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

fullenrich-event-attendees 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 13d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/lib/csv.mjs, scripts/lib/fullenrich-client.mjs, scripts/lib/fullenrich-webhook.mjs, …), 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

FullEnrich Event Attendees

Turn a list of LinkedIn event attendees into an SDR-ready CSV with verified work emails and mobile phones, using the FullEnrich 20-vendor waterfall.

When This Skill Applies

  • "enrich attendees of this event {URL}"
  • "enrich this attendees CSV"
  • "scrape and enrich LinkedIn event {URL}"
  • "FullEnrich event attendees"

Two input modes

The skill does NOT bundle a LinkedIn event scraper. LinkedIn doesn't expose event attendees through any clean public API and Unipile's surface area doesn't cover events either. So the skill ships with two input paths and the user picks:

Mode A — CSV file (recommended). Bring an attendees CSV from any source:

  • Manual copy-paste from the LinkedIn event page
  • PhantomBuster "LinkedIn Event Attendees Export" automation
  • Evaboot Sales Navigator export filtered to event registrants
  • Any other tool

Mode B — Apify actor (BYO). The user configures an Apify actor (e.g. giovannibiancia/linkedin-events-partecipants-scraper) under their own Apify account, supplies their LinkedIn cookies via env vars, and the skill runs it. The skill does not pin a specific actor — the user picks one and provides the actor input shape via --actor-input if its keys differ from the defaults.

What This Skill Does NOT Do

  • Does not include a built-in LinkedIn event scraper. Pick mode A or B above.
  • Does not write outreach copy. Pair with personalize-message after.
  • Does not push to a CRM.
  • Does not spend FullEnrich credits without explicit user approval. See "Credit safety contract" below.

Credit safety contract (MANDATORY)

This skill spends FullEnrich credits, which cost real money. Safeguards:

  1. Always shows current balance before doing anything.
  2. Always shows estimated cost of the run.
  3. --max-credits N ceiling (default 500) — auto-trims the contact list to fit.
  4. Hard-approval prompt — blocks on stdin until the user types yes. Non-TTY without --yes aborts.
  5. --dry-run mode — parses input + computes cost preview without spending a credit.

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.
