Overview

The Every CLI ships with a skill called use-every — a set of instructions that teaches a coding agent (Claude Code, Codex, Cursor) how to drive the CLI well: parse the --json envelope, branch on exit codes, resolve IDs before acting, apply the right safety flags, and follow Every’s domain workflows (like converting an accepted proposal to an invoice, or never double-logging an activity that Every already tracks). Without the skill an agent can still use the CLI — the commands are self-describing via every docs and every tools describe. With the skill, it gets there in far fewer steps and avoids the common mistakes.

​
Bundled vs. installed

Installing the CLI does not automatically install the skill into your agent. The skill file ships inside the npm package, but it only becomes active once it’s placed in your agent’s skills directory. That step is deliberate and explicit — a package shouldn’t silently write into your project.
  • npm install -g @everyai/cli puts the every binary on your PATH and the skill file inside the package. Your agent doesn’t see it yet.
  • The skill becomes active once it lives in ./.claude/skills/use-every/ (Claude Code) or ./.agents/skills/use-every/ (Codex).

​
Install the skill

1

Run the install command

every skills install claude   # → ./.claude/skills/use-every/

every skills install codex    # → ./.agents/skills/use-every/
Both write into the current directory by default. Pass --dir <path> to install elsewhere.
2

Commit it to share

The skill is a plain file in your repo — commit it so everyone on the team (and their agents) gets the same behavior.
You don’t have to remember the command. After every login in an interactive terminal, the CLI detects Claude Code or Codex on your machine and offers to install the skill for you — just pick an option at the prompt.

​
As a plugin

You can also install it through your agent’s plugin system, which delivers the skill and points you at the CLI: 
/plugin marketplace add Every-AI-Inc/everyai-cli
/plugin install every@everyai-cli

# Add the marketplace from the everyai-cli repo, then install the "every" plugin.

​
What the skill teaches

  • The output contract — always --json, parse the envelope, branch on exit codes.
  • ID discipline — list or search first, act only with the exact ID returned; ask when a name is ambiguous.
  • Safety choreography — reads run free; add --yes only for a requested write; add --allow-destructive only for a requested send/delete/payment; confirm anything a client will see.
  • Every’s domain rules, the things a generic tool description can’t convey — for example:
    • Creating a proposal, invoice, or booking is auto-recorded on a matching deal, so it should never be double-logged.
    • Only issued or approved proposals convert to invoices, and conversion (not manual re-creation) preserves the link.
    • Invoice line items use per-unit prices; Every applies the business’s default tax automatically.
    • For “who owes me money”, filter by status and paginate to completion before totaling.
The result: an agent that behaves like it already knows how your business runs in Every.
