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 | $0.00017 | $0.01284 |
| Opus 5 | $0.00009 | $0.00642 |
| Sonnet 5 | $0.00003 | $0.00257 |
| Haiku 4.5 | $0.00002 | $0.00128 |
Grade A, and why
engineering-budget 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 8d 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.

Engineering Budget & Resource Planning
When to Use
- Annual/quarterly budget planning for engineering
- Headcount forecasting and hiring plans
- Infrastructure cost modeling and optimization
- Calculating ROI for technical projects/initiatives
- Justifying technical investments to stakeholders
Budget Categories
1. People Costs (typically 60-75% of eng budget)
Headcount Plan:
┌──────────────────────────────────────────────────────┐
│ Role │ Current │ Q+1 │ Q+2 │ Q+3 │ Q+4 │
│ Sr Engineer │ 5 │ 6 │ 7 │ 7 │ 8 │
│ Mid Engineer │ 3 │ 4 │ 4 │ 5 │ 5 │
│ Jr Engineer │ 2 │ 2 │ 3 │ 3 │ 3 │
│ Tech Lead │ 1 │ 1 │ 2 │ 2 │ 2 │
│ DevOps/SRE │ 1 │ 1 │ 1 │ 2 │ 2 │
│ QA │ 1 │ 1 │ 2 │ 2 │ 2 │
├──────────────────────────────────────────────────────┤
│ Total │ 13 │ 15 │ 19 │ 21 │ 22 │
│ Cost/month │ XXk │ XXk │ XXk │ XXk │ XXk │
└──────────────────────────────────────────────────────┘
2. Infrastructure (typically 15-25%)
- Cloud hosting (AWS/GCP/Azure)
- Database services (RDS, Atlas)
- CDN, storage, bandwidth
- Monitoring & observability (Datadog, New Relic)
- CI/CD (GitHub Actions, CircleCI)
- Security tools (Snyk, SonarQube)
3. Tools & Services (typically 5-15%)
- IDE licenses (JetBrains, GitHub Copilot)
- SaaS integrations (Stripe, SendGrid, Twilio)
- Design tools (Figma)
- Project management (Jira, Linear)
- Communication (Slack)
ROI Calculation Framework
ROI = (Net Benefit / Cost) × 100
Where:
Net Benefit = Revenue Gain + Cost Savings - Implementation Cost
Example — Implementing caching layer:
Revenue Gain: R$0 (não gera receita direta)
Cost Savings: R$15k/mês (redução de 40% na conta AWS)
Implementation: R$30k (2 engineers × 2 weeks)
Payback Period: 30k / 15k = 2 meses
Annual ROI: ((15k × 12) - 30k) / 30k × 100 = 500%

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.

engineering-budget is a skill published in the GitHub repository camilooscargbaptista/cto-toolkit (7 stars, last pushed 5mo ago), licensed MIT. It adds 17 tokens to every session and 1,284 once invoked, about $0.0001 per session on Opus 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.
