Agent-callable Harvest tools — track time (log hours, start/stop timers), and manage the projects, clients, contacts, and tasks time is logged against, plus read invoices and account settings.

  • The user wants to log
  • SKILL.md covers When to use this, Setup, Scripts and Disambiguation & refusals, plus 3 more sections
  • Runs TypeScript and JavaScript scripts from its folder; calls npm, npx and git; reaches api.harvestapp.com

What it does

Harvest is an agent skill from zapier/connectors, published by the product's own GitHub organization. Agent-callable Harvest tools — track time (log hours, start/stop timers), and manage the projects, clients, contacts, and tasks time is logged against, plus read invoices and account settings. Use when the user wants to log or edit time, manage Harvest projects/clients/tasks, or check what was billed — even if they don't name Harvest explicitly.

Its SKILL.md is about 5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 86 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, covering Forms and invoices and Time tracking and reporting. 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 wants to log
  • Manage Harvest projects/clients/tasks
  • Check what was billed — even if they dont name Harvest explicitly

Example prompts

  • “/harvest”

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:

    • npm
    • npx
    • git

    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.harvestapp.com

    Also links to:

    • help.getharvest.com
    • agentskills.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

Harvest loads about 5k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 1,613 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

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 1,613 words (~5,024 tokens).

“Independent, unofficial connector for Harvest. Not affiliated with, endorsed by, or sponsored by Harvest. "Harvest" is a trademark of its owner, used only to identify the service this connector works with.”

How do I install Harvest in Claude Code?

Can I use Harvest 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 harvest -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/harvest, .gemini/skills/harvest, .github/skills/harvest and .opencode/skills/harvest in your project.

What does Harvest need to run?

Going by SKILL.md and its folder, Harvest 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 Harvest access the network?

SKILL.md names 3 domains. In commands or code: api.harvestapp.com; the agent is likely to contact it when it follows the instructions. As links in the text: help.getharvest.com and agentskills.io. This is read from the text; nothing was executed.

Is Harvest 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 Harvest use?

Harvest is published under the Elastic-2.0 licence (declared in SKILL.md).

How many tokens does Harvest 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 8.1k tokens, read only when the agent opens those files.
