A freelancer-workflow skill for tracking time, calculating billable work, preparing invoices, and analyzing projects across multiple clients.

It connects hours worked to client billing and project results, reducing manual calculations and making profitability easier to review.

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	$0.00075	$0.01524
Opus 5.5	$0.00030	$0.00610
Sonnet 5.5	$0.00015	$0.00305
Haiku 4.5	$0.00007	$0.00152

Security

Grade A, and why

memstack-business-freelancer-toolkit 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 2mo 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.

Freelancer Toolkit: Setting up freelancer workflows...

Produces time tracking sheets, invoice calculations, and project analytics for freelancers managing multiple clients.

Activation

Trigger	Status
User says "track my time" or "billable hours"	ACTIVE
User says "freelancer invoice" or "client billing"	ACTIVE
User says "freelance finances" or "project hours"	ACTIVE
User wants a formal proposal or SOW	NOT this skill, use Proposal Writer or Scope of Work
User wants a generic invoice template	NOT this skill: use Invoice Generator

Context Guard

Do NOT use for proposal writing (that's proposal-writer)
Do NOT use for scope of work documents (that's scope-of-work)
Do NOT use for generic invoice templates (that's invoice-generator)
This skill covers the full freelancer workflow: tracking time → calculating billable → generating invoice → analyzing profitability

Steps

Step 1: Gather freelancer context

Parameter	Default	Example
Hourly rate	Ask	$150/hr, $85/hr
Currency	USD	EUR, GBP, AUD
Billing cycle	Monthly	Weekly, per-project
Clients	Ask	Acme Corp, StartupX
Tax rate	0% (user adds)	20% VAT, 25% self-employment

Step 2: Time tracking sheet

Create or update a tracking spreadsheet (CSV or markdown):

# Time Log: [Month Year]

## [Client Name]

| Date | Project | Task | Hours | Billable | Notes |
|------|---------|------|-------|----------|-------|
| 2026-04-01 | Website Redesign | Homepage wireframes | 3.5 | Yes | Completed v1 |
| 2026-04-01 | Website Redesign | Client feedback call | 0.5 | Yes | Revision notes |
| 2026-04-02 | API Integration | Auth endpoint | 4.0 | Yes | |
| 2026-04-02 | Internal | Admin/invoicing | 1.0 | No | Non-billable |

**Subtotal:** 8.0 billable hours / 9.0 total hours

Time tracking rules:

Log daily, reconstructing from memory loses hours
Separate billable from non-billable (admin, learning, invoicing)
Round to nearest 15 minutes (0.25 hr increments)
Include project and task for accurate per-project reporting
Notes field captures context for invoice line items
