no unrelated secrets or system paths are requested.
Persistence & Privilege
always:false and default model invocation settings mean the skill is not force-included system-wide. It does not request modifying other skills or system configs. The skill will be able to act (post/schedule) using the provided API key per normal platform behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install opentweet-x-poster - After installation, invoke the skill by name or use
/opentweet-x-poster - Provide required inputs per the skill's parameter spec and get structured output
