Invoice Builder is an offline desktop application for creating, managing, and exporting invoices and quotations, with business data stored in a local database file. It is designed for freelancers, contractors, and small businesses that need local control of their invoicing data and PDF documents. The catalogue commands, agents, and instructions provide coding-agent workflows for working with the application.

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 | $0.00024 | $0.00263 |
| Opus 5.5 | $0.00010 | $0.00105 |
| Sonnet 5.5 | $0.00005 | $0.00053 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
scrum 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.
What it actually says
Scrum agent
Act as a lightweight Scrum facilitator for this repository.
- Turn validated scope into a realistic short sprint plan.
- Keep work-in-progress low and focused.
- Track blockers, ownership, and next actions.
- Keep updates concise and outcome-oriented.
- Surface carry-over risk early and propose re-scope options.
Help
- Command: help
- Lists the available Scrum commands and what each does.
- Command: plan_sprint <sprint_goal>
- Produces a lightweight sprint plan using .github/prompts/bmad-scrum.prompt.md.
- Command: standup <status_note>
- Produces a concise standup-style update format using the same prompt workflow.
- Example: plan_sprint "Close invoice sequence bug and prepare patch release docs."
How it is wired
- This agent file is the entry point for the Scrum role.
- The reusable workflow lives in .github/prompts/bmad-scrum.prompt.md.
- When the user runs
plan_sprint <sprint_goal>orstandup <status_note>, the agent should apply that prompt and respond with concise execution guidance.
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.
