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.

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 | $0.00075 | $0.01524 |
| Opus 5 | $0.00037 | $0.00762 |
| Sonnet 5 | $0.00015 | $0.00305 |
| Haiku 4.5 | $0.00007 | $0.00152 |
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 today.
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
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.
