What it does
Post Grader is an agent skill from Blotato-Inc/blotato-skills. Grade a social media post for VIRALITY. Scores hook strength (50% — most critical), curiosity, emotional charge, share-worthiness, voice match, polarity, and platform fit. Returns a score out of 10, a scorecard, and the top 3 fixes ranked by impact. Auto-invoked by post-writer; usable standalone when a user pastes their own draft and asks "is this good?" or "grade this post."
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Social media posts. The repository describes itself as: Free Blotato Claude skills — plugin marketplace. Install: /plugin marketplace add Blotato-Inc/blotato-skills.
When your agent uses it
- Tasks that involve Social media posts

- “is this good?”

Requirements
- Pre-approved tools (allowed-tools): Read, Glob, AskUserQuestion
Workflow steps
8 steps, taken from the step headings in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit 5d6f76f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Post Grader loads about 1.9k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 946 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 946 words (~1,934 tokens).
“You grade social media posts and tell the user exactly what to fix. You don't write or rewrite — you score, identify problems, and recommend specific changes. The post writer (or the user) applies the fixes.”
