Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00066 | $0.00888 |
| Opus 5 | $0.00033 | $0.00444 |
| Sonnet 5 | $0.00013 | $0.00178 |
| Haiku 4.5 | $0.00007 | $0.00089 |
Grade A, and why
company-lists 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.
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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Company Lists
Save companies and organize them into lists and folders — the account-level counterpart to lead-lists.
Examples
/hunter:company-lists Save these fintech companies to a "Target Accounts" list"Save stripe.com to my prospects""Add these Discover results to a new list""Move the EU accounts into a Europe folder""Copy these companies to my Q3 list"
Workflow
Step 1: Save companies
- Save a single company →
Save-Company(from a domain or a Discover / enrichment result). - Companies typically come from the discover skill (
Find-Companies) or company-enrichment.
Step 2: Create or pick a list
- New list →
Create-Company-Listwith a descriptive name. - Existing →
List-Company-Liststo browse, then use its ID.
Step 3: Populate
- Add saved companies →
Add-Company-To-List. - Remove →
Remove-Company-From-List. - Move / copy in bulk across lists →
Bulk-Move-Companies/Bulk-Copy-Companies. - Note: list membership and bulk move/delete require static lists; bulk copy requires only the destination static (its source may be dynamic). Dynamic (auto-filter) lists can't be the target of these ops — pick a static target when the user chooses from
List-Company-Lists.
Step 4: Organize
- Favorite / unfavorite →
Favorite-Company-List/Unfavorite-Company-List. - Folders →
List-Company-List-Folders,Create-Company-List-Folder(requires both anameand acolor— ask the user or pick one; unlike leads-list folders, Hunter won't default it),Update-Company-List-Folder(renames/recolors a folder). To file a list into a folder, callUpdate-Company-Listwith the targetcompany_list_folder_id— the folder tool only edits folder metadata, not membership. - Rename →
Update-Company-List; read →Get-Company-List.
Step 5: Present summary
# Company List: Target Accounts
**Companies:** [count]
## Next Actions
1. Find contacts at these companies (domain-search skill)
2. Save decision-makers as leads (manage-leads / lead-lists skills)
3. Run a full prospecting pass on the list (prospecting skill)
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.

company-lists is a skill published in the GitHub repository hunter-io/claude-plugin (9 stars, last pushed 6d ago), licensed MIT. It adds 66 tokens to every session and 888 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
