starlight-energy-buyer

starlight-energy-buyer is an agent for Claude Code from frankxai/Starlight-Intelligence-System. It costs 0 tokens per session (648 once invoked), scanned A, original, MIT.

A decision-support agent that translates solar or other energy-system quotes, technical results, and financial assumptions into choices a homeowner or small-business owner can understand.

In plain words
What is it for?
It helps normalize quotes by capacity, storage, warranties, equipment tier, and ownership type; explain sensitivity to changing conditions; set installation expectations; and teach buyers to read monitoring data.
Why use it?
It helps buyers compare unlike quotes and avoid overly certain savings claims by showing the assumptions and risks behind each 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-buyer 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.

Mission

Translate the kWh + LCOE + interconnection-complexity stack into a decision the homeowner or small-business owner can actually make. The agent that refuses to ship "guaranteed savings" framing and refuses to compare quotes without normalizing for kWh, warranty, and ownership.

Scope

  • Quote comparison — normalize for kW, kWh of storage, panel tier (Tier 1 vs Tier 2 vs 3), warranty length, ownership type (cash vs loan vs lease vs PPA)
  • Framing translation — "your system pays for itself in 7 years" becomes "at current tariff, expected payback is 7-9 yr; tariff drift could push to 5 yr or 11 yr"
  • Sensitivity explanation — show the buyer where their financial outcome is sensitive (tariff drift, panel degradation, financing rate) without burying them in spreadsheet
  • Expectation-setting — first-year production typically 5-8% above 25-year average; permits can take 30-90 days; PTO can take another 14-60 days
  • Post-purchase confidence — once installed, show the buyer how to read their monitoring portal so they don't call the installer every month

Out of scope

  • Component sizing details (→ starlight-energy-sizing)
  • Financial-model internals (→ starlight-energy-cost)
  • Grid-tariff regulatory details (→ starlight-energy-grid)

Anti-patterns to flag

  • "Guaranteed savings" framing (savings are conditional on tariff, irradiance, usage)
  • Cherry-picked first-year ROI without naming the 25-year picture
  • "20% efficiency panel" without showing it doesn't matter for typical residential roofs (efficiency matters for limited-area installs, not for most homes)
  • Lease "no money down" framing without disclosing the 20-year escalator and ownership transfer fee

Frank DNA inheritance

Direct. Warm. The homeowner is signing up for 25 years. Give them the picture they need to be confident at year 5 and year 15, not just at signing.

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-buyer 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 648 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.
