What it does

Instantly Core Workflow B is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze sending-account readiness, then connect and qualify Instantly accounts with OAuth, health checks, and controlled campaign assignment. Use when onboarding mailboxes or deciding which healthy accounts may join a campaign. Trigger with "connect Instantly sending accounts", "check Instantly mailbox health", or "assign accounts to a campaign".

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 OAuth and OpenID Connect. 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

  • Onboarding mailboxes
  • Deciding which healthy accounts may join a campaign
  • With connect Instantly sending accounts
  • Check Instantly mailbox health

Example prompts

  • “connect Instantly sending accounts”
  • “check Instantly mailbox health”
  • “assign accounts to a campaign”
  • “/instantly-core-workflow-b”

Requirements

  • 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. Confirm account ownership, provider, workspace, allowed domains, and change owner.
  2. Create a least-privilege OAuth session and give the authorization URL only to the account owner.
  3. Poll the session within its expiry window without logging tokens.
  4. Test account vitals and capture only non-sensitive status fields.
  5. Enable warmup or campaign assignment only after an explicit change approval.
  6. Poll background jobs and produce per-account success and failure evidence.

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 no API keys, tokens, secrets or passwords.

    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 Core Workflow B 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 94 tokens; SKILL.md has 464 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
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.

Instantly Sending Account Onboarding

Overview

Onboard Google or Microsoft sending accounts without exposing credentials or assigning unhealthy accounts to live campaigns. 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

  • Google and Microsoft connections use an OAuth session URL followed by status polling.
  • OAuth sessions expire after 10 minutes.
  • Warmup enablement may return a background job that must be polled.

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. Confirm account ownership, provider, workspace, allowed domains, and change owner.
  2. Create a least-privilege OAuth session and give the authorization URL only to the account owner.
  3. Poll the session within its expiry window without logging tokens.
  4. Test account vitals and capture only non-sensitive status fields.
  5. Enable warmup or campaign assignment only after an explicit change approval.
  6. Poll background jobs and produce per-account success and failure evidence.

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
provider=google; accounts=3; assign-campaign=false

Expected handoff:

text
oauth=complete; vitals=3/3; mutation=awaiting-owner
