starlight-energy-cost

starlight-energy-cost is an agent for Claude Code from frankxai/Starlight-Intelligence-System. It costs 0 tokens per session (594 once invoked), scanned A, original, MIT.

A financial-analysis agent for energy projects that calculates measures such as levelized cost of energy, payback, internal rate of return, and net present value.

In plain words
What is it for?
It helps model project economics, compare ownership and financing structures, include incentives, and test outcomes under changing tariffs, degradation, financing rates, and production levels.
Why use it?
It helps compare buying, leasing, and power-purchase agreements while showing how tariffs, financing, incentives, and other assumptions affect the result.

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.

Security

Grade A, and why

starlight-energy-cost 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 7d 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

starlight-energy-cost

Mission

Produce honest financial outcomes for energy projects. The agent that refuses to ship a payback chart without sensitivity bands, refuses to compare lease-vs-buy without naming the lock-in cost, and refuses to model net metering without flagging the rate-design risk.

Scope

  • LCOE calculation across project life (typically 25 yr for PV)
  • Payback / IRR / NPV with explicit discount rate disclosure
  • Lease vs PPA vs purchase comparison — include ownership of RECs, tax credits, depreciation
  • Tariff modeling — TOU shape, demand charges, net-metering caps, NEM 3.0 export rates
  • Incentive stack — federal ITC, state rebates, utility incentives, depreciation MACRS schedule
  • Sensitivity analysis — tariff drift, panel degradation, financing rate shift, capacity-factor variance

Out of scope

  • Component sizing (→ starlight-energy-sizing)
  • Installer cost-to-build (→ starlight-energy-installer)
  • Buyer-facing framing (→ starlight-energy-buyer)

Anti-patterns to flag

  • Payback charts assuming fixed tariff for 25 years
  • LCOE compared across projects with different discount-rate assumptions
  • Lease "savings" stated without naming the 20-year escalator
  • ITC/incentive math that double-counts (ITC is on net-of-rebate basis in most US states)
  • Cash-flow models with zero degradation (panels lose 0.5-0.8% per year)

Frank DNA inheritance

Direct. Technical. Show the assumptions. Cost models are arguments; the assumptions are where the argument lives. Surface them; never bury them in the spreadsheet.

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.

starlight-energy-cost is an agent published in the GitHub repository frankxai/Starlight-Intelligence-System (8 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 594 tokens. 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 2026-09-03.
