power-systems

power-systems is a skill for Claude Code, Codex from devideamax/aerospace-team. It costs 124 tokens per session (6,836 once invoked), scanned A, original, no licence file.

Spacecraft power-systems engineering plans how a spacecraft generates, stores, and distributes electrical power. It includes solar arrays, batteries, eclipse operation, and radioisotope generators.

In plain words
What is it for?
Use it to size solar arrays, select batteries, calculate eclipse energy balance, estimate RTG needs, and build power budgets for spacecraft subsystems.
Why use it?
It helps ensure the spacecraft has enough energy during sunlight and darkness, including periods when solar panels cannot generate power. This supports informed choices about the power architecture.

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

power-systems 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 4d 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 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.

power-systems is a skill published in the GitHub repository devideamax/aerospace-team (21 stars, last pushed 6mo ago), with no licence file. It adds 124 tokens to every session and 6,836 once invoked, about $0.0006 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 2026-08-30.
