Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Security

Grade A, and why

cold-email-campaign 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 11d ago.

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.

Cold Email Campaign

What this does

Run a full cold-email campaign as a files-only workflow: no account, no API keys, no platform push, no sending. You gather (or produce) client research, write a campaign plan (1 broad ICP + 1 offer + N segments), define portable search filters, qualification rules, and segmentation, then for every segment produce strategy, reviewed email copy, and AI personalization prompts. When the pipeline finishes, the workspace holds a ready-to-send sequence the user can load into their own list tool and sending platform.

Workspace

Create a campaign workspace at ./cold-email/{slug}/, where {slug} is a short lowercase hyphenated name for the client or campaign (for example acme-outbound or fintech-founders). Put all plan-level and segment-level files under that folder. Do not invent platform config files; the free workflow stops at markdown artifacts.

./cold-email/{slug}/
├── research.md
├── plan.md              # H1 = campaign name; 1 ICP + 1 offer + N segments
├── search-strategy.md
├── qualification.md
├── segmentation.md
├── 0 - default/         # strategy.md, emails_v2.md, prompts.md
└── 1 - {segment}/

Layout rules:

  • plan.md has a single top-level # {Campaign Name} H1.
  • Always scaffold 0 - default/ as the catch-all segment (broadest messaging for contacts that do not fit a numbered segment).
  • Numbered segments use N - {segment-slug}/ (for example 1 - healthcare-saas/, 2 - fintech-founders/). Create one folder per segment defined in the plan.
  • Each segment folder holds strategy.md, emails.md (draft), emails_v2.md (reviewed), and prompts.md.

Pipeline

Run the steps below in order. Name each skill when you invoke it so the user can see progress. Write every artifact into the workspace before moving on.

1. Research

If research.md is missing and the user has not already provided enough context (notes, call transcripts, site copy, offer one-pager), run client-research (or ask them to paste notes, transcripts, or site text). Write or confirm research.md at the workspace root. Do not invent an ICP or offer.

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.
