A read-only skill for reporting a Hunter account’s plan, remaining credits, and usage. Hunter is a service for finding and verifying professional email addresses.

Use it to see remaining search or verification credits, the current plan, and the reset date.

It lets you check quota and reset information without consuming credits or changing the account.

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	$0.00043	$0.00413
Opus 5.5	$0.00017	$0.00165
Sonnet 5.5	$0.00009	$0.00083
Haiku 4.5	$0.00004	$0.00041

Security

Grade A, and why

check-usage 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 1mo 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.

What it actually says

Check Usage

Read-only view of the account's plan, credits, and usage. No credits consumed, no changes made.

Examples

/hunter:check-usage How many credits do I have left?
"What plan am I on?"
"How many searches have I used this month?"
"Show my account details"

Steps

Read the account → Get-Account-Details for plan and reset date; Get-Usage for search/verification consumption and what's remaining. Neither tool returns a team name — don't show one.
Present a clear summary — show what's REMAINING, not the allowance. Use requests.credits.remaining when the account has a single credits bucket; otherwise compute available - used per bucket. (available is the period allowance plus packs, not what's left.)

# Account Usage

| | Used | Remaining | Resets |
|--|------|-----------|--------|
| **Searches** | 320 | 180 | 2026-08-01 |
| **Verifications** | 140 | 860 | 2026-08-01 |

**Plan:** Starter

If the user is close to a limit, flag it: "You've used 90% of your monthly searches — they reset on [date]."

Credit Cost

Free — reading account details and usage consumes no credits.

Important Notes

Read-only. This skill never creates API keys, changes the plan, or edits account settings — those stay in the Hunter dashboard.
Handy as a pre-check before running bulk verification or enrichment.

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.
