The postpeg Agent Skill
The postpeg Agent Skill teaches a coding agent every endpoint, each network’s rules, errors and retries, so the code it writes against the API works first time.
What it teaches your agent
An Agent Skill is a folder of instructions a coding agent such as Claude Code loads when a task needs it. The postpeg skill covers:
- Every endpoint, with the exact request and response fields
- Each network’s rules: text limits, media, required options
- Publishing flow: check, publish or schedule, then follow each account’s status
- Errors by
code, what to retry, rate limits andIdempotency-Key - When to ask before acting: publishing, replying and sending are public
The TikTok loop, in order
The skill walks an agent through TikTok growth the way it should run: watch a niche, rank its videos by outlier_score (views ÷ the creator’s median views) rather than raw views, break the best one down, then post the user’s version with inspired_by so it is benchmarked against the niche at 24 hours and 7 days. It tells the agent to borrow a video’s structure, its hook type and format, never its words.
Publishing safely
A post can’t be taken back from the API, so the skill has the agent follow four steps every time: check the post against every network’s rules without publishing; show the user the exact text, media, accounts and time and wait for a yes; send once with an Idempotency-Key, so a retry after a timeout can’t publish twice; then follow each account’s status and report its link or error. Replies to comments and DMs get the same confirmation.
The skill is written and lives in the postpeg repository; there’s no public install link yet. Until then, point your agent at llms-full.txt (the whole docs in one file), or connect the MCP server, which works today.
Questions
- How do I install it?
- There’s no public install link yet. The skill is written and will be published with an install command; this page will have it the day it ships.
- Skill or MCP?
- Use the skill when a coding agent writes code that calls the API; use MCP when an assistant should act for you. The MCP server works today.

The 7-day trial has every feature and 3 connected accounts, with no card. It also posts to Instagram, YouTube, LinkedIn and more through your own Zernio account (its first 2 accounts are free). On TikTok, postpeg also shows what’s working in your niche: TikTok growth.
