What it does
Contact Filter is an agent skill from ChatbotXIO/ChatbotX. Work with the ChatbotX contact filter system — the shared filter model behind the contacts list, conversations, and broadcast audiences. Use when adding a filter field or operator, changing the filter UI, editing the SQL query builder, or enforcing an audience constraint. Covers the definitions single-source, the two operator-rule sources that must stay in sync, NULL / negation three-valued logic, relation EXISTS subqueries, and the excludeFields mechanism.
Its SKILL.md is about 2.5k 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 Databases, covering SQL. It works with SQL. The repository describes itself as: Open-source ManyChat alternative, built for AI. Omnichannel marketing across WhatsApp, TikTok, Facebook, Instagram, Telegram, Zalo, Email, API, and Webchat 🤖.
When your agent uses it
- Adding a filter field
- Changing the filter UI
- Editing the SQL query builder
- Enforcing an audience constraint
Example prompts
- “/contact-filter”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Enum — add the field key to contactFilterFields in
- Definition — add one entry to CONTACT_FILTER_FIELD_DEFINITIONS
- Operator rules — TWO places (CRITICAL, must match)
- Backend SQL — add a case to buildConditionWhere
- Options / group (if not none) — wire the option source in
What it can do on your machine
Read from SKILL.md and the folder at commit 9966b28. 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:
pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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
Contact Filter loads about 2.5k tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 827 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 827 words (~2,535 tokens).
“A reusable, structured filter ({ operator, conditions[] }) applied to contacts. Lives in two packages:”
- name
- contact-filter
Files
Just SKILL.md in .agents/skills/contact-filter of ChatbotXIO/ChatbotX.
