What it does
Checkr is an agent skill from BankrBot/skills. Access real-time X/Twitter attention intelligence for Base chain tokens via the checkr API. Use when you need to know what is trending on CT, which tokens are spiking in social attention, get attention/price divergence signals, or fetch narrative summaries for specific Base tokens. Triggers: "what's trending on Base", "check attention for $TOKEN", "what's spiking right now", "social signal for X", any token research needing CT attention data. Payments via x402 — USDC on Base, no API key or account needed.
Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `catalog.json` and `references/endpoints.md`).
It works with x402, Circle USDC and X (Twitter). The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
When your agent uses it
- You need to know what is trending on CT
- Which tokens are spiking in social attention
- Get attention/price divergence signals
- Fetch narrative summaries for specific Base tokens
Example prompts
- “s trending on Base”
- “check attention for $TOKEN”
- “s spiking right now”
- “/checkr”
Requirements
- Python 3
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit dc47eed. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pipnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.checkr.social
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
Checkr loads about 941 tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 235 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.
