What it does
Trello is an agent skill from zapier/connectors, published by the product's own GitHub organization. Agent-callable Trello tools — create and update cards, manage boards, lists, labels, checklists, and search. Use when the user mentions Trello or wants to create cards, move tasks, or manage boards, even if they do not name Trello explicitly.
Its SKILL.md is about 5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 118 other files, including scripts and reference files (for example `.claude-plugin/plugin.json`, `.mcp.json` and `CHANGELOG.md`). Compatibility notes: Run npm install --omit=dev in this directory, then node cli.js. The TypeScript source needs Node.js 22.18+; on older Node, run cli.js for build-it-yourself /…
It sits in Productivity & Automation. It works with Zapier. The repository describes itself as: Connect your agent to the apps you already use - with or without Zapier.
When your agent uses it
- The user mentions Trello
- Wants to create cards
- Even if they do not name Trello explicitly
Example prompts
- “/trello”
Requirements
- Node.js
- Compatibility (from SKILL.md): Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.
What it can do on your machine
Read from SKILL.md and the folder at commit e48d26f. 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
Ships 1 file in scripts/ (TypeScript and JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
npmnpxgit
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.trello.com
Also links to:
developer.atlassian.comagentskills.io
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.
Compatibility
Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.
From compatibility in the SKILL.md frontmatter.
Context cost
Trello loads about 5k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 1,496 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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Elastic-2.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,496 words (~4,953 tokens).
“Scripts for working with Trello against the Trello REST API (https://api.trello.com/1): create and move cards, manage boards and lists, labels and checklists, comments and attachments, member lookups, and search. 44 scripts across boards, lists, cards, labels, checklists, members, and search.”

How do I install Trello in Claude Code?
Run `npx skills add zapier/connectors --skill trello -a claude-code`. Or copy the skill folder (apps/trello in zapier/connectors) into .claude/skills/trello in your project. Claude Code loads it when a task matches its description.

Can I use Trello in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add zapier/connectors --skill trello -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/trello, .gemini/skills/trello, .github/skills/trello and .opencode/skills/trello in your project.
What does Trello need to run?
Going by SKILL.md and its folder, Trello needs TypeScript and JavaScript for the scripts in its folder and the command-line tools its instructions call (npm, npx and git). Our summary lists: Node.js. Compatibility (from SKILL.md): Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options..
Does Trello access the network?
SKILL.md names 3 domains. In commands or code: api.trello.com; the agent is likely to contact it when it follows the instructions. As links in the text: developer.atlassian.com and agentskills.io. This is read from the text; nothing was executed.
Is Trello safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Trello use?
Trello is published under the Elastic-2.0 licence (declared in SKILL.md).
How many tokens does Trello use?
About 5k tokens (SKILL.md is roughly 20k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8k tokens, read only when the agent opens those files.
