What it does

Instantly Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Install pinned official Instantly SDK or CLI tooling and verify a least-privilege API v2 key. Use when bootstrapping an HTTP, SDK, CLI, or MCP integration. Trigger with "install the Instantly SDK", "configure Instantly authentication", or "set up the Instantly CLI".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live verification requires network access and an approved Instantly workspace and API v2 key

It sits in Backend & APIs, covering MCP servers. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Bootstrapping an HTTP
  • MCP integration
  • With install the Instantly SDK
  • Configure Instantly authentication

Example prompts

  • “install the Instantly SDK”
  • “configure Instantly authentication”
  • “set up the Instantly CLI”
  • “/instantly-install-auth”

Requirements

  • Node.js
  • A credential in INSTANTLY_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code; live verification requires network access and an approved Instantly workspace and API v2 key
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inspect the repository runtime, package manager, lockfile, and existing Instantly client.
  2. Choose HTTP, SDK, or CLI deliberately and verify current first-party installation guidance.
  3. Pin a compatible version; use the SDK beta tag only while the first-party docs require it.
  4. Create a key with only the exact endpoint scopes and store it in an approved secret manager.
  5. Verify with one bounded read-only request and distinguish 401 from 403.
  6. Record versions, workspace identity, scopes, evidence, rotation owner, and rollback.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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.instantly.ai

    Also links to:

    • developer.instantly.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • INSTANTLY_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; live verification requires network access and an approved Instantly workspace and API v2 key

    From compatibility in the SKILL.md frontmatter.

Context cost

Instantly Install Auth loads about 1.1k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 481 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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.

Install and Authenticate Instantly Tooling

Overview

Establish a reproducible server-side client without leaking a key or granting unnecessary scopes. Record assumptions, evidence, approval state, and rollback ownership so another operator can reproduce the result.

Prerequisites

  • The target repository, Instantly workspace, environment, and accountable owner
  • Current security, privacy, compliance, capacity, and change-control requirements
  • An approved API v2 key only when a bounded live verification is necessary

Tool Discipline

Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current first-party Instantly documentation and package metadata. Use Write or Edit only when implementation was requested and exact target files are known; never write credentials, lead data, email content, or unrestricted environment output.

Current Contract

  • The official TypeScript SDK is @instantlyai/sdk beta and requires Node.js 22 or later.
  • The official CLI is @instantlyai/cli and supports INSTANTLY_API_KEY for non-interactive use.
  • API v2 keys are displayed once and are not compatible with API v1.

Authentication

Use an API v2 key as Authorization: Bearer <key> against https://api.instantly.ai/api/v2. Grant only the endpoint-specific scopes needed, inject the key from an approved server-side secret manager, and never print, persist, commit, or place it in a URL. Treat key creation, rotation, revocation, member changes, workspace delegation, and production access as owner-approved actions.

Instructions

  1. Inspect the repository runtime, package manager, lockfile, and existing Instantly client.
  2. Choose HTTP, SDK, or CLI deliberately and verify current first-party installation guidance.
  3. Pin a compatible version; use the SDK beta tag only while the first-party docs require it.
  4. Create a key with only the exact endpoint scopes and store it in an approved secret manager.
  5. Verify with one bounded read-only request and distinguish 401 from 403.
  6. Record versions, workspace identity, scopes, evidence, rotation owner, and rollback.

Approval Boundaries

Do not create, rotate, reveal, or revoke keys; invite or remove members; delegate across workspaces; connect sending accounts; create or activate campaigns; import or delete leads; change suppression or retention; register, patch, resume, or delete webhooks; alter plans or paid capacity; transmit diagnostics; or perform another production mutation without explicit approval from the accountable owner. Keep diagnosis read-only unless implementation was requested.

Output

Return the workspace-safe scope, files and contracts inspected, exact API v2 routes and required scopes, evidence collected, validation result, sensitive fields redacted, remaining risk, accountable owner, approval state, and rollback or next action.

Error Handling

ConditionResponse
401Stop and verify that the bearer key exists, is current, and was not revoked.
403Stop and compare the operation with its exact required scope; do not broaden to all:all by default.
429Coordinate the workspace-wide budget, honor endpoint overrides, and bound retries.
Schema or tenant mismatchFail closed, preserve redacted evidence, and do not retry a mutation.

Examples

Use a compact handoff that makes scope, mutation authority, and evidence reviewable.

Input:

text
client=sdk; runtime=node22; scopes=campaigns:read

Expected handoff:

text
package=@instantlyai/sdk; auth=pass; key=redacted
