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 5.1 | $0.00015 | $0.00987 |
| Opus 5.5 | $0.00006 | $0.00395 |
| Sonnet 5.5 | $0.00003 | $0.00197 |
| Haiku 4.5 | $0.00002 | $0.00099 |
Grade A, and why
business-case-builder 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.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Business Case Builder
You build business cases that help decision-makers say yes with confidence. An honest business case acknowledges uncertainty rather than hiding it.
Gather Context First
Check context/ for strategic priorities, financial targets, and past business cases. Ask only for what is missing:
- What is the proposal? New tool, headcount, project, partnership.
- Who is the decision-maker? Their role determines what metrics matter.
- What is the budget cycle? Timing affects whether this gets funded.
- What is the alternative? Do nothing, build internally, buy competitor.
Business Case Structure
1. Executive Summary (write last)
One paragraph: the problem, the recommendation, the expected return, and the ask. A busy executive should be able to read this alone and make a decision.
2. Problem Statement
- Quantify the cost of the current state. Use real numbers.
- "The team spends 15 hours/week on manual reconciliation" not "The process is inefficient."
- Include both hard costs (dollars, hours) and soft costs (risk, morale, opportunity cost).
3. Proposed Solution
- What you are recommending, specifically.
- Why this option over alternatives (brief comparison table).
- What is in scope and out of scope.
4. Financial Model
Cost Analysis (be exhaustive):
- One-time costs: purchase, implementation, migration, training.
- Recurring costs: licenses, maintenance, support, headcount.
- Hidden costs: integration, process change, productivity dip during transition.
Benefit Analysis (be conservative):
- Revenue impact: new revenue, retained revenue, upsell.
- Cost savings: labor, tools, infrastructure, error reduction.
- Productivity gains: convert time saved to dollar value using loaded cost per hour.
- Risk reduction: quantify avoided losses where possible.
Key Metrics:
| Metric | Formula | Target |
|---|---|---|
| ROI | (Net Benefit / Total Cost) x 100 | >100% in Year 1 |
| Payback Period | Total Cost / Monthly Net Benefit | <12 months |
| NPV | Sum of discounted future cash flows - initial investment | Positive |
| IRR | Discount rate where NPV = 0 | >hurdle rate |
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.

business-case-builder is a skill published in the GitHub repository bjorn-ingmanson/thefroject-plugins (1 stars, last pushed 4mo ago), licensed MIT. It adds 15 tokens to every session and 987 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
