An integration with lemlist, a service for running email outreach campaigns and managing the contacts involved. It reads and writes campaign, lead, activity, team, and related data through lemlist's API.

Use it to list campaigns, retrieve leads, add or update contacts, delete leads, and inspect campaign activity and performance data.

It removes the need to handle campaign and contact data manually in lemlist or write API requests yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00088	$0.01694
Opus 5	$0.00044	$0.00847
Sonnet 5	$0.00018	$0.00339
Haiku 4.5	$0.00009	$0.00169

Measured 8d ago against content hash 7d6374b6c936, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

lemlist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/add_leads.py, scripts/auth.py, scripts/delete_lead.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Lemlist Skill

Fetch and manage data from the lemlist API.

Quick Start

All scripts follow a file-first pattern:

Accept an optional --output directory (defaults to ./output)
Save raw JSON and processed CSV into that directory
Return JSON with {"output_files": [...], "summary": "..."}

Authentication

Set the LEMLIST_API_KEY environment variable:

export LEMLIST_API_KEY="your-api-key"

Get your API key from lemlist Settings > Integrations > API.

What ships with it

12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
